Took me a bit to find and get answers to some of these questions. Please bear with me as I develop the discussion. First, a submarine needs to always be able to surface quickly in case of an emergency. Any minor issue can quickly become a major one if you can't get to the surface. I think...

No idea. Maybe Russian? Norwegian? It's not like RCN submariners would tell you one way or the other. They take their Silent Service vows quite seriously (as they should).

The entire point I was trying to make was the Japanese believe that LI batteries are better than any of the below AIP. You'll notice that AIP requires different fuels which require different fuel tanks, liquid oxyegen storage, other equipment like steam turbines or engines. This takes up a...

The Taigei class don't. Just batteries. There's even an interview out their somewhere where the one of the Japanese officials states that AIP is a waste of space on a Taigei class because the battery bank is good enough.

I can't remember the reference but because we were using some (USN I think) battery safety standards JSS went out of its way to force some equipment providers to replace their LI UPS with a different battery type. We were just not in the business of completely redesigning a space with different...

@KevinB like @Navy_Pete said there are ideas to deal with battery Thermal runaway (the proper term, I was doing some research today). LI however don't do well with.. a) high temps, b) pressure changes, c) moisture. All which are present on submarines to one degree or another. There is another...

I hope its the front runner. For two reasons. Its currenly in production and it has VLS for TLAM's. Though the Japanese subs are gorgeous from what I've heard. LI batteries are still a bit experimental though. All things being equal a single LI has power storage equal to four lead acid...

Essentially. The parts of the ship that will be exposed to higher ice pressures/forces have been reinforced. I think its the more modern computer modeling way that ships are being built (and cars/aircraft/buildings etc...). You design the object, subject it to forces in a simulation and then...

Agreed. This isn't anti-military its just NIMBY's. If they wanted to put windmills there I'm sure there would a similar response.

Pedantically it matches a qualification, then a position, then an appointment/position. You don't need to be an NWO to get one (though its pretty hard otherwise). Lets not denegrate each other by pointing fingers and saying one specialist badge is more valuable or harder then another. They are...

To be perfectly honest we just make things up as we go along sometimes. Whatever is in the best interest of the RCN will likely happen when it comes to something like ship names. Particularly with the current Commander RCN who put out a vibe that he doesn't have a lot of time for stuffy makes...

The builder is responsible for the manufacture on their own. The gov't doesn't tell them what to do as the goal is to have industry free to come up with their own solutions to problems. Design for both ships was bought. In JSS case there were a number of changes required to meet certain...

CSC is asking JSS and AOPS what mistakes they made or challenges they had all the time. I know that for network systems JSS was invited to a number of the CSC planning briefings to point out some challenges and things that weren't quite working. The PM's talk on a regular basis and the PD...

I don't disagree. Nav Arch friend of mine pointed out that the limiting element in warship design these days is often upper deck square footage. It used to be tonnage (for armour, engines and guns), and then it became space (for the huge computers and their cooling that used to be needed in the...

AIP subs are in the new defence policy I'm sure of it. We'll see if it survives to be released this fall, and if the new government (whatever that is going to look like) wants to keep it going.

We're a bit to far gone to implement structural change for the CSC program at this point. I can see there being some changes as we move past the initial three ships. And there have been changes to procurement overall, I've spoken to them here a few times.

You should be looking to France for those who carried a lettre du course.

I can't quite see but I think that' the naval crown on the crest and I don't think that changes with the soverigns own crown choices. Thats a pretty skookum crest though. Don't often you get one with a Cannon & a VC on it! Overall the AOPS crests have been quite good.

Not sure if this is actually it or not. The odd shape makes me wonder as that's a bit out of normal for ships crests. However I could represent the fort that he helped take.
