HC Deb 04 April 1940 vol 359 c339W
Mr. Leslie Boyce

asked the First Lord of the Admiralty whether he will consider supplying blast-and splinter-proof shelters to trawlers and minesweepers for the protection of their crews when exposed to attacks from enemy aircraft while operating in the North Sea?

Captain Hudson

An order has been issued which requires owners of all British registered Vessels to provide protection for exposed personnel against machine-gun fire. Such protection will also be adequate against blast and splinters. Similar protection is being provided on minesweepers.
