Not sure I 100% agree with your statement. We have been told that the Type 212CD will have ice strengthening, and with regards to size and buoyancy, it's the same submerged displacement as the USS Skate, which did surface through arctic ice for the first time in 1959. The Type 212CD is said to...

First meeting of the tri-lateral planning group for the Type 212 CD project. I suspect the details will be worked out quickly, and announced later this year. https://www.navaltoday.com/2026/08/11/germany-norway-and-canada-start-preparations-for-type-212cd-sub-contract

Draft is actually comparable: 6.45 for the MPI, vs 6.2 for CCGS George R. Pearkes. It's a longer and broader design.

From the horse's mouth. Interesting details, including what appears to be SPY7, a Mk 45 gun, and RAM launchers, all of which will be employed by the RCN with the RCDs. https://www.rheinmetall.com/en/products/naval-vessels/frigates/gmf-140#anchor-advanced-air-ballistic-missile-defence

More again. Reference to "a procurement project in North America." https://www.navaltoday.com/2026/08/03/rheinmetall-reveals-new-guided-missile-frigate

Quick Google search shows no sign of a Mexican naval frigate program, and the US is developing the FF(X), so I think this is aimed at CDC. Like I mentioned in my original post, this suggests the Germans are under the impression the 105m restriction may have been lifted.

More on this. Canada is specifically mentioned. https://www.armyrecognition.com/news/navy-news/2026/rheinmetall-gmf-140-frigate-unveiling

That's being replaced by a new light frigate class known as FF(X), which will be based on the US Coast Guard’s HII Ingalls Shipbuilding Legend-class National Security Cutter design. So, I still think this is being aimed at CDC, unless there is another NA frigate program (Mexico perhaps?).

Hmm. Interesting. I wonder what "North American Naval Project" this is aimed at? If it's CDC, it would appear this project has "grown" substantially. Note the radar in the picture looks like SPY-7... Also note the reference to CMS 330...

This is cool. Anyone aware of this company: GH Power (Home - GH Power) https://interestingengineering.com/military/gh-power-tkms-submarine-hydrogen-reactor...

Irving's Year in Review (2025). Makes for some interesting reading, including some interesting details on the infrastructure updates currently under construction. https://shipsforcanada.ca/images/uploads/ISI_2025-Annual-Report-compressed.pdf

In fact, our HEP phase 2 upgrades are based on similar work done by the USMC on their "legacy" hornets.

I think it's about 400 tons more submerged (2400 vs 2800). Also, the "beam" figure is a bit deceptive, as that includes the outer "stealth" hull. The pressure hull dimension is the one that will be interesting to know, as that what defines the actual useable crew space.

Correct. The C17 FE was narrower by about a meter, in an effort to gain some aerodynamic efficiency. The one that would hopefully get built if they reopen the line is the original "A" model, or the proposed "B'' model. https://avgeekery.com/three-c-17-derivatives-that-never-took-off/

Interesting article in Skies on GlobalEye. Seems to confirm AAR, as well as assembly in Canada (of some). https://skiesmag.com/features/globaleye-in-the-sky/
