U.S. NAVY TOMAHAWK MISSILE LAUNCHED IN TEST FLIGHT, NOV. 13

 U.S. NAVY TOMAHAWK MISSILE LAUNCHED IN TEST FLIGHT, NOV. 13
 ST. LOUIS, Nov. 20 /PRNewswire/ -- A U. S. Navy Tomahawk sea- launched cruise missile with Block III system improvements was launched in a flight test on Nov. 13. The test marked the first Tomahawk Block III flight with a live WDU-36B warhead.
 The missile was vertically launched off the coast of California from the USS David R. Ray. The target was a building located on San Clemente Island, 50 nautical miles off the coast of Los Angeles. The Tomahawk missile completed its mission with a terminal dive into the target.
 The WDU-36B is a new insensitive, extended-range warhead developed by the Naval Weapons Center that is smaller but as lethal as the 1,000-pound bullpup warhead used in existing conventional land-attack Tomahawks. Because the warhead is smaller, additional fuel can be stored around the warhead, which extends the range of the missile.
 Tomahawk Block III upgrades were developed by McDonnell Douglas Missile Systems Co. for land-attack Tomahawks that are equipped with either a single warhead or a submunitions warhead. These product improvements include the addition of a Global Positioning System (GPS) receiver and antenna; an upgrade of the Digital Scene Matching Area Correlator (DSMAC-IIA); time-of-arrival control; and a new payload section.
 GPS supplements the current Terrain Contour Matching (TERCOM) system as an alternative means for missile navigation. DSMAC-IIA provides additional computing power and software to improve operational flexibility.
 Time-of-arrival control allows the Navy to predesignate the arrival time of Tomahawk land-attack conventional missiles at the target. This capability will allow for improved coordination with air strikes.
 The Block III upgrade will provide a significant increase in range and greater mission planning flexibility to the conventional land-attack variants of the Tomahawk. It will also increase the weapon system's utility and responsiveness.
 All Tomahawk conventional land-attack variants are capable of being fully remanufactured to a Block III configuration.
 Engineering and development of the Block III upgrades are performed by McDonnell Douglas Missile Systems Co. in St. Louis. The Missile Systems Co. produces the Tomahawk at its Florida Missile Production facility in Titusville, Fla.
 McDonnell Douglas (NYSE: MD) has been building missile systems for the Department of Defense for more than four decades and has delivered more than 100,000 guided missiles to DoD customers.
