Description
This booster is used with the old Mk series chemical shell for 155mm guns and howitzers. It is commonly called an adapter burster because its function is to burst the shell body and release the chemical filler. The Mk VIB consists of an adapter and exterior booster casing made in one piece, an interior booster casing and a fuze socket. The exterior booster casing is threaded externally with tapered pipe threads to form a gas tight seal when screwed into the nose of the projectile. This outside booster contains the main booster charge of 9 ounces of TNT. The main charge is detonated by the interior booster which fits inside the main charge and contains 1 ounce of tetryl. The fuze socket fits into the adapter and extends into the inner booster. It seats the M46 Fuze. The adapter booster is protected against injury to the threads and the entrance of foreign substances by an adapter plug.
