On 25 August 1936,
Oberleutnant Eberhardt Kraft and
Oberleutnant Hannes Trautloft each claimed a
Republican Bréguet 19 light bomber, one of which was the unit's first claim in Spain. Meantime aid from the Soviet Union arrived for the Republican forces. The supplied Soviet fighters (
Polikarpov I-15 and
I-16) easily outperformed the
Heinkel He 51s, and in late 1936, three
Messerschmitt Bf 109 prototypes were sent to J/88, and soon followed by the first 15 of the latest Bf 109As. A
He 112 V6 prototype was also sent. Armed with a single 20 mm cannon firing through the airscrew hub, the
Kanonenvogel (cannon bird) was to be evaluated as a ground attack aircraft and assigned to
Jagdgruppe 88 at
Almorox in March. Over the next few months the He 112 V6 was flown by several pilots, but on 19 July 1937, with
Unteroffizier Max Schulze flying, the engine seized during landing, and the He 112 V6 broke its back and was written off. ,
Jagdgruppe 88, Legion Condor The first unit to fly the Bf 109 was
2. Staffel, commanded by
Oberleutnant Günther Lützow. The unit initially suffered several landing accidents, until the pilots became familiar with taking off and landing on the narrow‑track undercarriage. The first major action of 2.J/88 with the Bf 109, took place during the
Battle of Brunete in July 1937. Based near
Ávila, its main mission was to escort the
Junkers Ju 52 bombers. The Bf 109s, utilising superior tactics developed by
Leutnant Werner Mölders, turned air superiority in favour of the Condor Legion. The Bf 109s drew first blood on 8 July 1937 when
Leutnant Rolf Pingel and Uzz. Guido Höness claimed two
Tupolev SB‑2 bombers. Air combats fought on 12 July resulted in two
Aero A.101s claimed by Höness, an SB‑2 to Pingel, and three I‑16s by Pingel, Fw. Peter Boddem and Fw. Adolf Buhl. Höness became the first Bf 109 loss, probably shot down and killed by a Republican I-16 flown by American
Frank Tinker. The Condor Legion lost eight aircraft, but J/88 fighters claimed 18 victories. On 24 July Republican forces launched their final major offensive, the
Battle of the Ebro. Reconnaissance aircraft of the Condor Legion noticed the troop build-up, and while the Republic forced gained ground, they failed to take Gandesa, due to intensive ( over 400) sorties by 70 Legion aircraft. The rest of the battle saw a series of air strikes, followed by a Nationalist counter-offensive. During the 113-day battle, only 10 aircraft were lost and 14 damaged; the Legion claimed 100 Republican aircraft destroyed, a third of those lost. Only 5 aircrew had been killed, and 6 captured. Some 19 Bf 109C-1s, with a fuel‑injected Jumo 210G engine and four 7.92 mm machine guns, arrived in Spain in the spring 1938, followed by nine Bf 109Ds in August. In February 1939 the latest Bf 109E‑1 model was sent to
Jagdgruppe 88, with
2. Staffel converting from early Bf 109 in late February 1939, just prior to the end of the War. The unit then took part in operations against the remnants of the Republican Air Force through early 1939, with considerable success. The men of J/88 returned to Germany in May 1939. 365 aircraft were claimed destroyed by
Jagdgruppe 88, and 26 pilots claimed 5 kills or more.
