Lockheed Yo-3a

Manufacturer: LOCKHEED

The Lockheed YO-3A Quiet Star was a single‑engine, low‑wing observation aircraft developed for the U.S. Army during the Vietnam War. Built on a Schweizer SGS 2‑32 glider airframe, it was engineered to be acoustically silent so that it could fly at low altitudes at night without being detected by enemy forces.
