How are Norden submarines so stealthy?
By being extremely slow when using their AIP, it's good enough for coastal defence but would be useless for long range power projection which is why they can't get any sales with countries that deploy globaly.
>>64759169>extremely slowCurrent 212a can go for 8 knots on AIP. not fast, but not that slow.next gen 212nfs/212cd will be equipped with pic related, a single module can put out 80kW, you can easily stack multiple of them into a 1-2 MW AIP system, that would give the boat a speed of 13-14 knots at 20-30 days, enough to stalk any SSN in combat area.Even the likes of seawolf/virginia wont be racing at 25+ knots outside of transiting area
>>64759157*flies towards you*
>>64759195There are simply too many reasons why your assumptions are straight up incorrect to get into, but to answer your question>Why are they so stealthyBecause below say 5 knots, they are virtually silent. Add to that they are small, so hiding from surface sonar is easier given the right conditions.>Tracking anything at 13-14 knotsYou *might* be able to track an alpha, if he is close>.t submariner
>>64759195FC+Li-ion is probably the best combo for non-nuclear decent endurance.
>>64759283>You *might* be able to track an alpha, if he is close With a combo of towed array, flank array, bow array, sail array and micro-puffs (or equivalent system), plus good sensor fusion/processing, you can track a lot of things.
>>64759169It's almost like... a submarine is a tool... and you use a different type of submarine for global power projection and a different type of submarine for pure defensive navy duties.............
>>64759283>Because below say 5 knots, they are virtually silent.Not sure about this, since that question isnt mine, but anyway, pretty much any well maintained boat would be dead silent at that borderline turtle's crawling speed.>*might* be able to track an alphaor just in coordination with other ASW assets. ASW isn't some wild west duel, you know that, right ? AIP boats enhanced endurance is very useful as a long range area denial asset>>64759293pretty sure LIB is meant for dashing maneuver, PEMFC always was the main underwater propulsion
>>64759157It helps when your opponents are gimping themselves due to it being an exercise.
>>64759465The exercise would be pointless if the surface commander were to issue a directive stating "German sub entering search area from S-SW". The idea is to detect it starting from a completely unknown position. In an actual combat situation, the enemy won't be courteous enough to announce their approach vector.
>>64759625Sure. But the nature of exercises gives submarines, and specifically diesel submarines, a huge advantage. This goes double for international exercises where you might not want to show every card in your hand, even to allies
