However, Japanese destroyer design, tactics, training, and doctrine emphasized surface nightfighting and torpedo delivery (necessary for fleet operations) over anti-submarine duties. By the time Japan finally developed a destroyer escort , which was more economical and better suited to convoy protection, it was too late; coupled to incompetent ...

The ACTUV is aimed at improving the ability to detect and engage diesel-electric submarines, which are inexpensive and quieter in comparison to nuclear-powered submarines, and to negate the threat of adversaries building large numbers by creating anti-submarine tactics at one-tenth the cost of building a diesel submarine.

The success of pack tactics ...
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 specific depth from the surface.
