The Bell V-247 "Vigilant", an in-development "tiltrotor" Unammned Aerial System (UAS) concept, was unveiled by Bell Helicopter in September 2016. Its design is intended to satisfy the future vision of United States Marine Corps (USMC) aerial capabilities. As a tiltrotor, the product will incorporated the straightline performance of a fixed-wing aircraft with the vertical take-off and landing capabilities of a helicopter - owing much to Bell's experience with the V-22 tiltrotor product. Such platforms can be used in a myriad of battlefield roles - maritime reconnaissance, offshore resupply of ships, resupply of Forward Operating Bases, target acquisition/tracking, general surveillance and the like.
If the Vigilant program proceeds as intended, serial production is set to begin in 2023.
Helicopters outdo their fixed-wing counterparts by their inherent ability to land on unprepared surfaces, not requiring long distances of runway. This allows them to station on warships or mountain sides and serve in direct contact with forward-operating elements such as infantry. The lack of a pilot and crew means no loss-of-life when operating in hostile, contested areas. A built-in long-endurance quality provides for long operational ranges and increased loitering times - factors typically limiting fuel-thirsty, fast-moving fixed-wing aircraft.

April 2022 - Bell unveiled a reworked, dimensionally-smaller maritime version for the USN of its V-247 tiltrotor system. As proposed, the aircraft would have a 28,000lb weight and folding main rotor blades for storage.

Mainplanes are mounted at the upper-most position allowable along the dorsal line of the fuselage.
The planform involves use of basic, straight mainplane members.
(Structural descriptors pertain to the base Bell V-247 Vigilant production variant)
1 x Single unit propulsion system driving power to 2 x 30-foot diameter tiltrotors on wing mainplane.
None. Mainly ISR (Intelligence, Surveillance and Reconnaissance) payload up to 600lb. Proposed support for Mk-50 series torpedo, Hellfire Anti-Tank Guided Missile (ATGM) and new-generation Joint Air-to-ground Missiles (JAGMs) in internal bay.
