RAF Lockheed P-2 Neptune
 
Royal Air Force Coastal Command operated 50 odd P2V-5s, designated Neptune MR.1s as a stop-gap maritime patrol aircraft until the Avro Shackleton entered service. I understand they were used for Airborne Early Warning experiments as well as for maritime patrol.

My question ... How good was the Neptune as an AEW/MP platform as compared with the Shack ?

CS, I recall they were all held at RAF Silloth prior to being returned to the US. The P2V was in service with the RNlN in the 1970s. I guess it might have been quite good. As good as the Shack? I don't know.

Certainly better than no MPA...

Sorry, someone had to say it.

I expect they were quieter inside than the Shackletons!

Argentinian Neptunes
 
I believe the Neptunes were fitted with the APS-20, the same radar that was fitted to the Shackleton AEW Mk 2s.

As to how good the Neptunes were in comparison the the Shackletons, I reckon it was all down to the quality of the operator, as I am sure Pontious & Wenslydale will probably confirm.

During the Falklands conflict the ex-RAF Neptunes which were operated by the Argentinians were used to try to find our Task Force but I do not think they wre used in the AEW role.

CC, provided they were squawking or had 4 contra-rotating turbo props the Shack was the bees knees. Best I had was a pickup at 200 miles and lost contact some hours later at 225.

4 contra-rotating turbo props
- I assume that's a typo :O . I flew a number of times with the Cloggies in their P2's - thoroughly enjoyed it, and yes it was much quieter than a Shack. She was pretty quick a low level too ....

Pontius Navigator 29th Dec 2012 09:54

Reynolds, at 200 miles? No they were definitely huge turbo props :}

Towards the end of their life one was doing an air display, possibly at Den Helder, when at approaching 300 kts (I was told) the co-pilot's hatch lifted. The senior officer in the co's seat grabbed it and hung on but I believe the pressure blew the tail cone off.

Not sure how true but a good yarn.

I have also seen a Shack doing 300 kts over the salt lake at Akrotiri. It was trialling the rear crew parachute explosive drogue deployment. I believe it worked but the risk of a live drogue gun in the cabin was assessed as too high.

I took this photo at Biggin Hill during the 1954 Royal Observer Corps "Recognition Day". It shows RAF Neptune MR1 WX547 from the Fighter Command Vanguard Flight (1453 Flight) based at Topcliffe in Yorkshire.

Vanguard Flight Neptunes carried out some of the initial Airborne Early Warning Radar trials over the North Sea, but acording to Google they were not a success (see quote below).


By the 1950's, the Royal Navy and RAF had started the development of AEW systems. The Royal Navy ordered the development of an AEW Fairey Gannet, whilst using the AN/APS 20 radar equipped Douglas Skyraider from the US as a stopgap, and the RAF set up the "Vanguard Flight", also known as 1453 Flight, equipped with Lockheed P2V-5 Neptune's. They were not a success, and the flight was disbanded after 3 years. Therefore, the only operational AEW systems in use by the British armed forces up until 1970 were operated by the Royal Navy.

Fairly sure there was an ex RAF Neptune for sale in the States a couple of years ago. Owner was hoping that someone in the UK would buy it and put in on the airshow circuit. Not aware of what happened after that though. Any ideas?

CoffmanStarter 29th Dec 2012 13:04

Thanks Chaps ... all good stuff ... much appreciated :ok:

I guess it goes to show how important the British Aircraft Industry was in our economic recovery post WII.

On paper two broadly similar platforms in terms of performance ...

Neptune Vmo 278 Kts, Op Range 1912 NM's - Shack Vmo 260 Kts, Op Range 1950 NM's.

It could be argued that the Neptune could have been more than a "stopgap" solution until the Shack entered service with the RAF. In pure financial terms buying "off the shelf fit for purpose" Neptunes would have been the cold hearted sensible option ... but yet the 188 Shaks built by Avro, along with other post war British aircraft designs, provided much needed employment.

If we discount the macro economic argument for a moment ... it would be really good to hear from anyone who has flown both types to get their perspective on both platforms.

It's interesting to speculate that had we gone down the Neptune route the RAF could well have taken the P-3 Orion for the maratime role. I know we then get in to the Nimrod debate following the commercial export failure of the Comet.


Best regards ... and Happy New Year !

Where did the money come from for all this?

188 Shackletons? That's rather a lot of 27L V12 engines burning a boatload of (highly refined) gas.

There must have been a couple of thousand aircrew for that many aircraft, not to mention airfields and all the support infrastructure.

Shacks were contemporaneous with V-Bombers, Canberras, Hunters etc, of which there was a thousand or more.

The RAF's budget must have been ridiculous in those days. Same for the Royal Navy with a dozen or more capital ships and escorts aplenty, not to mention the FAA.

KING6024 29th Dec 2012 15:53

I can remember a Neptune at Bovingdon sometime in the mid 1950s,Shackletons were occasional visitors also,as Northwood was the Coastal Command HQ in those days, I guess Bovingdon was used as a communications airfield.Did Coastal Command have its own Communications Flight? The Metropolitan Comm. Flight was based at Bovingdon in those days.

Roadster, in the early sixties it was said the V-bomber cost £1M. It was our most expensive aircraft. Accounting for inflation that is now less than £40 MILLIONS. Now I don't know how much the Defence vote has increased in that time.

I do recall around 1971 a VSO, possibly AMP, was appalled that the RAF Manpower bill accounted for over half the RAF Vote. Which is more important? Could you draw an arbitrary division between manpower and equipment?

Of course not long after we were shedding lots of transport crews -Beverly, Argosy, Britannia, Comet, and then Canberra.

Gibson's new book "Battle Flight" might be of interest.

CoffmanStarter 29th Dec 2012 17:51

I understand that of the 188 Shacks built only 8 were exported to South Africa ... so thats a lot of metal built for the RAF ?

CoffmanStarter 29th Dec 2012 18:01

Not forgetting that a Mk4 Shack was proposed ...

Yeah but, no but, yeah but.........
 
......in those days there were Shack squadrons in Changi, Aden,Malta,Gibraltar. 3x squadrons at Bally kelly plus ASWDU, 3x sqadrons at Kinloss plus MOTU, and 2 squadrons at St Mawgan. Approx 15 basic crews of 10 men each plus execs and assorted gash bodies; plus all the groundcrew (until centralised servicing came in) and you're well on the way to your 2000 bodies. T'was a different world then, innit.

Just to chip in, 20 V-bomber sqns would have about 2000 aircrew not including station, groups and command staffs. I would guess the other flying commands and air forces would have had similar numbers.

In 1961, not counting the small number of aircrew at Cranwell, the initial aircrew officer training intake was around 100 per month of which around 80 were pilots.

Given chop rates and deaths and assuming aircrew on 8 year commissions (some were on 5, others leaving at 12, 16 and 20) there would have been about 6,000 - 7,000 into productive service at that time. Aircrew above JOs were either wartime assimilated aircrew or Cranwell output.

When a Nav course graduated in 1991 they were told the RAF aircrew requirement was just 1,000.
