    Canada Two decades old Canadian Navy investigation into Amphibious Assault ships

    Some further speculation on this topic ... It is worth noting that a precedent for such an arctic capable LHD vessel already exists: France previously designed and built two "Arctic-hardened" Mistral-class ships, the Vladivostok and Sevastopol, for the Russian Navy. Although the sale was...

    Canada Navy Surface Combatant (CSC) Program

    A minor point of curiosity for me, is will the Canadian River Class (type-26) , and to a lessor extent the Australian Hunter class (type-26) in their design, dedicate a small compartment near the main deck passage way hatch, for stowage of diving equipment for embarked, part-time, ship's divers...

    Pondering this some more ... While L3Harris WESCAM was awarded a general Visual Surveillance System (VSS) contract in late 2025, the selection of the specific Electro-Optical Sensor System (EOSS) model for the River-class has not been announced and likely not yet publicly finalized. I...

    Months have gone by and I have not seen any press release to indicate L3 Harris WESCOM with their EO/IR equipment is to be a subcontractor to MDA for the EOSS (as part of that noted $60-million contract). So I am still puzzling here as to more precisely as to what the $60M contract entails. I...

    Canada Navy Canada SSK program

    The news on the Canadian Submarine Project in the past couple of weeks has been pretty much focused on the competition between German TKMS and South Korean Hanwa Ocean and Hyundai Heavy Industries (HHI) in the subject area of proposed industrial offsets to Canada. On a slightly different, but...

    Canada Navy Surface Combatant (CSC) Program

    I read the 32 cell on the internet, but when i dig further I believe that what I typed above is wrong. In fact the wiki on the Spanish F110 indicates a 16 cell Mk41 VLS. So that is smaller than the 24 cell VLS on the Canadian River class, and frankly that makes more sense from a forward...

    If i typed BAE-5-inch heavier than Lenardo 127 mm LW, then that was a serious typo on my part. The BAE-5 inch is lighter. I took a quick skim through just now, and i could not spot my error - but regardless, my english language phrasing could be improved. So yes I definitely intended to...

    I believe the under construction Spanish F110 frigates plan to also (like the Canadian River Class Destroyer) have the AN/SPY-7 radar (hence possibly similar upper weight), and both the Spanish F110 and the Canadian River Class plan to have a Mk41 VLS forward and a Leonardo 127 LW Volcano gun...

    A few weeks have gone by and there is still nothing firm to support the speculation that the Leonardo 127mm gun could be swapped out for a BAE gun. I do note going back five years, Leonardo announced they had received a contract to provide three 127mm Leonardo guns, one each for the first three...

    Canada Navy Surface Combatant (CSC) Program

    Following up on the speculative possibility that the Leonardo 127mm gun might be replaced with a much lighter BAE 5-inch gun (so to reduce the weight forward), I tried to dive into looking at what Fire Control radar might be chosen for the River Class destroyer as the Leonardo NA-30S may no...

    Canada Two decades old Canadian Navy investigation into Amphibious Assault ships

    Pondering this some more, while I like the idea of Canada having ships with ambibious assault capability, that could be useful for peacetime disaster relief, Arctic base support/staging, capability UN support operations, I believe it highly unlikely. Nominally to maintain one warship operation...

    Just a confirmation of what South Korea has already claimed, where this news article notes a KSS-III-batch-1 recently completed a mission of about 7,000 km. Presumably the KSS-III-batch-2 range will be equivalent or superior.

    Further, if weight is an issue (and hence potentially leading to consideration to instead procure the BAE 5-inch gun), it entails a different fire control radar than the NA-30S Mk2 as I am not aware of the NA-30S Mk2 ever having been used with a BAE 5-inch gun. I have read that both Saab CEROS...

    Canada Two decades old Canadian Navy investigation into Amphibious Assault ships

    Related to this topic, a couple of days ago, the press is reporting that the commander of the Royal Canadian Navy (Vice-Admiral Angus Topshee) has floated the idea of an ice-capable amphibious landing ship to move troops and equipment around the country’s Arctic — and perhaps elsewhere. For...

    Canada Two decades old Canadian Navy investigation into Amphibious Assault ships

    I have not been tracking a lot of Navy stuff, so after stumbling across some obscure references to a year 2006 activity by the Canadian navy in regards to amphibious assault ship, I thought to dig further. Presumably such a ship could be useful not only for wartime , but also for disaster...

    Yes, i agree there will be integration costs to integrate the NA-30S Mk2 firecontrol (for the 127mm Leonardo gun) to CMS-330. Having typed that, i think it as back in 2021, when the RCN changed from preferring the BAE 5-inch gun to the Leonardo 127mm gun. The decision was made then NOT to go...
