Ship project history: Design of "O" class submarines was developed on the basis of "L" class boats. New ships intended for service in the Far East and so they required increased endurance and improved seaworthiness in comparison with prototype. Lead Oberon had saddle-tank construction and was built under the 1923 program, operational diving depth was 60 m, maximal was 155 m. Oil fuel tanks were out of a pressure hull and were leaked at big depth. It was possible to be saved of this lack during repair, when riveted tanks were been replaced by welded (also fuel stowage has increased to 186t). Designed speed was 15/9kts, but it has not been even reached. Oberon became the first British submarine with sonar provided even at designing. Almost simultaneously with Oberon the order for two submarines was given out by the Australian government. Design of these boats was developed by firm Vickers-Armstrong, and they favourably differed from Admiralty designed Oberon. At the expense of minor alteration of hull lines and form of fore end Australian submarines have reached designed velocity.

6 more units have built under the 1926 program (3rd group), their design has been developed on the basis of the Australian ships. A little increased dimensions and usage of more powerful diesels allowed to increase surface speed. Besides, an operational diving depth have increased to 95m. Stern TT had no spare torpedoes.
