Spitfire XVI

 

When the Type 224 performance proved disappointing, R. J. Mitchell was given a free hand to design a new single-seat fighter unfettered by official specifications. Mitchell outlined the Type 300 tailored around the new Rolls-Royce P.V.12 (Merlin) engine. With drag-reducing retractable landing gear, the wings were of distinctive elliptical shape, but they housed eight machine-guns, all of them firing outside the propeller disc. Air Ministry Specification F.36/34 was drawn up around the Type 300 and a prototype was ordered. It was powered by a 738kW Rolls-Royce Merlin C and flew for the first time on 5 March 1936. Comparatively little flight testing was needed to confirm its superb handling qualities and performance resulted in a first contract (for 310 Spitfire Mk I aircraft) being awarded on 3 June 1936. The crowds at the 1936 RAF Display at Hendon had a first glimpse of the prototype Spitfire in the New Types Park.

Structurally the Spitfire was a straightforward design with a light alloy monocoque fuselage and a single spar wing with stressed-skin covering and fabric-covered control surfaces. To preserve the clean nose-cowling lines originally conceived by Mitchell, the radiator was located beneath the starboard wing with the smaller oil cooler causing some asymmetry beneath the port wing, and the carburetor air intake under the center fuselage. A DeHavilland two-blade wooden fixed-pitch propeller was employed by the prototype and the first Spitfire I's had the Airscrew Company's wooden fixed-pitch two-blade. Later a DeHavilland three-blade, two position propeller was adopted after trials on the first prototype. The new propeller gave a 5 mph increase in speed. In 1940 DeHavilland three-blade constant-speed propeller were substituted. Production Spitfires had a fixed tail wheel and triple ejector exhaust manifolds. The X80 HP Rolls-Royce Merlin II and later the Merlin III engine was installed.

Deliveries of production Spitfire I's began in June 1938, two years after the first production contract had been placed. In those two years Supermarine laid out their Woolston factory for large-scale production and organized one of the largest subcontract schemes ever envisaged in Britain. Until that time, as it was becoming increasingly obvious that there was no limit to the likely demand for the Spitfire. It was also obvious that one factory alone was not going to be able to meet the demand even with sub-contracting. Large scale plans were laid during 1937 for the construction by the Nuffield Group of a large new shadow factory at Castle Bromwich near Birmingham for Spitfire production. On April 12,1938 a contract was placed for 1,000 Spitfires to be built at this new factory, of which the actual construction had not then even begun. In the following year, on April 29 further contracts were placed with Supermarine for 200 Spitfires and on August 9 for 450. When Britain went to war on September 3,1939 a total of 2,160 Spitfires were already on order.

It was not until July 1938 that the first Spitfire Mk I reached No. 19 Squadron at Duxford. Only five had been delivered by the time of the Munich crisis in September of that year.

The Spitfire I weighed 5,280 lb. had a wing loading of 24 lb/s. ft. and a fuel capacity of 85 Imperial gallons. Its maximum speed was 362 mph its maximum diving speed was 450 mph its initial climb rate was 2,500 ft./min. and it took 9.4 minutes to climb to 20,000 feet. Its combat range was 395 miles and its roll rate was 140 deg./sec. Standard armament in what was subsequently to become known as the A wing was eight 0.303-in. Browning machine-guns with 300 rounds of ammunition. The speed of the Spitfire I was marginally higher than that of its principal opponent the Luftwaffes Messerschmitt Bf 109E and it was infinitely more maneuverable than the German fighter although the Bf 109E could out climb and out dive the British fighter and its shell-firing cannon had a longer range than the Spitfire's machine-guns.

By the outbreak of war on 3 September 1939, the RAF had received 306 aircraft, 187 were distributed to operational squadrons, 36 had been written off and the balance went to the training units. The RAF had nine operational Spitfire squadrons, 1/3rd of Fighter Command Squadrons, and on 16 October 1939 a Spitfire of No. 603 Squadron claimed the first German aircraft to be destroyed over the UK in World War II, a Heinkel He 111. By August 1940, shortly before the Battle of Britain reached its climax, RAF Fighter Command could call upon 19 Spitfire Mk I squadrons.

The 1,175 hp Merlin XII was adopted as the standard power plant in the Type 329 Spitfire II with a Rotol three-blade propeller and 73 lb of amour protection, but this variant was otherwise similar to the Spitfire I. Deliveries commenced in 1940, the Spitfire II having followed the Mark I on the production lines and becoming the first major production variant to be delivered from Castle Bromwich.

By December 1940 Spitfire Mk IIs were carrying out 'Rhubarb' sweeps over occupied Europe.

During 1940 the Spitfire MkI and MkII barely maintained superiority over the Messerschmitt Bf109E so the Air Staff turned their attention to the question of a replacement. Their preferred successor was the MkIII, fitted with a Merlin XX engine and incorporating a new wing design.

Realising it would take time to tool up for a new production aircraft and because of problems with the Merlin XX, the Air Ministry asked Rolls-Royce, as an interim measure, to install the Merlin 45 engine in the Spitfire Mk I airframe. Between 1941 and 1943 over 6500 of this Type 349 MkV version were produced. The spitfire Mk III never did go into production but some of the new design features intended for it were incorporated into the MkV. 

 

Spitfire-5B
Supermarine Spitfire Mk.Vb


The Spitfire MkV was one of the most successful 'stop-gaps' ever introduced into Royal Air Force Service. Over one hundred and forty RAF squadrons operated the type. It served on all battlefronts and was supplied to nine other countries including the Soviet Union and the United States.

By 1944 only five squadrons remained in service. Even so, two Spitfire MkV squadrons provided gunfire direction on 6 June 1944 for naval units off the D-Day beached of Normandy.

The first squadron to fly the Spitfire V was the No. 92 and in March 1942, fifteen Spitfire VBs which had been shipped to Malta on H.M.S. Eagle, became the first Spitfires to serve outside Europe. Spitfires of this Mark were later to serve in the Western Desert and the Pacific by early 1943 and Burma areas.

In the normal course of development, means were sought to increase the altitude performance of the Spitfire which was inferior to that of the Messerschmitt Bf 109E . This called for two principal modifications, the introduction of a pressurized cabin and the use of an engine suitably rated for higher altitude. The first version of the Spitfire so equipped was the Mark VI derived directly from the Mark VB as a result of work on pressure cabins at the Royal Aircraft Establishment and Supermarine during 1940-41. At the R.A.E., R7120 was fitted with a Merlin 47 (the high rated version of the Merlin 45) with a four-blade Rotol propeller with Jablo blades and a pressure cabin. The same engine was employed by the 100 Spitfire VI (Type 350) fighters built by Supermarine the first two of these AB176 and X4942 serving as prototypes. The production Spitfire VI also had an increase in wing area to improve controllability at high altitudes the wing being of pointed planform with a span of 40 ft. 2 in. The pressure cabin was contained between the bulkheads fore and aft of the cockpit and a special non-sliding hood was fitted to simplify the sealing problem. A Marshall blower provided a cabin differential of 2 lb./s. in. reducing apparent altitude from 40,000 feet to 28,000 feet. In other respects including armament the Spitfire VI was similar to the Mark VB.

The Spitfire VII high-altitude fighter evolved from Supermarine Spitfire VC with pressurized cockpit, sliding hood, increased fuel capacity, retractable tail wheel, two-stage, two-speed 1,565 hp Merlin 61 or 1,710 hp Merlin 64 (in Supermarine Spitfire F Mk VII) or 1,475 hp high-altitude Merlin 71 (Supermarine Spitfire HF Mk VII). Extended wing-tips usually fitted and, later aircraft, broad-chord rudder with extended tip. Prototype conversions of Mk VCs flown second half of 1942; 140 produced by Supermarine, first deliveries September 1942 and operations began same month. One Mk VII to USAAF at Wright Field in April 1943.

The Spitfire VII (Type 351) was a more extensive re-design for high-altitude work and was the first of the Spitfire series intended to make use of the two speed Merlin 60 series of engines. These two-stage engines were coupled with a re-designed cooling system which showed itself in the enlarged air intake under the port wing matching that to starboard. The wing outline remained similar to that of the Spitfire VI but the ailerons were reduced in span. The chord and area of the rudder were increased and the elevator horn balance was extended. Structural changes were made to the fuselage to take the increased engine loads and a double-glaze sliding hood was fitted to the cockpit. The retractable tail wheel first developed for the Spitfire III was applied in production for the first time on the Mark VII and the universal C -type wing was employed. Maximum speed jumped by 44 m.p.h. to 408 m.p.h. and normal loaded weight climbed to 7,875 lb.

1652 Spitfire Mk VIII variants were built.

Spitfire VIII


The Mk.IX had been a quick lash-up of the MK.V to get the 60s series of Merlins into action in 1942. There were a number of minor strengthening modifications enroute, but it was still basically the same Spitfire as the Mk.I. The Mk.IX entered production in 1942. Despite a weight of 3.5 tonnes, the speed had jumped to 650km/h (405mph). About 5600 were built with British built Merlins and a further 1053 were fitted with American Packard V-1650 (Merlin 266) engines when these became available in 1943. Those Spitfires were known as LF Mk.XVI, largely for allocation to squadrons of the 2nd Tactical Air Force in 1944, with a 12 volt systems.

spit-9e
Spitfire IXe


The Mk.XVI (basically a Mk.9 with a Packard Merlin) was the final Merlin powered Spitfire, all later models were powered by the RR Griffon. The Packard Merlin 266 supercharger gear was electro-hydraulically operated rather then electro-pneumatically as with the RR Merlin 66 fitted to the Mk.IX.

 

Pilots who converted from the Merlin to the Griffon-engined Spitfires soon discovered that, because the Griffon engine's propeller rotated in the opposite direction to that of the Merlin, the fighter swung to the right on take-off rather than to the left. This tendency was even more marked with the more powerful 60 and 80 series Griffon engines, with their five-bladed propellers. As a result, pilots had to learn to apply left (port) trim on take-off, instead of the right (starboard) trim they were used to applying. On take-off, the throttle had to be opened slowly, as the pronounced swing to the right could lead to "crabbing" and severe tyre wear.

 

Some test Spitfire XIVs, 21s, and 24s were fitted with contra-rotating propellers, which eliminated the torque effect. Early problems with the complex gearbox that was required for contra-rotating propellers prevented them from ever becoming operational in Spitfires, but they were used on later aircraft including the Seafire FR. Mk 46 and F and FR.47, which were fitted with Griffon 87s driving contra-rotating propellers as standard equipment. The Griffon 57 and 57A series, driving contra-rotating propellers, was used in the Avro Shackleton maritime patrol aircraft.

 

The prefix LF signified 32 ft 7 in (9.88m) clipped wings (shorter than the usual F by 1.35m). The LF clipped wing variant was faster and more agile at low level for the ground attack role.

A degree of multi-role capability was to result from the development of low-altitude clipped wings (prefix LF), and high-altitude increased-span wings (HF), the standard wing being identified as F, and with variations of armament within these wings comprising eight machine-guns (suffix A), two cannon and four machine-guns (B), four cannon (C) and two cannon, two 12.7mm machine-guns and up to 454kg of bombs (E).

Spitfire LF Mk XVIE; The "E" status indicated the armament, two 20mm Hispano cannon and two 0.5 Browning machine guns.

In November 1939 Supermarine allocated Type 337 for a feasibility study of a Griffon engined Spitfire.

The FR.XIV was a redesigned and strengthened airframe for the 2050 Griffon 65 or 66 with a five blade prop, broad tail and tear drop canopy.

The Spitfire XIX reconnaissance version became the fastest of all the wartime Spitfires with a speed of nearly 748 km/h (460 mph).

The Mk.21 featured a stronger wing to carry two cannon in each wing, and a new, strengthened, fuselage and tail unit. The Mk.21 first flew in 1943 and entered production in 1944.

The last major production Spitfire was the F22. The F24 differed only in the smallest of details and some F24s were converted from F22 airframes. The Spitfire F24 was the ultimate development of the type, but the advent of the jet fighter meant that only small numbers were built and even fewer went into Royal Air Force service. Only seventy F24s were completed and most went into store although No.80 Squadron was fully equipped with the type.

These examples of the Spitfire incorporated all the modifications and improvements developed on earlier marks. The F24s had a tear-drop canopy for greater visibility and enlarged tail surfaces for better control. Like many of the later marks the F24 was fitted with the more powerful Griffon engine which provided a 160kph (100mph) greater top speed than the early Spitfires and almost twice the rate of climb. The weight of firepower from its cannon had tripled over the types' original fit of eight machineguns.

With the war nearly over only 350 Mk.21s, 22s and 24s were built of the 3000 or so ordered. The last Spitfire was built in 1947.

Spitfire Tr.IX

 

The Seafire (abbreviated from the original name ‘Sea Spitfire’) gave the Royal Navy (RN) a carrier-based air superiority fighter aircraft in WW2. As a direct development of the Spitfire, it suffered from a short range, but its fast climb and agility made it an effective fleet defence fighter and Seafire squadrons served in the Mediterranean, on D-Day and against the Japanese in the Pacific.

 

Interest in the idea of a carrier-borne Spitfire first surfaced in the late 1930s and Supermarine’s Chief Designer, Joseph Smith, had an ‘A-frame’ arrestor hook fitted on a Spitfire. This flew on 16 October 1939 as the type Type 338. Supermarine proposed a Spitfire design to the Fleet Air Arm (FAA) with the arrestor hook and with wings that swivelled and folded back, and in February 1940 the Admiralty requested the production of fifty of these but the First Lord of the Admiralty, Winston Churchill, intervened and the order was and cancelled.

 

Churchill regarded the production of Fulmars vital and the greater need for land Spitfires, the diversion of resources to a new navalised variant would reduce Spitfire’s production numbers.

 

The first Sea Spitfires were simply existing examples (Mk.Vb) with some naval equipment added (hook and catapult spools, as well as Naval instruments and radios) but without major modifications such as folding wings. However when the Seafire began operations, it was quickly found that the fuselage of these modified Spitfires was too weak for carrier operations. Reinforcing strips were riveted around hatch openings and along the main fuselage longerons to alleviate these issues. This was the Seafire Mk Ib, becoming the first of several Seafire variants to reach the FAA. Catapult and deck trails began early in 1942, and in the spring, contracts were placed to convert 116 Spitfire Mk.Vb into Seafire Mk.Ib examples. The Seafire IIc followed this. Although of similar configuration, it was purposely re-designed for naval use. To follow was the Mk.III, which was also the first to use (manually) folding wings, and this became the final version to see WW2 service. The Seafire L.III was based on the Spitfire Mk.VC.

 

Because of the small size of the carriers, and the harder landing-on techniques, it was found that approaches were difficult, visibility was limited, landing gear collapses were commonplace, and the arrester hooks had a tendency to miss and bounce back into the fuselage with the inevitable resultant collision with the deck park or barrier. As a low-level fleet defence interceptor, the Seafire was supreme, but its fragility was its Achilles heal. More were lost to landing gear failures in hard landings than to enemy action.

 

First entering service with No 807 Squadron in mid-1942 and going to sea on board HMS Furious.

 

After initial placement on the Russian convoy routes, the FAA’s Seafires saw the majority of their action in the Pacific campaigns. Due to their good high altitude performance (and lack of ordnance-carrying capability) the Seafires were allocated the Combat Air Patrol (CAP) defensive duties. Flying over the fleet, they were heavily involved in countering the Kamikaze attacks during the Iwo Jima landings and beyond.

Seafire XV


A total of 20,334 Spitfires and 2,556 related new-build Seafire naval fighters were built. It also had the distinction of remaining in production throughout the entire war and was operational post-war, the last mission flown by a photo-reconnaissance Spitfire PR.Mk 19 of No. 81 Squadron in Malaya on 1 April 1954.

 

Work on a more powerful Seafire with a Rolls Royce Griffon began during WW2, but the Mk.XV didn’t arrive in time to take part, but it was followed by a series of Griffon powered versions and these filled the gap before the arrival of Hawker’s Sea Fury. With a bubble canopy and upgraded undercarriage, the Seafire XVII was an improved version of the XV. 

 

Then the Seafire Mk.45 was the first version to be powered by a Griffon 60 series engine, but was a retrograde step in having fixed wings and it suffered from directional instability caused by engine torque.
 
Built by Vickers Armstrong at Castle Bromwich under contract B981687/39, the F Mk.46 Seafire started life as a part of the seventh order for 300 Spitfire Mk.Vc’s in March 1942. However, this contract was cancelled in 1943 but then later re-established as an order for 120 Spitfire Mk.21’s. This order was then further extended to inculde 94 Seafire F Mk.45’s and Mk.46’s.
To solve the torque problems, contra-rotating propellers were introduced on the Mk.46, but curiously, folding wings were not incorporated, and so it never saw front-line service. Seen as a “semi-navalised” variant of the Spitfire Mk.22, the Mk.46 Seafire was fitted with the bubble style canopy and the cut-down rear fuselage, which was seen earlier on the Mk.XVIII Seafire, but this new aircraft lacked the curved windscreen of the earlier aircraft. The previous Mk.45 Seafire was euipped to carry 120 gallons (454 litres) of fuel; added to this the Mk.46 was fitted with a 33 gallons (125 litres) fuel tank in the rear fuselage, also it could also will fitted with two 22½ gallon (84 litre) drop tanks under each wing. The power for the Mk.46 came from a Griffon 87 engine which was connected to a six-bladed Rotol contra-rotating propeller.  The double propeller system successfully counted the engine torque seen in the earlier Griffon engines. Also the Mk.46 was to be fitted with the enlarged tail section from the Spiteful airframe.

Seafire Mk.46
 
So with the combination of the contra-rotating propeller system and the new tail, this gave the aircraft greater stability, making it much easier to fly. The Mk.46 was fitted with a 24 volt electrical system, unlike the Mk.45 which was just 12 volts. The both the Fighter and the Fighter-Reconnaissance variants of the Mk.46 were fully tropicalised and provision was made for deck landings with a “string” type arrester hook. However, it was planned that this variant would be only used from shore bases.
The prototype, TM383, was in fact a Mk.21 Spitfire airframe modified by Cunliffe-Owen and first flew on the 8th September 1944. This aircraft was scheduled as the third prototype for the Mk.45, but was withdrawn from that contract for use on the Mk.46 trials. By January 1945 was well into its prototype trials. It was stated that during one of the trails “Dived in formation with LA436 (a Mk.45) at 495 knots LA436 was going steeper and accelerating but vibration on TM383 became such that it was eased out of the dive”.
 
The FR Mk.46 only differed by having the provisions for a pair of F.24 aerial cameras to be fitted in the rear fuselage, one in the vertical and the other in oblique positions. To stop mud and dirt covering the vertical camera port during take-off, a “mud-flap” was fitted over the port and was jettisoned by the pilot once airborne. Both aircraft variants were also fitted with a cine-camera mounted in the leading edge of the starboard wing.
 
The Mk.46 was armed with 4 x 20mm Mk.II cannons and with its strengthened wings it could carry either 8 x 25lb or 60lb head rocket projectiles and mounted uder the fuselage it could carry 1 x 250lb or 500lb bomb.
 
Only 24 Seafire Mk.46’s were to be finally produced and they carried the serial numbers LA541 to LA564. Entering into service in 1948, the Mk.46 was seen as an interim aircraft and as such it was not to see front fline service and was only used in the training role by Nos. 736, 738, 767, 771, 777, 778, 781 and 787 Naval Air Squadrons. Later a number of these aircraft were also to see service with various trials organisations. One airframe LA544 was used on anti-spin trials in 1946 and as such was fitted with an anti-spin parachute and fin guard.
 
Before the Mk.46 was retired from service in 1951, the last of the F Mk.46’s were operated by No. 1832 RNVR Squadron.
The final version, the Mk.47, with the addition of folding wings, was actually suitable for carrier operations and saw combat in Malaya and in the early campaigns of the Korean War. Eventually over 2,000 Seafires were produced, 1,200 RR Merlin powered and 800 RR Griffon powered.
