The Soviet built Mikoyan-Gurevich MiG-25 bomber and interceptor aircraft entered into service in 1970. With a top speed of Mach 3.2, powerful radar, and 4 air-to-air missiles, the MiG-25 was a formidable opponent. Before entering operational service, 4 MiG-25Rs were flown over Israel roughly 20 times.
