PMA-234 Marine Air-Ground Task Force EW Team Lead Bill Mellen said the typical, externally mounted pod was not an option because the MV-22 tilt rotor aircraft does not have traditional wing stations from which to mount podded payloads. The AN/ALQ-231(V)4 IT II system’s upgraded design consists of a roll-on/roll-off rack-mounted payload, controlled from a laptop in the aircraft cabin.

The IT II is a precision, on-demand, EW weapon system designed to provide Marine Corps fixed and rotary wing aircraft with an organic, distributed, and networked EW payload that can be controlled from the cockpit or by a ground operator.

The (V)4 system design will include state-of-the art upgrades, utilizing government and commercial-off-the-shelf technologies and jammer techniques that will allow the Marine Corps to keep pace with the ever-evolving threats on the battlefield, and provide the needed adaptability to allow for future iterations of expanded frequency coverage and advanced capabilities, said Mellen.

Following successful integration on the MV-22B, the IT II team will further expand the V4 design to include a counter-radar capability on the KC-130J aircraft, hoping to leverage much of the MV-22B technology, including the in-cabin rack-mounted payload design, Mellen said.

The IT II (V)4 is scheduled to begin fleet deliveries for the MV-22B in Fiscal Year (FY) 2023 to achieve Initial Operating Capability by the end of FY24 with an inventory objective of 42 total systems.

The IT II (V)1 is flown on the AV-8B Harrier, F/A-18 A++/C/D Hornets, and KC-130J aircraft, while the IT II (V)3 is flown on the UH-1Y Huey helicopter.

The Bell Boeing V-22 Osprey is an American multi-mission, tiltrotor military aircraft with both vertical takeoff and landing (VTOL) and short takeoff and landing (STOL) capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.

The V-22 can be armed with one 7.62×51mm NATO (.308 in caliber) M240 machine gun or .50 in caliber (12.7 mm) M2 machine gun on the rear loading ramp. A 12.7 mm (.50 in) GAU-19 three-barrel Gatling gun mounted below the nose was studied.

BAE Systems developed a belly-mounted, remotely operated gun turret system, the Interim Defense Weapon System (IDWS); it is remotely operated by a gunner, targets are acquired via a separate pod using color television and forward looking infrared imagery. The IDWS was installed on half of the V-22s deployed to Afghanistan in 2009; it found limited use because of its 800 lb (360 kg) weight and restrictive rules of engagement.
