(a) Patrick Blackett, Baron Blackett http://en.wikipedia.org/wiki/Patrick_Blackett,_Baron_Blackett
(1897-1974; an English experimental physicist; In 1948 he was awarded the Nobel Prize in Physics, for his investigation of cosmic rays using his invention of the counter-controlled cloud chamber)
(b) U-Boat http://en.wikipedia.org/wiki/U-Boat
(U-boat is the anglicized version of the German word U-Boot, a shortening of Unterseeboot, which means "undersea boat")
(c) depth charge http://en.wikipedia.org/wiki/Depth_charge
(now largely been replaced by anti-submarine homing torpedoes; The first effective depth charge, the Type D, became available in January 1916 [developed by UK])
(d) Radar http://en.wikipedia.org/wiki/Radar
(The term RADAR was coined in 1940 by the United States Navy as an acronym for RAdio Detection And Ranging; Before the Second World War, researchers in France, Germany, Italy, Japan, the Netherlands, the Soviet Union, the United Kingdom, and the United States, independently and in great secrecy, developed technologies that led to the modern version of radar)
