Re: river I/I.5 and II patrol vessels
I may be seen as slightly optimistic, but given the supposed simplicity of its integration and fire control, if the OPVs had two quad packs of Sea Ceptor glued to the superstructure it would give them a potential impact that little else could achieve so cheaply. If I understand the claimed performan...

Re: Future 'Lighter' Frigate
In the original post second world war number system the type 12 and following numbers were ASW frigates, the type 41s were the air defence frigates (type 41 was the Cat class with 2 Mk6 4.5" turrents and hence the type 42 and so on to the type 45), the type 61 were the radar picket frigates wit...

Re: Type 45 Destroyer (Daring Class) (RN)
The WR21 gas turbine uses a Breyton cycle that promises the same efficiency as a combined cycle gas turbine design using precoolers, intercoolers and recuperator. It is more complex than a standard open cycle gas turbine, and in the case of the WR21 does not appeared to have been as good as hoped. I...

Re: UK's Future T26 Frigate.
Perhaps I am showing my age, but I served on Devonshire in the early 1970s and it was 6200 tons. That included a massive missile system (Seaslug) that had a magazine that was 250ft long, a large helicopter (Wessex), two short range missile systems (Seacat) and two 4.5 gun systems. That was seen to b...

Re: Her Majesty's Yacht Britannia (1954-1997) (RN)
Good grief, that brings back memories. The Queen came to Dartmouth in 1972 to attend the Lord High Admiral's parade, as that was her RN title at the time (I think she has passed it to the Duke of Edinburgh since then?). I was one of the Officer Cadets passing out from our time at Dartmouth and (besi...

Re: Type 45 Destroyer (Daring Class) (RN)
I suspect the real T45 propulsion problem is poor low power performance of the WR21 intercoled, recuperated cycle (a Breyton cycle). The intention was that it should operate through a much wider power range than previous GTs and this may have not worked out. So the T45s are like an old Tyne/Olympus ...

Re: Ocean Class Helicopter Carrier (LPH) (RN)
The level of accomodation is also a function of the accomodation standards. When I was on HMS Tenby in 1972 with hammocks (double slung) we got 40 of us in one messdeck! I suspecg that if there was a Falklands II one could overload QE by at least 500 over the design figure. I must point out that in ...

Re: Ocean Class Helicopter Carrier (LPH) (RN)
I suggest that people are fogetting the changes (in this thread) over the last 18months. We were talking about whether the second QE would be sold, scrapped or put in deep reserve. Now the RN is going to have them both manned, with each having a deployable F35 squadron, by 2023. To achieve this the ...

Re: Queen Elizabeth Class Aircraft Carriers - News and Discussion
Looking at the two deck plans it is noticable how much of the deck is available for parked aircraft that do not have to be repositioned during a launch/recover cycle. It looks to me as though the CVF STOVL layout leads to much less aircraft movements for a fully loaded carrier. Am I missing something?

Re: Queen Elizabeth Class Aircraft Carriers - News and Discussion
How many V22s would be needed for COD on QE & PoW? I suspect that 2 or 3 would be adequate and that might be viable if the UK had the same arrangement as the Airseeker. Using US based support and training facilities but with RN/RAF flight crew?

Re: Boeing P-8A Poseidon (Future Maritime Patrol Aircraft) (RAF)
As I understand the Indians have added a MAD boom. That and the integration of the Stingray torpedo in place of the Mk54 is all that should be sensibly considered.

Re: Queen Elizabeth Class Aircraft Carriers - News and Discussion
The original name for the Churchill class SSNs was to be the 'S' class following on from the 'R' class (Resolution class) but when Churchill died the class was renamed to honour him. The 'S' class (Swiftsure) then followed.

Is this not a function of crew numbers. In 2018 PoW will be needing its crew, about the same number as Ocean will release?

Re: Queen Elizabeth Class Aircraft Carriers - News and Discussion
If one of the QEs is enharnced for amphibious function it would imply that both are normally deployable as part of a surge, otherwise they would enharnce both of them?

The 196 is the rounds in the fully automatic system. Could there be a larger manual transfer system as well? On the 4.5 Mk8 there are a number of rounds that can be fired before the gun crew are mobilised. Is the 196 rounds merely an extension to that number? IIRC the older RN type 12s and County Cl...

Re: UK MoD To Acquire High-Flying Zephyr 8 UAVs
Two thoughts.
1. Could it carry a synthetic aperture radar? Some are very small.
2. Could it provide some kind of coverage to support the QE? Three months on station?
