What is f 28 fighter jet?

The F-28 fighter jet does not exist. It is possible that you meant the F-22 fighter jet, which is a stealthy air superiority fighter developed by Lockheed Martin for the United States Air Force. It entered service in 2005 and has a top speed of Mach 2.25 (approximately 1,500 mph or 2,410 km/h). Its advanced avionics and weapons systems make it a highly capable fighter jet, capable of engaging multiple targets at once and executing sophisticated aerial maneuvers. Its stealth features, including its specialized coatings and design, give it a low radar cross-section, making it difficult to detect and engage by enemy forces.
