:D Confirmation that "Special Hull" C-36204 was ordered by BuShips (CAPT Hyman G. Rickover) for test by BuOrd in association with Project Stinger. Hull was to used for live scuttling/detonation tests, but looks like the project was halted before this ordnance test took place. PT "Drones" were to carry 17 tons of TNT within the Steel cribbing. A group of twelve PT "Drone" boats were to be used to lay both bouy markers and to clear a channel through harbor defensive mine fields (first scuttled then charge detonation). They would then be followed by three DEs "Drones" with 1200 tons of TNT to widen the channel for the follow on AK (ammo ship) "Drone" loaded with 8000 tons of TNT. The AK would destroy the harbor, much like in Bergen and Bombay and Halifax. Then a DE with Napalm and other pyrotechnics ordnance would be sent in and detonated to set the remaining Harbor defenses on fire. Pretty vicious way to neutralize a harbor.

By the end of the project in December 44, only 10 PT Boat kits were ordered (photos of C-36204, Elco hull 3683 were used for the instruction manuals). PT-140 was the "Drone" test PT Boat used during the Summer and Fall of 44, and the 70' experimental Higgins "Hellcat", PT-564 was used as a control boat. This accounts for the "2" PTs mentioned as part of the project. A PV-1 Ventura was also tested as a control aircraft. There was a request for two of the Hacker boats from Campbell. Not sure of how they were used, but there is definitely a pretty good tie-in with the OSS project (several of the same officers).

From the RG-38 records at NARA. Thank you Mil-tech Bard!
