somehow i have myself a mini theam starting here the royal navy during the korean war.
i have the boeing f8 shearwater as a fighter-bomber and a jet fighter in the shape of the westland wyvern fited with a aj-65 avon engine,
now i am looking for ideas for a helicopter, as plane guard, and troop transport, a COD aircraft.
these must fit on a  aircraft carrier of the Malta Class
The Maltas were designed with the strike role in mind, as British carriers in service at the time were unable to field the same quantity of aircraft, or launch and recover them at similar rates, to carriers of the United States Navy. The ships were designed along similar lines to the American Midway-class aircraft carriers, and were to be slightly larger at 897 feet (273 m) in length overall and 115 feet 9 inches (35.28 m) at the beam. It was predicted that each ship would displace 47,350 tonnes at standard load, and 56,800 tonnes at full load, with draughts of 29 feet 6 inches (8.99 m) and 34 feet 6 inches (10.52 m) respectively. Eight boilers and geared steam turbines would have supplied 200,000 shp (150,000 kW) for propulsion; this was to be distributed to five propeller shafts (the thinking was that a fifth, centerline shaft would have been less susceptible to damage from torpedoes).
There were major design departures from previous British carriers, with an open hangar deck, allowing aircraft to warm up their engines before transferring to the flight deck for launch. The 897-by-136-foot (273 by 41 m) flight deck allowed multiple aircraft to launch or land simultaneously, and four aircraft lifts (two on the centereline, and two on the deck edges) aided the rapid movement of aircraft around the flight deck.Sixteen arrestor cables would have been capable of catching landing aircraft up to 20,000 pounds (9,100 kg) in weight, at speeds of up to 75 knots (139 km/h; 86 mph), while the two hydraulic aircraft catapults could launch fully laden aircraft at 130 knots (240 km/h; 150 mph). The armoured flight deck, while seen as a necessity in the context of Japanese kamikaze attacks, was, at 4 inches (100 mm), thinner than other British carriers.[1] Between the hangar spaces and the deck park, the Malta class design would have been capable of carrying up to 80 aircraft.

An Avon engined Wyvern? The mind BOGGLES!  :o
Kit's Rule 1 ) Any aircraft can be improved by fitting longer wings, and/or a longer fuselage
Kit's Rule 2) The backstory can always be changed to suit the model

...and I'm not a closeted 'Take That' fan, I'm a REAL fan! :)

its not the lightning engine, it what became the engine,
The Avon design team was headed by Cyril Lovesey, who had previously been in charge of Merlin development.
The engine was intended both as an experiment in axial-flow engines, as well as (if successful) a replacement for the 5,000 lbf (22 kN) Nene.
Originally known as the AJ.65 for Axial Jet, 6,500 lbf which was originally designed by Alan Arnold Griffith, the engine developed as a single-spool design with an eight, later 10 stage compressor, mass flow rate of 150 lb/s (68 kg/s) and a pressure ratio of 7.45.
Development started in 1945 and the first prototypes were built in 1947.
Introduction was somewhat slowed by a number of minor problems.
The first Avons to fly were two Avon RA.2s in the converted Lancastrian military serial VM732, which flew from Hucknall on August 15, 1948.
Initially a private venture for the company, government backing was forthcoming around the time of the first prototypes.[3]
The modifications and improvements introduced to the Avon 200 series were considerable, resulting in a completely different engine with very little in common with the early Marks.
Despite this, the name Avon was retained.
Differences included a completely new combustion section, a 15 stage compressor based on that of the Armstrong-Siddeley Sapphire, as well as other improvements.
The engine eventually entered production in 1950, the original RA.3/Mk.101 version providing 6,500 lbf (29 kN) thrust in the English Electric Canberra B.2.Similar versions were used in the Canberra B.6, Hawker Hunter and Supermarine Swift.
Uprated versions soon followed, the RA.7/Mk.114 producing 7,350 lbf (32,700 N) in the de Havilland Comet C.2, the RA.14/Mk.201 of 9,500 lbf (42 kN) in the Vickers Valiant and the RA.26 of 10,000 lbf (44 kN) used in the Comet C.3 and Hawker Hunter F.6.
An Avon-powered de Havilland Comet 4 flew the first scheduled transatlantic jet service in 1958. The line eventually topped out with the 12,690 lbf (56,450 N) and 16,360 lbf (72,770 N) in afterburner RA.29 Mk.301/2 (RB.146) used in later versions of the English Electric Lightning.
Other aircraft to use the Avon included the de Havilland Sea Vixen and Fairey Delta.

The Avon was also produced under license by Svenska Flygmotor as the RA.3/Mk.109 as the RM5, and an uprated RA.29 as the RM6 with 17,110 lbf (76,110 N). The RM5 powered the Saab Lansen, while the RM6 was the main powerplant of the SAAB Draken.

Production was also carried out in Belgium by Fabrique Nationale, including 300 Avon 113s, and a larger number of Avon 203s.[4]

In the US, the Avon was used to power the vertical landing Ryan X-13 Vertijet aircraft (in RA.28-49 form).

In Australia, the Avon was used by Commonwealth Aircraft Corporation to power its heavily modified variant of the F-86 Sabre, known as the CA-27 Avon-Sabre.

The Avon continued production, mostly for the use in the Sud Aviation Caravelle and English Electric (BAC) Lightning, until 1974, by which time over 11,000 had been built. The engine garnered an impressive safety record over that time. The Avon was still in operational service with the RAF in the Canberra PR.9 until 23 June 2006.
