Lockheed Martin has delivered the first five Sentinel A4 radars to the STARE Project Office of the US Army Sentinel Product Office, in line with an accelerated schedule.
The Sentinel A4 is billed as a high-performance air and missile defence radar, designed to enhance protection against cruise missiles, unmanned aerial systems, rotary wing and fixed wing threats.
The Sentinel A4 variant is also capable of detecting rocket, artillery, and mortar (RAM) threats.
Lockheed Martin was first tasked with delivering the systems to the US Army in September of 2019 and has since completed a System Requirements Review/System Functional Review (SRR/SFR), Preliminary Design Review (PDR), and the Critical Design Review (CDR).
“We are one step closer to getting this enhanced capability to our warfighters,” Leah Cook, Sentinel product director for the US Army Sentinel A4 program office, said.
“The delivery of the first five radars is a result of collaboration and a continued commitment to the US Army.”
Mark Mekker, director of army radars at Lockheed Martin noted the “criticality” of the system.
“Our soldiers are in unpredictable environments, and the Sentinel A4 will provide improved eyes on the field to keep them safe,” he said.
Lockheed Martin is now expected to support the Army in the government test program phase into early 2023.
This is set to involve mobility, environmental, radar performance and logistics testing.
The next five radar systems are currently in production, with delivery scheduled in March 2023.
