Flutto-class Submarine

	Flutto-class Submarine The ''Flutto'' class were a large class of submarines built for the Italian Royal Navy (''Regia Marina'') during the Second World War. The ''Flutto''s were a development of the 600 Series of medium-sized, or seagoing, submarines. They were built to a partial double-hulled Bernardis design, influenced by war-time experience and construction adapted for mass construction. The ''Flutto''s were good sea-boats with improved internal arrangements, hull strength, anti-aircraft armament and diving times. They are regarded as the best medium-displacement submarines built by Italy up to that time. A total of 48 submarines were ordered, in three series (referred to as "Types"). The name ''Flutto'' means “wave”, and the Type I vessels were named for marine terms and sea-creatures. The Type II and Type III vessels all bore names of metals. Type I The first series of 12 vessels were laid down in 1941; six from CRDA, and three each from OTO and Tosi. Of these 10 were commissioned and ...

picture info	HMCS Port Arthur HMCS ''Port Arthur'' was a Royal Canadian Navy revised which took part in convoy escort duties during the Second World War. She fought primarily in the Battle of the Atlantic. She was named for Port Arthur, Ontario. Background Flower-class corvettes like ''Port Arthur'' serving with the Royal Canadian Navy during the Second World War were different from earlier and more traditional sail-driven corvettes. The "corvette" designation was created by the French as a class of small warships; the Royal Navy borrowed the term for a period but discontinued its use in 1877. During the hurried preparations for war in the late 1930s, Winston Churchill reactivated the corvette class, needing a name for smaller ships used in an escort capacity, in this case based on a whaling ship design. The generic name "flower" was used to designate the class of these ships, which – in the Royal Navy – were named after flowering plants. Corvettes commissioned by the Royal Canadian Navy during the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
