US Marine Corps Fields Northrop Grumman Modernized Bell Helicopter H-1s
The U.S. Marine Corps has started fielding modernized Bell Helicopter H-1s. Aircraft under the H-1 upgrade program have been outfitted with the technology as the Marine Corps recently fielded the equipment for the first time.
Northrop Grumman said the mission computers were installed on the UH-1Y and AH-1Z under the upgrade program. It aims to replace UH-1Ns and AH-1Ws with upgraded aircraft. This would improve capability, commonality, reliability and maintainability, according to Northrop Grumman.
Tech Refresh Mission Computer is now in full-rate production. It features multi-core processing, integrating advanced mission, weapons and video processing capabilities into a conduction-cooled airborne computer. The computer can drive four independent, multi-function displays.
According to Steve McCoy — VP of land and avionics command, control, communications, computers, intelligence, surveillance and reconnaissance (C4ISR) division at Northrop Grumman Mission Systems — the computer gives aircraft “an asymmetrical advantage and improved situational awareness” due to its processing C4ISR capabilities.
“This next generation of centralized mission computing will accommodate future growth and rapidly bring emerging capabilities to the warfighter through its proven open system architecture,” McCoy said.
According to the company, dual mission computers are central to its integrated avionics system powering the helicopters. They provide centralized display and control of all IAS functions, including aircraft performance and flight instruments, onboard sensor and survivability displays, and improved situational awareness and health monitoring information. Both the UH-1Y and the AH-1Z have identical mission computers.
Northrop Grumman said its scalable and fully integrated architecture supports other aircraft, including the Sikorsky UH‑60 and Northrop Grumman E‑2D. H-1s have used Northrop Grumman’s mission computers since the upgrade program started in 1997, the company said.
