This "41" day figure actually includes snorkeling. More accurate information: When evaluating the open-source data for Canada’s Canadian Patrol Submarine Project (CPSP), it is critical to look past manufacturer marketing templates and isolate known design parameters from classified...

For my own edification, I dug into this further, as the Canada-class wiki, erroneously I believe, states "under a 1959 agreement between the US and Canada the US had the right to block the purchase of submarine nuclear reactors by Canada from any third party (i.e. the United Kingdom or France)"...

I read in the Canada class wiki (that USA had a veto over French nuclear submarine reactor procurement by Canada) but when I try to follow it up, I find no agreement where USA can veto a Canadian nuclear propulsion submarine procurement from France. I note the 1959 Agreement Between the...

While nuclear-powered submarines are unquestionably superior in endurance, speed, and sustained presence, I am not convinced they are necessarily the best fit for Canada - especially given the current US administration. The reality is that nuclear submarines are enormously expensive to acquire...

IMHO, while the above post goes into some of the open source debate comments surrounding the submarine procurement program, it contains inaccuracies or at best, unsubstantiated statements regarding both TKMS and the Hanwha Ocean platform. Specifically, the figures cited for the acquisition...

Since my earlier post, additional reporting has added some further speculation surrounding Canada's fighter replacement plans. CBC's Daniel Leblanc reported that Ottawa is examining options beyond the currently contracted F-35 procurement, including the possibility of a mixed F-35/Gripen fleet...

A couple of updates here on aspects indirectly related to this program. South Korea lost one of their older KSS-II (South Korean Type-214 version) in a fire when under refit by HD Hyundai Heavy Industries’ shipyard in Ulsan. https://milmag.pl/en/south-korea-lost-a-submarine-in-a-fire: The...

I have tuned my thinking a bit here ... and I no longer think TKMS has an edge in lithium-AIP experience relative to the Type-212CD from the Type-218SG. While the decision as to what submarine the Canadian government will choose for the RCN is now likely up to only schedule and industrial...

Further research on my part makes me more and more highly suspicious that in the absence of confirmation from the Canadian government that the $5-billion Cdn$ number in the Ottawa Citizen article is likely highly inaccurate. i prefer not to elaborate more on that number.

My understanding is that Polar Class 6 generally implies thicker hull plating and heavier framing in ice belt areas, use of cold-weather steel, modifications to machinery cooling and seawater inlets, ballast tank freeze protection, and strengthened propeller and rudder arrangements to withstand...

My understanding is the answer is "YES". A Canadian Continental Corvette likely needs hull strengthening to operate in the arctic. I believe Canadian VAdm Toshee described the Canadian Continental Corvette as needing to be "not afraid of ice". ie not an icebreaker, but able to go to the...

As I double check on my assessment as to what Corvette class warships cost, I took a look at some current corvettes around the world, dug up a bit on their procurement costs, and then added to such the cost for initial munitions, spares, support, and ship specific shore infrastructure). I...

That is in my view a good point. As near as I can tell the $5-billion originates in an Ottawa Citizen 23-April-2026 article: Canadian military to launch initial steps in new $5-billion warship project and the actual budgetted amount could be far different. At present I can find no official...

The main issue limiting the CDC warship's size/combat ability, as i see it, is the budget, where I read the number $5-billion Cdn $ being bandied about for 15 to 20 corvette's. That equates to only $250 million per corvette (if 20 procured) which very very seriously restricts the amount of...

I note this is a USN Request for Information (RFI) to replace the Mk-20 Mod-1. ie SPECIAL NOTICE N0016426SNB35, Electro-Optic/Infrared (EO/IR) Sight System (EOSS), which I read was published February 10, 2026, where the program was initiated to create a competitive environment for the...

No sooner have a posted (in past few months) speculating about a Mk20 EOSS for the BAE 5-inch gun, than I stumble across an article stating the USN is looking to replace the Mk20 Mod-1 EOSS with a newer EOSS...

I am not fully happy with this speculation of mine. I note on the mast of the River Class, there are a couple of platforms, either of which could be EOSS equipment, possibly for WFOV ... and even possibly for NFOV (or possibly for MDA equipment re: their laser warning countermeasure equipment)...

On this topic, ... and looking at the latest models and images of the River Class, it is very difficult to dicern the details of the various antenna on the images (artists depictions) and models. How is that related to my Raven comment you may ask? Well, the Raven antenna (based on Ramses)...

From an old 'DEFENSECOOP' article ( link : https://defensescoop.com/2023/04/18/in-wake-of-fatal-collisions-navy-accelerates-software-defined-radar-deployments-on-surface-ships/ ) Note the words “as well as providing fire control quality track data to support surface gunfire,” The article goes...
