Wiki says
"
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.
Seven two-seat conversion night fighter variants, designated Me 262B-1a/U1,
were available by April 1945. To make room for the radar operator fuselage fuel capacity was sacrificed, and a pair of undernose
hardpoints, one either side of the nosewheel well, for fitment of a pair of standard Luftwaffe 300 litre (79 US gallon) drop tanks were fitted. Following trials with radar fitted to a single-seater the two-seaters were equipped with the mid-VHF band FuG 218
Neptun V radar, with prominent
Hirschgeweih (stag's antlers) eight-dipole aerials on the nose reducing the top speed by about 30 mph.
According to some sources from January 1945 to the end of the war the Me 262's of 10./NJG 11 claimed some 43 Mosquitoes by night and 5 P-38 and Mosquito photo-reconnaissance aircraft by day, although these figures do not tally with known Allied aircraft losses.[SUP]
[2][/SUP] Among them six Mosquitos by
Feldwebel Karl-Heinz Becker and his radio operator in two weeks, two within three minutes of each other on the night of 23 March 1945.
The last kill by III./NJG 11 came on the 21 February 1945, when Obfw Frank in a Bf 109 G-14 shot down a Lancaster near
Krefeld. "
