Martin snares sonar pact


Bethesda-based Martin Marietta Corp. said today it has received a $19.3 million contract from the Navy to make vessel-detecting sonars for Canada and Spain.

The three-year contract calls for eight "towed array" sonars and parts as well as $500,000 in options. Production should begin at the end of the year at the company's Glen Burnie facility.

The sonars, actually sensitive listening devices, are towed behind ships and submarines to detect other vessels.

Martin also has received a $5 million contract from Lockheed Corp.'s Lockheed Space & Missiles Co., for production of Trident II submarine missile parts.

The initial contract is to produce four nose cones and other missile parts for demonstration purposes. Some of the parts will be constructed out of thin layers of Sitka spruce plywood.

The work will be performed at the company's Middle River plant by September 1992. At the conclusion of the demonstration, Martin Marietta said, it could receive production follow-up contracts reaching $80 million.

Neither contract is expected to result in hiring.
