MBB Lampyridae one more time

Earlier this month there was an interesting thread about the Lampyridea. It
took me some time to locate my research material, hence this delayed
contribution.
I too have collected material about this aircraft for years. My interest was
awakened last year when I heard that two scale prototypes have turned up, at
the Berlin-Gatow Luftwaffe Museum and the F-104 Museum in Niederalteich. I
found one rather obscure source of information, that contained two interesting
drawings. The source is 'RCS Determination for DLR Stealth Design F7',
published in 'Non-Cooperative Air Target Identification Using Radar, Meeting
Proceedings', NATO RTO (formerly AGARD I believe). Compared to the Flug Revue
and Jane's drawings, it has three extra facets on each side of the rear
fuselage:


The paper is listed here on the CV-page of one of the authors:


If you search for 'DLR F7' you will find the following pages:

(this German-language page
refers to the F7 and refined F10 configuration)
(Google found reference to
the F7 design in this PDF, which you can only be downloaded by subscribers or
by paying for it.)

So much for my findings!
