On April 11 at US Naval Air Station Patuxent River, Maryland, Navy test aircraft CF-2 carrying external 2,000-lb (907-kg) GBU-31 Joint Direct Attack Munitions (JDAM) and AIM-9X Sidewinder heat-seeking missiles completed the final developmental test flight of the System Development and Demonstration (SDD) phase of the program.
