1985-062A
11F615A15 No. 126 (7K-TG No. 126, Progress No. 126) was launched on 1985 Jul 19. On the first orbit, telemetry erroneously indicated the Igla antenna had not deployed, precluding a docking. The satellite was announced not as Progress-25 but instead as Kosmos-1669. However, it later was found that the antenna deployed correctly, and the craft docked with Salyut-7 successfully. It was the last Progress launched to Salyut-7. There may have been a re-rendezvous test after undocking.
