Re: Current & Future Escorts - General Discussion

In what sense, 1 T26 is better than 3 T31 (equivalent in cost) when fighting against such boats? Even comparing 1 T26 with 5inch gun vs 1 T31 with 57mm gun, I guess the latter MAY be better, if equipped with Orca guided rounds. Sorry, maybe I am missing your point? [EDIT] ORCA guided rounds, from BA...

Re: Type 31 General Purpose Frigate [News Only]

#note, "A" will not be in swarm, because ASM is very expensive. Iran, a country the UK has common contact with in potentially hostile seas, heavily disagrees with that claim. Iran is a BIG country, not a terrorists. When fighting with them, all weapons will be used. If a frigate faces a s...

Re: Type 31 General Purpose Frigate [News Only]

Yes they can be used as CIWS, but I see no evidence they are effective against a modern ASM. The bigger guns already struggle with legacy subsonic missiles, they have no chance against a faster or more maneuverable target. I see no evidence they are effective against a surface contact either. Every...

Small VDS have been fitted to small craft for decades, the Russians fitted systems based on Helicopter dipping sonars onto the multitude of small ASW vessels. But the technology has vastly move forward. See this "fishery" sonar movie. Fishery, not military... but surely if a SSK happens t...

Interesting concept, but not clear in their article. Initiated from it, we can search several examples for sonars to be carried on it, as well as other candidate hulls. We do not need to invent it, there are some examples around the globe. They tell us the efficiency of those assets. For me, it shal...

Re: Current & Future Escorts - General Discussion

Babcock do not have experience of building complex escort. In general, if you do not know how to build "complex something", you tend to under-estimate the work load (minimum 20%, and in worst case a factor of 2). This is well known bias. So, I won't be surprised if Babcock CEO made a mista...

Donald-san confused by your graphic as it shows Arrowhead 140 starting at ~£280M, whereas assuming Babcock when they proposed it had confidence they could build it within budget of £1,250M for 5 ships. The advantage to Babcock of the Arrowhead 140 was ~90% detail design available as taken straight ...

I don't have a problem with any of the above and I have always supported the idea behind the T31 programme. It's replacing T23's with something like Leander is the part I don't like. I could see the sense in something like Venator or Arrowhead 140 but Leander just seems like a dead end to me. It ha...

Re: Current & Future Escorts - General Discussion

If the T26 programme is reduced by 2 hulls down to 6 that saves around £1.7bn. Added to this would be the T31 budget of £1.25bn. Combined around £3bn. That would mean the first 6 hulls would cost around £6.3bn. BAE would then be asked to reschedule the T26 production line for 12 hulls. This would r...

Thanks. But if there is such money, I think RN should have proceeded with "13 T26" plan. That is in effect what Jake1992 and I are proposing. The difference is to have a less expensive variant to allow RN to get the number of Frigates it needs within budget.. ...The proposal is to use the ...

...In my opinion the UK needs to build a vessel at a FTI/PPA equivalent price point that is better than the competition and the easiest way to do that is to start with the T26 hull.

Re: Current & Future Escorts - General Discussion

In other words, if the average sea going days per hull in 2010-2014 is kept, we need only 8.3 hulls in 2015-2018. More sensationally, current RN tasks can be covered with only 8.3 Type-23. It matches our impression that "deployed" escort number has decreased significantly these days. No A...

You are right. RN shall fight for "more money" and "more man power". But, the man-power "lost" from T23 = 840 amounts to "PoW crew". HMS Illustrious (650) and Ocean (285) were providing the other 800 crew for QNLZ (some 100 are lost elsewhere). QECV manpower &...

Now sell the rivers and T31, then build 20 multi mission ships. That's far more elegant. I hear talk about the need to 'rebalance' the RN's fleet, perhaps its correct, but at the moment the plan is swinging way to far to the low end. ?? Your "20 multi mission ships" are high end? At least...
