The
mention of Able Seaman Benningfield as Range Taker is particularly
significant. The V&W WAIR destroyers were not fitted with fire
control radar until 1942, and while the two twin 4 inch mountings were
director controlled, the range of the target had to be measured by an
optical range finder. The range was required not just to determine the
elevation of the guns, but to set the time on the fuses of the shells
so that they would burst in the vicinity of the aircraft.
