Bell Helicopter has unveiled a unmanned tiltrotor aircraft, the V-247 Vigilant, as it looks towards a future requirement from the US Marine Corps for a large, armed platform capable of operating from ships.

Bell says "blade fold, wing stow."  Judging from the illustrations, I suspect the wing rotates to lie parallel with the fuselage like the V-22.  The dihedral wing segments outboard of the rotor nacelles probably would fold up and in to reduce length overall.  To fit in a DDG-51 hangar, it has to get down to roughly 41 feet length folded.

Edit: Confirmed.

The V-247 will be sized to fit on the deck of a guided missile destroyer, Tobin said. By folding its rotor blades and stowing its wing by swiveling it across the top of the fuselage lengthwise, it could fit inside a DDG’s helicopter hangar. On a stand to Tobin’s left as he spoke stood a big 1/8th scale model of the V-247 – far larger than the one we saw on Lt. Gen. Davis’s desk last month – automated to fold its rotor blades and stow its wing to demonstrate shipboard storage. Bell is expected to display the model at the Sept. 27-30 Modern Day Marine exposition at Quantico Marine Base, and at the Association of the United States Army’s annual meetings Oct. 3-5 in Washington.

So was the V-247 Bell's DARPA TERN entry?

Big thread on this in Postwar Aircraft Projects.

Could you explain why the thread is there?

I would think that there is likely to be a very close connection, at the very least.

Folks stated two threads last time the topic came up and they got merged to the Postwar Projects subforum.  You'd have to ask a moderator why.

Well, the V-247 is currently a "project," and "now" is currently "post-war." So, "post-war projects" sure sounds like the right place for it.

Well I think this new aerospace project that was developed post WW2 should be put in the hypotheticals since it is nothing more than engineering programs and pretty picture. 😋

Basically, "Aerospace - Aerospace discussion on any topics you like - not unbuilt projects"
When project will move to prototype stage, will gain funding - it will probably be moved to Aerospace. It all depends, though.

Bell says it did not bid for Tern. Also, Tobin says the V-247 is bigger than Tern. But the US Marine Corps aviation master plan uses Northrop's coaxial-rotor tailsitter Tern to illustrate the MUX - MAGTF Unmanned Expeditionary - capability that Bell is aiming at, so it represents the competition.

Well these are the compromises you have to make to fit on a warship. Or you go the TERN route.
