Lockheed Martin has received core structural components for an Air Force geosynchronous satellite, the firm announced Thursday.
The Bethesda, Md.-based defense and technology firm said it received the structure for the missile warning satellite at its Mississippi-based space and technology center.
Production of GEO-3 and GEO-4 is on schedule, said Louie Lombardo, director of Lockheed’s SBIRS follow-on production program.
The fourth satellite in the Space Based Infrared System is scheduled to launch in 2015, the company said.
Program team members will begin to integrate the satellite’s propulsion subsystem, after which Lockheed said it will ship the system to Sunnyvale, Calif. for final assembly, integration and testing.
In April, the company said it is preparing the GEO-2 to potentially launch in July and that satellite launches may continue through 2016.
