Interesting read, applicable to Canada, on how Portugal was able to sail an AIP sub under Arctic waters. https://www.euronews.com/my-europe/2026/04/22/how-portugal-shaped-canadas-new-submarines-and-fine-tuned-arctic-defence

Chuck Hill of US Coast Guard fame did an interesting piece on the CDC: https://chuckhillscgblog.net/2026/04/25/canadas-team-vigilance-opv-continental-defense-corvette-an-update/

I think it's 30 - 16 initial order, plus long-lead items ordered for a further 14.

Several renders of the proposed new Mid-Shore Multi-Mission Vessel (MSMM):

Right, but based on the Brits, it looks like the time to build their T26 is around 7 years, versus 3.5 average for the FDI. It was just a question, not a criticism...

MV-75 is very close to being fielded. One would hope this is an option under consideration for nTACS. https://www.military.com/feature/2026/03/27/mv-75-armys-new-aircraft-and-future-of-air-assault-warfare.html

I don't disagree, but I thought one of the design principles for the first batch of 3 was to use mature and in-service systems to reduce risk as much as possible?

The Hunter class are reputedly slightly wider, which I My concern is LEED is largely still in development. It's remarkably hard to find any information on where this program stands.

One of the best looks at the changes introduced in the recently released updated River class model. Interestingly the mention of space for another 8-cell MK41 is discussed again...

No, it (the Dosan Ahn Chang-ho, a batch 1 sub) was commissioned in August 2021. You might be thinking of the first batch 2 version.
