(A.S.03835/40. – 27.2.1941.)

Owing to increasing requirements and wide distribution of stocks of fuzes, time, No. 206, difficulty may be experienced locally in meeting urgent demands for replenishments for this fuze if large expenditure takes place on any particular station.

     2.  The question of supplying fuzes, No. 401, Mark II, in lieu of fuzes, No, 206, has therefore been considered, and the following is a list of H.M. ships to which the fuze, No. 401, Mark II, could be issued if the necessity arises for use with full charges, without any modification to fire control arrangements being required, viz.:-

Ships with Bulkhead Fuze
Transmission Units





Eastney A.A. Battery.











“Queen Elizabeth.”

R.A.N. “G” School.
“Royal Sovereign.”




Ships with Fuze-keeping Clocks

“Black Swan” class sloops.
“Egret” class sloops.
“Grimsby” class sloops.
