I read up a bit on this gun. From what I read, the Mk38 Mod-4 (30mm) and the older Mod-2 and Mod-3 variants differ primarily in their weapon system, mounting lineage, and sensor/fire-control integration. While the Mod-2 and Mod-3 use the 25mm M242 Bushmaster gun, the Mod-4 utilizes the 30mm...

I believe this is the same gun (Mk38-Mod4) as that planned to install on the River Class. A also note a defence blog is claiming the US Navy is procuring more of the 30mm Mk38 Mod 4guns (replacing the existing 25mm Mk38 Mod3 on USN ships).

In my view its one of a number of viable strategies, to wait quietly at choke points to/from the Arctic. One should note though, Russian submarines need not transit the Labrador Sea nor Berring Strait choke points to enter the Arctic. So waiting at choke points is not a 100% fully complete...

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...
