Steam from the catapult surrounds an aviation ordnanceman as he gives a thumbs up after checking a Joint Direct Attack Munitions (JDAM) attached to an F/A-18C Hornet before launching from the USS Kitty Hawk (CV 63) on Aug. 22, 1999. The Hornet will be releasing the JDAM at the Okinawa, Japan Range Area in the first fleet squadron drop of the newly developed weapon. JDAM uses a global positioning system aided inertial navigation system to guide its 2,000 or 1,000 pound warhead to the target with a high degree of accuracy. The Hornet is attached to Strike Fighter Squadron 195 of Naval Station Yokosuka, Japan.
