Lockheed Martin Space Systems has received a $92 million U.S. Navy contract modification for work on the Mobile User Objective System, or MUOS.

The modification to the cost-plus-award-fee contract covers engineering services, interim logistics services, spares and associated material.

MUOS is a narrowband military satellite communications system that supports a worldwide, multi-service population of users, providing modern net-centric communications capabilities while concurrently supporting legacy terminals.

Work will be performed in Arizona and California, with an estimated completion date of November 2018.

The Space and Naval Warfare Systems Command is the contracting entity.
