Description
The head is of solid steel and contains no high explosive or fuze. The shape of the round gives a relatively long underwater travel at shallow depth-of-entry angles (about 20 degrees), and it is used as a semi-armor-piercing projectile against submarines or tanks. The Mk 1 was the California Institute of Technology production which was adopted by Bureau of Ordnance and designated the Mk 2.
