(VIDEO) 500th F-35A Lightning II Joins U.S. Air Force Fleet, Cementing Fifth-Generation Air Superiority Against China and Russia

(DEFENCE SECURITY ASIA) — The U.S. Air Force has achieved a dramatic milestone in its quest for fifth-generation supremacy with the delivery of its 500th F-35A Lightning II to the Florida Air National Guard.

The stealth fighter’s arrival at the 125th Fighter Wing in Jacksonville signals not only a generational leap for the Guard but also a decisive message to rivals in Moscow, Beijing, and Tehran.

The Florida-based wing, known as “The Thunder,” becomes the fourth Air National Guard unit to transition from the aging F-15C/D Eagle to the F-35A, a move that symbolizes the sweeping modernization of America’s air combat arsenal.

The unit is set to integrate up to 20 F-35As over the coming years, gradually retiring its Eagles while operating a mix of loaned F-35s to ensure uninterrupted combat readiness.

Lt. Col. Joseph Pasko, commander of the 159th Fighter Squadron, made clear the strategic significance of the aircraft.

“These new F-35s, which include the Air Force’s 500th, represent the forefront of fifth-generation airpower,” he said.

“We expect to play an integral role in potential future conflicts, and our citizen-Airmen stand ready to answer the nation’s call; anytime, anywhere.”

The F-35A brings unmatched advantages in stealth, sensor fusion, and electronic warfare, making it a keystone of the U.S. Air Force’s Agile Combat Employment (ACE) doctrine, which prioritizes dispersal, rapid redeployment, and resilience against peer adversaries.

For the Pentagon, the deployment of F-35s to the Florida Air National Guard is not just about replacing older fighters, but about positioning advanced airpower close to the Caribbean, Latin America, and the Atlantic — regions where both Russian and Chinese influence are expanding.

Brig. Gen. Richard L. Coffey underscored the strategic value of Jacksonville’s location, saying, “The Guard’s ability to field fifth-generation aircraft in key regions gives combatant commanders the reach, resilience and rapid response they need. Jacksonville’s strategic location and joint partnerships expand the Air Force’s options and ensure our Airmen are at the forefront of our nation’s defense.”

To accommodate the F-35, Jacksonville Air National Guard Base has undergone sweeping infrastructure upgrades, including a new simulator complex, climate-controlled weapons facilities, and widened taxiways to support stealth operations.

Col. Carl Guckenberger emphasized the human factor behind the transition, stating, “Modern hardware and software demand modern skill sets. Our Airmen have embraced the challenge, directly supporting the conversion efforts while simultaneously completing thousands of hours of formal training so our jets are ready to launch on time and on target.”

Lockheed Martin, the prime contractor, celebrated the 500th aircraft milestone, noting that the global fleet now exceeds 1,200 aircraft, flown by over 3,000 pilots who have collectively logged more than one million flight hours.

“We join the United States Air Force in celebrating the delivery of 500+ F-35s to their squadrons, adding to the combat-proven, global fleet that ensures peace through strength for the U.S. and our allies,” a spokesperson stated.

Globally, the F-35 is transforming allied airpower, with deployments stretching from NATO’s northern flank in Europe to Israel in the Middle East, and Japan, South Korea, and Australia in the Indo-Pacific, cementing a multinational fifth-generation coalition unmatched by Russia’s Su-57 or China’s J-20.

The U.S. Air Force still plans to acquire 1,763 F-35As, though budget pressures have slowed procurement, with only 24 requested for fiscal 2026 as resources shift toward spares and sustainment.

Analysts warn that while procurement has fluctuated, the urgency of matching China’s expanding J-20 stealth fleet and Russia’s upgraded Su-57M1 program may force Washington to accelerate deliveries in the late 2020s.

If procurement stabilizes at 48 jets annually, the F-35A will surpass the F-16 by 2030 to become the most numerous U.S. fighter, securing its role as the backbone of America’s airpower well into the mid-21st century.

Future upgrades under the Block 4 program promise enhanced stealth, a new adaptive-cycle engine, expanded weapons integration — including hypersonic munitions — and AI-enabled sensor fusion to keep the F-35 ahead of emerging threats.

Additional bases are also planned at Moody Air Force Base in Georgia and Misawa Air Base in Japan, further strengthening forward-deployed deterrence against both Russia in Europe and China in the Pacific.

The delivery of the 500th F-35A Lightning II is more than a numerical achievement.

It is a signal to the world that the United States is consolidating its position as the undisputed leader in fifth-generation air dominance while preparing for a future where airpower will decide the fate of wars against peer rivals.
