History

The Imperial Japanese Navy never put much effort into protecting their merchant ships from submarines prior to World War II. This is due to the IJN view of submarines in their doctrine, not as commerce raider but intended for direct combat. As a result, their first-line destroyers at the start of World War II weren't armed with depth charges at all. The Type 3 depth charge was introduced during the war to solve this issue.

Like other areas where Japan was deficient during this period, the design was copied from a foreign source. British depth charges were used as the basis for the Type 3 depth charge, which is also called the Type 2 due to being designed in 1942 but entered service in 1943. Originally using 230 pounds of Type 97 explosives (70% TNA/30% HNDA) and depth settings of 98, 197, 295, 394, or 476 feet, but later had 357 pounds of explosives. However, the IJN didn’t often use deeper settings. The Type 3 and similar depth charge designs were used on destroyers, but it was also used on dedicated escort ships that could carry up to 120 depth charges.
