Red Valkyrie

My latest at the National Interest takes a look at the Soviet T-4, a bomber that fulfilled some of the same missions as the XB-70 Valkyrie:

The Soviet Union, aware of the development of the Valkyrie, embarked on at least two programs in response. One was the MiG-25 “Foxbat,” a high-speed interceptor capable of catching the killing the Valkyrie. The other was the Sukhoi T-4, which bore an uncanny resemblance to the Valkyrie itself. And like the Valkyrie, the T-4 resulted in a remarkably innovative aircraft that now resides only in a museum.
