Heinkel He 162 Volksjäger

In January 1945, the Luftwaffe formed an Erprobungskommando 162 ("Test Unit 162") evaluation group to which the first 46 aircraft were delivered. The group was based at the Luftwaffe main test center, or Erprobungsstelle at Rechlin and it is frequently stated this unit was under the command of Heinz Bär. Bär, an experienced combat pilot credited with more than 200 kills, gained 16 of his victories with a Me 262 as commander of operational training unit III./Ergänzungs-Jagdgeschwader 2 (EJG 2). However, Bär's personal documents do not confirm his presence at Erprobungskommando 162 or if he ever flew He 162s.

February saw deliveries of the He 162 to its first operational unit, I./JG 1 (1st Group of Jagdgeschwader 1 Oesau — "1st Fighter Wing"), which had previously flown the Focke-Wulf Fw 190A. I./JG 1 was transferred to Parchim, which, at the time, was also a base for the Me 262-equipped Jagdgeschwader 7, some 80 km south-southwest of the Heinkel factory's coastal airfield at "Marienehe" (today known as Rostock-Schmarl, northwest of the Rostock city centre), where the pilots could pick up their new jets and start intensive training beginning in March 1945. This was all happening simultaneously with unrelenting Allied air attacks on the transportation network, aircraft production facilities and petroleum, oil, and lubrication (POL) product-making installations of the Third Reich — these had now begun to also target the Luftwaffe's jet and rocket fighter bases as well. On 7 April, the USAAF bombed the field at Parchim with 134 B-17 Flying Fortresses, inflicting serious losses and damage to the infrastructure. Two days later, I./JG 1 moved to an airfield at nearby Ludwigslust and, less than a week later, moved again to an airfield at Leck, near the Danish border. On 8 April, II./JG 1 moved to Heinkel's aforementioned Rostock northwestern coastal suburban factory airfield and started converting from Fw 190As to He 162s. III./JG 1 was also scheduled to convert to the He 162, but the Gruppe disbanded on 24 April and its personnel were used to fill in the vacancies in other units.

The He 162 first saw combat in mid-April 1945. On 19 April, Feldwebel Günther Kirchner shot down a Royal Air Force fighter, and although the victory was credited to a flak unit, the British pilot confirmed during interrogation that he had been downed by an He 162. The Heinkel and its pilot were lost as well, shot down by an RAF Hawker Tempest while on approach to land, a point at which Allied pilots targeted German jets. Though still in training, I./JG 1 had begun to score kills in mid-April, but had also lost 13 He 162s and 10 pilots. Ten of the aircraft were operational losses, caused by flameouts and sporadic structural failures. Only two of the 13 aircraft were actually shot down. The He 162's 30-minute fuel capacity also caused problems, as at least two of JG 1's pilots were killed attempting emergency deadstick landings after exhausting their fuel.

During its exceedingly brief operational service career, the 162's cartridge-type ejector seat was employed under combat conditions by JG1 pilots at least three times. The first recorded use was by Lt Rudolf Schmidt on April 20, with Fw Erwin Steeb ejecting from his 162 the following day. Finally, Hptm Paul-Heinrich Dahne attempted an ejection on April 24, but was killed when the aircraft's cockpit canopy failed to detach.

In the last days of April, as the Soviet troops approached, II./JG 1 evacuated from Marienehe and on 2 May joined the I./JG 1 at Leck. On 3 May, all of JG 1's surviving He 162s were restructured into two groups, I. Einsatz ("Combat") and II. Sammel ("Collection"). All JG 1's aircraft were grounded on 5 May, when General Admiral Hans-Georg von Friedeburg signed the surrender of all German armed forces in the Netherlands, Northwest Germany and Denmark. On 6 May, when the British reached their airfields, JG 1 turned their He 162s over to the Allies, and examples were shipped to the U.S., Britain, France, and the Soviet Union for further evaluation. Erprobungskommando 162 fighters, which had been passed on to JV 44, an elite jet unit under Adolf Galland a few weeks earlier, were all destroyed by their crews to keep them from falling into Allied hands. By the time of the German unconditional surrender on 8 May 1945, 120 He 162s had been delivered; a further 200 had been completed and were awaiting collection or flight-testing; and about 600 more were in various stages of production.

The difficulties experienced by the He 162 were caused mainly by its rush into production, not by any inherent design flaws. One experienced Luftwaffe pilot who flew it called it a "first-class combat aircraft." Eric "Winkle" Brown of the Fleet Air Arm, who flew a record 486 different types of aircraft, said the He 162 had "the lightest and most effective aerodynamically balanced controls" he had experienced. Brown had been warned to treat the rudder with suspicion due to a number of in-flight failures. This warning was passed on by Brown to RAF pilot Flt Lt R A Marks, but was apparently not heeded. On 9 November 1945, during a demonstration flight from RAE Farnborough, one of the fin and rudder assemblies broke off at the start of a low-level roll causing the aircraft to crash into Oudenarde Barracks, Aldershot, killing Marks and a soldier on the ground.
