A U.S. Navy Interstate TDR-1 assault drone being prepared for an attack. During September and October 1944, Special Task Air Group One (STAG-1) operated TDR-1s from Banika, Russell Islands, in combat action against enemy targets in the Solomons area. During a two-month period, 50 drones were launched with 31 hits recorded on anti-aircraft sites, bridges, airfields and grounded ships. Guided by a modified Grumman TBM-1C Avenger torpedo bomber, the drone would be launched by a ground control crew, and then turned over to the TBM pilot already airborne over the field. Joined on the drone, the TBM pilot would pass control to the controller in the rear cockpit, who would then guide the drone to the target, his 12.5 cm (5-inch) TV screen receiving visual signals from the TDR's nose-mounted camera. By October 1944, the use of the TDRs ended, the concept of precision-guided munitions deemed of lesser priority in the Pacific due to U.S. air superiority.
