Messerschmitt Bf 109 E variant (''Emil'') single-engined fighters. Although the Spitfire had attracted more attention from the public, the Hurricanes were more numerous and were responsible for most of the German losses, especially in the early part of the battle. The turn-around time (re-arm and refuel) for the Spitfire was 26 minutes, while the Hurricane's was 9 minutes, which increased its effectiveness. Many of the Spitfires used in the battle were purchased privately. Money raised by towns, companies, clubs or individuals was used to buy Spitfires for £5,000 each with the purchaser having naming rights. Queen

made recommendations for the installation of "optically true" glass into the side panels to solve the problem. The Hurricane had a higher seating position, which gave the pilot a better view over the nose than the Spitfire. The upper canopy panels of the Bf 109 through its E-3 subtype were curved, while the E-4 and later ''Emil'' subtypes were modified for better visibility with flat panels and the new design was often retrofitted to earlier 109s.

, if the stick was pulled back too far on the Spitfire in a tight turn: During tight turns the "twist" or washout designed into the wing by Reginald Mitchell meant that the wing root would stall before the wingtips, creating the shuddering and clattering referred to. This noise was a form of stall warning, reminding the pilot to ease up on the turn. British testing in September 1940 revealed that some Bf 109 pilots succeeded in keeping on the tail of the Spitfire, despite the latter aircraft's superior turning performance, because a number of the Spitfire pilots failed to tighten up the turn sufficiently. The gentle stall and good control under "g" of the Bf 109 were of some importance, as they enabled the ''Luftwaffe pilot to get the most out of the aircraft in a circling dog-fight by flying very near the stall.

which automatically deployed prior to stalling, but also made it much more difficult to continue chasing either a Hurricane or Spitfire with a tight turn in aerial combat manoeuvres, from the slats intermittently opening in tight turns (on the wing to the "inside" of a turn) during dogfights, even causing problems during a takeoff if they opened unevenly.

) and dive away from an opponent as the 109 could, their engines would temporarily cut out for the duration of the negative-g forces. This ability to perform negative-g manoeuvres without the engine cutting out gave a 109 pilot better ability to disengage at will. On the question of comparative turning circles in combat, Spitfires and Hurricanes benefited from their lower wing loading compared with the Bf 109: the Royal Aircraft Establishment estimated the Spitfire's turning circle – without height loss – as 212 m (700 ft) in radius (the Hurricane's would be slightly tighter) while the 109E's was estimated as 270 m (890 ft) radius at 3,657 m (12,000 ft).Green 1980, p. 70. Other sources variously list a turn radius of between 125 m (410 ft) and 170 m (558 ft)at ground level and 230 m (754 ft) at 6,000 m (19,690 ft) for the 109E.''Baubeschreibung für das Flugzeugmuster Messerschmitt Me 109 mit DB 601'', 1939. Reprint: Luftfahrt-Archiv Hafner. The ''Emil'' was smaller than either RAF fighter, and it was more difficult to land and take off than the Spitfire and Hurricane. At high speeds controls tightened considerably, and the Bf 109E needed more strength to manoeuvre than either of its main opponents. Of all three fighters, the Bf 109E would possess the highest roll rate, with the aileron controls being brisk and responsive; the Spitfire had the highest aileron forces, but both the Spitfire and the Messerschmitt's rate of roll suffered at high speed. Overall the differences in performance between the Bf 109 and Spitfire were marginal and in combat they were surmounted by tactical considerations such as which side had seen the other first, which side had the advantage of altitude, numbers, pilot ability etc. with the main difference between the two aircraft being the Spitfire's tighter turning ability and the Bf 109's faster climb rate.Price 2002, p. 78.


Armament

Both RAF fighters were armed with eight

Browning machine guns in the wings, harmonised by the squadrons to allow the bullets to converge at a distance. The Brownings had a high rate of fire and even a short burst from the eight machine guns sent out a large number of bullets. Although efficient against many aircraft, the small calibre bullets were often unable to penetrate the armour plating which was being increasingly used in ''Luftwaffe'' aircraft to protect crew and vital areas. An incendiary round, called the "De Wilde" was available, and this could do more damage than the standard "ball" rounds. During the battle at least one Hurricane was experimentally armed with a single

in a pod under each wing although it proved to be too slow and sluggish on the controls to be effective. Several Spitfires, designated Spitfire Mk. IBs, were also modified to carry a Hispano cannon in each wing panel. 19 Squadron was equipped with this version in June 1940. On entering combat in August this first cannon armed Spitfire failed to create an impact, with the guns often jamming and unable to fire. When it did work, however, the Hispano was an effective weapon, with its shells easily able to penetrate the armour plating and self-sealing fuel tanks of ''Luftwaffe'' aircraft. The Emil's main armament depended on the subtype. The E-1 was armed with four

ammunition. Although the explosive shells had greater destructive power than the bullets of the Brownings, these cannon's low muzzle velocity and the limited ammunition capacity of their sixty-round drum magazines meant that the armament was not markedly superior to the RAF fighter's eight machine guns. Three or four hits from the cannons were usually enough to bring down an enemy fighter and, even if the fighter was able to return to base, it would often be written off. For example, on 18 August a brand new Spitfire of 602 Squadron was hit by 20 mm shells which exploded in the structure of the rear fuselage. Although the crippled aircraft was successfully landed back at its airfield it was subsequently deemed to be unrepairable. The MG FF/M, used in the Bf 109E-4, was modified to fire the more destructive, high-capacity mine-shells propelling the lighter shells at greater velocities than the MG FF.Williams and Gustin 2003, p. 23.Williams and Gustin 2003, p. 313. The early shells of this type had contact fusing, detonating on contact with the skin of the airframe rather than penetrating, then exploding. The more streamlined Bf 109 F-1, issued in small numbers starting in October, carried two cowl MG-17s and a single 20mm MG FF/M in the fuselage as an engine-mounted ''Motorkanone'', firing through the propeller hub.


Fuel tanks

A drawback of the Hurricane was the presence of a fuel tank just behind the engine firewall, which could catch fire and within a few seconds severely burn the pilot before he managed to bail out. This was later partly solved by fitting a layer of "Linatex" fire-resistant material to the tank, and an armoured panel forward of the instrument panel. Another hazard was presented by the main wing root mounted fuel tanks of the Hurricane, which were vulnerable to bullets fired from behind.Bungay 2000 The main fuel tanks of the Spitfire, which were mounted in the fuselage forward of the cockpit, were better protected than that of the Hurricane; the lower tank was self-sealing and a panel of 3 mm thick

, sufficient to deflect small calibre bullets, was wrapped externally over the top tanks. Internally they were coated with layers of "Linatex" and the cockpit bulkhead was fireproofed with a thick panel of asbestos.Price 1996, pp. 18–21. On all the German fighters and bombers, the fuel tanks were self-sealing, and although capable of sealing leaks from enemy rounds, this could not prevent possibly fatal damage being inflicted by the "De Wilde" incendiary round which was being used by the RAF.


German fighter fuel capacity

A much more serious issue for the Luftwaffe's single-engined fighter force during the Battle was the Bf 109E's limited fuel ''capacity'' as originally designed. The Bf 109E escorts had a limited fuel capacity resulting in only a 660 km (410 mile) maximum range solely on internal fuel, and when they arrived over a British target, had only 10 minutes of flying time before turning for home, leaving the bombers undefended by fighter escorts. Its eventual stablemate, the Focke-Wulf Fw 190A, was only flying in prototype form in the summer of 1940; the first 28 Fw 190A-0 service test examples were not delivered until November 1940. The Fw 190A-1 had a maximum range of 940 km (584 miles) on internal fuel, 40% greater than the Bf 109E. The Messerschmitt Bf 109E-7 corrected this deficiency by adding a ventral center-line ordnance rack to take either an SC 250 bomb for '' Jabo'' duties, or a standard 300 litre (66 Imp. gal/80 US gallon) capacity Luftwaffe

to double the range to 1,325 km (820 mi). The ordnance rack was not retrofitted to earlier Bf 109Es until October 1940.


Durability and armour

The Spitfire, from about mid-1940, had 73 pounds (33 kg) of armoured steel plating in the form of head (of 6.5 mm thickness) and back protection on the seat bulkhead (4.5 mm), and covering the forward face of the

header tank. The Hurricane had a similar armour layout to the Spitfire, and was the toughest and most durable of the three. Serviceability rates of Hawker's fighter were always higher than the complex and advanced Spitfire. The Hurricane featured extensive fabric covering rather than stressed-skin aluminium - this meant that unless an impacting bullet or shell hit a critical spar the projectile would simply pass straight through the airframe leaving two small holes which could easily be patched. The Messerschmitt Bf 109 E-3 received extra armour in late 1939, and this was supplemented with a 10 mm thick armoured plate behind the pilot's head during and after the Battle of France. Behind the fuel tank, an 8 mm armoured plate was placed in the fuselage protecting the tank and the pilot from attacks from behind.

's most successful aero engines, pressed for the introduction of 100 octane aviation fuel from the US, and later that year the British aero engine manufacturers Bristol and Rolls-Royce demonstrated variants of their 'Mercury' and 'Merlin' engines rated for 100 octane fuel. A memorandum by the "Department of Defence Co-Ordination", 'Proposals for securing adequate supplies of 100 octane fuel to meet war requirements', 23 December 1938, noted that there was a need to increase supplies of 100 octane fuel and discussed ways in which this could be achieved."Proposals for securing adequate supplies of 100 octane fuel to meet war requirements."
''naa12.naa.gov.au''. Retrieved: 2 January 2010.
A meeting was held on 16 March 1939 to consider the question of when the 100 octane fuel should be introduced to general use for all RAF aircraft, and what squadrons, number and type, were to be supplied. The decision taken was that there would be an initial delivery to 16 fighter and two twin-engined bomber squadrons by September 1940. However, this was based on a pre-war assumption that US supplies would be denied to Britain in wartime, which would limit the numbers of front-line units able to use the fuel. On the outbreak of war this problem disappeared; production of the new fuel in the US, and in other parts of the world, increased more quickly than expected with the adoption of new refining techniques. As a result, 100 octane fuel was able to be issued to all front-line Fighter Command aircraft starting in the spring of 1940. Although U-boats and surface raiders had begun to take a heavy toll of tankers, in the summer of 1940 there was a surplus of these ships because of the incorporation into the British merchant marine of tanker fleets from countries overrun by Germany. The combination of CS propellers and 100 octane fuel put the British fighters on par with the Luftwaffe.Morgan and Shacklady 2000, pp. 55–56. Throughout 1940 the supply situation and distribution of the fuel to the front line services was discussed by the "Co-ordination of Oil Policy Committee". With 100 octane fuel the supercharger of the Merlin III engine could be "boosted" to +12 lbs/sq.in., producing 1,310 hp (977 kW) at 3,000 rpm at 9,000 feet (2,743 m) with a time limit of five minutes. This increased power substantially improved the rate of climb, especially at low to medium altitudes, and increased the top speed by 25–34 mph up to 10,000 feet. During the Battle of France and over Dunkirk RAF Hurricanes and Spitfires were able to use the emergency boost. "In the first half of 1940 the RAF transferred all Hurricane and Spitfire squadrons to 100 octane fuel." In the opinion of a pre-war paper by the British Air Ministry, Germany, as a large producer of synthetic fuel, was thought to be in a favourable position to produce 100 octane fuel in large quantities. The German supply of aviation fuels was largely based on the

long range "destroyer" (German: ''Zerstörer'') was expected to engage in air-to-air combat while escorting the ''Luftwaffe'' bomber fleet. Although the aircraft was well designed and the best of its class, being reasonably fast (Bf 110C-3 about 340 mph 47 km/h and possessing a respectable combat radius, the concept that the Bf 110 could defend bombers against a concerted attack by a force of fast single-seat, single-engined fighters was flawed. When pitted against the Hurricane and Spitfire the Bf 110s began to experience heavy losses through being only slightly more manoeuvrable than the bombers they were meant to escort and suffering from poor acceleration. A variant of the 110 was the Bf 110D-1, nicknamed " Dachshund-belly" (''Dackelbauch'') because of the fixed, wooden, 1,050 litre (277 U.S. gal) fuel tank fitted under the fuselage. I./ZG 76, based in Norway, was equipped with this version in order to provide air cover for convoys sailing along the Norwegian coast. On 15 August, in the belief that all of the RAF fighter units were concentrated far to the south, ''Luftflotte 5'' launched its first and only bomber attack against North Eastern England. Seven out of the 21 I.ZG 76 aircraft being used as bomber escorts were destroyed, including that of the '' Gruppenkommandeur'' ("Group Commander"). The casualty rates for all of the ''Zerstörergeschwader'' wings using the Bf 110Cs were extremely high throughout the battle, and they were unable to fulfill the high aspirations of Hermann Göring, who had referred to them as his "Ironsides" (''Eisenseiten'')."Weal 1999, pp. 42–51.

. This aircraft was intended to be used as a "bomber destroyer" because it was thought: However, between the medium bomber types used by the Luftwaffe — the Do 17Z, the He 111P & H, and the Ju 88A, none of these had a manned tail-gunner's position ''in'' the rear fuselage as part of their designs, as used during the Battle. By 1940, it was clear to both the RAF and the ''Luftwaffe'' that the deadliest opponents of bombers were single-engine, single-seat fighters with fixed, forward firing armament. Apart from the extra weight and drag imposed by the four-gun turret and second crew member, the Defiant lacked any directly forward-firing armament. Should the gunner need to escape from the turret in an emergency, the only way he could do this was to traverse the turret to one side and bail out through the escape hatch — but if the aircraft's electric system was disabled, immobilizing the all-electric turret due to its power source being knocked out, there was no escape. After the strong intervention of Dowding, who realised the Defiant was designed to an unworkable concept, there were only two units equipped with this aircraft,

''). They only made one mission during the battle itself when on 29 October they provided a bomber escort on a raid on Ramsgate. Following the end of the battle, the Italian force continued to carry out limited raids on England, and on 11 November 1940, four CR.42s acting as escorts were destroyed by RAF Hurricanes with no loss to the RAF. German ''Luftwaffe'' aircraft had difficulty flying in formation with the biplanes, which also proved to be poor match for the more modern British fighters, and the CR.42s were transferred back to the Mediterranean theatre. The Italians also fielded a small number of Fiat G.50 Freccia monoplane fighters. Similar to the Luftwaffe's Bf 109E, this fighter was restricted by its short range of barely , likely due to limited internal fuel, but unlike the German mainstay fighter, the lack of a radio unit in most participating aircraft also challenged its usability.

Gradually, with the introduction of the Bristol Beaufighter in 1940–41, its role was supplanted by its faster, better armed progeny. The first Beaufighters entered service in early September 1940, at first delivered in standard day fighter camouflage schemes although the type was intended for a night fighting role.

for which the Junkers Ju 87 ''Stuka'' was specifically designed. The Junkers Ju 88 was fitted with external dive brakes and a control system, similar to those of the Ju 87 and could carry out a dive bombing role, although it was primarily used as a level bomber. The light bomb loads carried by the Ju 87 had been used to great effect during the Battle of France. However, the Ju 87 was slow and possessed an inadequate degree of defensive weaponry, with only a single, 7.92mm calibre

at the rear of the cockpit for rearward defense. Furthermore, it could not be effectively protected by fighters, because of its low speed and the very low altitudes at which it ended its dive bomb attacks. The ''Stuka'' depended on air superiority, the very thing being contested over Britain. It was therefore withdrawn from attacks on Britain in August after prohibitive losses, leaving the ''Luftwaffe'' short of precision ground-attack aircraft. Another constraint was imposed by the light armament carried by the ''Luftwaffe'' bombers. At the start of the battle they were still armed with an average of three hand held MG 15 light machine guns, which were supplied by 75 round "saddle drum" magazines. When faced with concentrated attacks by modern fighters such as the Hurricane and Spitfire this proved totally inadequate. Although many of the ''Luftwaffe'' gunners were well trained and capable of hitting a fast moving fighter the damage done was seldom enough to stop the attack in time to prevent heavy damage being done to the bomber. The high rate of fire of the MG 15 meant that the small magazines emptied quickly; the time taken to reload often gave a fighter the time it needed to make a successful attack. Efforts had been made to increase the number of defensive weapons, but this also meant that because the weapons were hand-held either more crew members were needed in each aircraft, or the existing crew members could be overworked. It was a problem which was never to be fully resolved and the ''Luftwaffe'' bombers had to rely on the ability of their fighters to protect their formations. The bombers did enjoy some advantages. As more armour plate was added in vital areas, crew members became less vulnerable. Their fuel tanks were also well protected by layers of self-sealing rubber, although the incendiary and tracer ammunition which was carried by RAF fighters could sometimes ignite fuel vapour in empty tanks. The He 111 was nearly 100 mph slower than the Spitfire and didn't present much of a challenge to catch, although the heavy armour for the crew stations, self-sealing fuel tanks and progressively uprated defensive armament meant that it was still a challenge to shoot down. It was the most numerous German bomber type during the Battle, and was capable of delivering 2000 kg of bombs to the target, carried in an internal bomb bay – usually eight 250 kg bombs, stored vertically. Subsequent variants allowed further increase in the bomb load and the maximum size of bombs carried, with external bomb racks. The state-of-the art ''

began to take part in the Blitz of the winter of 1940–1941. The Do 17Z was an older type of German bomber that was no longer in production by the start of the Battle. Still, many ''Kampfgeschwadern'' still operated the Dornier, known as "the flying pencil" due to its sleek fuselage. Its air-cooled radial BMW engines meant that many of these aircraft were able to survive fighter attack because there was no vulnerable cooling system to disable. The Dornier was also manoeuvrable, and as a result was popular in the ''Luftwaffe''. The main problem with the Dornier was its limited 200 mile combat range, when fully loaded with bombs. Its bomb carrying capacity was also limited to 2,205 lbs. Older versions of the Do 17, mainly the E-1, were still used for weather reconnaissance duties. Of the four types of bomber used by the ''Luftwaffe'' the Ju 88 (the original ''Schnellbomber'') was considered to be the most difficult to shoot down. As a bomber it was relatively manoeuvrable and, especially at low altitudes with no bomb load, it was fast enough to ensure that a Spitfire engaged in a tail-chase would be hard pressed to catch up. It could carry up to 3,000 kg of bombs. However, only small sized 50 and 70 kg bombs, up to a total weight of 1,400 kg, could be carried internally, while larger bombs had to be carried on external racks, causing considerable drag. The Ju 88 was also extremely versatile, being fitted with both the

gyroscopic bomb sight and Stuvi dive sight as well as retractable dive brakes. The front MG 15 machine gun could be locked with an ingenious retracting clamp just forward of the windscreen to lock it for forwards firing, and could be used for strafing runs. Thus the Ju 88, dubbed as the "Big Stuka", was equally at home when it came to level or dive bombing or low-level attacks. The versions of the Ju 88 used during the battle were the small-wingtipped A-1 and the A-5; the latter incorporated several improvements, including the A-4's increased 20.08 meter wingspan and uprated armament. The Ju 88 C-1 heavy fighter version, with a sheet metal nose replacing the bombers' "beetle's-eye" faceted glazing, was also used in small numbers. In reality, the Ju 88, although operating in smaller numbers than the Do 17 and He 111, suffered the highest losses of the three German bomber types. Losses of Do 17 and He 111s amounted to 132 and 252 machines destroyed respectively, while 313 Ju 88s were lost. I./KG 40 was equipped with a small number of the four-engined

(CAI) was an expeditionary force of the ''Regia Aeronautica'' that participated in the very late stages of the Battle of Britain. The bomber element consisted of some 70 Fiat BR.20 twin engined bombers of ''13° Stormo'' and ''43° Stormo''. based in Belgium. The Italian BR.20 was a bomber capable of carrying 1600 kg (3,528 lb) of bombs. Supporting aircraft included five CANT Z.1007 used for reconnaissance duties and several Caproni Ca.133 transports. The Italian bomber force flew limited operations, undertaken towards the end of the battle. The CAI's bombers flew about 102 sorties, only one of which attained any notable success— severe damage being caused to a canning factory in Lowestoft by a raid on 29 November 1940, which killed three people.

and two becoming lost on their return. On 11 November a formation of 10 BR.20s escorted by Fiat CR.42 biplane fighters on a daylight raid on Harwich, was intercepted by RAF Hurricanes. Three bombers were downed and three CR.42s destroyed with four damaged, with no loss to the Hurricanes.Green and Swanborough 1982, p. 308. In early January 1941 all of the bombers were redeployed.
