It managed to dock to Mir on the third attempt after the crew removed a trash bag from the docking collar in a space walk. The FGB tug, its work done, then backed away from the station. But the manoeuvres had cut into its already-reduced propellant supply. Unable to deorbit itself to a controlled burn-up in the atmosphere, the FGB was instead commanded to boost itself into a storage orbit 40 km above Mir.

Energia was to deliver the military Skif-DM Polyus battle station into orbit. Due to delays in completion of the enormous static test facility at Baikonur, which could test the entire Energia vehicle stack, it was decided to launch the vehicle without the verification the tests would provide. The launch of 6SL was planned for 21:30 Moscow time. It was delayed five hours when a leak was detected in the Block 3A electrical distribution section, then by another hour due to a fault LH2 thermostat. The launch vehicle performed successfully, but the payload failed to inject itself into orbit due to a guidance system failure.
