As usual, Wiki is WRONG.
From the diary of STAG-1, the unit that developed & used TDR-1s ...
"The first attack was conducted on 30 July 1944, on a derelict Japanese freighter, the YAMAZAKI MARU, that had grounded itself near Cape Esperance on Guadalcanal Island in the Solomons. Six TDR-1s, with four intended for the attack and two as backups, were committed to the attack, all armed with 2,000 lb bombs. Two crashed on takeoff, two performed attacks that were frustrated by dud bombs, but two went off with very impressive bangs. It made for great film footage, but by that time the program's standing was so low that they had to lobby very hard just to keep the program from being cancelled.
From 27 September 1944, STAG-1 conducted a series of attacks on Japanese installations on the island of Bougainville. When the attacks ended on 26 October 1944, STAG-1 had expended 46 TDR-1s in combat, with 37 performing attacks and at least 21 hitting their targets. The Japanese found the attacks startling, believing that the Americans had taken up suicide attacks."
