Maritime October 19, 2021

Northrop Grumman has delivered the 500th WSN-7 ring laser gyroscope inertial navigation system (INS) to the US Navy.

Beginning with the first gyroscope installed on USS Utah (BB-31) in 1911, Northrop Grumman has built a reputation as an industry leader and partner with the U.S. Navy in navigation, positioning and sensing systems. Today, the AN/WSN‑7 is the U.S. Navy Program of Record for INS on all surface combatants equipped with AEGIS weapons systems (Ticonderoga-class missile cruisers; Arleigh Burke-class destroyers), all Nimitz-class aircraft carriers, amongst other U.S. and allied vessels.

The AN/WSN‑7A is the US Navy Program of Record for all Los Angeles-class, Sea Wolf-class and Virginia-class submarines, and provides the same level of performance and accuracy as the AN/WSN‑7, in a modified form factor fit for subsurface use.

Northrop Grumman’s broad range of assured positioning, navigation and timing (A-PNT) systems provide precise, survivable, secure, resilient and agile solutions for sea, land, air and space.

Todd Leavitt, Vice President, naval and oceanic systems, Northrop Grumman, said: “Installed across the US Navy Fleet, Northrop Grumman continues to support U.S. and NATO surface and submarine naval platforms around the world.”
