The Pentagon has officially canceled the Global Positioning System Next-Generation Operational Control System (OCX), a 16-year, multibillion-dollar effort to modernize the command and control system for the U.S. military's GPS satellite navigation network. Defense acquisition executive Michael Duffey made the termination decision on Friday, April 17, citing "insurmountable" enduring problems. Originally awarded to Raytheon (RTX Corporation) in 2010 with a $3.7 billion budget and 2016 completion date, the program's projected costs ballooned to nearly $8 billion, and its schedule was extended by a decade. Despite RTX delivering the system last year, further testing revealed it was still not ready and presented risks to current GPS capabilities.
