Did the Allies use submarines

Answer 1

I assume you mean World War I, when the U-boats were the scourge of the seas. Yes the Allied nations had subs, in part to counter the threat of German submarine actions. A popular tactical idea of the time , espoused by the (battleship admirals) was the idea of Fleet Submarines with a high surface speed which could operate with the fleet, say with a major task force of surface ships-rather than an independent subamrine arm operating alone, as most did, or in organized (Wolf Packs) which would attack convoys of transports, etc. The pro suface fleet men espoused the Fleet Submarine concept- The RN had several (British_) some as hot on the surface as a destroyer (they were steam-electric with special retractile stacks) and odedly Czarist Russia had the elite A-9 class. the a-9"s were medium sized subs with good sea-keeping characteristics-in line with the fleet sub role- They had steam-e;lectric drive(naptha or alcohol burning boilers for the steam turbines) and a high surface speed, according to sub expert Norman Polmar War I A-9 class could do 26 Knots on the surface, a good rate of speed for a surface craft!. up to 23 knots at (Siphon depth) on the main engines- the Russians used the siphons to keep them running up to , well siphon depth, and recharge the batteries, on pure battery power they could go deep, at least l50 metres or so, but- could only manage 5 knots -Running on the batteries was thus, a tactic to avoid. so went the Russian fleet subs of War i- A-9 might have been codenamed- and the use is appropriate(can be used in command form to mean (Resurface!)- The Anastasia! Czarist sub, right comrades? Anastasia has nine letters and begins and ends with a. a good code cipher, and- appropriate in meaning- May she rise again! we wuld wan t s sub called(Bottom feeder or Catfish?)
