"High-ranking sources": Canada considering nuclear subs?

[Colin Parkinson]

I often wondered what would happen if the wing of the Bras D'or ever hit anything like a dead head (submerged log) at speed.

They tried to run a Boeing hydrofoil out here on the West coast running from Vancouver to Nanimo, it was defeated by the woody debris, which often measures 2' across. The Russian seemed to be the only ones that were successful in running and building large fleets of Hydrofoils.

We don't need nukes, we wont ever see nukes in my life time...Diesel or AIP is the way to go.  Even the US are considering a conventional sub program again.  They can have 4 to 6 subs for the price of one Virginia.  The Germans are developing effective light anti air missiles for subs and have a 30mm mast mounted MG.  I can't see us fitting these things but we could.  We removed the Sub launch Harpoon equipment but modern up to date gear would take up a fraction of the space.  The Victoria's will be effect capable boats on there own.  We just need to get them running.  The clock is ticking now they have made real progress the last few weeks on the Windsor I just hope they can keep up the momentum.

The reasons for that have little to do with a SSN/SSK performance debate.

Not a cost issue either. The performance of the Virginia-class program has been so good that more boats have been authorized.

The Germans are developing effective light anti air missiles for subs

Missiles breaking the water's surface mark the datum really well.......

Much like aircraft debris reminds aircrew to back off a bit.  > 

IDAS is a game changer for MPA/MH employed in an ASW role.  The datum on page 2 doesn't look too bad either.

Larger subs might also carry UAV/UCAV's on board to provide their own air cover. Subs might also have UUVs that operate in conjunction with the main vehicle, if you need to launch something the UUV will do the deed and take any consequences.

The best things subs can do though is to become stealthier. They already use the mass of the ocean to hide their signature, new developments like "Metamaterials" can effectively bend sonar or radar around the submarine, rendering the vehicle invisible.

Maybe we should start pronouncing it "nukelar", a la Bush. ]

Ahem, let me assist you and oldgate bgate driver both , and possibnly more, Bwa haah haa!!!!

I have communed with the the spirits!!!! and the avatar of the Sith Lord Cheney!!

The correct answer is  `New Clear` weapons policy for the CF!!!

If Diefenbacker and Pearson could do it!!!!

Amaze your friends!!! Impress your enemies!!!

`New Clear weapons`are the way

The Future is glowing!!!

game changer for MPA

Its another consideration but not a game changer, for reasons that don't belong on this website.

IDAS is a game changer for MPA/MH employed in an ASW role.  The datum on page 2 doesn't look too bad either.

They'd probably affect an MH dipper, if they work.

The chances of IDAS reliably working is pretty small. Keeping a finer-optic line intact isn't easy when the two ends aren't manoeuvring at hundreds of knots relative motion, through two different media.

 

[a_majoor]

Subs using advanced avoidance techniques (like metamaterial coatings that "bend" sound around them) are probably far safer than subs which actively fight back against aircraft. Anyway, the rest of the task force has assets to deal with annoying people (and if we go back upthread and look at high speed surface concepts, we are close to having an air battle already).

To make the mix even more confusing, LTA craft can orbit overhead for prolonged periods to supply tracking information to the task force, and if the USN's experiments pan out, surface ships and perhaps aircraft in support of the task force will have laser and electromagnetic railgun weapons to keep enemy ships and aircraft at bay.

A UAV defending a sub would be doable at some point. but having worked with SFU on communicating video just across thermoclines and not across two mediums, I suspect the UAV would be autonomous with instructions to defend said area prior to launch. It would be a one way trip for the UAV. The possibility might be to have one small short range missile attached and a internal warhead. The UAV would hunt any aircraft within the programmed zone until it has destroyed the contacts, run out fuel or was destroyed/struck enemy aircraft/helicopter.

Nothing wrong with that; it is the aerial analogue to a torpedo (especially the older kinds which moved in a zig zag pattern until they struck a ship).

Has anybody considered the fact that you can't go completely silent with a nuke sub? You can't turn the reactor off. You can mitigate noise very well, but its always there. The Victoria class, however, can shut everything down and just passively listen, undetected by subs trying to sneak around without pinging. That's what the brits designed them for. Anyway, in another ten years there will be a clear channel through the northwest passage all year round. As it is now its clear virtually all summer.  We can sit up there and scare the $hi# out of the Russians and the Americans by metaphorically jumping out and saying Boo!

Yes.

Actually Yes you can  the are two methods to deal with reactor noise aside from the usual quieting such raft mounting  just about everything that can make noise or coating in rubber anything that can't be raft mounted. As for the reactor, travel at speeds that don't require the circulating pump  to kick in . Or as the Americans did in one Sub give it a reactor  that didn't need a circulating pump.

There's also moving to variable speed machinery. The Virginia class uses machinery that can be operated at different power levels rather than straight on/off. If they're going slow the pumps are barely ticking over while at flank speed the pumps are running full out.
