1.0 SCOPE

The O&M Contractor shall operate, maintain, and support the Relocatable Over-the-Horizon Radar (ROTHR) system in accordance with this performance work statement, 24 hours/day, 7 days/week, 365/366 days/year. The ROTHR system consist of, at a minimum, the Operations Control Center (OCC) system which includes OCC, manned and unmanned ADP and Communications Center; transmit and receive systems, subsystems, shelters; support facilities, facilities systems and subsystems; system trainer/test bed; air conditioning, mechanical, electrical, fire suppression systems and subsystems; test equipment; and new system configurations upon installation. This effort includes providing support for systems engineering; engineering change proposal analysis; failure analysis; configuration management; installation and/or testing of field change kits; logistics support including but not limited to spares replenishment and test and support equipment; training; repair/refurbishment services; reverse engineering, and supporting next generation Over-the-Horizon Radar (OTHR) test systems/prototypes and operational systems.

This requirement presents several challenges to the O&M Contractor including having to work with a mature system, dealing with parts obsolescence, implementing actions to operate and maintain ROTHR more efficiently, and coordinating with the Original Equipment Manufacturer contractor for the system who owns the Level 3 documentation for the radar systems. Detailed technical characteristics, description, and requirements for the ROTHR system are defined in the latest revision of specification ELEX-R-570 REV B, Users Logistics Support Summary (ULSS), Level 1 and 2 documentation, and ROTHR Technical Manuals and COTS manuals located in the Master Technical Library (see PWS Paragraph 9.1).

Overarching Operating Constraints: The Contractor shall ensure that all radar sites are fully staffed during adverse weather conditions or other conditions affecting travel to or from the radar sites. In these situations the contractor’s on site workforce may be required to remain at the radar site for periods up to 36 hours duration until conditions allow a change of personnel however, the typical duration is less than 24 hours. The only exception are extreme conditions that present a potential threat to the health and/or safety of personnel at the radar site in which case FSSC will make a determination to shut down radar operations until the condition is mitigated. Severe storms such as a hurricane may cause a radar site to shut down and send personnel home. The Contractor shall be knowledgeable of historical weather conditions for all geographical areas where the radar sites are located.

- Virginia sites - seasonal snow, ice, storms, flooding, and hurricanes can affect travel to/from these sites.

- Texas sites - seasonal storms and flooding can impact travel to/from these sites. Also, there is approximately a twelve-mile unimproved road leading to the radar receiver site located at Freer, Texas. This road is constructed of Caliche (a calcium carbonate mineral) material and is typically rutted and uneven. Four wheel drive vehicles are typically used to travel this road especially during periods of rain and/or minor flooding. The road becomes impassable during periods of heavy flooding, typically lasting less than 24 hours.

- Puerto Rico Sites - seasonal storms, flooding, lightning, and hurricanes can affect travel to/from these sites. Adverse weather conditions or other interruptions can affect commercial air and marine carriers to/from the radar transmitter site at Vieques.

2.0 MISSION & BACKGROUND

The mission of Forces Surveillance Support Center (FSSC) is to provide tactically significant air and maritime track data to JIATF-S, resulting in multiple JIATF-S products that counter illicit trafficking posing a threat to National Security. The ROTHR system supports the National Drug Control strategy with detection and monitoring of the Source Zone through the Transit Zone 24 hours a day, 7 days a week. ROTHR is tactically controlled by the Joint Interagency Task Force South (JIATF-S) in Key West, FL.

ROTHR was developed in the mid-1980s during the Cold War to combat the Backfire bomber threat to the US Navy. Fleet Surveillance Support Command (FSSC) was established in 1987 to operate and maintain 13 systems worldwide to provide over-the-horizon surveillance for the carrier battle groups. As the Cold War was ending, a limited production buy of three systems occurred in 1989 with intentions to mothball the systems after acceptance testing. A prototype ROTHR system underwent Operational Evaluation (OPEVAL) in 1989 then deployed to Amchitka, Alaska from 1991 to 1993. The mission changed to detection and monitoring to support counterdrug operations in 1993. Except for military personnel funding, all Navy operational funding ceased in 1994 and was replaced by DoD fenced counterdrug funding. ROTHR-VA was declared Full Operational Capability in June 1993. ROTHR-TX was declared Full Operational Capability in June 1995. ROTHR-PR was declared Full Operational Capability in June 2000. Fleet Surveillance Support Command transitioned to Forces Surveillance Support Center (FSSC) with civilian personnel when all military personnel were returned to the fleet in September 2004.

ROTHR consists of the Operations Control Center (OCC) system, three land-based, bi-static, high frequency, Doppler radar systems consisting of transmitter and receiver sites, and support facilities. The three ROTHR systems are located in Virginia, Texas, and Puerto Rico. ROTHR Virginia Receiver Site consists of the Operations Control Center (OCC) system in Bldg. 344, support facilities in Bldg. 310 and Bldg. 344, storage facility in Bldg. 363, and antenna maintenance facility in Bldg. 446 located at Naval Support Activity Hampton Roads, Northwest Annex, Ballahack Road, Chesapeake, Virginia. The ROTHR Virginia Transmitter Site, consists of a support building (NK-1), government support building (NK-2), grounds maintenance building (NK-3), and storage Bldg. 4 (NK-4), and is located in New Kent County, Virginia. ROTHR Texas transmitter site consists of a support building (TX-1), grounds maintenance building (TX-2), and electronics maintenance building (TX-3), is located approximately one mile south of the intersection of routes US 281 and TX 141 approximately 20 miles west of Kingsville, Texas. The ROTHR Texas transmitter site is expanding to include a transmitter support building and antenna field associated with the Maritime Centric Skywave Over-the-Horizon Radar (MASOR). The ROTHR Texas Receiver Site consist of a support building (TR-1) and a grounds maintenance building (TR-2), and is located approximately 13 miles on County Road 401 off route TX 44 near the intersection of routes TX 16 and TX 44 in Freer, Texas. ROTHR Puerto Rico Transmitter Site, consist of a support building (PX-1), grounds maintenance facility (PX-2), and equipment storage shed (PX-3), and is located on the southwest end of the Island of Vieques, Puerto Rico. The ROTHR Puerto Rico Receiver Site consists of a support building (PR-1), and grounds maintenance facility (PR-2), and is located at Fort Allen in Juana Diaz, Puerto Rico approximately 16 miles from Ponce, Puerto Rico. The Government will provide physical security services to protect the radar at both Puerto Rico sites.
