Nikitin PSN-1

The Nikitin PSN-1 was a piloted glider anti-shipping missile produced in the USSR from 1937.

Development
From 1933 a series of special projects was initiated under the PSN banner (Planer Spetsial'no Naznachenaya - Glider for Special Purposes). A proposal was made by S.F. Valk for a glider anti-shipping bomb with Infra-Red guidance, which was expanded to include DPT (long-range glider torpedo), LTDD (Long-range flying torpedo) and BMP (towed mine glider). To evaluate the Kvant Infra-Red guidance a piloted version was produced as the Nikitin PSN-1. Nikitin and Mikhelson designed a small single-seat monoplane flying boat glider with floats at approx 1/2 span, carrying a torpedo underneath. The PSN-1 was carried aloft by either Tupolev TB-3 or Tupolev TB-7 motherships and released at the appropriate height.

At least 10 were built and many of these were flown during trials of the autopilot and the Kvant (Quantum) guidance system.
