Third TKS flight that would have docked with the cancelled Almaz OPS 4 military space station. The spacecraft was instead flown unmanned to Salyut 7 as Cosmos 1686. For that mission the VA reentry capsule was retained but stripped of its heat shield and all recovery equpment. In their place military optical test sensors (infrared telescope and Ozon spectrometer) were installed.
