Building on its experience from the Scorpene submarine programme, the company has performed a value analysis to understand the individual worth of each equipment on board.This has allowed it to make informed judgements on the balance of performance versus cost.At 48.8m in length and displacing 855 tonnes surfaced, the double-hulled SMX-23 would be capable of remaining submerged for up to 60 hours at 4 knots. Operated by a crew of 19 (with space for an additional two trainees), it would have a mission endurance of up to 15 days.According to DCN, SMX-23 “is designed for precise navigation in shallow waters, with the ability to conduct surveillance while ‘bottomed’ on the sea floor”. It would also be “ideally suited for special forces missions [a lockin/ lock-out trunk for special forces is housed in the fin], intelligence gathering and minelaying”.Heavyweight torpedoes and/or anti-ship missiles could be carried in six torpedo tubes forward. There is no provision for reloads as an additional weapon stowage compartment would have required a significant increase in hull volume.The baseline combat system produced by DCN as part of its SMX-23 study comprises a fourconsole sensor, weapon and command system, a multi-array integrated sonar system, and an above-water sensor suite comprising a primary optronic mast, electronic support measures (ESM) and a navigation radar. A secondary optronic sensor would be fitted on the ESMmast._________________________a quick list9 U-21410+ SMX-234 Nuclear power suba nice looking PN force.
