Johan Visschedijk: "The US Army development of troop-carrying gliders began in 1941, with experimental contracts for a series of prototypes to meet two separate specifications. The first requirement was for an eight to nine seat transport, and contracts were placed for single prototypes of the Frankfort Model TCC-41 as the XCG-1 (s/n 41-29615); the Waco NYQ-3 as XCG-3 (41-29617); the St. Louis XCG-5 (41-29619) and the Bowlus XCG-7 (41-29621).

The second type was to be a larger, fifteen-seat glider, and the same four companies each received contracts for a single prototype: Frankfort TCC-21 as XCG-2 (41-29616); Waco XCG-4 (41-29618); St. Louis XCG-6 (41-29620) and the Bowlus XCG-8 (41-29622).
Of the eight prototypes ordered, all but the XCG-1, XCG-2 and XCG-6 were completed and test-flown but no further development of the St. Louis or Bowlus designs occurred, only the two Waco types reaching quantity production. The CG-3A, which was used principally for training, while the CG-4 became the first and most-widely used US troop glider of WW II. The CG-4as were towed into the war-theaters by C-46s and C-47s. In British military service it was named Hadrian.
After trials with the XCG-4 in 1942, a second prototype was ordered (42-53534) and plans were made for large scale production in which, eventually, sixteen US companies received orders for the CG-4A and delivered a total of 13,906 examples.
