HMS D4 was a British D class submarine built by Vickers, Barrow. D4 was laid down on 24 February 1910, launched 27 April 1911 and was commissioned on 29 November 1911. She was the first submarine to be fitted with a gun for offensive use.
During D4's career, she sank the grounded the German netlayer Bielefeld in the Heligoland Bight, on 15 June 1915.
Later in her career, D4 torpedoed UB-72 on 12 May 1918. At 04:30 that day, whilst on patrol approximately midway between Guernsey and Portland Bill, D4 observed UB72 on the surface travelling in a southerly direction some two miles distant. Five minutes later Lt Claud Barry in command of D4 saw UB72, obviously unaware of the British boat's presence, alter course so that the U-boat appeared to be approaching D4. In order that his presence should not be detected Lt Barry lowered his periscope for a few minutes but at 0443 D4's periscope was raised to reveal UB72 steering an easterly course. A few minutes later UB72 was on the British boat's port side and Barry waited until the U-boat came on to his sights. At 0450 Lt Barry fired a torpedo 600 yards from target and after lowering periscope for a few moments he released a second one. Ten seconds later the crew of D4 heard an explosion and felt a violent concussion. Barry brought his boat to the surface and headed towards three men swimming in a patch of oil. He succeeded in picking up these men, who were the only survivors of UB72's crew of three officers and thirty-one men.[3][4]
D4 was decommissioned in 1919 and was then sold on 17 December 1921 to H Pounds, Portsmouth.
