From:

Report Of The General Board, United States Forces, European Theater.
V-2 Rocket Attacks and Defense.
Uncertain of date but stamped Library Apr 3 1952 Army War College. Also marked Antiaircraft Artillery Section Study Number 42.

J. The A-9 was similar in appearance and results to the A-4b, but was of different internal construction. It was proposed to develop and manufacture the A-9 in place of the A-4. However, the conversion would have been difficult, and the A-4b, which could be produced much more quickly, was being developed as a temporary substitute. The plan was to shoot the missile vertically into the air and then incline it toward the target. Its design included wings to enable it to glide until over the target, where it would go into a vertical dive. It was expected to travel about 375 miles (its maximum range) in 17 minutes. A proposal was made to launch it from a catapult to increase its range. It was also proposed to install a pressurized cabin, and to use a human pilot. The pilot would drop the warhead on the target, and then return to his base. A retractable landing gear would be used in the landing. Landing speeds as low as 100 miles per hour were inticipated.

K. The A-10 was never built, but plans for its production were completed. It was to be used as a take-off motor for the A-9, supplying a 200-ton thrust for this purpose. When the A-9 attained a velocity of approximately 1,500 miles per hour, its own motor would begin to function, and the A-10 would be jettisoned. It was expected that the A-9 would then attain a velocity of about 3,360 miles per hour and a range of about 3,500 miles.It was also proposed to use a human pilot in this combination.

"indeed i had doubted them myself til now!"

There's no need to doubt, that there were such ideas. But there still is a difference
between having an idea and being able to realise it. "Report Of The General Board,
United States Forces, European Theater", that sounds very much like results from
interviews and interrogations, to my opinion not the most reliable source. To make a
sketch of a piloted V2 is one thing, it not even would have been hard, to make detailed
drawings, but actually building this thing, launching it and bringing it back with its pilot
alive would have been a whole new ball game !
Reading about such themes, I always have the strong feeling, that many still believe, things
like the piloted V2, A9/A10 or maybe supersonic jets were just around the corner in 1945.
A healthy lot of fundamental research would have been needed, and if you look to post-war times,
when comparable projects actually were realised, you can get a feeling of the needed time-
frame. From the very beginning of the war, the german industry simply wasn't able to develop
such things, that means to bring such ideas to realisation in a reasonable time. The capacities
for engineering and research already were already overstressed for bringing the more conventional
weapons to the front.
One of the main reasons for the defeat of Germany was that its economy in relation to that of
the US was like a middle sized workshop compared to factory. The craftsmen in that workshop
may have many ideas, when drinking a beer in the pub at the end of the work day. But when they
try to realise them, they may get whipping !

I'm not saying that I believe what was in this particular report as I think it was compiled from others. What I found intriguing was the mention of the catapult ;)

a question to archipepe drawings ---

i always understood the the engine of the A10 to consist of a number of A4 engines (as "preburners" / injectors - probably running overly lean and fat alternately) exhausting into a mixing / main combustion chamber ..

if that understanding is correct, i believe the size of the "preburners" of the A10 engine is wrong when compared with the A4 engine of the A9 ..

As far I know, this was the initial intention of the German designers (Walter Thiele before his death).
But the design changed after resulting in a single combustion chamber as represented.
Taking into account that all the drawings I saw depicted the engine in that way.

If someone has more infos about that will be very welcomed.
