The McDonnell TD2D Katydid was an American target drone produced by McDonnell Aircraft that began development in 1942. ==History== The U. S. Navy awarded McDonnell Aircraft a contract for a radio-controlled target drone in 1942 under the designation of XTD2D-1 for anti-aircraft and aerial gunnery practice. Production models, built in unknown quantity, used the designation of TD2D-1. The Navy changed its designation system in 1946 and the XTD2D-1 and TD2D-1 were redesignated as XKDD-1 and KDD-1, respectively. Later that year, the Navy changed McDonnell's manufacturer code letter from "D" to "H", and the KDD-1 was redesignated again as KDH-1.
