NJG 11 was the Luftwaffe's only Nachtjagdgeschwader to exclusively fly single-engine, single-seat fighter aircraft in the Wilde Sau role.

Concentrating efforts over the Ruhr and Berlin, tactics were to create lighter conditions by setting up searchlight boxes, forming 'light horizons' to enable pilots to make visible contact with the enemy aircraft.

In December 1944 the piston-engined elements of NJG 11 gave up sustained anti-Mosquito operations and confined itself to illuminated target defence night fighting against the heavy bombers of the RAF.

10./NJG 11 under Hauptmann Kurt Welter, an experienced Wilde Sau ace, commenced operations using a handful of single-seat Me 262 jets in December 1944.
