The recent Navy League show in Washington was dominated, at least visually, by the DD-21 program, and particularly by a massive full-size mockup of its 155-mm gun, in a housing shaped to minimize radar cross-section. United Defense, which has long been responsible for U.S. naval guns (many of them under the earlier name of FMC), displayed a variety of shells, including a mockup of a guided shell with a millimeter-wave seeker. Lockheed Martin showed a naval version of the global positioning system (GPS)-guided multiple launch rocket system (MLRS) that it has developed for the Army (but which the Army seems unlikely to buy). The rocket can be quad-packed in a standard Mk 41 vertical launcher cell. The company also displayed a first model of the advanced land-attack missile it hopes to sell the Navy.
