November 14, 2025 (by Lieven Dewitte) - The United States is working to speed up the manufacturing of the F-16V “Viper” fighter jets ordered by Taiwan, after the island’s defence ministry reported a series of production delays.
Taiwan’s Ministry of National Defence informed lawmakers that the delivery schedule for all 66 new F-16V aircraft—originally slated for completion by the end of 2026—had been pushed back due to factors including production line relocations and supply-chain disruptions.

According to the ministry, 50 of the jets are already on the assembly line, and 10 are expected to undergo flight testing in 2025, with delivery targeted for 2026.

In response to the delays, contractors for the programme have instituted two 20-hour shifts per day to accelerate production rates and meet contractual commitments.

Beyond the F-16 order, Taiwan also faces delays for other US defence systems: the AGM-154C Joint Standoff Weapon glide bombs and MK-48 torpedoes have moved from 2026 to 2027-28 delivery timelines due to similar supply chain issues. Meanwhile, the High Mobility Artillery Rocket Systems (HIMARS) are reportedly arriving ahead of schedule.

Why it matters:

• The F-16V upgrade is a key element of Taiwan's plan to maintain air-superiority in the face of growing military pressure from mainland China.
• Delays in delivery could limit Taiwan’s front-line readiness at a time when tensions in the Taiwan Strait continue to rise.
• Taiwan’s request for accelerated production underscores the importance of reliable delivery timelines for advanced defence platforms.

Lockheed Martin, the manufacturer of the jets, said it remains committed to delivering “mission-critical capabilities” while working with the U.S. government to maintain safe compliance. Taiwan says it will continue to closely monitor progress, adjust payment schedules accordingly, and ensure that future deliveries align with its defensive needs.
