U28580205: "Advanced Torpedo" is a vague term; please clarify. Added in some P&C base on in-game stats. Removed historical-game discrepancy, those should be reported on the Bug Reports on the forums.

 == History ==
-The Mark 20 Bidder was designed around the 1950s. It was intended to become the designated torpedo for both new submarines and surface ships. The Mark 20S was intended to equip the submarines, while the Mark 20E was to be used on surface ships. Both types of torpedoes was passive-seeking battery powered. However, the Mark 20S was smaller than the Mark 20E. The S had a single-speed setting at 20 knots, while the E had a dual-speed mode for target search and attack. The velocity of the E was, respectively, 15 knots and 24 knots. At 15 knots the torpedo had a range of 18000 m, while when running in attack mode at 24 knots it had a range of 5500 m.

-The torpedo was to be equipped on the Rothesay and Whitby ([[HMS Blackpool]]) class frigates, and some of these ships had torpedo tubes fitted and was ready to receive them. However, due to problems with the programming of the torpedo, the weapon was never fitted nor used by any of these classes. Some years after, the Mark 20E was proposed for the Leander class destroyers, but that consideration was eliminated in the 1960s.
