Northrop Grumman received a contract from the US Navy (USN) at the end of December 2022 to perform the initial engineering service for the AN/WSN-12 Inertial Navigation System (INS) sensor packages full-rate production, according to Rudy Fernandez, director, Maritime Systems & Integration, Northrop Grumman.

“We hope to work out with the navy to get out a full-rate production order in the next couple of months,” Fernandez told Janes during a 5 January briefing in advance of the Surface Navy Association (SNA) national symposium held from 10 to 12 January.

“We developed the prototype,” he said. “We developed the EDM [engineering demonstration model], and now we're in transition from low-rate initial production (LRIP) to full-rate production.”

He added, “We delivered the first of LRIP systems, and the first installation on a ship is expected to occur in March-to-April timeframe.”

The installation will likely be on a Flight IIA guided-missile Arleigh Burke-class destroyer.
