Tender Details

The NAVSUP Fleet Logistics Center Norfolk Philadelphia Office intends to acquire system sustainment support services for the Digital Receivers (DDRx) for the Relocatable Over-the-Horizon Radar (ROTHR) System in Texas, Virginia, and Puerto Rico. The ROTHR System is a relocatable, land based, High Frequency (HF) Radar, which provides wide area surveillance in support of tactical forces afloat through the early detection and tracking of targets of interest, such as aircraft and ships. The ROTHR system is tasked to provide detection and monitoring of drug smuggling aircraft and ships to support the Office of the Department of Defense Coordinator for Drug Enforcement Policy and support counterdrug operations, providing long range detection of narcotic trafficking ships and aircraft as well as filling gaps in the radar coverage provided by fixed and mobile platforms. The U.S. Navy Forces Surveillance Support Center (FSSC) operates, maintains, and sustains three ROTHR systems in Virginia, Texas and Puerto Rico. The digital receiver system delivers significant technological advantages when compared to traditional analog receivers utilized in HF systems to include larger frequency band of operation, larger channel bandwidths, higher repetition frequencies, longer coherent processing times, ability to process different waveforms and the ability to simultaneously execute air, maritime and other missions concurrently by utilizing different digitized channels for each mission.
The digital receivers were fielded by BAE Australia at the ROTHR Texas location under the DIA issued contract HHM402-15-C-0059. This contract is now complete as final delivery was made in November of 2024. The Government currently has a contract with BAE Australia Limited, N00189-22-C-Z021, for additional receivers for the Puerto Rico and Virginia ROTHR locations, which was awarded on a sole source basis in September of 2022. This contract is ongoing as the final delivery under contract N00189-22-C-Z02...
