(RRH) within the United Kingdom Air Surveillance and Control System (UKASACS). The radar at Staxton Wold is a Lockheed Martin AN/TPS-77 radar which was due to be working by September 2013, but only became fully operational in early 2015. In September 2017, it was reported that the TPS-77 at Staxton Wold would be transferred to RRH Saxa Vord. As part of a major upgrade of RRH sites around the U.K. the MOD began a programme titled HYDRA in 2020 to install new state-of-the-art communications buildings, radar towers and bespoke perimeter security.
