Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, duri ...

Type 79 100 Mm Naval Gun
The Type 79 Twin 100 mm gun is the first indigenously developed large caliber Chinese naval gun. A decision was made in 1970 to replace the Soviet 100/56 B-34 single 100 mm semi-enclosed gun mount. By June 1973, the first batch was completed and two were installed onboard frigates for test and evaluation. Two more upgrades were eventually developed. Type 79 The first of the family, this gun was fully automatic and controlled by Type 343 radar. However, being the first fully automatic gun and the first indigenously developed gun at the same time, the Chinese was not confident enough on the design, and thus incorporated manual backup systems. This proved to be baseless because later operation proved that the reliability of the automated system was just as good as the simpler manual system. Type 79A (H/PJ33A) Based on the successful performance of the automated system, the manual backup system was eliminated in this upgrade. As a result, the total weight and size ...
