XM147 "Super DUKW" Amphibious Truck
The XM147 "Super DUKW" was an amphibious vehicle that evolved from the Truck, Amphibious, 2 1/2 ton, 6x6 DUKW. Several experimental versions of the 4-ton 6x6 Super DUKW were built for the U.S. Army and tested at Aberdeen Proving Ground from circa 1953 to 1957. Super DUKW was designed for the same purpose as the original DUKW, for moving cargo from ship to shore in support of over-the-beach invasions with no harbor facilities.
Just as the original DUKW was based on the GMC WWII CCKW 2 1/2-ton truck, the Super DUKW was based upon the post-WW II M135 series GMC trucks, using their engine and automatic transmission mated to a 5700-pound combined hull-frame structure (weight based on the XM147E2). The prototype XM-147 Super DUKW began testing in 1953. While never standardized, a small number of XM147 Super DUKWs remained in service for several decades and a few survived to be restored by collectors. The XM147 project was eventually cancelled, replaced by the LARC-V (Lighter, Amphibious, Resupply, Cargo, 5 ton capacity).
