Canadian River Class Destroyer Megathread

[Underway]

I'm not surprised as it follows the trend of ejecting non-AEGIS integrated equipment wherever possible to seemingly simplify and speed up the design finalization/construction process for atleast the first few vessels. The RCN is desperate to get the River class under construction and in the water in order to start retiring the Halifax class, so it makes sense.

My guess is also that weight and space are potential concerns, as the Italian 5" gun is larger, heavier and has a substantial internal footprint. The 5 inch Mark 45 Mod 4 apparently has a weight of approximately 24,700kg~ in its largest form, while the OTO 127/64 LW has a weight of 33,000kg~ (+ or - 5%). The Italian gun also comes with a multi-drum automatic loading system which seems to take up more space than the BAE equivalent.

Its equal parts risk reduction and dealing with Leonardo.

I've attached some images of both systems below for folks to compare.

Ultimately given the rumours and ongoing concerns with related Type 26 derivatives having eaten up substantial amounts of reserve weight for future upgrades just to implement the changes required, I am not surprised we are seeing some of the "gold plating" be removed and still good but obviously less capable design. The Italian gun has much more advanced/potent ammunition choices (more costly/complex though) for dealing with a variety of targets (drones), alongside a faster rate of fire and much deeper/versatile ready magazine system. This is definitely a tradeoff however if it can get back weight and space (potentially for more VLS?), it obviously must be important to be giving up important capability.

Here’s hoping there’s some positive trade off in swapping out the main gun. I have to say my enthusiasm is waning a bit for this ship, in certain respects. I know it’s going to be a generational leap over the HALIFAX and I know it’s going to be a world class sub hunter. The issue is that it seems to be suffering a continual watering down of its capabilities. At first, it was looking to be the most potent Type 26 derivative and probably should’ve been, given the Aussies and Brits have dedicated AAW vessels. But, we went from 32 (or more) VLS cells to 24. I think that’s a significant reduction. With 32 you could have loaded out 24 SM2 missiles and 32 ESSMs. Then, it became less of an issue because ExLS was included. So, 24 CAMM became part of the package or whatever else could be launched from them. Then, that got chopped. Ok. RAM time…admittedly, there wasn’t any thing concrete about which system was being looked at, whether SeaRam or the 21 cell launcher, but at least with two of the latter, there’d be a compliment of 42 point defence missiles to maybe hedge your bets on more Standards than ESSM’s in the main vls.

But, it seems like there’s only one according to the latest (admittedly not confirmed) info.

Finally, now it looks like the exceptional main gun with its high firing rate, Vulcano long range projectiles and various other desirable attributes is being dropped in favour of a lesser unit.

Forgive my frustration, and I hope the tradeoff is measured in getting ships in the water sooner, but I’d be lying if I said I wasn’t waiting for another shoe to drop before the design gets finalized.

Yep. Rules that you follow???? That's for losers.


Welcome to the RCN.

Well the thing that hasn't changed is you can't beat the radar nor the CMS. Battle prove

To keep your enthusiasm, the sensor suite and EW package are going to be better than expected. The data sharing and connectivity are ridiculously high. But that's not something that's easy to explain or get excited about if you haven't been working with that stuff before.

It actually does help, … the part that bothers me, is that it feels like the ship is turning into an exceptional ASW vessel, with strong ASuW credentials, but isn’t fully stepping into the role that the 280’s once played, though the situational awareness, comms and networking probably make it a far better Command ship. It also feels like some of the stated goals are being diluted (vis a vis land strike). With the reduction in VLS cells, the choice of main gun becomes more of a priority if bombardment is still on the list of priorities. If these ships stick with the task force doctrine, I guess some of that wide area missile defence vs land attack horse trading in the VLS will be mitigated, but I have honestly wished from the beginning that there would be a second vessel more dedicated to aaw (like Alvaro de Bazan derivatives). I really worry that the lack of missile depth will be a lingering concern, particularly if the first couple of CSC are paired with CPF’s in a TG.
