Nothing past A9/A10 concept existed at all. The A11/12/13/14 aren't mentioned in any wartime sources or archives, and known only from Von Braun words. It's highly likely that Von Braun invented those "rockets" post-war, to present himself as even more valuable (he really feared that Americans would gave him to British - who wanted to try him as war criminal - and he was afraid that A4 would not be impressive enough to save his life). The whole designs are utterly hare-brained, and the "manned" guidance is just absurd (Von Braun wasn't guidance specialists, but he likely realized, that intercontinental missile without ANY guidance would looks too dubious to persuade anyone. So he invented the idea of missile being manned)
The V-1 missile was to be used in
Pulkzerstörer (formation destroyer) against enemy bomber streams steered by a new DFS radio-command from a Fw 190 pilot.
In 1943 it was proposed to build a television-guided version to compete with the Henschel Hs 293D missile, but in 1945 the Allies electronic technology was so advanced that they could interfere any German radio-control system.
Only those who could be fitted with primitive wire-guidance devices, like the flying bomb Henschel Hs 293 A, the air-to-air missile Rhursthal Kramer X4 or the X7 antitank rocket of the same firm survived. But the results achieved in combat using these systems were not too good; sometimes the cable broke or lacked the necessary length to avoid the effects of the naval AA, with the dangerous disadvantage that the launcher plane was forced to fly on a straight line while guiding the missile.
After the failure of the Messerschmitt Me 328
schnellbomber, the Germans realized they lacked the means to stop the Allied invasion that they expected would take place in the sector of Calais by mid-1944. In May of that year the first
Mistel composite-bombers entered service, but they could only be used against static targets because during their final dive they were controlled by an automatic pilot only.
The Axis only possibility was using suicide pilots.
By mid-1943, Hanna Reitsch, who had participated in the testing program of the Messerschmitt Me 328, piloting one of the prototypes and was greatly affected by the bombing of German cities, met with Otto Skorzeny and Erich Lange to support his idea of using a piloted version of the V-1 as a last-ditch weapon.
In August 1942, a group of former glider pilots of the
Sturm Abteilung Koch meeting in a Berlin Flying Club had conclude that the
Ballistikfrei piloted glider-bombs were the only weapons that could guarantee the German victory. Known unofficially as
Reichenberg Commitee, this group of radical ideas that was represented before the Führer by Hanna Reitsch was gaining influence with each defeat of the
Wehrmacht in Russia and Africa, with each U-Boat sunk in the Atlantic and with the devastation of Hamburg by Allied bombers.
In November 1943 the S.O. concept was discussed by technicians, scientists and
Luftwaffe officers during a secret conference at the
Akademie der Luftahrtforschung, under the leadership of Adolf Baeumker.
