Serco has won a new indefinite-delivery/indefinite-quantity (IDIQ) contract to continue supporting the US Navy’s Submarine High Data Rate (SubHDR) antenna systems.
Under the single-award contract vehicle which has a ceiling value of US $97 million (£72 million), Serco will provide maintenance, repair and upgrade services for the SubHDR Antenna Pedestal Group, a mission-critical system which enables the US naval fleet to send and receive information, such as secure wide-band communications, voice and data traffic, imagery and video conferencing.
The group has supported the SubHDR programme for over 20 years, and the new contract extends this support by 10 years.
Work will primarily take place at Serco’s production and repair facility in Ludlow, Massachusetts, with support services also taking place in Newport, Rhode Island.
Anthony Kirby, Serco Group Chief Executive, says: “We are delighted to continue our support for the US Navy’s SubHDR systems, which provide a critical communications capability to the US fleet.
[W]e are honoured to have been selected to help the US Navy maintain its competitive edge over the next decade.
This recompete reflects Serco’s extensive capabilities in the maritime sector, and we are honoured to have been selected to help the US Navy maintain its competitive edge over the next decade.
“With defence and national security an increasing priority for many governments, I am proud of the role Serco plays in supporting the defence of nations and citizens, for the US Armed Forces and for other governments and militaries around the world.”
The contract award continues the recent strong momentum Serco has seen in defence, with the sector comprising over 80 per cent of its order intake in the first half of 2025.
