Serco, the international provider of critical services to governments, 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, with a ceiling value of $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.
Serco 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.
