why couldn't they make a nuclear stirling engine and forgo noisy turbines? wouldnt even need to get your fuel to critical mass, just use natural decay heat from highly enriched subcritical plutonium cores or something-- could use several to generate the heat you need and then the ocean provides the cool side for the stirling someone who is smart with math and engineering and poo poo tell me why this is stupid pls

Sterling engines have a lot of issues, mainly metals. You have such a wide difference of temperature that you need to have several different metals connected to each other, where they would be expanding and shrinking constantly. Imagine how these pieces of metal are connected. That is a huge weak point. So that is the first problem I can think of. Second, they traditionally don't make much power at all, and the ones built recently in California with mirrors to use the suns heat were still pretty huge and didn't produce much. Third, they just are not better than our current tech of using the nuclear power to heat water, then boil different water and use that in a steam plant. EDIT: Just another thing, they require a source of heat and a heat sink. Heat sinks are traditionally the water you are nearby. If you go to certain parts of the world this is really hot or really cold. This means the power you could create would always keep being wildly different.

Among many other things you can't really control the heat output from decay heat like you can with a critical reactor. You want to be able to turn it down and, most importantly, turn it off.

WAY too big. A reactor using stable decay heat as a source of power would have to be way too large to be feasible for a submarine. Second, the main reason diesel/AIP are used is because they are quiet....VERY quiet. And anything nuclear power-related will have main/aux systems that are not quiet (comparatively), thus defeating the purpose.

My boat (the 688) did an op against the entire Nimitz battlegroup who also had a 688 class escort in 96 or 97 I forget. We popped a flare on them while about 500 yards away. Carriers have no ASW other than the ships around them and aircraft. They had sent the battlegroup to the far north of the op "box" to try and fool us so they could sneak by alone in the south of the box. Oops. edit : also we detected them at a really loving insane distance also thanks to a sweet sweet convergence zone. ded fucked around with this message at 06:07 on Apr 2, 2013 |

Was this before or after the S-3 got retired? I know airborne-ASW is pretty terrible but the threat of SONOBOUYS EVERYWHERE might have helped a little bit, having only helicopters afterward. I'm also sure that being able to get detection at extreme range with the CZ helped plot intercept too.

S-3's weren't retired until the mid-2000's, so they definitely should have been out hoovering around in 1997.

Did the joker of a battlegroup commander who planned that maneuver get his rear end reamed later on by higher up, cause that just sounds like the most ridiculous loving thing ever. Surely the purpose of the OP was to get some realistic training, not to gently caress about gaming it so that you 'win'. Cause seriously, isn't that like millions of dollars worth of fuel for the battlegroup to gently caress off north.

I'm also sure that being able to get detection at extreme range with the CZ helped plot intercept too. We did not get any aircraft until after we took shots of them with the scope and shot flares up. The CZ helped for sure. They also tried to run only 2 screws to throw us off. The problem is military screws 'look & sound' a lot different on sonar. Also this was part of our TB-29 testing before our westpac. That also helped.

P-3's may not be the end all be all, but the P-8 is a scary, scary machine. I just went up against one in a recent Exercise, and those motherfuckers were the bane of my god drat existence. I can't really go into more detail but...drat. I had to totally rethink my outlook on MPR aircraft.

And personally, I'd be pissed if people were discussing ways to dissolve HY-80, considering my natural aversion to water in the people tank, so I can understand people's angst when discussing counter-jamming IEDs, which kill people.

Ten year old data, and most of the sub warfare stuff is pretty much out there, as indicated above. Hell, you can read about any of this in a Tom Clancy novel. I'm pure civilian and I'm keeping up pretty well. The poo poo about Nimitz loving off from the rest of the BG, though...  I Let's not ruin what I think is a really cool thread (I've always been fascinated with submarines/sub warfare) with trouble, please. Be safe rather than sorry if it keeps the thread open.

Questions from someone who knows basically nothing about submarines apart from the obvious-- 1. These AIP subs--they can't possibly move very fast when running on LOX can they? I imagine they're pretty much stuck sitting still and listening. Is this true? 2. Why doesn't the US have any AIP subs for coastal defense? Would it just be pointless for us? 3. How quiet do you have to be when serving on a submarine? Is it like whispers only when you are up in some country's private parts?

Hauldren Collider posted:Questions from someone who knows basically nothing about submarines apart from the obvious-- 1. The AIPs get up to about 20 knots or so submerged. Not sure how long they can sustain it (obviously not as long as a nuke boat.) You're thinking of diesel boats running on battery. 2. The question doesn't really work. The US doesn't have a huge coastal defense problem; we don't have pirates sieging our ports or a viable threat of amphibious invasion. The kind of small-boat drug-running, human smuggling etc that does go on is better dealt with by Coast Guard cutters and the like. We also have huge, huge coastlines. AIP boats are constrained in total range, time on station (by food stores as much as fuel), average speed, etc. They make sense for countries with limited littorals (Sweden, Israel etc) but the geography of pretty much anything the US wants to do requires the endurance of nukes to do effectively. 3. Generally we just used flashcards and Post-its. Snoring was strictly prohibited, they hid all the Rice Krispies boxes and you were required to sit to pee.

We spent weeks at UQ. Our coners actually complained because they were getting behind on their crews-mess movie watching. UQ means no after watch cleanup. One COB pushed for a 'patrol quiet' which was just like UQ only you still had the hour of cleanup, because "ORSE is coming." Made taking the spec op seriously a little harder.

We spent 2 weeks on RFUQ, and while I hold no special love for field day, the boat was so incredibly disgusting it was unbelievable. I held a new respect for constant cleaning efforts. It took us 2 months of 3 field days a week to get the boat presentable again. While the first 3-4 days of RFUQ are cool, after day 4-5 you start to go god drat crazy. You are out of movies, sick of reading, and your normally enjoyable rack hobbies have become loathsome.

Baloogan posted:Do you guys pressurize the air inside the sub? Inside the hull pressure is kept at 1 atmosphere (give or take.) You don't need to take SCUBA-type ascent/descent precautions for nitrogen absorption or anything like that. The pressure hull is very strong to handle the difference in internal / external pressures. This is also why the hull compresses somewhat as you dive. And if you get a hole, water blasts in instead of just kind of trickling.
