Paul Wild became one of the young radar officers who ensured the Royal Navy used its new technology to maximum effect. In July 1943, commissioned as a Probationary Temporary Acting Sub-lieutenant (Special Branch, Royal Navy Volunteer Reserve), he started an intensive, six-month radar officer training course at the Royal Navy base, Portsmouth. His seagoing appointment for the following two and a half years, with 60 subordinates and 24 radar sets, was the battleship , which eventually became flagship of the British Pacific Fleet. The ship took part in the Okinawa campaign, followed by the assault on the Japanese mainland. In both campaigns the fleet was frequently attacked by Japanese suicide bombers, but because they tended to concentrate on aircraft carriers, his ship was not hit. The battleship entered Tokyo Bay just after the surrender of Japan and he was present when the peace treaty was signed.
