Hugo Dahmer (7 May 1918 – 1 August 2006) was a German Luftwaffe military aviator during World War II, a fighter ace credited with 45, potentially 57, enemy aircraft shot down in 307 combat missions.

In early 1941, he was transferred to I. Gruppe (1st group) of Jagdgeschwader 77 (JG 77—77th Fighter Wing) which was based in Norway.

In late 1942, Dahmer was transferred to Jagdgeschwader 2 "Richthofen" (JG 2—2nd Fighter Wing) which was fighting on the Western Front.

Following World War II, he served in the newly established West Germany's Air Force in the Bundeswehr.

On 16 August 1938, Dahmer crashed Messerschmitt Bf 109 D-1 (Werknummer 447—factory number), the aircraft assigned to the Gruppenkommandeur (group commander) Oberstleutnant Eduard Ritter von Schleich, on a maintenance flight near Düsseldorf.

[4] World War II in Europe began on Friday 1 September 1939 when German forces invaded Poland.

Since the Armée de l'air reported no losses in this area of operations, the opponents may have been Royal Air Force (RAF) Hawker Hurricane fighters from No.

[6] On 28 May during the Battle of Dunkirk, Dahmer claimed a Supermarine Spitfire fighter shot down over the Thames Estuary.

JG 26 flew three combat air patrols to the northern banks of the Thames Estuary.

[11] On 24 September, on a mission to London, Dahmer was credited with shooting down a Hurricane fighter near Southend.

This unit was based at Stavanger-Sola and was tasked with providing fighter escort for German shipping on the southern and western Norwegian coast.

Staffel was detached from the Gruppe and relocated to Kirkenes Airfield in preparation of Operation Barbarossa, the German invasion of the Soviet Union.

Petsamo (zur besonderen Verwendung—for special deployment) and headed by Major Hennig Strümpell.

[21] On 30 July, Dahmer was presented the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes), the first pilot to receive this distinction on the Eismeerfront (Ice Sea Front)—the area of operations nearest the Arctic Ocean.

[22][Note 2] On 12 October, Dahmer led a formation which intercepted a flight of Tupolev SB-2 bombers from 137 BAP (Bombardirovochnyy Aviatsionyy Polk—bomber aviation regiment) over Lake Tolvand.

[24] In January 1942, Jagdgeschwader 5 (JG 5—5th Fighter Wing) was newly created and placed under the command of Oberst Carl-Alfred Schumacher.

Gruppe of JG 2 headed by Hauptmann Egon Mayer and was based at Vannes, France.

[27] On 23 January 1943, the United States Army Air Forces (USAAF) VIII Bomber Command attacked the U-boat base at Lorient.

Defending against this attack, Dahmer claimed his first aerial victory with JG 2 when he shot down a Boeing B-17 Flying Fortress heavy bomber.

[30] On 11 September, Dahmer was shot down in aerial combat with Spitfire and Republic P-47 Thunderbolt fighters.

Although he managed to bail out of his Focke-Wulf Fw 190 A-5 (Werknummer 1171) 5 kilometers (3.1 miles) north of Rouen, Dahmer was severely injured.

[33] Obermaier lists him with 45 aerial victories, plus further twelve unconfirmed claims, achieved in 307 combat missions.
