The Naval Information Warfare Systems Command intends to award a sole-source contract modification to Raytheon Company for engineering services to upgrade the Navy Multiband Terminal for interoperability with the U.S. Space Force's new satellite constellation. The modification increases the contract ceiling by $352.39 million. The prime contractor, Raytheon, is located in Marlborough, MA. This is a notice of intent and not a request for competitive proposals, though the government may consider responses from interested parties. The period of performance for the underlying contract, which includes options, can extend until September 2035.
