Northrop Grumman Corp. received a $9.3 million contract from the U.S. Naval Air Systems Command to supply computers for the improved models of the H-1 helicopter.

The computers are made by the Woodland Hills-based Navigation Systems division of Northrop Grumman. Deliveries are expected to be completed by January 2015.

The mission computers will be used onboard UH-1Y and AH-1Z helicopters that make up the Marine light attack helicopter squadrons. Those aircraft will replace aging AH-1W and UH-1N helicopters.

The computers provide centralized control of the avionics systems, interface with the tactical moving map and display both situational awareness and health monitoring information.

“The high-performance mission computers have proven their reliability and superior value supporting ongoing missions such as Operation Enduring Freedom in Afghanistan,” said Ike Song, vice-president of Northrop Grumman’s situational awareness systems unit, in a prepared statement. “They offer advanced computing and video processing capabilities to help ensure pilot safety.”
