We have a 15-year track record of success in providing joint operability solutions for Combatant Commanders. Among the various services we offer to the test and evaluation community is our work to improve the employment of technology in hostile or difficult environments. These efforts have addressed tough problems such as using smart munitions and communication systems when Global positioning data is unavailable, developing procedures for coordinated air defense operations within the U.S., and integrating unmanned aerial vehicles into the national airspace.
