What type of weapon is the Mk 11 Mod 3?

The Mk 11 Mod 3 is classified as an anti-submarine depth charge. Depth charges are explosive weapons designed to be dropped into the water to detonate at a certain depth, targeting submarines that operate below the surface. This particular model is part of a family of anti-submarine weapons used to increase the effectiveness of naval forces in engaging underwater threats. The design and deployment of depth charges aim to damage or destroy enemy submarines, making them a critical component of anti-submarine warfare.

Other options, while they may refer to different types of military ordnance, do not accurately describe the Mk 11 Mod 3. For instance, anti-tank mines are designed to explode upon contact with a tank or armored vehicle, while an anti-aircraft torpedo would be intended for targeting airborne threats but does not align with the role of depth charges. Fragmentation grenades, on the other hand, are handheld explosive devices used primarily in infantry combat rather than naval operations.
