As I understand it, the Mir Base Block had an Igla docking system at the aft docking port where Kvant-1 docked. I know it docked to this port using an Igla... somewhat problematically.

However, was the aft port originally equipped with an Igla, Kurs, or both? I know the manned Soyuz TM-3 docked with Kvant-1 not long after it was attached to Mir, which would lead me to believe it had a Kurs system from the beginning. However, a large number of Progress 7K-TG ferrys also docked there which were originally equipped with an Igla and I haven't found any sources that say the 7K-TG were upgraded with Kurs.

I also know that in 1991, EVAs were performed to replace/repair a damaged Kurs antenna on Kvant-1, so it had one by then.

Rear port features Igla and Kursrendezvous and docking systems. Front port features Igla only; it was used for initial docking with the rear port of the Mir baseblock. After docking in 1987, the front port Kvant antenna wasfolded down, its work done.
