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.
