This week: the Ministry of National Defense warns that some sales are in peril due to budgetary constraints; the Navyโ€™s Hai Kun indigenous submarine finishes testing; the Air Force announces a plan to buy upgraded C-130H Hercules; and the MND announces additional PAC-3 MSE missiles on the way to Taiwan, alongside weekly awards and solicitations.

MND Announces LOA Extensions for Missiles, Paladins

On Friday, the MND announced that they would be seeking extensions to Letters of Offer and Acceptance (LOAs) for several arms sales announced in December, including TOW and Javelin anti-tank missiles, and Paladin self-propelled howitzers. LOAs are a critical first step in the Foreign Military Sales implementation process that sets out payment schedules and delivery timelines for items, and if not signed by March 15, the above cases would be subject to cancellation or renegotiation. Per the MND, the LOAs have not been signe,d and initial payments have not been made owing to ongoing battles in the Legislative Yuan over the special defense budget, including dueling proposals worth NT$1.25 trillion that the MND requested, and one worth NT$400 billion advanced by the opposition.

Hai Kun Submarine Continues Testing Exercises

With Taiwan’s indigenously produced Hai Kun submarine conducting its most recent underwater test of flare and decoy deployment, the first phase of the programโ€™s testing has officially come to a successful end. These tests off the coast of Kaohsiung included deep water dives with the submarine reaching 150 meters, and shallow water tests to verify the submarineโ€™s stability and watertightness. The second phase of testing, its timing having not been announced, will consist of sonar, combat system, and maneuver-torpedo tests. Taiwanese military and political officials plan to use this new phase to verify the reliability of the Hai Kun.

ROCAF Announces Plan to Buy Upgraded C-130Hs

Taiwanโ€™s Air Force has essentially abandoned its midโ€‘life โ€œTaiwushan IIIโ€ plan to upgrade all 20 Cโ€‘130H airlifters, moving instead to buying 10 new C-130J “Super Hercules,” after U.S. cost estimates ballooned from around NT$100 billion for cockpit and avionics upgrades to more than NT$250 billion once FAA certification and structural reinforcements were included.  According to Central News Agency reporting, the cancelled program aimed to integrate digital flight displays, improve maritime searchโ€‘andโ€‘rescue systems and add simulators, but senior officers said software costs and airframe reinforcement made the investment uneconomical. Under the new plan, the Air Force will pursue a โ€œhighโ€“low mixโ€: the advanced Cโ€‘130J, with more powerful engines, sixโ€‘bladed propellers and a fully digital cockpit, will handle demanding missions like nighttime and austere operations, while the remaining Cโ€‘130Hs will get domestic upgrades and support routine transport tasks.

Additional PAC-3 MSE Missiles Confirmed by MND

On Wednesday, MND sources confirmed that Taiwan is receiving 102 PAC-3 Missile Segment Enhancement (MSE) missiles for Patriot air defense systems, to be paid using surplus funds from a Patriot procurement program. This sale appears in our Arms Sales Backlog as a 2022 plus-up (modification) from a 2010 sale of Patriot systems to Taiwan, and includes the addition of 1-2 missiles, likely for testing. This tranche of PAC-3 MSEs is in addition to a planned, but not officially notified, future sale of Patriot batteries and PAC-3s that will be paid using the special defense budget.

Weekly Awards/Solicitations

Last Thursday, the All-Out Defense Mobilization Agency awarded Xinshifu Co., Ltd and Shencai Fashion Industry Co., Ltd a NT$142.85 million (US$4.53 million) contract for digital camouflage-patterned tents. The contract will be fulfilled nationwide.

On Monday, the Armaments Bureau solicited bids for combat battle vests, worth NT$868.40 million (US$27.70 million).

On Tuesday, the Naval Command awarded a NT$195.00 million (US$6.22 million) contract to the American Institute in Taiwan for the assessment of the use of underwater technology. The contract will be fulfilled in Taipeiโ€™s Zhongshan District and Taoyuanโ€™s Longtan District, respectively.

This week: MND announces that NASAMS will be deployed to current SHORAD units, a status update on last Abrams tank deliveries emerged, the MND released a policy document with details about naval, wheeled vehicle, and missile procurement, and the Air Force expressed interest in buying new early warning aircraft, alongside weekly awards and solicitations.

NASAMS To Be Given to Antelope, 20mm AD Units

As part of Taiwanโ€™s ongoing air defense modernization, the MND announced this week that US-sold National Advanced Surface-to-Air Missile System (NASAMS) medium-range air defense batteries will replace Antelope and 20-mm short-range capabilities currently used by air-defense units. Per our Taiwan Arms Sales Backlog, this case remains in progress since its notification in November 2024, though a recent US$698.95 million (NT$21.8 billion) U.S. Army production contract awarded to Raytheon for the first three NASAMS fire units signals the beginning of the manufacturing phase, with completion expected by 2031.

Last Tranche of Abrams Tanks to Arrive by March

Taiwanโ€™s MND reported that it would receive its final batch of 28 M1A2T Abrams tanks by March of this year, confirming an MND report to the LY submitted in May 2025. This will be the third batch of Abrams, originally approved in July 2019 sent from the United States to the Taiwanese Army. The first batch of 38 tanks arrived in December 2024, being commissioned in October 2025; and the second batch, sent in July 2025, is still awaiting commissioning; totaling 108 tanks. The sale, which remains backlogged until delivery is confirmed, is worth $1.28 billion USD (NT$40.52 billion).

MND Releases Procurement Policy Document

On Friday, the MND released their โ€œList of Regulated Military Products for the Second Half of 2025,โ€ a policy document outlining controlled procurement items and timelines for future projects, including naval vessels, wheeled vehicles, and indigenous missile programs.

Most importantly, the Navy listed plans to procure several classes of vessels, including five next-generation light anti-air frigates, five light anti-submarine frigates, two rescue ships, one submarine rescue ship, one new Yushan-class dock landing ship, and one oil/ammunition replenishment ship. These projects have a total estimated cost of NT$315 billion (US$9.97 billion) and are expected to be built between 2027 and 2040.

The MND also announced plans to produce 500 additional Clouded Leopard infantry fighting vehicle variants equipped with 105mm cannons, alongside 468 โ€œreconnaissance and tactical wheeled vehicles,โ€ beginning in 2028. Lastly, the list announced plans to procure 2 launchers and 128 missiles for the Strong Bow anti-ballistic missile defense system, still under development and part of the proposed โ€œT-Domeโ€ air defense system.

Air Force Briefed by L3Harris on AEW Aircraft Buy


Per UpMedia, the Air Force Command recently received a briefing from American defense contractor L3Harris on options for commercial procurement of early-warning aircraft. This comes after repeated requests for procurement of E-2D Hawkeye aircraft and MH-60R Black Hawk anti-submarine helicopters were blocked by the United States, and the Air Forceโ€™s desire to upgrade aging early warning airframes. L3Harris is the primary manufacturer of the EA-37B Compass Call aircraft, a modified Gulfstream G550 business jet that has recently been commercially sold to other US allies, including Italy.

Weekly Awards/Solicitations

Last Thursday, the Naval Command awarded Van Halteren Technologies a NT$756.06 million (US$23.89 million) open-ended contract for naval โ€œdrive and controlโ€ spare parts. The contract will be fulfilled throughout the southern region of Taiwan, including Kaohsiung.

Also on Thursday, the Air Force Command awarded a NT$589.83 million (US$18.64 million) contract to Rheinmetall Italia SPA for maintenance of aircraft training simulator systems. This contract is to be fulfilled throughout the southern region of Taiwan.

On Friday, the Naval Commandโ€™s Magong Logistics Support Command made a repeat bid solicitation for the renovation of Magong Naval Baseโ€™s mobilization depot, worth NT$49.00 million (US$1.55 million).

On Monday, the Army Logistics Command solicited bids for rifle magazine bags, worth NT$32.48 million (US$1.03 million).

On Wednesday, the Air Force Command solicited bids for a high-voltage power supply renovation turnkey project at Tainan Air Base, part of Tainan Airport, worth NT$402.67 million (US$12.75 million).

This week: US and Taiwanese companies partner on drones, a former ROCA commander reveals details about the sale of Abrams tanks to Taiwan, the TPP issues their own special budget proposal, the Navy prepares dive tests on its Hai Kun submarine, alongside weekly awards and solicitations.

Taiwanese GTOC and US Companies Partner on Drones

On Friday, Taiwanese company G-Tech Optoelectronics Corp. (GTOC) and US companies Aerkomm and Firestorm Labs signed strategic partnerships to establish a military-grade drone industrial chain in Taiwan. GTOC Chairman Huang Kun-chien stated at the event that the Ukraine conflict has changed thinking on drone usage, and that supply chain resilience is critical. Firestone Labs was founded just before the Ukraine war as an innovator, while Aerkomm brings significant aerospace and satellite communications to the partnership. As a part of the strategic partnership, the three companies will embark on โ€œdecentralized production [and] localized supportโ€ models to produce drones.

Ex-Army Commander Reveals Abrams Sale Expedited

Former Army Deputy Commander Lt. Gen. Huang Kuo-ming told Liberty Times this week that the sale of M1 Abrams tanks to Taiwan was actually directly negotiated with the American Institute in Taiwan (AIT), the United Statesโ€™ de facto embassy, bypassing the Ministry of National Defenseโ€™s normal procedures. Huang stated that the MND was focusing on air and naval capabilities, while the Army urgently needed new tanks. Huang proposed that the Army go directly to the AIT and received permission from the Armyโ€™s then-commander. When the AIT was receptive to the idea of the sale, Gen. Huang then sent then-Col. Huang Wen-chi to the US to brief US officials on the sale. According to Gen. Huang, the MND was surprised when the sale was announced to hear that the Army had already been in discussions with the US on its own.

TPP Issues Special Budget Proposal, Cuts to NT$400 Billion

On Monday, the Taiwan Peopleโ€™s Party (TPP), an opposition party in the Legislative Yuan, released its proposal for a special defense budget, reducing the budget ceiling from NT$1.25 trillion (US$40 billion) to NT$400 billion (US$12.74 billion) and mandating additional oversight. On Tuesday, the MND held its own press conference in opposition to the TPPโ€™s proposal, criticizing it as hasty and unprofessional, and providing clarification. Director of the MND Strategic Planning and Operations Department, Maj. Gen. Huang Wen-chi, provided background on project development and the Five-Year Force Structure Plan, stating that the TPPโ€™s proposal would not allow for revision of project documents within an appropriate timeline, and that additional oversight is not required as each project must undergo audits by the MNDโ€™s Audit Department alongside LY oversight.

Navyโ€™s Hai Kun Submarine Undergoes Dive Tests

On Wednesday, CSBC announced that the Navyโ€™s Hai Kun indigenous submarine will conduct its first dive trial off Kaohsiung on Thursday, 29 January. Construction on Hai Kun began in November 2020, its keel was laid in November 2021, and it last completed sea trials in June 2025. The testing program has been beset by technical problems, including hydraulic issues and a main engine failure, and has drawn criticism over cost overruns and inefficiencies. CSBC has pushed back, arguing that Hai Kun is cheaper than comparable South Korean or Australian programs and should be considered a โ€œmid-rangeโ€ submarine in terms of price.

Weekly Awards/Solicitations: Ammunition, Ship Parts

On Thursday, the Army Command awarded a NT$238.03 million (US$7.58 million) contract to Shaoteng Construction Co. for renovation of 30-mm cannon training facilities. The contract will be fulfilled in Kaohsiung City. 30-mm cannons are used on the CM34 variant of the Clouded Leopard APC.

On Friday, the Naval Command awarded a NT$1.39 billion (US$44.37 million) contract to Wartsila Taiwan, Ltd., for main engine spare parts and logistics support services for naval vessels. The contractโ€™s fulfillment location was not stipulated.

On Monday, the Tactical Control Wing, Air Force Command awarded an NT$735.58 million (US$23.54 million) contract to NCSIST for reconnaissance radar auxiliary facility maintenance. The contract will be fulfilled in Wufeng Township, Hsinchu County. This is likely for the Air Force Surveillance and Early Warning Center, a PAVE Phased Array Warning System with a purported range of ~3,000 nautical miles.

On Wednesday, the Army Ordnance Maintenance and Development Center, Army Logistics Command awarded a NT$288 million (US$9.22 million) contract to the Armament Bureauโ€™s 209th Factory for commercial repair and maintenance of 40-mm grenade launcher variants of the CM-32/33 Clouded Leopard APC. On the same day, the Center also awarded a NT$186 million (US$5.95 million) contract to NCSISTโ€™s Manufacturing Center for commercial repair and maintenance of 30-mm autocannon turret systems on CM-34 Clouded Leopard APCs. Both contracts will be fulfilled at the Centerโ€™s headquarters in Jiji Township, Nantou County.

Also on Wednesday, the Armaments Bureau awarded a NT$1.07 billion (US$34.10 million) contract to Cheng Yuen International Co. and Taiwan HoYa International Co. for 7.62-mm blank cartridges and 3 other ammunition items. The contract will be fulfilled in Dashu District, Kaohsiung City.

Weekly Arms Sales Tracker: 1/21/26

This week: the MND announced โ€œfour more salesโ€ not notified to the US; Minister Koo revealed the quantity of ALTIUS systems Taiwan is buying, additional news on production line enhancement emerged; and the US Congress released two appropriations bills with funding for Taiwan, alongside weekly awards and solicitations.

MND Reveals โ€œFour More Salesโ€ from US Soon

Per Vice Minister of National Defense Hsu Szu-chien on Thursday, at least four additional arms packages have yet to be notified to the US Congress, on top of Decemberโ€™s US$11 billion sale packages. Hsu did not reveal what those additional items would be, but likely four Patriot launchers and more PAC-3 MSE interceptors would be included, as MND officials had already announced.

Minister Koo Reveals Number of ALTIUS Systems from December Sale

In a closed-door LY committee briefing Monday on the NT$1.25 billion special defense budget, Minister of National Defense Wellington Koo revealed the previously undisclosed number of ALTIUS systems Taiwan would be procuring, from its December US$1.1 billion (NT$34.54 billion) package. Koo stated that 1,554 ALTIUS-700M loitering munitions and 478 ALTIUS-600 ISR UAVs would be part of that package, and that Taiwan would also be procuring around 200,000 unmanned aerial vehicles of all types and 1,000 unmanned surface vehicles.

Additional Details on Production Line Enhancement

MND officials released additional details on production line enhancement projects to be paid for under the NT$1.25 trillion special defense budget, including what factories would be focusing on. Per plans, the 202nd Factory will accelerate 155mm artillery shell production, of which only Paladin self-propelled howitzers use in Taiwan (with plans to sell surplus production). The 205th Factory will work to produce small arms ammunition, 50 million primers per year in peacetime, and up to 70 million primers during wartime. The 209th Factory will continue work on โ€œvarious new armored vehicle assembly lines,โ€ including Yunqiao โ€œClouded Leopardโ€ armored personnel carriers and a next-generation 105-mm combat vehicle. Finally, the 401st Factory will accelerate efforts on production of night-vision goggles and chemical protective masks.

US State, Defense Appropriations Bills: Funds for Taiwan

On Thursday, the US House of Representatives passed a combined appropriations bill package known as a โ€œminibusโ€ (or โ€œmini-omnibusโ€) for executive agencies, including the Department of State. This package included US$300 million in Foreign Military Financing for Taiwan, with a proviso that the Secretary of State โ€œprioritizeโ€ delivery of defense articles to Taiwan. The appropriations bill also provided for FMF loan authority to Taiwan and prohibited funds from being spent on maps that inaccurately show Taiwanโ€™s geographical holdings.

On Tuesday, both houses of Congress released a conference text of a second โ€œminibusโ€ bill, including appropriations for the Department of Defense. This bill included US$1 billion appropriated for the Taiwan Security Cooperation Initiative (TSCI), a program established in 2025 to provide defense articles, services, and training to Taiwan. This appropriation is in line with an earlier provision in the Fiscal Year 2026 National Defense Authorization Act. The billโ€™s conference report also directs the Secretary of Defense to submit a spend plan to Congress for that program. The bill also appropriates US$150 million for replacement of defense articles or reimbursement for services provided to Taiwan, designed to backfill depleted stocks. Line items indicate that this was requested to be $1 billion, but was reduced by appropriators.

Weekly Awards/Solicitations: Helo, IDF Sim Maintenance

On Monday, the Army Ordnance Maintenance and Development Center, Army Logistics Command awarded a NT$288.00 million (US$9.10 million) contract to the Armament Bureauโ€™s 202nd Factory for commercial maintenance of two items: 40mm remote-controlled gun turrets (excluding sights) and armored vehicle fire suppression systems. On the same day, the Center also awarded a NT$47.85 million (US$1.51 million) contract to NCSISTโ€™s Manufacturing Center for maintenance of short-range automated defense weapons systems. Both contracts will be fulfilled at the Centerโ€™s headquarters in Jiji Township, Nantou County.

On Tuesday, the Air Force Command awarded a NT$92.80 million (US$2.93 million) contract to Aerospace Industrial Development Corporation for maintenance of Indigenous Defense Fighter (IDF) simulators, including cockpit subsystems. This contract will be fulfilled at Ching Chuan Kang Air Base in Daya District, Taichung City; and Tainan Air Base, in South District, Tainan City.

Also, on Tuesday, the Army Command awarded a NT$1.08 billion (US$34.12 million) contract to Air Asia Co., for โ€œstrategic maintenanceโ€ of Army transport helicopters. The location of this contractโ€™s fulfillment was not stipulated. This contract may consist of arming currently held UH-60 Black Hawk helicopters, of which plans were announced last week by MND officials.

Taiwan Arms Sale Backlog, December 2025 Update

Trump Administration Notifies Congress of $11 Billion in New Taiwan Arms Sales

By Eric Gomez and Joseph Oโ€™Connor

On December 17, 2025, the Trump administration notified Congress of over $11 billion worth of new Foreign Military Sales (FMS) cases to Taiwan, the largest ever package of US arms sales to Taiwan by dollar value. This new package raises the total dollar value of the US arms sale backlog to Taiwan to approximately $32 billion. At least $4.4 billion of this amount has been partially delivered to Taiwan.

Seeing such a steep growth in the total dollar value of the backlog seems alarming at first glance, but overall, the December 2025 FMS cases are a good thing for Taiwan. The new arms sales are heavily weighted in favor of asymmetric systems that will likely be produced and delivered rapidly.

As always, Figure 1 shows how the backlog is divided between traditional systems, asymmetric systems, and munitions. Table 1 is an itemized list of the FMS cases that Taiwan is waiting to receive, with the latest information on delivery schedules. In Table 1, items in green text are new additions to the backlog; those in red text are newly delivered items that have been removed from the backlog, and yellow/orange text represents arms sales worth at least $1 billion that are partially delivered.

Breaking Down the December Package

The Arms Export Control Act requires that Congress receive notification of new FMS cases above a certain dollar threshold before those cases can advance. After notification, Congress has a specified period, depending on the recipient country (30 days in Taiwanโ€™s case), during which it can block the sale by passing a joint resolution of disapproval. If Congress does not pass such a resolution, then the FMS sale goes ahead. Congressional notifications are how Taiwan Security Monitor establishes its universe of arms sales for the backlog.

The $11 billion package contains eight unique FMS cases. The new cases are heavily weighted in favor of asymmetric capabilities, which represent five cases worth approximately $6.9 billion. The other three sales are for one traditional capability (Paladin self-propelled howitzers) and two maintenance sales (spare and repair parts for Harpoon missiles and attack helicopters).

The distinction between asymmetric capabilities, traditional capabilities, and munitions is explained in a November 2023 article by Eric Gomez, published with the Cato Institute, during the nascency of the backlog dataset. Additionally, the two maintenance sales have not been added to the backlog because they support capabilities that Taiwan already possesses, and tracking the delivery of spare parts is not possible with the available data.

Asymmetric Capabilities: 5 Cases, $6.9 Billion

The most heartening aspect of the December 2025 FMS package to Taiwan is its heavy emphasis on asymmetric weapons systems. Taiwan has historically under-invested in asymmetric capabilities, which are less flexible, but tend to be less expensive, more mobile, and harder for Chinaโ€™s military to counter in a high-intensity conflict.

When Gomez published the first version of the Taiwan arms backlog dataset in late 2023, asymmetric capabilities were $4.2 billion out of $19.17 billion, or 22 percent. With the December 2025 arms sales, these numbers are now $14.7 billion out of $32 billion, or 46 percent. This growing emphasis on asymmetric capabilities is a step in the right direction for Taiwan.

The five December 2025 asymmetric capabilities arms sales are:

  1. HIMARS launchers and munitions, $4.05 billion
  2. ALTIUS loitering munitions/drones, $1.1 billion
  3. Tactical Mission Network, $1.01 billion
  4. Javelin Missiles, $375 million
  5. TOW Missiles, $353 million

There are several things to note with this mix of capabilities:

Firstly, the two largest arms sales in this categoryโ€”HIMARS rocket artillery launchers and ALTIUS dronesโ€”are on efficient production lines, which means they will likely be delivered to Taiwan relatively quickly. According to Taiwanโ€™s Ministry of National Defense, a December 2022 sale of HIMARS launchers and munitions that should arrive in 2026 is the only FMS case out of 14 that is considered ahead of schedule. ALTIUS drones likewise have arrived in Taiwan rapidly, with an initial tranche arriving in Taiwan (August 2025) only a little over one year after Congress was notified of the sale (June 2024).

Secondly, our dataset codes Javelin and TOW missiles as asymmetric weapons and not munitions because both FMS cases include other systems besides the missiles themselves that make it more appropriate to see them as an asymmetric capability rather than just munition reloads. The Javelin sale includes additional launcher units, while the TOW sale includes kits to mount launchers to Humvee vehicles.

Finally, once Taiwan receives the 82 HIMARS launchers from the December sale on top of the 29 from previous arms sales, it will have the second-largest inventory of HIMARS in the world after the United States. HIMARS has demonstrated its value as an asymmetric, long-range precise rocket artillery system in the ongoing war in Ukraine, and it is in high demand in Taiwan, alongside many frontline NATO countries. The range and mobility of HIMARS make it an excellent choice for an asymmetric defense strategy.

Traditional Capabilities: 1 Case, $4.03 Billion

The only traditional capability in the December 2025 arms sale package is the sale of 60 M109A7 Paladin self-propelled howitzers plus support equipment such as ammunition carriers and armored recovery vehicles. Taiwan previously attempted to purchase 40 M109A6 Paladins in 2021, but shortly after the Ukraine war began, the sale was cancelled, and Taiwan instead focused on buying additional HIMARS.

Taiwan could have probably found better ways to spend $4 billion, but in the world of traditional capabilities, self-propelled howitzers are not that bad an investment. Artillery pieces are still important in modern battlefields, and while it may not be as mobile as a HIMARS launcher, a Paladin can still use mobility to improve its survivability. Taiwan also already operates earlier variants of the Paladin, which should help with the quick absorption of the new systems. Finally, the defense industrial base has improved its production rates of 155mm artillery shells and Paladin howitzers because of the Ukraine war, which will hopefully mean a shorter gap between Congressional notification and delivery to Taiwan.

Stinger Delivery Completed

While the massive recent arms sale package has understandably received most of the attention this month, there were two arms sales that were removed from the backlog. Taiwan was waiting on the delivery of 500 Stinger man-portable air defense missiles that were sold across two FMS cases (December 2015 and July 2019) worth a combined $440 million.

Though Taiwan originally planned on purchasing just 250 for the Navy, and got relatively close to finalizing a contract a few years after the 2015 notification to Congress, the Taiwanese Army desired Stingers of its own, halting progress on the sale to allow for renegotiations. A 2024 MND document further mentions that supply chain issues and material shortages exacerbated by the COVID-19 pandemic contributed to sluggish progress on Stinger production, and that since 2021, there have been two official letters of protest submitted about the project.

A budget unfreezing report from earlier in 2025 and testimony by Defense Minister Wellington Koo to the Legislative Yuan in November indicated that Taiwan would finally receive a delivery of 500 Stingers, which would satisfy the two FMS cases, by the end of 2025. Taiwan has reportedly developed plans to purchase approximately 2,000 additional Stingers from the United States, but such a sale has not yet received Congressional notification.

Other Case Updates: F-16 Testing and IRST Production

News emerged about the status of F-16V production this month, as the first Taiwanese airframe, #6831, underwent taxiing tests on December 20 and a flight test on December 30, both at Lockheed Martinโ€™s production facility in Greenville, South Carolina. Delivery of the aircraft and additional testing of more airframes are expected to begin early this year. Once the first airframe arrives in Taiwan, we will mark the F-16 case as being a delivery in progress.

On December 31, the U.S. Air Force awarded a $328.5 million undefinitized contract action (UCA) to Lockheed Martin for production of three types of targeting pods, including Sniper, IRST, and LANTIRN pods. Of this, 55 IRST pods are to be produced for the ROCAF, using $157.3 million worth of FMS funds for Taiwan, and work is expected to be completed by June 2031. It is worth noting that a UCA is expressly not final in terms of cost and quantity, but authorizes production of those systems. The last update for the IRST case was in June 2024, when a contract was signed for production.

Conclusion

The December 2025 arms sale package significantly increases the size of the backlog while also improving its underlying composition. Unlike previous FMS cases that added slow-to-deliver, traditional capabilities like F-16s and Abrams tanks, the new cases prioritize asymmetric systems, which will likely have faster production times and have a lower per-unit cost. A Taiwanese military that is better prepared to implement an asymmetric defense strategy should be able to impose costs on China through dispersed fires, expendable unmanned systems, and mobile air defense.

This update also highlights the main challenge for 2026: closing the gap between FMS notification to Congress and weapons in the hands of Taiwanโ€™s soldiers. The recently completed Stinger cases show how even sales of asymmetric capabilities can be slowed down by bureaucratic inefficiencies, supply chain disruption, and defense industry bottlenecks. Maintaining progress on HIMARS, ALTIUS, and other asymmetric programs will require ongoing prioritization by both governments, transparent delivery timelines, and consistent follow-through on training, basing, and sustainment.

Taiwan Arms Sale Backlog, November 2025 Update

New Report to LY, Special Budget, and NASAMS Contracts

By Joseph Oโ€™Connor and Eric Gomez

While November 2025 did not see any major topline activity in the backlog itself, the second Trump administration made its first maintenance sale of aircraft parts to Taiwan, valued at $330 million. Additionally, many valuable status updates emerged from a new MND report to the Legislative Yuan on arms sales, alongside regular hearings. Taiwanese President Lai Ching-te also publicly announced Taiwanโ€™s special budget for the first time, which will not directly affect the backlog but signals additional purchases in the future.

The U.S. arms sale backlog to Taiwan as of November 30, 2025, remains $21.54 billion. For arms sales valued at over $1 billion, deliveries in progress are marked in yellow-orange in our visualizations, meaning that the true dollar value is lower than the topline. Figure 1 illustrates the breakdown of the backlog between asymmetric weapons, traditional weapons, and munitions. Table 1 provides an itemized list of all arms sales in the backlog, including the most up-to-date information on their status.

Novemberโ€™s Report to LY and Other Status Updates

On November 3rd, the MND submitted a report to the Legislative Yuan on the status of US arms sales, noting a total of 25 FMS cases that are ongoing, up from 18 in June 2025. The report classified three major sales as โ€œdelayed,โ€ namely, F-16 Block 70/72 aircraft, AGM-154C Joint Standoff Weapons (JSOWs), and MK 48 torpedoes, corresponding with earlier statements in October from Minister of National Defense Wellington Koo about delays associated with those sales.

On AGM-154C JSOWs: The report indicates they will continue to be delayed, with delivery not expected until 2027 or 2028, instead of 2026; in line with Premier Cho Jung-taiโ€™s statements in October to that same effect. The AGM-154C has been categorized as a delayed sale by the MND since March 2024, and a contract to produce them was not signed until February 2024.

On MK 48 torpedoes: Novemberโ€™s report categorizes them as delayed for the first time, slipping from 2026 to 2028 and a closeout of 2030, per statements made by the Navyโ€™s Chief of Staff, Vice Adm. Chiu Chun-jung, after the LY report was submitted.

Though known for a while, the November report categorized the sale of 18 HIMARS launchers, 20 ATACMS missiles, and 864 GMLRS rockets as โ€œahead of schedule,โ€ expected by the fourth quarter of 2026, instead of the projected timeline of 2027. This is likely owing to significant production increases on the US side. Koo, while testifying to the LY concerning the monthly report, also stated that sales of Stinger and Harpoon missiles were on schedule.

A few other status updates appeared in November, from various MND announcements and statements by officials. First, Air Force Chief of Staff Lt. Gen. Lee Ching-jan informed the LY on November 6th that the first two MQ-9B SeaGuardian maritime surveillance drones will be delivered to Taiwan by the third quarter of 2026, continuing on a normal timeline. The MND announced on November 11th that as a part of the โ€œT-Domeโ€ air defense concept, batches of the 100 total PAC-3 MSE interceptors will begin arriving by the end of 2025, with expected completion by 2027. Lastly, Director of the MND Strategic Planning Department Maj. Gen. Huang Wen-chi stated that delivery of the 6 total MS-110 reconnaissance pods will begin in batches before the end of 2025.

The inclusion of these monthly reports by the MND to the LY is a useful and transparent step in determining the status of all sales, but, in particular, those that the MND considers โ€œdelayed.โ€

Lai Announces Special Budget Publicly

On November 25, President Lai Ching-te publicly announced, via a speech and an opinion piece in the Washington Post, a special defense budget worth NT$1.25 trillion (US$40 billion) for โ€œstrengthening defense resilience and asymmetric capabilities.โ€ This also included additional statements echoing Lai’s earlier calls to raise defense spending to 3.3% of GDP by 2026 and 5% by 2030.

What this means for the current backlog is unknown, but as of December 2025, significant new arms sales appear to be associated with the special budget funding announced here. Our analysis of the new sales is already published, but additional information about those sales and their relationship to the special budget will be included in the December 2025 backlog update.

NASAMS Update and FMS Sale

Two other major updates regarding backlogged sales also merit consideration. First, on November 17th, the U.S. Department of Defense announced a new contract award to Raytheon for the production of three National Advanced Surface-to-Air Missile System (NASAMS) fire units for Taiwan, worth $698.95 million (NT$21.8 billion). Expected to finish in spring 2031, this is part of a $1.16 billion sale of NASAMS approved in October 2024. Owing to this contractโ€™s timeline, it is expected that NASAMS will be an extremely delayed sale in the future.

On November 13th, the Defense Security Cooperation Agency notified Congress of a new sale to Taiwan of non-standard spare parts for use in F-16, C-130 and Indigenous Defense Fighter (IDF) aircraft, worth US$330 million (NT$10.28 billion). This marks the first sale during the second Trump administration (and as of the time of writing, certainly not the most recent), the last being approved in December 2024, 329 days prior. Maintenance sales are not counted toward the backlog because they support weapons already in Taiwanโ€™s possession, unlike weapons that have not been delivered, and tracking the delivery status of maintenance equipment is difficult given publicly available information.

Conclusion

The more frequent publication of reports on arms sale timelines to the LY is an encouraging and transparent step from Taiwanese officials. It is worth noting that there are many more than three sales that are delayed, but the MND only appears to categorize โ€œdelayedโ€ sales as those that Taiwan has paid for. TSM is working on a complete translation of Kooโ€™s testimony before the LY that we will publish in the new year; and will also have a more in-depth response to the issue of Taiwanese perception between โ€œdelayedโ€ and โ€œbackloggedโ€ sales.

As of the time of writing, there are many new developments in Taiwanese arms sales, in particular, the addition of a US$11 billion arms package. We at TSM will provide more detail on what that means for the backlog next month.

New Arms Sales for Taiwan: Details and Reactions

Author: Joe O’Connor


On Wednesday evening, the U.S. Defense Security Cooperation Agency and Department of State notified Congress and the public of eight proposed arms sales to Taiwan worth US$11.1 billion in total, confirming reporting from Reuters only hours before. Counted together, this is the largest single arms sale in Taiwanโ€™s history. Below is a detailed accounting of each sale and its contents, along with reactions from the Taiwanese Presidential Office and the PRCโ€™s Taiwan Affairs Office and Ministry of Foreign Affairs.

What Is Being Sold?ย 

It is worth prefacing that the below sales are mostly building on current capabilities that Taiwan has, either by expanding stockpiles (in the case of HIMARS, Javelins, TOWs, and ALTIUS) or receiving upgraded versions of equipment (in the case of the Paladins). This is significant as it means that Taiwan has determined how to use these capabilities and is not introducing new platforms that would require additional training time.

HIMARS: The single largest sale in this package, at US$4.05 billion (NT$127.2 billion), consists of 82 HIMARS launchers, 420 Army Tactical Missile System (ATACMS) missiles, 756 Guided Multiple Rocket Launch System (GMLRS) unitary rocket pods, 447 GMLRS-Alternative Warhead (GMLRS-AW) rocket pods, and 39 High-Mobility Multipurpose Wheeled Vehicles (HMMWV or Humvees). This sale comes after a plus-up sale approved in December 2022 for 29 HIMARS launchers, 20 ATACMS, and 144 GMLRS pods; as of December 2025, Taiwan has only received 11 launchers and is expected to receive the remaining 18, plus munitions, in 2026.

M109A7 Paladin Self-Propelled Howitzers: Worth US$4.03 billion (NT$126.6 billion), this sale consists of 60 Paladins, 60 M992A3 Carrier Ammunition Tracked Vehicles (CATVs), 13 M88A2 Recovery Vehicles, 4,080 Precision Guidance Kits, and 42 International Field Artillery Tactical Data Systems (IFATDS), as well as an unspecified number of M2A1 machine guns and M795 155-mm ammunition. This sale is expected to be half of the proposed 120 Paladins, a deal that was reduced from 168 and then cancelled by Taiwanโ€™s Ministry of National Defense in 2022 due to concerns about delays caused by the war in Ukraine.

ALTIUS-700M and 600 Systems: Worth US$1.10 billion (NT$34.54 billion), this sale consists of an unknown quantity of ALTIUS-700M loitering munitions and ALTIUS-600 intelligence, surveillance, and reconnaissance systems. A previous sale of 291 ALTIUS-600M-V loitering munitions was authorized in June 2024, and an unknown quantity was delivered in August 2025, with all expected to be delivered by the end of this year.

Tactical Mission Network: Worth US$1.01 billion (NT$31.71 billion). The congressional notification for this sale appears to refer to it as a single network, and per Janes, it is a concept explored recently by the U.S. Special Operations Command to โ€œoperationalize chat and data-sharing environmentsโ€ similarly to platforms such as Signal and WhatsApp. The sale also includes unspecified unmanned aerial systems as well as software.

Javelin Missiles: Worth US$375 million (NT$11.78 billion), consisting of 1,050 Javelin FGM-148F missiles, 10 Javelin fly-to-buy missiles, and 70 Javelin Lightweight Command Launch Units (LwCLUs). The last Javelin sale authorized to Taiwan was in December 2015, and was modified in 2019 to total 400 missiles and 46 LwCLUs. Despite delays owing to the war in Ukraine, those Javelins were delivered in July 2024, per an October 2024 MND report cited by TSM Fellow Eric Gomez.

TOW-2B Missiles: Worth US$353 million (NT$11.08 billion), consisting of 1,545 TOW-2B BGM-71F-7-RF missiles, 16 TOW-2B fly-to-buy missiles, and 24 Improved Target Acquisition Systems. Taiwan was last authorized sales of TOW missiles in December 2015 and July 2019, having all 1,700 across both sales delivered in December 2024, despite the original timeline stating delivery in 2022.

AH-1W Helicopter Spare/Repair Parts: Worth US$96 million (NT$3.01 billion), consisting of an unknown quantity of AH-1W SuperCobra helicopter unclassified spare and repair parts. This is a routine maintenance sale for AH-1Ws that Taiwan was authorized to buy in July 1997.

Harpoon Missile Repair Follow-on Support: Worth US$91.4 million (NT$2.87 billion), consisting of an unknown quantity of Harpoon radar seekers, as well as return, repair, and reshipment of Naval Harpoon missiles. This is a routine maintenance sale for what appears to be RGM-84 Harpoons on ROCN vessels, as opposed to the Harpoon Coastal Defense System authorized in 2020 or air-launched Harpoons approved in 2022.

Reaction to the Sales

Immediately after the announcement, a spokesperson for Taiwanโ€™s Presidential Office stated that they were โ€œsincerely grateful to the US government for once again demonstrating that it continues to fulfill its security commitments.โ€ The spokesperson also noted it was the โ€œsecond arms sale to Taiwan announced during the Trump administration,โ€ and reiterated statements made previously by Lai administration officials concerning increased defense spending to 3% of GDP by 2026 and 5% by 2030. No statements have thus far been made by Taiwanโ€™s Ministry of Foreign Affairs, Ministry of National Defense, or TECRO Mission in the United States.

In Beijing, the news of the sale was met with a flurry of condemnations from several PRC state organs. Chinaโ€™s Ministry of Foreign Affairs commented on the sale in a press conference on Thursday, condemning it and promising to โ€œtake resolute and strong measures to defend its national sovereignty, security, and territorial integrity.โ€ Additionally, the Taiwan Affairs Office of the State Council, an organ responsible for cross-Strait relations, accused Taipei of โ€œseeking independence by relying on the U.S.โ€ and said such sales would turn Taiwan into a โ€œpowder keg.โ€

In Washington, however (as of the time of writing, Thursday morning), there have been no statements aside from the initial DSCA congressional notifications, including none from senior members of the Senate and House Foreign Affairs Committees, or Secretary of State Marco Rubio. The American Institute in Taiwan also has not commented.

What Does This Mean?

This batch of proposed sales represents a large commitment on the part of the Trump administration to support Taiwan, but is not immune from challenges. Legislative Yuan approval of the DPPโ€™s proposed NT$1.25 trillion special budget is hamstrung by KMT and TPP opposition legislators, who demurred on placing it on the agenda until President Lai testified, an action that the LY cannot compel (causing a minor constitutional crisis). This threatens to delay delivery of not only current sales, but also these future ones, particularly if the special budget is cut or fails to pass.

The issue of production challenges also merits consideration. HIMARS production has increased, so much so that the MND has classified its remaining 18 launchers from the 2022 sale to be ahead of schedule, and it is likely that these additional HIMARS will not be excessively delayed. A potential decrease in support to Ukraine also means that Paladins and Javelins could be focused on Taiwan instead, decreasing timelines further. But it merits remembering that currently (not counting these recent sales), over US$21 billion in already authorized equipment is delayed, including F-16C/D Block 70s and AGM-154C Joint Standoff Weapons, due to production issues.

Watching the progress of the special budget through the LY, as well as other arms developments, will be valuable in determining how these new sales will work. Overall, however, this is an encouraging development for Taiwanโ€™s security.
