My understanding is for the River Class the intent is to include 2 x mk38-mod-4 30mm guns aft, one port and one starboard. I note the WarZone has a recent article with some images of the mk38-mod-4 gun on a different ship class (and another image here ) . Also of interest is an image of the...

Trying again (for me) to move away from my over focus on Arctic sustainment aspects ... I dug into countermeasures a bit. I have been pondering what soft kill countermeasures might come with the Type-212CD submarine. Internet sources speculate re: the "Sea Spider" but that is a hard kill...

Reference batch deliveries (as defined contractually) for the Type‑212CD submarine, I think the Wikipedia article on the Type‑212CD is possibly misleading … or, if accurate, it reflects something not in the public domain that I can find. In the “List of boats” section for Canada, the table...

Given TKMS have been chosen as the preferred supplier for the Canadian Patrol Submarine, I was curious about the progression of the Air Independent (AIP) system in TKMS boats. From open source estimates (where this could be inexact) I put together the following: Type 212A — 2005 PEM fuel-cell...

I've been puzzling a bit over this view of mine, as to how to best present the idea. Currently Canada-USA relations are not the best they have been due to the tariff 'war'. Further, as I noted Canada, and USA don't have an identical view re: sovereignty in the Arctic. Hence now is not likely...

I did not realize the dry dock by St. Catharines, likely the one at Port Weller, was still in operation. This brought back memories about the Port Weller shipyard from my RCN days in the mid-1980s. In November 1984, HMCS Huron was in dry dock at Port Weller Dry Docks at St. Catharines Ontario...

I was thinking (and still am planning) to move my comments away from northern deployments. But while reading some internet articles, I ended up stumbling across accounts of the O-Boats and this observation of yours came to mind. So reading about such in the unclassified open press articles...

I also read that Corner Brook went into the Arctic again in year 2009, again in the month of August when ice conditions not severe (favourable even - I assume). In short, HMCS Corner Brook returned to Canada's Arctic in August 2009 for Operation NANOOK 09. Some more detail from what I could...

I learned a few minutes ago that the Victoria class is undergoing a needed upgrade with Type-2040 being replaced (?) with what is being referred to as Victoria-class Bow Array (VCBA) with the geometry of the new sonar enabling detection in both bearing and elevation. Likely it provides more...

First let me apologize for this following post , as I am trying to move away from potential Arctic operations of the future Canadian patrol submarine, as I think some are seriously bored by such. But I stumbled across a 12 September 2007, Vol. 10, No. 26 of the Maple Leaf, which describes HMCS...

Clearly most of the above is massive speculation by me - so please treat it as such : speculation. Still - even in these early days, I was curious as to how the Canadian Patrol Submarine's sonar kit might compare to the existing Victoria Class. Of course given there is no contract signed yet...

I think a lot of what you note, need not wait for the first submarine (such as Hydrographic work and further study of ice conditions). It can start very soon. Learning about AIP replenishment can also start now. It need not wait. Your points are noted, ... but I will add to that, planning in...

While not space warfare, ... I thought to note here some Canadian military space history, as I recall (all of which is unclassified public knowledge, for those who look - so no secrets here, although perhaps not all are aware of such). My reading indicates Canada's military space footprint...

Hi ytz. My recollection is that international arrangements for spacecraft end-of-life disposal have been in place for quite a long time. I believe for Low Earth Orbit (LEO), there are de-orbit guideline dates back to the IADC guidelines of 2002, followed by the UN/COPUOS guidelines in...

lol ! Information on such sonars is in the public domain. One simply needs to go to the different manufacturers sites, read up on their equipment, maybe check a wiki or two ... Obviously it helps a LOT if one has a naval background. It helps if one also studied such in their own time when in...

I suspect the above may be too detailed to be of interest to most on this thread (especially without further information). Out of curiousity I dug a bit deeper, and this is what I learned in case any other than myself find such of interest: An advantage of the Kongsberg SA9510S MkII Mine...

On the topic of possible sensors for the TKMS Type-212CD submarine, I read that the ESM planned for the TKMS Type-212CD submarine is likely to be from Indra Group but I have not as of yet read of any designation (such as Pegasus)...

Lets change the focus on the thread. Any views or speculation as to what the TKMS proposal for the Type-212CD sonar may be? The wiki on the type-212CD lists (but I do not know if accurate): Mine avoidance and navigation: Kongsberg SA9510S MkII Sea bed navigation: EM2040 Mil and EA640...

I found this 10-Feb-2026 Globe and Mail article of interest; Globe and Mail: New submarines will require extra gear after delivery to operate under ice, navy head says I think others on this forum will also find that article of interest if not already read. For example Vice-Admiral Angus...

Further to this, I note : Defence Investment Agency seeks input from Canadian industry on future submarine fleet sustainment - Canada.ca If I speculate on that (speculation being the 'operative' word), that suggests to mean this pretty much refers to Halifax/Shearwater area and Esquimalt area...
