David K. Brown, a senior British warship designer and for many years a major historian of British naval design, died on 16 April. Brown was personally responsible for the preliminary design of the Tribal-class frigates (Type 81) of the 1950s and for the full design of the Castle-class offshore patrol vessels, which he was proud could operate helicopters under much worse conditions than other ships of their size. He was chief of preliminary design in the late 1970s, when the Royal Navy considered but rejected more powerful destroyers (Types 43 and 44) and when he suggested an inexpensive carrier, which may have helped inspire HMS Ocean.
