A standardized national type for the transport of airborne units, such as the Ju-52 in Germany, has not yet been revealed in enemy operations in the Orient. In some raids, the Japanese have used type TB-92 four-motored bombers. In the Palembang attack, among the craft they used were several captured Hudsons with British identifications; at Koepang, aircraft resembling Douglas types were used. Japanese parachutists are known to have been transported in command planes, such as the Kawa amphibian biplane, Model 115; in transport planes, such as the triple-engined Mitsubishi, Model 112, bomber and transport; and in various pursuit planes. It was reported a year ago that the Fukudakei factory was producing troop-carrying gliders with 25-horsepower engines to extend the range.
