Re: Current & Future Escorts - General Discussion

As for the IH class we know that part of the low cost came from having the hulls built in East Europe and fitted out in a naval ship yard and we also know that most top end escorts in the West cost some where between 600 and 900 million to build The Danes did have the Iver Huitfeldt class hulls bui...

Re: Current & Future Escorts - General Discussion

I wonder if the new design has any structural similarities to the Norwegian Frigates, one of which seems to suffer far greater damage from a collision than say a USN vessel involved in a similar incident but with a bigger vessels? The fact that the Spanish will have little or no infrastructure to p...

Re: Current & Future Escorts - General Discussion

F110 looks similar to earlier T26 design variant of new gen T23 before increased in size for large amphib/mission bay and large Chinook flight deck etc. Hmmm, they don't need the Global Cruiser, do they - do we? - I think we do. Esp. as the next batches can be optimised to be "leaning into&quo...

Re: Type 26 Frigate (City Class) (RN) [News Only]

Why would Lockheed, who is the prime on the Canadian frigate program, select a Spanish radar in preference to its own product? Some thoughts on pros for Lockheed going with Indra radar for the CSC, you may come with some cons. Lockheed have a contractual agreement with Indra for marketing radar wor...

We are not even sure if T31 will carry how many CAMM. It could even be zero, because it at least complies the original T31 RFI. We do not know how the requirements has changed (or not) after it.

Re: Current & Future Escorts - General Discussion

CPP and FPP CPP use hydraulic mech on large propeller boss to change pitch appropiate to speed and sea state, more expensive than FPP which most merchant ships use as more efficient as optimised for a limited speed range USN Burkes with its four GTs, two combining MGRs, two prop shafts and CPPs, max...

Re: Current & Future Escorts - General Discussion

unloading the propeller tip decreases the noise disturbance of the water/cavitation by the propeller, but can reduce its efficiency. Type 26 uses an optimised FFP for this reason, whilst FREMM uses a CPP, as always a trade off as though FPP will be quieter at low ASW speeds, its less efficient than...

Re: Current & Future Escorts - General Discussion

Looks like a smaller Iver Huitfeldt class frigate at approx twice the cost, appears high cost driven by having ~ 90+% French content, build time of 2 and a half years, fully equipped GP frigate with AAW, AShM though its ASW ops limited by its noisy CODAD, reinforces my view that the T31 as currentl...

Still not for speed dude. RCS reduction, seakeeping or looks: take your pick.

Not the only personal assumption that crept into that comment. e.g. the Sea Axe bow. Not for speed but for sea keeping.
