The F-15E Strike Eagle is the world's leading dual-role fighter, performing air-to-ground and air-to-air missions with unmatched success. The F-15 was the first U.S. fighter to have engine thrust greater than the normal weight of the aircraft, allowing it to accelerate while in a vertical climb. The F-15 constantly is upgraded to include state-of-the-art equipment. It can penetrate enemy defenses and can outperform and outfight any current or projected enemy.
