Development[]
The Mark VII depth charge most likely has its roots in British depth charges developed and used during World War I.[1]
Service[]
The Mark VII depth charge was the primary British anti-submarine weapon until 1944 when the anti-submarine projectile launchers the Hedgehog spigot mortar and Squid three-barrelled mortar introduced in 1943 and 1944 proved more effective.[1] In 1939 this was the only anti-submarine weapon available to British surface ships.[1]
Variants[]
- Mark VII heavy
- Introduced in 1940. A 150 lb (68 kg) cast iron weight was attached to increase sinking rate. [1]
- Mark VII Airborne depth charge
- Introduced in 1941, this was the Mark VII depth charge adapted for use from aircraft. Had nose and tail fairings that broke off when it hit the water. [1]
