A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarines by detonating in the water near the target and subjecting it to a destructive hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a
The Space Force continues to support NASA's human spaceflight missions with range support of Space Launch Delta 45 and tracks threats to the International Space Station and other crewed spacecraft. [92] [93] The Space Force and NASA partner on matters such as space domain awareness and planetary defense. [94]
The Space Force has no command echelon equivalent of the U.S. Air Force′s numbered air forces, [25] so the next command echelon below field commands is the delta, a single level of command which combines the wing and group command echelons found in the U.S. Air Force. [25]

Until depth-finding sonar became available (the first was the Royal Navy's Q attachment in 1943), there was a "dead period" during the final moments before a depth-charge attack began when contact with the target would be lost. U-boat commanders became adept at sharp course changes and direction speed at these moments to break contact and escape.
Deep underwater explosions are those where the crater is small in comparison with the depth of the explosion, [2] or nonexistent. The overall effect of an underwater explosion depends on depth, the size and nature of the explosive charge, and the presence, composition and distance of reflecting surfaces such as the seabed, surface, thermoclines ...
