August 14, 2025 (by Lieven Dewitte) - Poland has finalized a $3.8 billion agreement with the United States to modernize its fleet of 48 F-16C/D block 52+ fighters to the F-16V (Viper) standard, significantly enhancing its NATO-aligned air combat capabilities.

The modernization program will upgrade 36 single-seat and 12 twin-seat F-16s. Work will occur at Polandβs Military Aviation Works No. 2 in Bydgoszcz, with two aircraft flown to the U.S. for testing. The remaining jets will be upgraded domestically between 2028 and 2038.
Upgrades include the Northrop Grumman AN/APG-83 AESA (SABR) radar, next-gen mission computers, helmet-mounted display systems, Sniper advanced targeting pods, upgraded electronic warfare suites (e.g., Viper Shield), Auto-GCAS, and structural improvements extending service life to 12,000 flight hours.
Enhancements will boost integration with F-35A jets, Abrams tanks, Apache helicopters, and multi-domain operationsβa critical leap as Poland finalizes orders for 32 F-35A "Husarz" and raises defense spending to 5% of GDP by 2026.
Given rising tensions from Russiaβs war in Ukraine, this modernization program enhances deterrence and consolidates Polandβs position as a key eastern NATO bulwark. The upgraded F-16V fleet will support missions such as Baltic Air Policing and rapid responses to regional threats.
The agreement is part of a broader $7.3 billion U.S. Foreign Military Sale (FMS) package approved in October 2024.
