Because ice may block the inlet of the duct and also the propeller inside the duct. Additionally electric propulsion is preferred in ice because electric protections would trip if the propeller gets blocked. A diesel engine may get damaged in that case. Both of them are way above 5,000 tonnes...

Fully agree, I don't consider electric propulsion as complex. Both the MCDVs and AOPS have It. The only issue is how to reach 25 knots. a) with two or four diesel engines (added) b) with one gas turbine (could be the LM2500+) c) a combined (but more complex) solution like two diesels (for...

Since the WARP (central waterjet) is not a good option for an Arctic vessel, I would add two electric motors (about 2.0 to 2.5 MW each) for electric propulsion up to 15-16 knots. Obviously, the diesel generators should be dimensioned (rated) accordingly.

Well,... I meant SK 5 (+2 option), DE 5 (+2 option). Not all the eggs in the same basket, and some margin to benefit the best performing.

Let me set a weird guess: June 29, 5 each plus option for 2 more (each). I doubt I win but ... why not?

With all the capability being drop into the design (+25 knots, 16-24 VLS cells, 60 days endurance, PC6 or PC7, etc) I imagine that the CDC will end up in the range of Meko A-200 (3400-3950 tonnes). Interestingly that range is similar to the Mogami and Damen 11515. Still about half the crew of...

So close to Germany that he could announce something from there in the evening. :unsure: ... or maybe reassure Germans while PM makes the announcement of Koreans selected.

I believe that those quad-packed JAGM launchers could be mounted behind the stack, where the EXLS VLS were originally placed. 3+3 launchers, total 24 JAGM, would help. There was also an interesting picture of a rotating mounting for easy reload. Might be that a few more, of the "below deck"...

Why not joining the European multimission Corvette? With the Frenchies out, decission-making process will be faster and commonality with US equipment/standards increased.

6+6 or even 6+8 would be nice to replace the MCDVs. 6 light frigates capable not only for coastal defence but also to be deployed to NATO drills, combat piracy or sail along the RCDs. With some AAW defense (at least point defense), helo and hangar. Plus 6-8 OPVs with low crew requirements...

The ideal nuke propulsion for a Canadian sub would be a "nuclear battery". A small reactor of about 3 to 5 MWe (electric) with low maintenance, few moving parts ("primary circuit" based on convection, not pumps), and replaceable after 8-10 years. In line with Westinghouse's eVinci being soon in...

I agree, and that's one reason why I advocate for the MCDVs to be replaced by ... 6 corvettes or light frigates (like Type 31 or the previously called European Patrol corvette), in the range of 4000 tons and 90 crew, capable to take some load from the Halifax/CRD, and ... 6 small OPVs, around...

Sorry, I was not clear. Edited: (my previous reply was long and even more confusing) I was replying to Suffolkowner, so I suggested 2+2 (as he did), each yard building their own class, not as before when I (and some others) assumed same class being built in different shipyards, which is...

For the sake of building efficiency, at this point Arpatuuk should be built at Seaspan, then maybe a second Polar Max at Davie (Levis/Helsinki).
