L-3 Communications (NYSE: LLL) announced today that its MariPro division has been awarded a multi-year contract with a potential value of $127 million, if all options are exercised, to install an Undersea Warfare Training Range off the coast of Jacksonville, Fla., for the U.S. Navy. The scope of this contract includes design, manufacturing and installation of a state-of-the-art undersea warfare training system that will ultimately span 500 square nautical miles. Phase I of the program will provide the initial infrastructure, including shore facilities and equipment, as well as near-shore cable and seabed sensors to instrument an area of approximately 200 square nautical miles. The second phase of the program will instrument the remaining 300 square nautical miles. The installed system will provide the U.S. Navy with the latest technology to maximize training and testing, particularly in shallow water. The system has a 20-year design life. “This is an exciting win for our group as we continue to focus our business on priority DoD areas,” said Robert E.
