The U.S. Navy will gradually introduce new ground-attack weapons to make up for the blank space on the range of the Tomahawk cruise missiles and the MK45 127 mm / 54 gun. In 2003, a Tactical Tomahawk cruise missile with a range of 1,500 nautical miles will be introduced first. In 2004, a supersonic ground-attack Standard Missile (LASM) with a range of 150 nautical miles and a new MK45-4
