The expanded use of the system will enhance the capability of U.S. forces to quickly rescue downed pilots or combat forces.
"Boeing is extremely proud of achieving this major CSEL production milestone," said Boeing CSEL Program Manager Steve Capps. "Our goal is to continue quality production of the CSEL systems and rapidly provide this critical, life-saving capability to the warfighter."
CSEL, first authorized for use in-theater by U.S. Central Command in 2005, was developed by Boeing. The network-enabled, multifunction radio system allows rescue teams to precisely locate isolated personnel by using multi-satellite, over-the-horizon secure communications and Global Positioning System.
The system provides real-time communication capabilities and enhanced coordination with isolated personnel.
The CSEL system is the U.S. Department of Defense's program of record for combat search-and-rescue communications.
The radios are available to other U.S. government service branches through the General Services Administration.
