HMAS Tasman Sea (CV-1940)


Back to Ship Index


The Australis Navy decided during the 1930's that 3 different types of Aircraft carrier were required for general service needs. 1, an attack carrier as large and carrying as many aircraft as possible (Endeavour class), 2, A medium sized carrier to operate with the Battlefleet carrying less attack aircraft and more defensive fighters (Tasman Sea class), 3, a carrier for escorting merchant ships either in convoy, as the fleet support ships or the attack transports carrying invasion troops (Albatross class).

This meant that each seperate type could be designed to perform that duty rather than the 'multi-role' vessels that other navies were building. Speed, armament, aircraft capacity, armour, range, all tailored to what the ship was to do.


The Tasman Sea class were to be built to act with the battlefleet. With the battleships making 25-28 knots an acceptable speed was deemed to be 26 knots. The bigger faster battleships and battlecruisers would act with the Endeavour class attack carriers. The ship was to be larger than the Van Diemen, which filled the same duty, and carry more aircraft. Longer range was required. Heavy ant-aircraft armament was also deemed neccessary.


The first of the class was laid down in 1936 (HMAS Tasman Sea - 1940) with another in 1937 (HMAS Foveaux Strait - 1940), then a further 2 in 1939 (HMAS Bass Strait, HMAS Timor Sea - 1942). The Emergency War building program added a further 2 in 1940 (HMAS Coral Sea, HMAS Arafura Sea - 1943) and 1941 (HMAS Lake Eyre, HMAS Lake Wanaka - 1944), and another 1 in 1942 (HMAS Solomon Sea - 1945) and 1943 (Spencer Gulf - 1946).  These were the last large ships laid down for the Australis Navy in World War 2 as building prioritised on the small AA cruisers, destroyers and escorts.
