HMSJ5 (laterHMASJ5) was aFirst World WarJ-classsubmarine operated by theRoyal Navy and theRoyal Australian Navy.
The J class was designed by the Royal Navy in response to reported German submarines with surface speeds over 18 knots (33 km/h; 21 mph).[1] They had a displacement of 1,210 tons surfaced, and 1,820 tons submerged.[1] Each submarine was 275 feet (84 m) in length overall, with a beam of 22 feet (6.7 m), and a draught of 14 feet (4.3 m).[1] The propulsion system was built around three propeller shafts; the J-class were the only triple-screwed submarines ever built by the British.[1] Propulsion came from three 12-cylinder diesel motors when on the surface, and electric motors when submerged.[1] Top speed was 19 knots (35 km/h; 22 mph) on the surface (the fastest submarines in the world at the time of construction), and 9.5 knots (17.6 km/h; 10.9 mph) underwater.[1] Range was 4,000 nautical miles (7,400 km; 4,600 mi) at 12 knots (22 km/h; 14 mph).[1]
Armament consisted of six18 inch (450 mm) torpedo tubes (four forward, one on each beam), plus a 4-inch deck gun.[1] Originally, the gun was mounted on abreastwork fitted forward of the conning tower, but the breastwork was later extended to the bow and merged into the hull for streamlining, and the gun was relocated to a platform fitted to the front of theconning tower.[1] 44 personnel were aboard.[1]
J5 was built for theRoyal Navy by HM Dockyard atDevonport inPlymouth.[2]J5 was launched on 9 September 1915 and commissioned on 6 May 1916.[citation needed]
She and the other Js were members of the 11th Submarine Flotilla. She served in theNorth Sea chiefly in operations against German destroyers andU-boats, most of encounters were with the latter. Although engaging several times with enemies, the closest she got to sinking the enemy was strikingU-86 with a torpedo which did not explode.
After the war, theBritish Admiralty decided that the best way to protect the Pacific region was with a force of submarines and cruisers.[1] To this end, they offered the six surviving submarines of the J-class to theRoyal Australian Navy as gifts.[1]J1 and her sisters were commissioned into the RAN in April 1919, and sailed for Australia on 9 April, in the company of the cruisersSydney andBrisbane, and the tenderPlatypus.[1]J5 broke down while traversing the Red Sea, and had to be towed the rest of the way byBrisbane.[1] The flotilla reached Thursday Island on 29 June, and Sydney on 10 July.[1] Because of the submarines' condition after the long voyage, they were immediately taken out of service for refits.[1]
Apart from local exercises and a 1921 visit to Tasmania, the submarines saw little use, and by June 1922, the cost of maintaining the boats and deteriorating economic conditions saw the six submarines decommissioned and marked for disposal.[1]
J5 was paid off on 12 July 1922. She was sold on 26 February 1924 and after stripping, she,J1, andJ2 were scuttled in theship graveyard offPort Phillip Heads on 4 June 1926. The wreck ofJ5 lies in 39 metres (128 ft) of water at38°09′S144°52′E / 38.150°S 144.867°E /-38.150; 144.867 and can be accessed by experienced divers.[3]
