The Department of State has cleared a potential foreign military sale to the United Kingdom for Navy multiband terminals and related equipment valued at $200 million, with RTX named as the principal contractor.
What Will the UK Receive Under the FMS Deal?
According to the Defense Security Cooperation Agency, the U.K. FMS request covers six additional advanced extremely high frequency NMT, expanding a previous FMS case, valued at over $41 million, to a total of eight AEHF systems. The package also includes communications security devices, submarine high-data-rate masts, ancillary hardware, containers, spares, training, integration support and logistics services.
How Will the UK Use NMT?
DSCA said the Royal Navy plans to install the terminals aboard Dreadnought-class submarines to provide protected AEHF satellite connectivity between vessels and Ministry of Defence shore sites in a non-contested threat environment.
The sale advances U.S. foreign policy and national security objectives by strengthening a key NATO ally and enhancing interoperability across coalition operations. The U.K. is expected to absorb the systems without difficulty.
What Is the Navy Multiband Terminal?
The NMT is the Navy’s next-generation maritime satellite terminal designed to provide secure, resilient, protected communications over the AEHF constellation. System variants support ships, submarines and shore nodes, enabling high-capacity, beyond-line-of-sight data services for joint and allied operations.
