Thinking about this, I think that latest press release was for LEO (Low Earth Orbit) satellites with military Ka band communications ( I am unsure ) which if that is the case, it is likely not for submarines, as putting a Ka band SATCOM antenna on a submarine periscoping antenna would be a very...

Further on a related note to his, various news sources are reporting Telesat LEO ULC (Telesat) has been given a contract from the Government of Canada valued at approximately $2.3 billion to deliver the military Enhanced Satellite Communications Project – Polar (ESCP-P). Some references: The...

It takes time to build modern warships. Thankfully the ball is now starting to roll. Perhaps add: 2027 - JSS - Future HMCS Protecteur 2028 - JSS - Future HMCS Preserver ... and frankly IMHO we need more than just two JSS. ... Not to mention a mobile base ship (or two) for the Arctic and the...

I think I have mostly exhausted (for now) any top-level exchange on Arctic operations in the past re: conventional submarines. Out of curiousity I surfed on the web to see what I could find in terms of the RCN High Level Mandatory Requirements (HLMR) for the Canadian Patrol Submarine Project...

The WarZone now also has an article on the GMF 140 Rheinmetall warship frigate/destroyer concept. From that article: ... .... .... ---- I think its pretty clear, this is not intended to be a corvette, but rather its aimed at a much larger warship requirement.

Well the River Class is 150 meters (about) so at 140 meters a 140 meter frigate its almost as long a a River class. As for the 140 meter long Type-31 ... lol ... in today's political climate of USA unilaterally breaking existing trade agreements to apply tariffs on Canada, and open talk to...

No sooner did i type that, when I spotted yet another Rheinmetall page: https://www.rheinmetall.com/en/media/news-watch/news/2026/08/2026-08-03-rheinmetall-presents-the-gmf140-the-next-generation-frigate which states: .... Which is consistent with what Naval News and Army Recognition...

That 'soften's this a lot IMHO. The Rheinmetall marketting page states: ... so its not specifically aimed at North America. Makes me speculate that some naval/military news editors were having some fun with a spin view of their own.

Based on that Naval News article, it claims the GMF140 is designed to integrate US sourced primary radar options, with AEGIS Combat System; and 64 Strike-Length Vertical Launch System (VLS) cells, and CMS330 Combat Management System targeting North American naval projects? Targeting North...

Out of curiosity, I did some digging to see if anything in unclassified areas on the Internet as to the Electronic Warfare system planned for the Type-212CD. Being a conventional submarine, despite having AIP, a Type-212CD will still be required to run its diesel engines (so to preserve AIP...

That was my thinking also. ... Reads to me to be very dangerous. My having typed that thou, I think it may be feasible to create such on board a large ship (reducing storage needs on the ship) - where I suspect (but have not confirmed) that commercial mobile containers can be procured that may...

I stumbled across some interesting articles on the Internet, re: modifications recommended for submarines that plan to operate in the Arctic. One such article is the Choi and Lajeunesse paper ( pdf ) listed some interesting changes to submarine design considered appropriate for Arctic...

Given Canada has selected TKMS as the preferred supplier with its Type-212CD submarine, and given there is IMHO a lot to learn about AIP operations, .... I was curious as to which other countries have AIP equipped submarines, or plan to procure such. I deliberately did not include submarines...

Some trivia, I found this article of interest [ Neither Fish nor Fowl: China’s Development of a Nuclear Battery AIP Submarine | Center for International Maritime Security ] where it has in the most part no relevance to this Type-212CD thread, except some sentences that I extracted from the...

Its an interesting question. I note a year-2022 issue of "Starshell" magazine, in regards to the Barbell, states in the year 1961: I could not find any record of Barbel-class submarines (Barbel, Blueback, or Bonefish) conducting under-ice or Arctic investigative exploratory missions. I...

I am also curious about what, if any Upward Looking Sonar (ULS) the Type-212CD submarine may have - and if not a nominal piece of kit, is the RCN planning to negotiate inclusion of this? If so, I assume the negotiation is taking place now (or very soon) as I type this. I note most of the early...

I am puzzling over how the Type-212CD, if deployed to the Arctic, will communicate for long range communications. Often warships, for long range communications, use HF and/or SATCOM. So I downloaded the spec sheet for a TKMS communications periscope/mast (Triton II TMS_2111 -...

After having spent many hours, with interesting reads on early day USN SSN Arctic operations, and prior to that even, early USN conventional submarine explorations of the Arctic, I am coming to the view that the RCN Type-212CD, if they don't receive 'Arctic modifications' ( for example...

Further to what Stoker noted about conventional propulsion submarines, exploring the Arctic, I found more trivia on under ice operation. Obviously, I am currently a bit curious about this, and I do believe it relevant if the RCN is serious about Arctic sovereignty - especially IF the RCN should...

Further on the topic of submarines proceeding under the ice for the first time, I just finished reading USN Commander William R. Anderson's excellent book "Nautilus 90 North". It was not all smooth going for the nuclear propulsion Nautilus in her first transits under the ice, and I found the...
