The Ye-6 was the definitive tailed delta prototype leading directly to the MiG-21.

The MiG-21F was evolved from the Ye-6T and was the first version of the tailed delta fighter to be built in large numbers.

The I-75F all-weather interceptor developed in competition with the Sukhoi T-40 in the mid-'fifties.

The Ye-2A was a parallel development to the tailed deltas that evolved as the MiG-21. A series of 30 was built.
