Jagdgeschwader 4

II./JG 4 Sturmgruppe was formed on 12 July 1944 at Salzwedel from I./Zerstörergeschwader 1 (ZG 1) and from elements of Major Hans-Günter von Kornatzki's Sturmstaffel 1. The gruppe was equipped with the modified and heavily armoured FW 190A-8/R2. While the heavily armoured fighters proved effective against the heavy bombers of the USAAF, they proved vulnerable to the numerous escort fighters and hence suffered heavy losses. III./JG 4 was also formed in July 1944 from III./ZG 1 in Rotenburg.

In common with other fighter units engaged in

On 11 September 1944 II.(Sturm)/JG 4 escorted by III. Gruppe intercepted a USAAF bombing raid near Chemnitz. Attacking the 100th and 95th Bomb Groups the Geschwader claimed some 13 destroyed bombers. Intercepted by the 339th and 55th Fighter Groups JG 4 was severely mauled, and lost 21 pilots killed and 9 more were seriously injured during the mission.

In October 1944 IV./JG 4 was formed from elements of II./

On 2 November the Sturmgruppe, in conjunction with IV./JG 3, intercepted American bomber formations in the Leipzig area. II./JG 4 attacked the 457th Bombardment Group and destroyed nine B-17s, although the Gruppe lost 16 Fw 190s out of 22 committed to the massed US fighter escorts.

From November 1944 onwards the Geschwader, operating from

During

On 21 January 1945 the four Gruppen of JG 4 were switched to Luftlotte 6 on the Eastern Front and pitchforked wholesale into ground-attack missions, for which the unit was ill-equipped and pilots untrained. By early February 1945 II.(Sturm)/JG 4 were located at Neuhausen under Major Gerhard Schroeder in defence of Cottbus.

Although nearly 400 vehicles were claimed destroyed, losses during the month inevitably emasculated the unit, with some 57 aircraft lost, with 26 pilots killed or missing and 14 wounded.^[4]

I./JG 4 was dissolved during March 1945 and the remustering of the unit personnel as infantry followed. Elements of JG 4 flew their last sorties against the Soviet armies and air forces around Berlin and in late April 1945 the unit withdrew to the Schleswig-Holstein area and disbanded on 8 May 1945.

Insignia

Some JG 4 aircraft displayed on the engine cowling the Geschwaderzeichen, a blue escutcheon with a grey or silver knight’s helmet with a red (red-white) plume.

This insignia was first used by II. Gruppe, but later also appeared on other JG 4 Gruppen aircraft.
