Werner Mölders (18 March 1913 – 22 November 1941) was a World War II German Luftwaffe pilot, wing commander, and the leading German fighter ace in the Spanish Civil War. He became the first pilot in aviation history to shoot down 100 enemy aircraft and was highly decorated for his achievements. Mölders developed fighter tactics that led to the finger-four formation. He died in a plane crash as a passenger.

Mölders joined the Luftwaffe, the air force of Nazi Germany, in 1934. In 1938 he volunteered for service in Germany's Condor Legion, then supporting General Francisco Franco's Nationalist side in the Spanish Civil War, and shot down 14 aircraft. Following the start of World War II in 1939, he took part in the "Phoney War" of 1939–1940, the Battle of France of May to June 1940, and the Battle of Britain (July 1940 onwards). With his tally standing at 68 victories, Mölders and his unit, Jagdgeschwader 51 (JG 51), transferred to the Eastern Front in June 1941 for the opening of Operation Barbarossa, achieving 101 victories by mid-July 1941.

Prevented from flying further combat missions for propaganda reasons, at the age of 28 Mölders was appointed Inspector of Fighters. While inspecting the Luftwaffe units in the Crimea he received orders to return to Berlin to attend the state funeral of Ernst Udet, a Luftwaffe general and World War I flying ace. The aircraft in which Mölders was traveling as a passenger to Berlin experienced an engine failure and attempted an emergency landing. It crashed at Breslau, killing Mölders and two others.

The Luftwaffe and the West German Bundeswehr both honoured Mölders by naming two fighter wings, a destroyer and a barracks after him. In 1998 the German Parliament decided that members of the Condor Legion such as Mölders should "no longer be honoured". In 2005 the German Ministry of Defence decided to remove the name "Mölders" from the fighter wing still bearing his name.

Education and early career Mölders was born on 18 March 1913 in Gelsenkirchen, the son of teacher (Oberlehrer) Victor Mölders and his wife Annemarie Mölders, née Riedel. He was the third of four children, with an older sister, Annemarie, an older brother, Hans, and a younger brother, Victor. After his father, a Reserve Leutnant in the King's 145th Infantry Regiment, was killed in action on 2 March 1915 in the Argonne Forest in France, his mother moved the family into her parents' house in Brandenburg an der Havel.

In Brandenburg, Mölders found a benefactor in Father Erich Klawitter, who instilled firm religious beliefs in him. From 1919 to 1931, Mölders attended, first, the elementary school and then from 1922 the Saldria-Realgymnasium, a secondary school that enjoyed a supraregional reputation. In school he discovered his love for water sports, especially rowing. He joined two rowing clubs, first the Saldria-Brandenburg and later the Brandenburger Ruderclub, and enjoyed success at rowing-regattas. From 1 October 1925, he was also a member of the Bund Neudeutschland in der katholischen Jugendbewegung, a Catholic youth organisation. Mölders graduated from school in early 1931 with the Abitur (diploma) and expressed a desire to become an officer in the armed forces.

Mölders joined the Preußisches Infanterieregiment Nr. 2, an infantry regiment under the command of Oberst Siegfried Haenicke and subordinated to the 1st Division of the Reichswehr in Allenstein, East Prussia on 1 April 1931, serving as an officer cadet in the infantry. He attained the rank of Fahnenjunker-Gefreiter on 1 October 1931, rising to Fahnenjunker-Unteroffizier on 1 April 1932. After completing his basic military training in October 1932, he transferred to the Military School Dresden. On 1 June 1933, he successfully completed his training in Dresden and was promoted to ensign. He again was transferred, this time to the 1st Prussian Pioneer Battalion (Infantry Regiment 2) at the Pioneer School in Munich. During his training years, Mölders made his first attempt to fulfil his dream of flying and volunteered for pilot training, but was declared unfit for flying. He tried again and was given conditional permission (bedingt tauglich—with constraints) to begin flight training.

After his promotion to Oberfähnrich on 1 February 1934, Mölders began his pilot training at the Deutsche Verkehrsfliegerschule (German transport flying school) in Cottbus, lasting from 6 February 1934 to 31 December 1934. On 1 March 1934, he was promoted to Leutnant and assigned to the recently established Luftwaffe. In the early stages of his pilot training, he suffered continually from nausea and vomiting, but he eventually overcame these problems and finished the course at the top of his class. The next phase of his military pilot's training was from 1 January 1935 to 30 June 1935 at the combat flying school in Tutow and the Jagdfliegerschule (fighter pilot school) at Schleißheim near Munich. He received the newly created Pilot's Badge of the Luftwaffe on 21 May 1935.

On 1 July 1935, Leutnant Mölders was posted to Fliegergruppe Schwerin (I./JG 162 "Immelmann"). On 7 March 1936, during the remilitarisation of the Rhineland, Mölders and his squadron (Staffel) were moved to Düsseldorf. During this period, Mölders met Luise Baldauf, whom he was to marry a few years later, shortly before his death. On 20 April 1936, Adolf Hitler's birthday, numerous promotions were handed out, and Mölders advanced to Oberleutnant, effective as of 1 April 1936. At the same time, he became leader of the fighter training squadron of the 2nd Group of Jagdgeschwader 134 "Horst Wessel". This group was under the command of Major Theo Osterkamp, who became another of Mölders' early mentors. Mölders was appointed squadron leader (Staffelkapitän) of the 1st squadron of Jagdgeschwader 334 on 15 March 1937 and served as an instructor in Wiesbaden.

Condor Legion In 1936, the Germans sent a Luftwaffe force, the Condor Legion, to assist the Nationalists in the Spanish Civil War. Mölders volunteered for service, and arrived by sea in Cádiz on 14 April 1938. He was assigned to the 3. Staffel (3rd squadron) of Jagdgruppe 88 (J/88) commanded by Oberleutnant Adolf Galland. The unit, stationed at the Valencia–Ebro front, was equipped with the Heinkel He 51, but later switched to the Messerschmitt Bf 109.The Condor Legion used the Bf 109B through D variants during the conflict. This provided valuable combat experience for both the Luftwaffe and Messerschmitt leading up to the start of World War II. The He 51s were turned over to the 4th squadron, commanded by Hauptmann Eberhard d'Elsa, and continued in service until the end of the Spanish Civil War. Mölders assumed command of the squadron on 24 May 1938, when Galland returned to Germany. He claimed his first aerial victory, shooting down a Polikarpov I-15 "Chato" ("Curtiss" to the Germans) near Algar, on 15 July 1938. Over the remaining months of the year, Mölders became the leading ace of the Condor Legion, claiming 15 aircraft in Spain: two I-15 "Curtiss", 12 I-16 "Rata" and one Tupolev SB (one "Rata" claimed on 23 September 1938 was not confirmed).

In recognition of his exceptional performance as a commander and fighter pilot, Mölders was promoted to Hauptmann (Captain) on 18 October 1938, effective as of 1 October 1938. He claimed his 14th and final confirmed aerial victory of the conflict by downing a Polikarpov I-16 "Rata" near Mola on 3 November 1938. On 5 December, he passed on command of 3. Staffel to Hubertus von Bonin and flew from La Cenia back to Germany on a Junkers Ju 52. From 6 December 1938 until March 1939, Mölders was a member of the 1st group of Jagdgeschwader 133 (JG 133) and held a staff position with the Inspector of Fighters at the Ministry of Aviation in Berlin. His task was to devise new fighter pilot tactics. In March 1939 he was given command as Staffelkapitän of 1./JG 133, taking over command from Oberleutnant Hubertus von Bonin. JG 133 was later renamed Jagdgeschwader 53 Pik As (Ace of Spades).For an explanation of Luftwaffe unit designations see Organisation of the Luftwaffe during World War II.

For his achievements in Spain, Mölders was honoured with the Spanish Medalla de la Campaña and Medalla Militar on 4 May 1939 and the German Spanish Cross in Gold with Swords and Diamonds () on 6 June 1939. The Condor Legion officially returned to Germany on 6 June 1939 and troops marched through Berlin to the Lustgarten, where the fallen were honoured. A formal state banquet for the most highly decorated soldiers was held in the marble gallery of the Reich Chancellery. Mölders was seated at table 1, with General der Flieger Hugo Sperrle, General Antonio Aranda, General Gonzalo Queipo de Llano, Oberst Walter Warlimont, Oberstleutnant Hans von Donat, Leutnant Reinhard Seiler and Oberfeldwebel Ignaz Prestele.

Tactical innovations With other airmen in Spain, Mölders developed the formation known as the "finger-four". This improved the all-round field of vision and combat flexibility of a flight (Schwarm), enhanced mutual protection, and encouraged pilot initiative. In the "finger-four", the aircraft assumed positions corresponding to the fingertips of an outstretched hand. The fighters flew in two elements (Rotten) of two aircraft each; two Rotten (four aircraft) made up a Schwarm (swarm).

Mölders is often credited with inventing the cross-over turn. An early version of the manoeuvre, as used by a "Vic" of five aircraft (a tight formation forming the letter "V"), appeared in the Royal Air Force (RAF) Training Manual of 1922, and the manoeuvre may even date back to 1918. However, it had fallen into disuse due to the difficulty of performing it in a multi-aircraft formation with the contemporary spacing of less than between aircraft. The wide lateral separation of introduced by J 88 both necessitated such a turning manoeuvre, to enable a Schwarm to turn as a unit, and minimised the risk of midair collisions previously associated with it.

World War II

Phoney War and the Battle of France At the outbreak of World War II on 1 September 1939, Mölders' Staffel was stationed in the west protecting Germany's border in the Mosel–Saar–Pfalz region. On 8 September 1939, Mölders' fighter suffered an engine failure; he crash-landed, flipping the aircraft over and injuring his back. The injury kept him out of combat for several days. He returned to flying on 19 September. The following day, between Contz and Sierck, at the apex of the Dreiländereck, over the three borders area, he shot down his first aircraft of the war, a Curtiss P-36 (according to other historians, it was one of a trio of French Hawk H-75As), of Groupe de Chasse II/5 (Sgt Queginer bailed out). Thanks to that victory, he earned the Iron Cross 2nd Class (). He recalled his first victory:

On 26 September 1939, JG 53 was ordered to form its III. Gruppe. Mölders relinquished command of 1./JG 53 to Oberleutnant Hans-Karl Mayer and organised the formation of III./JG 53 at Wiesbaden-Erbenheim Airfield; within two weeks, Gruppenkommandeur Mölders reported that the Gruppe was conditionally operational with 40 pilots and 48 aircraft.

On 22 December, Mölders, leading four Bf 109s from III./JG 53, engaged three Hawker Hurricanes over the Saar River, between Metz and Thionville, that were trying to intercept an unidentified aircraft. Mölders and Hans von Hahn shot down two Hurricanes flown by Sergeants R. M. Perry and J. Winn, becoming the first German fighter pilots to shoot down a Hawker Hurricane. Mölders shot down another Hurricane on 2 April, when he forced Flight Lieutenant C. D. "Pussy" Palmer of No. 1 Squadron RAF, to bail out, and on 20 April, he destroyed a French Curtiss P-36 Hawk (H-75A) east of Saarbrücken.
