 The TG-3A is a two-place, dual-control glider manufactured for the Army Air Forces by the Schweizer Aircraft Co. during WW II. It was derived from the Schweizer SGS 2-12 high-performance sailplane (designated XTG-3 by the AAF). The AAF evaluated the aircraft in 1942 for suitability as a trainer for cargo glider pilots. After testing three XTG-3s, the AAF ordered 110 TG-3As from Schweizer (50 more were ordered from Air Glider, Inc. but only one was built). Student glider pilots normally received about six hours dual instruction in the TG-3As before being trained in the large CG-4A cargo glider. 
The TG-3A's wings are made of spruce and mahogany plywood covered with doped fabric. It is equipped with spoilers (used to increase descent rate) as well as ailerons. The fuselage is constructed of welded chrome-molybdenum steel tubing which is fabric covered. The landing gear is a single unsprung wheel with a disc brake. In addition, there are skids on the nose, tail, and wing tips.
