https://peertube.dngr.us/videos/watch/5cc1a5e4-d6f1-4667-b5b0-3b32317c120b RIG FOR ULTRA QUIET presents an overview of submarine warfare in WWII, and shows post-WWII submarine warfare activities. It especially focuses on early nuclear-capable guided missile submarine capabilities. The Soviet threat, then brought to the world's attention through the suppression of the Hungarian Revolution, is emphasized. Guppy type subs, including two Regulus guided missile boats USS Tunny and USS Barbero, along with nuclear submarines are shown undertaking a simulated Atlantic war sortie. At the 10:30 mark, as part of the war game, the Regulus submarines are shown making a retaliatory strike on Soviet bases. The Regulus submarines were a stop-gap measure, soon replaced by the underwater-launched Polaris submarines. The Regulus missile carried one of the largest warheads of its era, and its story is well documented in the documentary "Regulus: The First Nuclear Missile Submarines" available on Amazon.com The SSM-N-8A Regulus was a ship- and submarine-launched, nuclear-armed turbojet-powered cruise missile deployed by the United States Navy from 1955 to 1964. Its barrel-shaped fuselage resembled that of numerous fighter aircraft designs of the era, but without a cockpit. When the missile was ready for launch, it was fitted with two large booster rockets on the aft end of the fuselage. The film ends with images of submarines firing torpedoes against enemy ships and submarines. Motion picture films don't last forever; many have already been lost or destroyed.
