The F-35A Lightning II is a fifth-generation multirole stealth fighter developed by Lockheed Martin. It is designed for a variety of missions, including air-to-air combat, air-to-ground strikes, and intelligence gathering. The aircraft features advanced avionics, sensor fusion, and low observable technology, making it difficult to detect by radar. The F-35A is part of the larger F-35 program, which includes variants for the U.S. Navy and Marine Corps. It is intended to replace older aircraft like the F-16 Fighting Falcon and enhance the capabilities of the U.S. Air Force and allied nations.
