Re: River Class (OPV) (RN)

Great work, HSM Spey!! The last photo, showing HMS Spey along with Damen Sigma 10514 light frigate/heavy corvette is impressive. Not saying which is better, they have very different capabilities. But both looks nice. Will be a good opportunity to share experiences (as anyway most of the tasks for Si...

Re: Queen Elizabeth Class Aircraft Carriers - News and Discussion

I should have noted it before. But its worth remembering that Mojave wouldn't be the model selected for carrier use. GA-ASI have another concept that takes Protector and adds a Mojave like STOL wing, albeit with longer wingspan, that also folds to get the full naval solution. I prefer Mojave. Simpl...

Re: Queen Elizabeth Class Aircraft Carriers - News and Discussion

Mojave is a great opportunity, much better than Protector at least. At least, it is worth intensive trial. If good handling method be established, it will provide 1: long duration over the horizon radar cover to surface ship targets 2: probable ESM capability over the horizon 3: can be also used wit...

Re: Current & Future Escorts - General Discussion

I do understand the flexibility of Mk41 if CAMM can be quad-packed within. But, not so much against independent light-weight VLSs for CAMM. - The weight difference is huge, so we can be (almost) free of center-of-gravity issue to locate the independent light-weight VLSs - The "depth" diffe...

Like I said, I remember reading it’s dual-packed. I think that’s what the Italians are doing in the PPAs…
Isn’t it Sylver? rather than Mk 41?

Re: Current & Future Escorts - General Discussion

It is still much narrower than ESSM.

Also the fin is compact.

No reason to disable quad pack, I understand.

Re: Current & Future Escorts - General Discussion

As I understand it (read it somewhere, can't remember where) CAMM-ER can only be dual-packed, because the body is wider than the regular CAMM. CAMM-ER is narrower (significantly) than ESSM. ESSM can be quad-packed in Mk. 41 VLS. As such, CAMM-ER can be quad-packed in Mk.41 VLS. Also, I read somewhe...

Re: Royal Navy Gunnery Discussion

Each RIM-116 is over $1.4m each. SeaRAM holds 11. So straight away you're looking at around £14m just in missiles. Just to fill the launchers. Add in the conversion costs of an existing Phalanx mount and I'd wager you'd get little change from £25m per equipped unit. And thats before we get to the c...

Re: Current & Future Escorts - General Discussion

So we have typically 3 options; Option-1 = go without any sonar and focus on global patrol sloop tasks, rather put resources on improving other ASW assets. Option-2 = go with ATLAS sonar family. Option-3 = go with Thales sonar family. Option-2/3 will "rob" resources from improving other A...

Re: Current & Future Escorts - General Discussion

With off board systems and multi statics the age of the specialist manned ship is coming to an end. It will no longer need to be the ultra quiet passive receiver, it will more likely be the active pinger with off board systems being the silent receiver. I would have thought the opposite, as the pin...

Re: Current & Future Escorts - General Discussion

1: Adding a hull sonar to T31 will not make it "an ASW" escort. I think all agrees here. Yes I agree. However an asset can be a credible deterrent long before the shooting starts. Mass is in many instances as or more important than cutting edge capability and RN desperately needs more mas...

... Pointless arguing over names and designations that are constantly changing as technology evolves but one question, how many classes of Frigate has RN introduced since WW2 without a hull mounted sonar. Zero. Why now? Because SSK/SSN is even more quiet, and USV/UUV-based ASW is coming soon. Every...

Re: Current & Future Escorts - General Discussion

To make the point in a different way, if the RN (in a lead role within NATO) wanted to ensure dominance of the North Atlantic (inc Artic) above and below the surface what fleet composition is required? Increase the ammo stock by a factor of four. Buy, 5 more T26 (replacing T32 :D ), 3 or 5 more P-8...

The idea that the UK is going to produce a class of Frigates without a hull mounted sonar or a tail is now completely absurd. Why?

Re: Royal Navy Gunnery Discussion

A big part of my confusion on the RN Gunnery is that if the Bofors 40mm is the right answer for the T31's, then why was it not also the right answer for T26's? If the Bofors 40mm is the best option for dealing with fast attack boats, USV's, UAV's etc then I think it should be the RN's primary gun o...

I have asked before if the Phalanx is till suitable as a CIWS in the era of hypersonic anti ship missiles. They are moving so fast that even if the Phalanx hit the missiles in that 1nm, the sheer speed of these new hypersonic missiles mean would still hit it's target. To my understanding, Phalanx i...

Re: Current & Future Escorts - General Discussion

No big objection adding a CAPTAS4-CI to T31 will "help" the situation. Rotating the system will be also good (but you cannot rotate it, when the sonar system itself needs maintenance, which is surely needed), and it will only cost "so-so". Also, adding the ATLAS low-frequency act...

Re: Royal Navy Gunnery Discussion

Replacing the four five with a 57mm on the T45s will cost money. As long as there enough ammunition stocks I can see the T45s staying as they are. With CAMM and Phalanx what is the need for the 'smarter' 57mm rounds? Ben Wallace said there will be the money. What will NOT easily increase is manpowe...
