VX-31 operates one Bell Helicopter Textron UH-1Y “Venom” in support of developmental tests involving both UH-1Y specific and non-specific projects. 
The UH-1Y was designed to replace the USMC's aging fleet of UH-1N Twin Huey light utility helicopters first introduced in the early 1970s.

The UH-1Y is a twin-engine, twelve place, medium-size utility helicopter capable of operating from prepared or unprepared landing areas, amphibious shipping, other floating bases, and austere shore bases, day or night, in VMC or IMC.
The Yankee is part of the U.S. Marine Corps' H-1 upgrade program and shares 84% commonality with the AH-1Z attack helicopter. The helicopters have a common four-bladed, composite, hinge-less and bearing-less main rotor system and tail rotor, engine, avionics, software, controls, and displays.

The primary mission of the UH-1Y is that of a tactical utility helicopter capable of high-speed and low-level flight, multiple weapon fire support, and troop helicopter support. The missions of the aircraft include: sea and air deployment operations; air assault operations; amphibious assault and raid operations; fire support; close air support; interdiction operations; air-to-air operations; coordination of battle space maneuver and integration with firepower; joint personnel recovery; rear area security; and non-combatant evacuation. The UH-1Y has a combat radius of 130 nmi. Mission altitudes range from 0 to 10,000 feet with airspeeds from
0 to 170 knots.

The new fully integrated glass cockpit is night vision goggle (NVG) compatible using AN/AVS-9 NVG's on the Optimized TopOwl helmet mounted sight display. The two crew stations are nearly identical with pilot or copilot functions at either station. The aircraft boasts an integrated avionics system which includes controls, cockpit displays, communications, navigation, central mission computer and external stores and weapons management system.

The Comm/Nav Upgrade aircraft has a communications suite that includes three FM/VHF/UHF AN/ARC-210 radios, COMSEC, an APX-123 IFF identification friend or foe, a satellite communications interface with a high power amplifier and tactical data modem. The upgrade is also equipped with a primary navigation system that has an embedded GPS/INS with an ARN-153 TACAN system and VHF/UHF direction finder. The cockpit is equipped with a digital map for navigation, threat display and in-flight mission planning.

The weapon systems include a variety of 2.75-inch rockets, the M-240D,
.50 caliber GAU-16 and 7.62 GAU-17A door mounted machine guns.
The GAU-17 can be fired in the fixed forward position.

Advanced Electronic Warfare Self Protection (EWSP) suite including AN/APR-39B (V)2 Radar Warning Receiver, AN/AVR-2A Laser Warning Receiver, AAR-47 Missile Warning Device, and AN/ALE-47 Countermeasures Dispensing System capable of carrying up to 60 expendables to protect it from a broad range of modern threat weapons.

A FLIR Systems BRITE Star thermal imaging and laser designation system is mounted under the nose of the aircraft. BRITE Star consists of a triple field-of-view thermal imager based on a three to five-micron focal plane array, a high-resolution CCD TV camera, and laser designator/range finder system (LDRS) for laser precision guided munitions (L-PGM) guidance and accurate target coordinate determination.
