On January 31, 1946, the United States Army Air Service promulgated a requirement for two new assault gliders, a light glider capable of hauling 8,000 lb (3,628.7 kg) of military equipment within a 24 ft (7.3 m) long cargo space, and a heavy glider capable of hauling 16,000 lb (7,257.5 kg) of military equipment within 30 ft (9.1 m) long cargo space. Chase and Douglas were awarded contracts to build 'light glider' prototypes, with the Chase design being designated XCG-18 and the Douglas Model 1028 receiving the XCG-19 designation.[N 1] The Model 1028/CG-19 utilized aluminum for the construction of the fuselage, and its cargo compartment was 24.7 ft × 7.7 ft × 6.5 ft (7.5 m × 2.3 m × 2.0 m); for loading cargo, the CG-19's rear fuselage was hinged to swing sideways. A mockup of the CG-19 was inspected in March 1947, but when the US Air Force was facing tight budget constraints with respect to the CG-18 and CG-19 designs, it decided to cancel the CG-19 because the CG-18 was nearing completion.[2][3]
