Sukhoi T-3

Starting in the early 1950s, the development of the T-3 proceeded in parallel with the S-1 which would eventually become the Sukhoi Su-7.

[1] Aside from the wings, the two aircraft shared the basic design as well as the Lyulka AL-7 turbojet engine.

Since the T-3 was intended to be an interceptor, it was fitted with the Almaz (Алмаз, Diamond) radar housed in the air intake.

The T-3 was ordered into production at Factory No.153 but events overtook it when a revised specification was issued for the Interceptor fighter role.

[1] Although not proceeded with, the T-3 served as the basis for what would eventually become the Sukhoi Su-9, forming the backbone of the PVO during the 1960s.
