Soyuz 13

  1973-103A

To compensate for delays in the DOS program, Mishin's engineers modified an old-style 7K-T with solar panels to carry a scientific payload including the Orion-2 ultraviolet telescope and a multispectral camera. The payload was mounted in the nose of the BO, replacing the docking system. 11F615A8 No. 33 was launched in Dec 1973 on an 8 day mission with crew Pyotr Klimuk and Valentin Lebedev.
