It was meant to wipe out the U.S. Navy. Check out all of Moscow's military dreams. Here's What You Need to Remember: Many of the Soviet bombers of the post-war era were direct analogues to US types. The Tu-4, in fact, was a direct copy of captured American B-29s. The Sukhoi T-4 was the USSR’s answer to the B-70 Valkyrie. A massive, incredibly fast bomber capable of high altitude flight, the T-4 tested (and in many ways exceeded), the limits of the Soviet Union’s defense industry. Designed to hit Mach 3, with a service ceiling of around 70,000’, the T-4 resembled the B-70 visually, and in capability. However, because the organization of airpower in the Soviet Union differed from that of the United States, T-4s were also considered for tactical missions, such as reconnaissance and the delivery of anti-ship missiles. The idea of a T-4 carrying Kh-22 anti-ship missiles is very scary indeed.
