Question

What were the propellers on the Project 705 Alfa submarine's after horizontal stabilizers for?

Short answer

They were auxiliary propulsors used to improve low-speed and harbor maneuvering.

Notes

The small propulsors assist low-speed maneuvering. Harbor use is recalled by a panelist drawing on what they were told through Finnish naval experience. The answer checks that recollection and identifies the devices as maneuvering aids.
