One of the things we used to have was the USSR, which meant we also had the Cold War. That gave us “the three-minute warning”, fallout shelters, Mutually Assured Destruction, vast military-industrial complexes, spies and defectors and assassinations, and all manner of political posturing that nowadays all looks a bit farcical but was quite scary at the time. It also gave us some very effective-looking military aircraft. On both sides. Here are some Soviet ones.
The Tupolev Tu-28 was, and remains, the largest and heaviest fighter ever to see service. The Myasishchev M-50 was a prototype – only one was ever built. A second prototype, designated M-52, was built but never flew. The Sukhoi T-4 was also a prototype, and was never given a NATO reporting name.
