1973-041A
Following the failures of Almaz OPS 1 and DOS 3 in Apr-May 1973, a 7K-T ferry craft, 11F615A8 No. 36, was launched on a two day test mission. This version of the 7K-T would become the standard, with no solar panels and space for a crew of two in spacesuits. Soyuz 7K-T No. 36 was given the code name Kosmos-573.
