Difference Between Conventional and Nuclear Submarines? Type-032 submarine is best for Pakistan?

Описание: 1: Difference between Nuclear Powered and Diesel electric AIP submarines.
2: 1st a diesel electric submarine cost 200 $ Million to 600 $ Million. You can buy 3-4 AIP subs for 1 nuclear Attack or SSN.
3: Nuclear powered Submarines have edge in endurance & Speed and probably Stealth over AIP subs
4: But Newer AIP equipped are closing this Gap and costs only a fraction of cost of Nuclear Powered
5: A diesel engine generates electricity to drive propeller and power its systems.
6: But there is a problem, Diesel engine create noise and it runs on air.
7: air is limited when submarine is under water. Thus, sub has to surface frequently
8: 1st Nuclear powered submarines were brought in to service in 1950s.
9: Nuclear Reactors are quieter, do not consume air, and produce enormous power.
10: That allows nuclear submarines to remain submerged for months while traveling at higher speed
11: That’s why America has all Nuclear-powered submarines, but other countries operate diesel electric submarines because of lower cost and less complexity.
12: in 1990s submarines powered by Air Independent Propulsion (AIP) technology entered operational use.
13: Sweden made its 60-meter-long Gotland-Class with AIP, it was stealthy & had long endurance
14: today there are 60 AIP submarines operating 15 countries & 50 more on order.
15: China has 15 Yuan-class Type 039A submarines with 20 more planned. 8 for Pakistan Navy.
16: China`s Type-032 is world`s Largest Conventional Submarine with 6,628 tonnes displacement
17: Type-032 has 2 SLBM VLS and 4 Cruise missile VLS. That Pakistan should have bought.
18: Japan has 8 Soryu class submarines and 15 on order. Sweden has 4 types of types of AIP subs
19: Germany has Type 212 and 214, and has exported them across the globe.
20: fuel-cell powered submarines include Spain ( S-80), India ( Kalvari-class) & Russia ( Lada-class)
21: 3 upgraded Agosta-90b class subs with MESMA engines serve in the Pakistani Navy.
Nuclear vs. AIP: Who Wins?
22: Nuclear Powered subs r quiet. 2009 French & English subs collide as they didn’t hear each other
23: Diesel powered subs are quieter as run on batteries for some time but AIP elongate that time
24: on more than 1 occasion diesel subs have slipped passed air craft carrier defences in war games
25: For endurance, it’s a win for Nuclear powered submarines. But AIP subs like Type-214 can remain under water for some say 2 months.
26: countries like Japan, Germany and China that mostly operate close to friendly shores, extreme endurance may be a lower priority.
27: For Speed, Nuclear powered subs can attain 35 knots and Conventional subs like type-214 23 kn
28: nuclear submarines rarely operate at maximum speed because of the additional noise produced
29: US Virginia class costs $ 2.6 Billion. And AIP subs costs only $ 200-600 Million.
30: Crew, AIP sub has crew of 30-60 and Nuclear powered sub has crew of 100 or more.
31: also have heavier armament, such as Vertical Launch Systems, when compared to most AIP
32: a torpedo or missile from a small submarine can hit just as hard as one fired from a large one
33: and if you have more submarines in area then chances are that you will achieve your targets.
34: navies that operate largely around coastal waters are turning to cheap AIP submarines
35:
