58 -- AIR SURVEILLANCE AND PRECISION APPROACH RADAR CONTROL SYSTEM POC Karen Perkins, (301)757-5928 or Robert Wolfe, Contracting Officer, (301)757-5916 17. This synopsis is a follow-on to the Request for Information requesting industry comments on the Air Surveillance and Precision Approach Radar Control System (ASPARCS) for use by the Marine Corps (SOL 50016-98 posted March 3, 1998). THIS IS NOT A SOLICITATION, BUT A REQUEST FOR INFORMATION. THE GOVERNMENT WILL NOT PAY FOR THE INFORMATION SUBMITTED IN RESPONSE TO THIS SYNOPSIS. The Naval Air Systems Command, Air Traffic Control and Landing Systems (PMA213) intends to procure 15 mobile ASPARCS for use by the Marine Air Traffic Control Detachments of the Marine Air Control Squadrons. The ASPARCS shall consist of three subsystems: the Air Surveillance Radar (ASR), the Precision Approach Radar (PAR), and the Operations (Ops) Subsystem. Each of the three subsystems shall be transportable on a variant of the High Mobility, Multi-Wheeled Vehicle (HMMWV), and the ASR and PAR shall be capable of operating from a variant of HMMWV. In addition, each system shall be removable from the HMMWV and operable while separated from the HMMWV. Standard variants of the HMMWV trailer may be used for transportation and operation. Each subsystem shall be transportable by C-130, heavy lift helicopter (external), rail, sea, and flatbed truck. The ASR shall provide radar coverage from 0.5 nautical miles (nmi) to 45 nmi, with altitude coverage from 100 feet to 40,000 feet. The ASR shall include secondary surveillance radar (SSR), Identification Friend or Foe (IFF) coverage out to 60 nmi and from 100 feet to 40,000 feet in altitude. The IFF shall have MARK X/XII, Modes 1, 2, 3/A, C, 4, and Mode S capability. The PAR shall provide a Category I approach capability from a maximum range of 10 nmi to a minimum of 200 feet above runway threshold and 0.5 nmi from the touchdown zone elevation. The PAR shall be capable of tracking a minimum of four aircraft on final approach with azimuth coverage of +/- 7.5 degrees from runway centerline, and elevation coverage of -1 degree to +6 degrees at ranges of 700 feet to 10 nmi from the antenna. The operations shelter shall be a rapid assembly shelter capable of providing interior environmental control for a maximum of eight control stations (downscalable to four control stations). Each control station shall be provided a display capable of displaying ASR, PAR, Flight Data, Maintenance, and Training modes. Entries and data input at each station must be shared with all other stations to prevent loss of control in the event of controller station failure. The Air Traffic Control and PAR software for the control stations shall be previously proven to interface with the Federal Aviation Administration (FAA) and provide automatic hand-off/hand-over. The automated interface to the FAA shall be via a government provided landline. A high speed Tactical Data Link (TADIL J) is required and an interface to the Government furnished, AN/ARC-210 based communications system shall be provided by the hardware contractor. Weather sensors and displays shall be provided. Each subsystem shall be provided generator power. A capability to separate both the ASR and the PAR a minimum of 3,000 meters from the Ops subsystem (ASR and PAR are not to be collocated) is required. The capability to operate each of the sensors independently is required. The goal is to procure an Off-The-Shelf/Non-Development Item. Modifications to existing, fielded systems are allowed but should be kept to a minimum. Due to life cycle cost constraints, a system with major components unique to the Marine Corps is not acceptable. The current budget allows for approximately $4M for each of the fifteen systems currently planned. The initial operational capability date for the first article is projected as FY02. Full operational capability is planned for FY06. Approximately $5M for non-recurring engineering is available during the period FY00 and FY01. Interested parties are encouraged to closely review the requirements as set forth in the proposed Operational Requirements Document and provide us your candid comments regarding technical, cost, and schedule plausibility. As previously indicated, this procurement will be heavily reliant on cost as an independent variable. If the current requirements have exceeded cost thresholds, it would be beneficial to all concerned to know this as soon as possible. Specific recommendations, if appropriate, are encouraged. As an alternative to procurement of the entire system from industry, the government is considering providing the operations subsystem (with the rapid deployable shelter, environmental controls, controller stations, displays and processors) and the communications subsystem as GFE. Industry comments regarding this approach are also solicited. A copy of the proposed Operational Requirements Document for ASPARCS is available from Ms. Karen C. Perkins, Contract Specialist, AIR-2.4.2.6.2, at (301) 757-5928, fax (301) 757-5955, or email, perkinskc@navair.navy.mil. Posted 01/19/99 (W-SN289121). (0019)
