I do not know but may the high endurance Zephyr drones provide a similar facility. The electronics package is clearly far smaller but with modern electronics advancing wonder what its synthetic aperture radar performance would be?

Re: Queen Elizabeth Class Aircraft Carriers - News and Discussion

I believe the current QE flight deck is essentially the same parallel layout as CVA01 and seems much better than the angled deck for a "wide" carrier. Originally the outstanding advantage of the angled deck was that it left the front of the carrier to park aircraft while landing on without...

If I remember correctly the last single shaft frigate was the Type 14 Blackwood class. The other reference could be the US Oliver Perry, which is single shaft.

Re: F-35B Lightning II (RN & RAF)

I presume the 34 comes from the MoD statement that the design basis of the CVF was 36 JSF (+ helos). I believe that the Invincibles had a planeguard helo airbourne during launch and recovery. It is of interest that the design basis of the CVS/SHAR was for them to carry 5 (4 + 1 spare?) whereas in th...

Re: Ground Based Air Defence

Sorry for my ignorance but when is the "Land Ceptor" coming into service? It will be great to see the land forces regain a decent air defence system for the first time since Thunderbird's were withdrawn.

Alrosa, a Kilo class submarine of the russian northern fleet, uses a pump-jet but that does not seem to have continued with the most recent Kilo builds.

Re: Current & Future Escorts - General Discussion

Thought it was more obstructions to the cooling water intake for the reactor, hence why a ssk can sit on the bottom......? IIRC the biggest theoretical problem of sitting an SSN on the seabed was its completely round hull, with very real concerns about rolling. Certainly one of the safety concerns ...

You cannot compare the Baltic now to the 1980s. In those days East Germany, Poland, Lithuania, Estonia and Latvia were either part of the USSR or fully allied with it.

Re: AW159 Wildcat Helicopter (RN & AAC)

But given how many times Sea Skua has actually been used should be instructive. As far as I'm aware no combat use of Penguin,Sea Eagle ever, and no use of Maverick or Exocet from helos in combat. I may be wrong but I suspect that more Sea Skua missiles have been fired in anger than any other anti-s...

Re: Dreadnought Class SSBN

To my knowledge, the only SSN to have had its reactor changed was USS Seawolf in the 1950s. It was the second US nuclear submarine design and had a sodium cooled reactor, which was not a success, so it was removed (and dumped at sea) and replaced by a PWR. What was standard was the refuelling of sub...

Re: Current & Future Escorts - General Discussion

I may be reading the Sea Ceptor specs wrong but if it can achieve 25+km in anti-air mode it is logical that it could reach more than that in the surface mode (less terminal manoeuvrability required) and it has a low radar cross section (it is the same as ASRAAM, which has a low observability in exte...

Re: Queen Elizabeth Class Aircraft Carriers - News and Discussion

What is interesting is to compare the amount of undisturbed parking area on each design. By undisturbed I mean the are not affected by lifts, launch area and angled deck. I think that the QE has more space than a Nimitz, which would mean less a/c movements for a given tempo of activity. Looking at t...

In terms of weapons effectively used the "missile gap" is the Sea Skua vs. Sea Venom, and the need to get Sea Venom fitted to Merlins! A much more usefull weapon than Harpoon. :D

Re: Brimstone Missile (RAF)

If this Brimstone 2 integration happens it will be interesting in a naval environment. As I understand the missile range from a 50k ft launch should be 40-60km? So if a naval unit cannot engage 50k ft target at 50km it will be vunerable to a salvo of 12 missiles. Interesting? :D

Re: Queen Elizabeth Class Aircraft Carriers - News and Discussion

The RN policy of all a/c being stored in the hanger came from the 1930s when it was belived the way to handle air attacks on the carrier was to store all the a/c below the armoured flight deck and use the AA guns to fight off the attack. That was clearly a flawed view and rapidly revised during WW2....
