Crusader (AV2767) was an Australian Army amphibious operations support ship of World War II. She was launched shortly before the war ended and entered service in late 1945. The Army did not need a ship with her capabilities after the war and she was sold in 1947 to the Queensland Cement and Lime Company which operated her on the Brisbane River until 1984. The ship was sunk in 1986 and later became a dive wreck.

Service history

Crusader was designed by the Australian Army's chief engineer Major General Clive Steele to support amphibious operations and carry supplies to Army units operating on islands in the Pacific. Steele deliberately underestimated the cost of building the ship in order to gain approval for her design and construction.[3]

Crusader's design incorporated a number of unusual features. The ship had a shallow draft to allow it to operate close to the shore and four rudders and six engines driving six propellers to give her a high degree of maneuverability. Crusader's hold could carry 1,500 tons of stores and an additional 40 vehicles could be embarked on her deck. The ship had six 30-ton cranes to move heavy equipment and vehicles were embarked and disembarked via six bridge-like structures.[3] This equipment allowed her to discharge cargo at the rate of 90 tons at any one time.[4] Crusader had a 'box-like' appearance, and her design did not impress naval engineers.[5]

Crusader was built by the Melbourne Harbour Trust at Williamstown Dockyard in Williamstown, Victoria. She was the largest all-welded steel vessel to have been constructed in Australia at the time, and cost considerably more to build than Steele's deliberate under-estimate.[3] The ship was launched on 8 August 1945 after being named by Steele's wife and later became the largest ship to be commissioned by the Australian Army during World War II. Construction of a sister ship, to be called AV2768 Corsair, was also begun, but this ship was canceled when the war ended.[6]

The ship entered service with the Army's No. 2 Ordnance Craft Park in late 1945. In February 1946 Crusader sailed to Rabaul in New Britain and later Torokina, Bougainville.[3] During this and later voyages she proved successful in her intended role, and returned supplies and equipment from the islands to Australia.[7] By 1947 the Army no longer needed a ship with Crusader's capabilities, and she was sold to the Queensland Cement and Lime Company (QCL) and renamed Cementco.[3]

QCL used Cementco as a self-propelled coral barge. The ship was converted by moving the wheel-house from the aft superstructure to about 50 feet from the bow[4] and extensively modifying the cargo holds to carry up to 2,000 tons of coral. Cementco's stern was later extended so that all her crew had their own cabin.[8] After the conversion was completed in 1948 the ship carried coral dredged from Moreton Bay by a converted Landing Ship Tank (the former HMAS LST 3022) to QCL's cement factory at Darra in Brisbane.[9] Cementco was retired in 1984 when QCL moved its factory to Gladstone, and was laid up at Mary Street wharf while attempts were made to sell her. During this period she was renamed Crusader II to avoid confusion with a new ship named Cementco.[8] A buyer was not found, and in 1986 she was sunk at Flinders Reef off Cape Moreton and subsequently became a popular dive wreck.[3]
