The field of anti-submarine warfare was first truly developed during World War I when German U-boats turned the submarine into a truly practical piece of naval operations. The United States made its first depth charges from a design originating in the UK and during World War II, the two nations would continue cooperation in making new ASW weapons. The United States Navy adopted the British [[Mk.10 Hedgehog mortar]] designed in late 1942 as their first forward-firing ASW weapon. The Hedgehog was more effective than conventional depth charges as it only detonated when it hit the enemy submarine which allowed for more damage and reduced disruption to the sonar tracking.

While the Hedgehog was an effective design, it was too large for mounting on smaller ships in the US Navy such as corvettes or frigates. In response, the '''Mark 20 Mousetrap''' was created to be a similar weapon that could launch anti-submarine explosives off the deck of a US Navy ship. A problem with the spigot mortar system used by the Hedgehog was it places considerable stress on the deck when fired so they used launch rails instead that launched the projectiles. Unlike the Hedgehog, the Mousetrap uses rockets that burned for .2 to .7 seconds to launch the explosive into the water. The launchers originally used 85-pound projectiles before the decision was made to use the lighter 65-pound projectiles shared in the Hedgehog. The 7.2-inch rockets carried 31 pounds of TNT or Torpex (42% RDX 40% TNT and 18% powdered aluminum) warheads which added 1.5 pounds to the weight. It was not as effective as the Hedgehog due to the fact it fired at a fixed 48-degree elevation and couldn't compensate for rolling. However, it filled the vital niche of arming smaller ASW ships such as [[SC-497]] and [[PC-451]].

The '''7.2-inch T37''' Demolition Rocket is an explosive rocket developed from the projectiles used by the Mousetrap. It used a standard 2.25-inch rocket motor and a 32-pound C2 explosive warhead. Intended for use against concrete bunkers, the T37 was first designed by Caltech before the design was given to the US Navy in July 1944. The rockets first saw combat in August during Operation Dragoon, the landings in Provence, Southern France. The rockets were used for coastal barrages from Landing Craft Rocket craft in 120-round "Woofus" mounts. The rockets were later on tanks in the T40 "Whiz Bang" 20-round that fired a full barrage of rockets in 10 seconds. The other mount was a 24-round "Grand Slam" mount also for tanks. Despite the extra destructive power, the tank mounts were not popular because they blocked the turret hatches.
