This 1980 translated Air & Cosmos article (via a CIA report), "Cosmonaut Klimuk Describes 'Soyuz T' Mission Plans," might be of interest:
On 1 February 1980 in Paris, where he was attending the Young Communist Congress, Soviet Cosmonaut Peter Klimuk revealed to us that the USSR will continue to utilize simultaneously all three types of space transport vehicles at its disposal: the "Progress" automatic freight transport, the conventional "Soyuz" manned vehicle and the new "mixte" "Soyuz-T" vehicle.
