CHARLOTTESVILLE, VIRGINIA — Northrop Grumman Corp., the Charlottesville, Virginia, defense contractor, received an $18.1 million contract modification to build inertial navigation sensors for the U.S. Navy and two allied governments, as announced on war.gov.

The firm-fixed-price award exercises options under a previously awarded contract, N00024-23-C-5234, to manufacture surface and submarine inertial sensor module configurations and support equipment for the IWS 6 Navigation program. The order splits purchases among the Navy at 23%, the government of Canada at 44%, and the government of Australia at 33%, under the Foreign Military Sales program, according to war.gov.

Inertial sensor modules measure a vessel’s motion and orientation without relying on external signals, letting ships and submarines navigate when satellite positioning is jammed or unavailable. That capability matters most for submarines, which stay submerged and cannot surface to fix their position.

The modification marks the sixth contract to Northrop Grumman in 2026 and lifts the company’s total contract value for the year to $1.6 billion, according to war.gov. It stands well below the company’s largest recorded award of $1.2 billion. Within the 2026 Navy portfolio, the deal falls between a year-to-date minimum of $9 million and a maximum of $8 billion, according to war.gov.

The deal spreads work and money across allies and states. Canada carries the biggest share with $8 million in Foreign Military Sales funds, and Australia contributes $6 million, according to war.gov. Navy procurement funds cover the remaining $4.1 million. The distribution ties the navigation programs of three militaries to a single supplier and a single production line.

Most manufacturing stays in Charlottesville, Virginia, at 84% of the work, with the rest divided among Salt Lake City, Utah, at 14%, Woodland Hills, California, at 1%, and Baltimore, Maryland, at 1%, according to war.gov. The award marks the 22nd Department of Defense contract placed in Virginia during 2026, reinforcing the state’s role as a hub for naval systems work.

For most Americans, the contract has no direct effect on daily life. It reflects the routine machinery of allied defense spending, where U.S. contractors equip partner navies and share the cost of production runs that would otherwise fall entirely on the Pentagon.

This type of award has happened before. Foreign Military Sales cases regularly fold allied purchases into U.S. Navy contracts, and Northrop Grumman has repeatedly received option exercises on the same base contract to keep sensor production running.

Naval Sea Systems Command, based in Washington, D.C., serves as the contracting activity and will oversee performance, according to war.gov. Work should conclude by February 2029, and the Pentagon has not announced a date for any further option decision on the contract.

Naval navigation has driven technology races long before satellites existed. The Navy funded the Ships Inertial Navigation System in the 1950s to guide the first ballistic-missile submarines, which needed precise position fixes to launch accurately while submerged. That work fed the guidance breakthroughs behind the Polaris missile program, and it turned inertial navigation into a permanent pillar of undersea deterrence that contractors still supply today.

This contract represents the 6th contract awarded to Northrop Grumman Corp., in 2026, bringing the company’s total contract value for the year to $1,610,341,344. It is also the 22nd Department of Defense contract awarded in Virginia during 2026. While this is not the largest contract ever awarded to Northrop Grumman Corp., whose record stands at $1,196,000,000, it is notable within the Navy portfolio. Specifically, it falls between the 2026 Navy portfolio’s year-to-date minimum of $9,046,496 and maximum of $8,000,000,000. Overall, this award was announced among 16 Department of Defense contracts issued nationwide on July 31, 2026.
