JG 302 made a known total of at least 348 air victory claims[1] The unit's primary mission, when formed in late 1943, was to intercept Royal Air Force (RAF) heavy bombers at night, flying modified single-engined day fighters.

Eventually JG 302 also engaged United States Army Air Forces (USAAF) bombers by day.

On 6/7 February 1944 the Soviet Long-Range Bomber Force (ADD) launched a series of large scale air raids against Helsinki.

Thus, early in 1944 elements of I./JG 302 were temporarily transferred North to Nachtjagd-Kommando Helsinki to assist in the city's defence.

On 12 February 1944, 12 Messerschmitt Bf 109G-6/R6 night-fighters of I. Gruppe arrived at Malmi airfield from Jüterbog in Germany.

However, he was wounded in the right arm during this combat and had to make an emergency landing with his Bf 109 G-6 near the Götzendorft airfield.

On 25 July 1944 420 B-17s and B-24s bombed the tank factories in Linz while other bombers hit the Villach marshalling yards.
