National Security Space
Enhancing national security through the application of space science and technology
TacSat-4 Successfully Launched
TacSat-4 was successfully launched September 27, 2011, from the Kodiac Launch Complex, Kodiak Island, Alaska. The spacecraft bus was built by NRL and APL to mature ORS bus standards. It was developed by an Integrated (government and industry) Systems Engineering Team.
Programs in APL's National Security Space Mission Area focus on space solutions to critical military challenges. We develop and conduct innovative experimental missions, build space instruments, and produce new applications to meet warfighter needs. We offer innovative engineering, advanced technology development, and a deep-rooted systems engineering culture. Significant experience in both civil and national security space programs means we leverage capabilities and accomplishments from NASA programs to address national security space capability gaps and needs. As part of a Department of Defense (DoD)-sponsor-based organization, our National Security Space work also benefits from synergy with other APL mission areas.
