Likely to stow the landing gear. Note how the wing is in mid-position on this concept.

I immediately thought Kuchemann carrots as well, and also where to stow the landing gear. I'm not convinced that it has a variable-sweep wing. That panel line on the upper surface of the wing might be the fold joint although it doesn't appear that the outer wing panel will clear the carrot/landing-gear fairing when folded. A variable-sweep wing suggests supersonic performance and the rest of the airframe is far from supersonic sleekness. It may have had a semi-sweep wing, forward for loiter endurance and aft where it is in the drawing for high-speed cruise to and from the loiter point, but that seems heavy for that limited a speed range.

Looks like it's simply improving transonic drag so that your critical Mach number was increased and better cruise resulted. It does look like the folding would be iffy. Moving the gear to the carrot would let you keep the gear in roughly the same position while you're moving the wing-root forward. Also might give you more room for fuel if you had wet wings. Sort of a two-birds, one-stone. I doubt it was variable-sweep, though. Doesn't seem worth it.

Just stumbled across this snippet of information re Boeing's Model 835 Missileer design submission

Quote
“Bob Burnham and I were primarily responsible for the external configuration of that airplane [the Boeing Model 835]. We did a lot of wind tunnel testing and also did quite a bit of detail design work on this proposal to the US Navy. Alas, we came in second to Douglas………”

Greetings All -

A few photos early on in wind tunnel testing at the Vought Low Speed Wind Tunnel of the V-434.

Enjoy the Day!  Mark

A long-endurance high-warload missile carrier would be an ideal role for a flying wing.  I guess that Northrop had accepted no for an answer by then though.
By the way, what does BLC stand for?
