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.

A100 is CODAD MW PDE. So no need for the WARP if one were to go that particular engineering route.

But there is also something to be said for having a simple ship, that isn't overly complicated.

That! 100%

Especially if you want to build something where production can be ramped up quickly in times of need.

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 Cruise at about 20 knots), combined diesel-electric and diesel, plus the gas turbine.

Regarding WARP, I was rather thinking of the new Meko

Electric propulsion is only complex in the number of things that you have to watch for compared to straight diesels with shafts and Variable pitch propellers, but from a design point of view, I agree that it is not complex.

This said, the Absalon class and the Brits type 31 are four diesel to two shafts with VP. Simple, straightforward, redundant and giving you 25 + knots.
