But no on the A11.
Dieter Hoelsken, documents this in V- Missiles of the Third Reich*,
monogram Aviation Publications, 1994. There is a document at the
Bundesarchiv (Military) dated 1943!, that describes the A11, in fact a
theoretical model for a A9/A10/A11 was calculated. See the note of
page 256 of Hoelsken's book, and footnote 52.

In the Monogram Books edition, it's on page 265 and footnote #52.

By the by , Hoelsken publishes a drawing of the piloted A9 on page 264
of V- Missiles of the Third Reich, but gives no historical
documentation.

It's the only known wartime drawing of the manned A-9 variant; it was
supposed to be used as a reconnaissance machine. It's also shown in
G.Harry Stine's "ICBM" book.
The cutaway drawings of the manned A-9/A-10 on the site you supplied
link to are from "Secret Wonder Weapons of the Third Reich" by J.
Miranda and P. Mercado of Spain; they sure look impressive, don't they?
The cutaway drawings of the Nazi flying saucers in the hideously
overpriced "German Circular Planes "(Dossier # 10) by the same team also
look impressive:

does the drawing of the Windkanone firing at the wrong end in their also
way-too-expensive "Strange Phenomena in the German Sky" (Dossier #11);
the art is great- but one must be very wary of the content. The "Archiv"
drawing of the manned A-9 reminds me in its style of a drawing that was
published of the speculated Soviet variant of the Antipodal Bomber, and
I suspect comes from the same source; if that is the case, it dates from
the early 1950's.
