Interwar Period
Between the wars, navies experimented with submarine cruisers (France, Surcouf), submarines armed with battleship calibre guns (UK, HMS M1) and submarines capable of carrying small aircraft for reconnaissance (HMS M2 and the Surcouf).
Germany was denied submarines by the terms of the Treaty of Versailles and secret production was not legitimized until the Anglo-German Naval Agreement of 1935 under which the UK accepted German parity in submarine numbers with the Royal Navy.

Famous quotes containing the word period:
“Not only do our wives need support, but our children need our deep involvement in their lives. If this period [the early years] of primitive needs and primitive caretaking passes without us, it is lost forever. We can be involved in other ways, but never again on this profoundly intimate level.”
—Augustus Y. Napier (20th century)
