According to PBO's numbers (including taxes and so) ... T26: $77 B / 15 hulls = 5.133 B / hull T31: $27 B / 15 hulls = 1.80 B / hull (50 B savings) ... seems like there are no cancellation costs or penalties, and this works with 3 T26 + 12 T31 = 3× 5.133 + 12× 1.80 = 37 B that is $40 B...

You are certainly right, however training costs may be offset by far by the reduced costs due to reduced crewing requirements. Looking to other navies around, most have (or point towards) two or three surface combatants: UK (3), France (3), Italy (3), Denmark (2), Holland (2), Spain (2)...

Basically that's the idea behind Type 31 frigate for the Royal Navy. A cheap platform, both to build and operate, with space for unmanned vehicles ( either air, surface or underwater) and future upgrades. It fills the gap between OPVs and Type 26 (city class), lower the crew requirements down to...

Maybe you refer to this one... but it's a Cormorant, sorry. http://www.navy-marine.forces.gc.ca/assets/NAVY_Internet/images/news-nouvelles/2020/hdw-at-sea/harry-dewolf-1.jpg

I think this comparison is not fair. Can't compare helicopters, which are usually bought/manufactured/supplied by dozens to vessels, rarely ordered beyond ten units (only RCN Type 26, US Navy ships and a few more examples).

A good feature of both Japanese and Korean shipbuilding structure for their respective Navies is that the two companies do build same ship-classes (and boats): Mitsubishi/Kawasaki heavy industries or Daewoo/Hyundai. The fact is that we're talking about only one Polar icebreaker, but if we...

More on Davie and the CCG's icebreakers: http://www.canadiandefencereview.com/news?news/3024 There is a statement there I don't fully understand " This includes the first fully converted icebreaker CCGS Jean Goodwill which, along with the delivery of CCGS Captain Molly Kool, represents...

I fully agree. Just to remind an old and closed dispute.

From the previous pdf it seems like speed is finally 27 knots. Nevertheless they're so smart as to avoid stating "TOP speed". Might Alion be right on his claim about speed? Only a few ones will know, I doubt the final figure will ever be public, for obvious reasons (reserved data).

Why not? The AOPS already has got some round holes at the fore ... for oars, hahaha. :-)

Not sure this is the correct thread, but it might be... I just want to share an interesting article on Russian Arctic and Sino-Russian relationship. Hope you enjoy it. https://www.aspistrategist.org.au/russia-and-china-in-the-arctic-assumptions-and-realities/

Thanks a lot for the interesting links. Don't want to dissapoint you, but it's also good to look at what our allies do. Astute, Barracuda (Suffren) or Type 212 don't have VLS fitted, even though they have been launched in the last 20 years, meaning VLS were already fitted in Los Angeles class...

Buying just 4-6 Astutes or Suffrens, would be nice especially to patrol the Arctic. The time for such deal is now, for UK/ France to put them in their production line. In one decade they both will end their SSN building program and start with their next generation of SSBNs. Purchase should be...

In the summer-2020 number of MEJ there is an introducing article to CSC. From now on MEJ (maritime eng. journal) is available at https://www.canada.ca/en/department-national-defence/corporate/reports-publications/maritime-engineering-journal.html Wish you enjoy it.

The UK said they were going to build 8x T26 plus 5x T31s. Up to now have order only 3 & 5 respectively. Wouldn't be much surprised to finally see 6 + 8 due to the high cost of the T26. Similarly the RCN could end up with 6-9 x T26 and 9-6 x T31 or equivalent, but at least no less than six units...

Both Japan and south Korea are good examples of planning  and continuous production, both for warships and subs. Long times between batches make loss of design and know-how capabilities. These are to make a case study. Back to korean boats...

Let me drop an open question for which myself have no clear answer... would it be smart to buy 4 SSNs from UK (Astute class) or France (Barracuda class)? As they are, with minimum canadianizing to avoid or minimize cost overruns, project risks and delays. Both countries will finish their...

AIP usually needs a big amount of stored LOx (liquid oxygen), either for the stirling engine or for the fuel cells, so that oxygen needed for the crew to breath for 2-3 weeks is only a small fraction of the stored LOx (quite below 5%). Replenish oxygen to the boat in case of fire should not be a...
