Keller". Excellent. The V-1 flying bomb (German: Vergeltungswaffe 1 "Vengeance Weapon 1") was an early cruise missile. Its official Reich Aviation Ministry (RLM) designation was Fieseler Fi 103 and its suggestive name was Höllenhund (hellhound). It was also known to the Allies as the buzz bomb or doodlebug and in Germany as Kirschkern (cherry stone) or Maikäfer (maybug). The V-1 was the first of the Vergeltungswaffen (V-weapons) deployed for the terror bombing of London. It was developed at Peenemünde Army Research Center in 1939 by the Luftwaffe at the beginning of the Second World War, and during initial development was known by the codename "Cherry Stone". Due to its limited range, the thousands of V-1 missiles launched into England were fired from launch facilities along the French (Pas-de-Calais) and Dutch coasts or by modified He 111 aircraft. The Wehrmacht first launched the V-1s against London on 13 June 1944, one week after (and prompted by) the successful Allied landings in France. At peak, more than one hundred V-1s a day were fired at southeast England, 9,521 in total, decreasing in number as sites were overrun until October 1944, when the last V-1 site in range of Britain was overrun by Allied forces. After this, the Germans directed V-1s at the port of Antwerp and at other targets in Belgium, launching a further 2,448 V-1s. The attacks stopped only a month before the war in Europe ended, when the last launch site in the Low Countries was overrun on 29 March 1945. As part of operations against the V-1, the British operated an arrangement of air defences, including anti-aircraft guns, barrage balloons, and fighter aircraft, to intercept the bombs before they reached their targets, while the launch sites and underground storage depots became targets for Allied attacks including strategic bombing. In 1944 a number of tests of this weapon were apparently conducted in Tornio, Finland. On one occasion, several Finnish soldiers saw a German plane launch what they described as a bomb shaped like a small, winged aircraft. The flight and impact of another prototype was seen by Finnish frontline soldiers; they noted that its engine stopped suddenly, causing the V-1 to descend sharply, and explode on impact, leaving a crater 20–30 metres (66–98 ft) wide. These V-1s became known to Finnish soldiers as "flying torpedoes". Design and development: In 1935 Paul Schmidt and Professor Georg Hans Madelung submitted a design to the Luftwaffe for a flying bomb. It was an innovative design that used a pulse-jet engine, while previous work dating back to 1915 by Sperry Gyroscope relied on propellers. While employed by the Argus Motoren company, Fritz Gosslau developed a remote-controlled target drone, the FZG 43 (Flakzielgerät-43). In October 1939 Argus proposed Fernfeuer, a remote-controlled aircraft carrying a payload of one ton, that could return to base after releasing its bomb. Argus worked in co-operation with C. Lorenz AG and Arado Flugzeugwerke to develop the project. However, the Luftwaffe declined to award them a development contract. In 1940, Schmidt and Argus began cooperating, integrating Schmidt's shutter system with Argus' atomized fuel injection. Tests began in January 1941, and the first flight made on 30 April 1941 with a Gotha Go 145. On 27 February 1942 Gosslau and Robert Lusser sketched out the design of an aircraft with the pulse-jet above the tail, the basis for the future V-1. Lusser produced a preliminary design in April 1942, P35 Erfurt, which used gyroscopes. When submitted to the Luftwaffe on 5 June 1942, the specifications included a range of 300 km (186 miles), a speed of 700 km/h (435 mph), and capable of delivering a 500-kilogram (1/2-long-ton) warhead. Project Fieseler Fi 103 was approved on 19 June, and assigned code name Kirschkern and cover name Flakzielgerät 76 (FZG-76). Flight tests were conducted at the Luftwaffe's Erprobungsstelle coastal test centre at Karlshagen, Peenemünde-West.  Erhard Milch, State Secretary in the Reich Ministry of Aviation and Inspector General of the Air force, awarded Argus the contract for the engine, Fieseler the airframe, and Askania the guidance system. By 30 August Fieseler had completed the first fuselage, and the first flight of the Fi 103 V7 took place on 10 December 1942, when it was airdropped by a Fw 200. Then on Christmas Eve, the V-1 flew 900 m (1,000 yd), for about a minute, after a ground launch. On 26 May 1943 Germany decided to put both the V-1 and the V-2 into production. In July 1943 the V-1 flew 245 kilometres (152 mi) and impacted within a kilometre (1,100 yards) of its target. The V-1 was named by Das Reich journalist Hans Schwarz Van Berkl in June 1944 with Hitler's approval. Description: The V-1 was designed under the codename Kirschkern (cherry stone) by Lusser and Gosslau, with a fuselage constructed mainly of welded sheet steel and wings built of plywood. The simple, Argus-built pulsejet engine pulsed 50 times per second, and the characteristic buzzing sound gave rise to the colloquial names "buzz bomb" or "doodlebug" (a common name for a wide variety of flying insects). It was known briefly in Germany (on Hitler's orders) as Maikäfer (May bug literally "May" + "chafer") and Krähe (crow). Power plant: The Argus pulsejet's major components included the nacelle, fuel jets, flap valve grid, mixing chamber venturi, tail pipe, and spark plug. Compressed air rather than a fuel pump forced gasoline from the 640 L (140 imp gal; 170 US gal) fuel tank through the fuel jets which consisted of three banks of three atomizers. These nine atomizing nozzles were in front of the air inlet valve system where it mixed with air before entering the chamber. A throttle valve, connected to altitude and ram pressure instruments, controlled fuel flow. Schmidt's spring-controlled flap valve system provided an efficient straight path for incoming air. The flaps momentarily closed after each explosion, the resultant gas compressed in the venturi chamber, and its tapered portion accelerated the exhaust gases creating thrust. The operation proceeded at a rate of 42 cycles per second. Beginning in January 1941, the V-1's pulsejet engine was also tested on a variety of craft, including automobiles and an experimental attack boat known as the Tornado, in which a boat loaded with a 700 kg (1,543 lb) warhead was steered towards a target ship either by remote control or by a pilot who would leap out of the back at the last moment. The Tornado was assembled from surplus seaplane hulls connected in catamaran fashion. Ultimately insufficient Argus 014 pulse-jets were available as all production was allocated to the V-1 missile program. The engine made its first flight aboard a Gotha Go 145 on 30 April 1941. Guidance system: The V-1 guidance system used a simple autopilot developed by Askania in Berlin to regulate altitude and airspeed. A pair of gyroscopes controlled yaw and pitch, while azimuth was maintained by a magnetic compass. Altitude was maintained by a barometric device. Two spherical tanks contained compressed air at 6.2 megapascals (900 psi), that drove the gyros, operated the pneumatic servomotors controlling the rudder and elevator, and pressurized the fuel system. The magnetic compass was located near the front of the V-1, within a wooden sphere. Shortly before launch, the V-1 was suspended inside the Compass Swinging Building (Richthaus). There the compass was corrected for magnetic variance and magnetic deviation. The RLM at first planned to use a radio control system with the V-1 for precision attacks, but the government decided instead to use the missile against London. Some flying bombs were equipped with a basic radio transmitter operating in the range of 340–450 kHz. Once over the channel, the radio would be switched on by the vane counter, and a 120-metre (400 ft) aerial deployed. A coded Morse signal, unique to each V-1 site, transmitted the route, and impact zone calculated once the radio stopped transmitting. An odometer driven by a vane anemometer on the nose determined when the target area had been reached, accurate enough for area bombing. Before launch, it was set to count backwards from a value that would reach zero upon arrival at the target in the prevailing wind conditions. As the missile flew, the airflow turned the propeller, and every 30 rotations of the propeller counted down one number on the odometer. This odometer triggered the arming of the warhead after about 60 km (37 mi). When the count reached zero, two detonating bolts were fired. Two spoilers on the elevator were released, the linkage between the elevator and servo was jammed, and a guillotine device cut off the control hoses to the rudder servo, setting the rudder in neutral. These actions put the V-1 into a steep dive. While this was originally intended to be a power dive, in practice the dive caused the fuel flow to cease, which stopped the engine. The sudden silence after the buzzing alerted people under the flight path to the impending impact. Initially, V-1s landed within a circle 31 km (19 mi) in diameter, but by the end of the war, accuracy had been improved to about 11 km (7 mi), which was comparable to the V-2 rocket. Warhead: The warhead consisted of 850 kg (1,870 lb) of Amatol, 52A+ high-grade, blast-effective explosive with three fuses. An electrical fuse could be triggered by nose or belly impact. Another fuse was a slow-acting mechanical fuse allowing deeper penetration into the ground, regardless of the altitude. The third fuse was a delayed action fuse, set to go off two hours after launch. The purpose of the third fuse was to avoid the risk of this secret weapon being examined by the British. It's time delay was too short to be a useful booby trap but was instead meant to destroy the weapon if a soft landing had not triggered the impact fuses. These fusing systems were very reliable, and almost no dud V-1s were recovered. Walter catapult: Ground-launched V-1s were propelled up an inclined launch ramp by an apparatus known as a Dampferzeuger ("steam generator"), in which steam was generated when hydrogen peroxide (T-Stoff) was mixed with sodium permanganate (Z-Stoff). Designed by Hellmuth Walter Kommanditgesellschaft, the WR 2.3 Schlitzrohrschleuder consisted of a small gas generator trailer, where the T-Stoff and Z-Stoff combined, generating high-pressure steam that was fed into a tube within the launch rail box. A piston in the tube, connected underneath the missile, was propelled forward by the steam. It is a common misconception that the steam launch was to allow the engine to start running but the real reason was that the Argus had insufficient power to propel the V1 to a speed above its extremely high stall speed. The launch rail was 49 m (160 ft) long, consisting of eight modular sections, each 6 m (20 ft) long, and a muzzle brake. Production of the Walter catapult began in January 1944. The Walter catapult accelerated the V-1 to a launch speed of 320 km/h (200 mph), well above the needed minimum operational speed of 240 km/h (150 mph). The V-1 made British landfall at 550 km/h (340 mph), but accelerated to 640 km/h (400 mph) by the time it reached London, as its 570 L (150 US gal) of fuel burned off. On 18 June 1943 Hermann Göring decided on launching the V-1, using the Walter catapult, in both large launch bunkers, called Wasserwerk, and lighter installations, called the Stellungsystem. The Wasserwerk bunker measured 215 m (705 ft) long, 36 m (118 ft) wide, and 10 m (33 ft) high. Four were initially to be built: Wasserwerk Desvres, Wasserwerk St. Pol, Wasserwerk Valognes, and Wasserwerk Cherbourg. Stellungsystem-I was to be operated by Flak Regiment 155(W), with 4 launch battalions, each having 4 launchers, and located in the Pas-de-Calais region. Stellungsystem-II, with 32 sites, was to act as a reserve unit. Stellungsystem-I and II had nine batteries manned by February 1944. Stellungsystem-III, operated by FR 255(W), was to be organized in the spring of 1944, and located between Rouen and Caen. The Stellungsystem locations included distinctive catapult walls pointed towards London, several J-shaped stowage buildings referred to as "ski" buildings as on aerial reconnaissance photographs the buildings looked like a ski on its side, and a compass correction building which was constructed without ferrous metal. In the spring of 1944, Oberst Schmalschläger had developed a more simplified launching site, called Einsatz Stellungen. Less conspicuous, 80 launch sites and 16 support sites were located from Calais to Normandy. Each site took only two weeks to construct, using 40 men, and the Walter catapult only took 7–8 days to erect, when the time was ready to make it operational. Once near the launch ramp, the wing spar and wings were attached and the missile was slid off the loading trolley, Zubringerwagen, onto the launch ramp. The ramp catapult was powered by the Dampferzeuger trolley. The pulse-jet engine was started by the Anlassgerät, which provided compressed air for the engine intake, and electrical connection to the engine spark plug, and autopilot. The Bosch spark plug was only needed to start the engine, while residual flame ignited further mixtures of gasoline and air, and the engine would be at full power after 7 seconds. The catapult would then accelerate the bomb above its stall speed of 320 km/h (200 mph), ensuring sufficient ram air. Operation Eisbär: Mass production of the FZG-76 did not start until the spring of 1944, and FR 155(W) was not equipped until late May 1944. Operation Eisbär, the missile attacks on London, commenced on 12 June. However, the four launch battalions could only operate from the Pas-de-Calais area, amounting to only 72 launchers. They had been supplied with missiles, Walter catapults, fuel, and other associated equipment since D-Day. None of the nine missiles launched on the 12th reached England, while only four did so on the 13th. The next attempt to start the attack occurred on the night of 15/16 June, when 144 missiles reached England, of which 73 struck London, while 53 struck Portsmouth and Southampton. Damage was widespread and Eisenhower ordered attacks on the V-1 sites as a priority. Operation Cobra forced a retreat from the French launch sites in August, with the last battalion leaving on 29 August. Operation Donnerschlag began from Germany on 21 October 1944. Operation and effectiveness: On 13 June 1944, the first V-1 struck London next to the railway bridge on Grove Road, Mile End, which now carries this English Heritage blue plaque. Eight civilians were killed in the blast. The first complete V-1 airframe was delivered on 30 August 1942,  and after the first complete As.109-014 was delivered in September, the first glide test flight was on 28 October 1942 at Peenemünde, from under a Focke-Wulf Fw 200. The first powered trial was on 10 December, launched from beneath an He 111. The LXV Armeekorps z.b.V. ("65th Army Corps for special deployment) formed during the last days of November 1943 in France commanded by General der Artillerie z.V. Erich Heinemann was responsible for the operational use of V-1. The conventional launch sites could theoretically launch about 15 V-1s per day, but this rate was difficult to achieve on a consistent basis; the maximum rate achieved was 18. Overall, only about 25% of the V-1s hit their targets, the majority being lost because of a combination of defensive measures, mechanical unreliability or guidance errors. With the capture or destruction of the launch facilities used to attack England, the V-1s were employed in attacks against strategic points in Belgium, primarily the port of Antwerp. Launches against Britain were met by a variety of countermeasures, including barrage balloons and aircraft such as the Hawker Tempest and newly introduced jet Gloster Meteor. These measures were so successful that by August 1944 about 80% of V-1s were being destroyed The Meteors suffered from frequent cannon failures, and accounted for only 13 V-1s destroyed In all, about 1,000 V-1s were destroyed by aircraft. The intended operational altitude was originally set at 2,750 m (9,000 ft), but repeated failures of a barometric fuel-pressure regulator led to the operational height being halved in May 1944, bringing V-1s into range of the 40 mm Bofors light anti-aircraft guns commonly used by Allied AA units. The trial versions of the V-1 were air-launched. Most operational V-1s were launched from static sites on land, but from July 1944 to January 1945, the Luftwaffe launched approximately 1,176 from modified Heinkel He 111 H-22s of the Luftwaffe's Kampfgeschwader 3 (3rd Bomber Wing, the so-called "Blitz Wing") flying over the North Sea. Apart from the obvious motive of permitting the bombardment campaign to continue after static ground sites on the French coast were lost, air launching gave the Luftwaffe the opportunity to outflank the increasingly effective ground and air defences put up by the British against the missile. To minimise the associated risks (primarily radar detection), the aircrews developed a tactic called "lo-hi-lo": the He 111s would, upon leaving their airbases and crossing the coast, descend to an exceptionally low altitude. When the launch point was neared, the bombers would swiftly ascend, fire their V-1s, and then rapidly descend again to the previous "wave-top" level for the return flight. Research after the war estimated a 40% failure rate of air-launched V-1s, and the He 111s used in this role were vulnerable to night-fighter attack, as the launch lit up the area around the aircraft for several seconds. The combat potential of air-launched V-1s dwindled during 1944 at about the same rate as that of the ground-launched missiles, as the British gradually took the measure of the weapon and developed increasingly effective defence tactics.
