MiG-25 Foxbat [Russia]

It was designed specifically to intercept the American B-70 Mach 3 bomber, which never went into service. It has set a number of records, such as carrying the world's largest air-to-air missiles - The AA-6 "Acrid", and an astonishing record of climbing from rest to 35,000 metres in just 4 minutes 11 seconds.
