HMAS Oceania (BB-1945)


Back to Ship Index


Ever since I found the "Japanese-batttship_forces_p1_by_kara_alvama-d3jrlv3" drawings I have wanted to use the hull of one of them for a battleship class. What I found difficuilt was who in my AU's could afford to build a battleship of the size this ship would be. I decided that an extra large gold strike somewhere around Kalgoorlie and owned by the Government could pay for it. In the last Westralis class battleships I actually reduced the class of four down to 2 because of the war. For the Oceania to be completed in 1945 then the ship would have to be laid down in 1939-40. The only reason for the ship is if the details of the Yamato and then the Montanas as the CUA reply reached the Commonwealth designers and the Oceania was their reply. (Anyway everybody loves the big ones.)

With a large amount of sheer forward for better handling characteristics and speed, the Oceania was a sleek looking ship. Like the Montana class the Oceania was to be armed with four triple 16" turrets. While this may not have quite matched the 18" of the Yamato, the faster firing and more barrels of the 12x16" armament allied with the types of gunnery and ranging radar available by 1944-45, the Oceania would have shot the Yamato to bits. The large number of 5.25" and 40mm guns (and no 20mm at all) showed where the greatest danger to the ship was expected to come from. The lack of 20mm guns stemmed by the need for greater knock-down power required to splash the Japanese Kamikazes. The 40mm guns were controlled with radar predictors that made the guns much more accurate and then with the proximity fuse they became even more lethal.

A huge propulsion system was installed to power the ship through to the required speed of 32 knots. The large strake of main armoured belt covered all of the main armament and magazine areas for the length of the ship. A heavy quantity of deck armour was installed.

Notes HMAS Oceania (02/1945)


HMAS Oceania ready to leave for its first war cruise in June 1945.

The aft part of the hull and the aircraft handling facilities were designed to stop the blast of the 16" guns firing astern from warping the catapults and cranes.
