Until the operational entrance of the Me-110 as the first standard night fighter of the Luftwaffe, different versions from powerfuls FW 190 were used in experimental form to evaluate the operation of the new radar of the FuG series.
Even some Me-109 they were provided with such radars like experimentation versions, like Me 109 G-6/N and Me 109 G-6/Y, used in the IV/NJG2 that took the FuG 350 "Naxos Z" radar.
The versions of FW 190 used as experimental night fighters were the A6, A7, A8 and F; the type of radar used (also the types and location of the Letzler antennas) were FuG 216, FuG 217 and FuG 218. The successes obtained by Me-110 (and later by the Heinkel 219 and the Me-262 B1A/U1) took to the cancellation of the FW 190 night fighter program, although given the necessities, some squadrons continued operating until the end of the war. But by mainly, it must consider that the different versions of Fw 190 were desperately required like diurnal versions than more nocturnal, since they was used not only like bomber interceptor, but for a great variety of other missions.
It was perhaps by that reason that, from half of 1943, was introduced a new night aerial battle tactics: the Wilde Sau or . This strategy created by the bomber pilot Hajo Hermann consisted of which, day fighters turned nocturnal by the addition of radars, were guided at night towards the enemy formation with the help of ground radars. Once produced the interception, each one of the hunters had free election of their prey.
The purely evaluative nature of the NJG 10 explains the differences between the airplanes of the same unit respect to camouflages, radar types, location and types of antennas and until the strategy of attack used. On the matter, one thinks that the Fw 190 A6/R11 WN 550148 "white 11" was of the first night fighters being used successfully in this type of missions.
The emblem of the squadron consisted of a wild boar head (Wilde Sau) with the abbreviation "Jllo", abbreviation of Jägerleitoffiziere (Fighter Control Officer). According to the information that I could find, it seems that this badge was initially the personal emblem of one aircraft commander of the NJG 10, being later adopted like standard identification insignia of all the squadron.
The historical importance of NJG 10 was not given by the successes achieved in combat; non figure in annals of the Nachtjagd like outstanding as far as the number of kills, simply because its function was not to participate openly in combat but to evaluate the different tactics from night fighter that would be carried out by the remaining constituted fighter units for such aim. It is highly probable that these units have benefitted from the tactics contributed by NJG 10.

What was of the "white 11"? I could not find references about the final destiny of the airplane nor its pilot, Oberleutnant H.F. Kraus. A very spread photo shows him arming a cigarette in the horizontal stabilizer of its "white 11" in Werneuchen
The certain thing was that the moral impact that produced in the allies the introduction of the new techniques of German night fighter was so great that they made very popular the emblem of NJG 10, to the point that, even at the present time, some North American squadrons and English electronic war uses the figure of a wild boar like emblem... Volunteer or not, a doubtless tribute to the NJG 10 men.
