TM Systems has been awarded a contract worth $2.1 million to supply two Stabilized Glide Slope Indicator (SGSI) systems to National Steel and Shipbuilding Company (NASSCO). The SGSI systems will be used by NASSCO on ships being constructed for the U.S. Naval Sea Systems Command (NAVSEA). These systems are becoming a critical component for the Navy as they allow helicopter pilots to land safely on ships at sea at a time when the Navy needs increased flexibility to engage in military maneuvers from international waters rather than continuing to depend on foreign states to provide landing permissions or allow U.S. military installations.
