الطائرة اف-35 بي F-35B Lightning II
The F-35B short takeoff/vertical landing (STOVL) variant is the world’s first supersonic STOVL stealth aircraft. It is designed to operate from austere bases and a range of air-capable ships near front-line combat zones. It can also take off and land conventionally from longer runways on major bases. The U.S. Marine Corps' F-35B aircraft reached initial operational capability (IOC) on July 31, 2015, and as of January 2017, a squadron of F-35Bs is permanently based at MCAS Iwakuni, Japan.
الطائرة أف-35 سي F-35C Lightning II
More than 50 years of aircraft carrier-based fighter evolution culminates in the F-35C. Never before has low observable stealth been available at sea. The F-35C carrier variant (CV) is the world’s only 5th Generation, long-range stealth strike fighter designed and built explicitly for carrier operations.The U.S. Navy is the largest customer receiving F-35Cs, with the U.S. Marine Corps also planning to acquire the C variant in addition to the F-35B.

فيراري 488 Ferrari 488
With a mid-mounted twin-turbo 3.9-liter V-8, the 488GTB generates a sonorous wail and ferocious acceleration all the way to 8000 rpm, where it makes 661 hp. A seven-speed dual-clutch automatic is the sole transmission; we estimate a zero to 60 time of 3 seconds. Ferrari’s adaptive suspension is relatively compliant without sacrificing handling. The Pista version makes 710 hp. For those who want more V-8 music, the Spider offers a retractable hardtop that raises or lowers at speeds up to 25 mph.
