Defense contractors Lockheed Martin and Northrop Grumman said Thursday that they've won a $91 million contract for radars to be used on Saudi Arabia's Apache attack helicopters.

Northrop Grumman said its share of the Longbow work would be handled from its electronic systems division in Linthicum. Lockheed Martin is based in Bethesda.

The companies said the contract is for Longbow Fire Control Radars for the Royal Saudi Land Forces Aviation Command and the Saudi Arabia National Guard, spares and support for the aviation command and Longbow mast mounted assemblies for the U.S. Army.
