...more info. of the Ju 290:
At least one of the five long-range reconnaissance aircraft of the A-4 series was used for glide-bomb testing with the Hs 293 and Fritz X controlled by the Kehl radio-control system. The A-5 series, which followed at the end of 1943, had two ETC 200 bomb racks and an additional nose-mounted MG 151/20. Eleven A-5s were produced.
In early 1944, tests of the Ju 290 A-7 began. This aircraft had a stronger airframe, the glazed nose of the A-4 as standard, seven MG 151/20s and one MG 131, and movie cameras for sideways photography. A capability for carrying guided bombs was also planned. Max. speed of this verson with BMW 801 Ds was 438 km/h at 5000m altitude, and factory data gives the range as 5 800 km. Fourteen A-7s were built at the Junkers works.
A single Ju A-8(Works No.0212) was planned as a spec. Bomber, but it was in Prague-Rusin in May 1945, it could not be produced.
The Ju 290 A-9 had two hydraulically-operated turrets with four MG 151/20 machine guns and an improved tail-gun position with two 151/20s. It´s max. bomb load was 3000kg, and flight characteristics were simular to those of the A-7. About fifty Ju 290s were manufactured up to the end of production in the summer of 1944.
The Ju 290 B-1 series was intended to be massproduced with additional four-gun position at both nose and tail. Construction of the B-1 began in September 1943, but experience with FAG 5 showed that the defensive armament was inadequate. The prototype of the B-1 was inspected on 16 Oktober 1943, but the remote-controlled gun positions did not gain the approval of either the RLM or Erprobungskommando Garz. Work on the 290 B was eventually stopped on the 30 June 1944.
