The Navy Frogmen – Underwater Demolition Teams

Made in 1957, this amazing U.S. Navy film showcases the pre-cursors to the SEALs and the UDTs (or Underwater Demolition Teams). Underwater Demolition Teams (UDT) conducted beach reconnaissance, cable and net cutting, explosive destruction of underwater obstacles for amphibious landings, limpet mine attacks, submarine operations, and the locating and marking of mines for minesweepers. They also conducted river surveys and foreign military training. While doing this, the UDTs pioneered combat swimming, closed-circuit diving, underwater demolitions, and midget submarine (dry and wet submersible) operations. Many of these capabilities are shown in this film, which likely inspired Hollywood to create “Sea Hunt” and might have been fodder for Ian Fleming as well. An especially interesting segment shows UDTs deploying from a submerged GUPPY-class submarine, a strategy they famously employed during the Korean War to raid enemy railways.

It is amazing how far we have come since 1957. The technology we use for underwater welding has gotten much better as well as our diving equipment. It must have been very dangerous for these men to complete an underwater welding job with this kind of equipment. It is dangerous enough as it is today.
