The AN/SPS-67 is a short-range, two-dimensional, surface-search/navigation radar system that provides highly accurate surface and limited low-flyer detection and tracking capabilities.
The AN/SPS-67 is a solid-state replacement for the AN/SPS-10 radar, using a more reliable antenna and incorporating standard electronic module technology for simpler repair and maintenance. The AN/SPS-67 provides excellent performance in rain and sea clutter, and is useful in harbor navigation, since the AN/SPS-67 is capable of detecting buoys and small obstructions without difficulty.
The AN/SPS-67(V)1 radar is a two-dimensional (azimuth and range) pulsed radar set primarily designed for surface operations with a secondary capability of anti-ship-missile and low flier detection. The radar set operates in the 5450 to 5825 MHz range, using a coaxial magnetron as the transmitter output tube. The transmitter/receiver is capable of operation in several pulse width settings: a long (1.0 µs), medium (0.25 µs), or short (0.10 µs) pulse mode to enhance radar performance for specific operational or tactical situations. Pulse repetition frequencies (PRF) of 750,1200, and 2400 pulses/second are used for the long, medium, and short pulse modes, respectively. The higher PRF settings coupled with the shortest pulse increases the resolution of the return and enables the radar operator/observer to discern or differentiate between a single large target or 2 smaller targets in close proximity to each other.
The AN/SPS-67(V) is a search and surveillance radar is designed primarily for use on surface vessels. The radar performs the functions of navigation, station keeping, and general surface search functions. The AN/SPS-67(V)3 and (V)5 variants additionally provide a quick reaction automated target detection and track capability to the MK 34 Gun Weapon System (GWS) in surface engagements, low elevation air engagements and Naval Gunfire Support aboard the DDG-class ships.
AN/SPS-67(V)1 was installed in the 1980s on BB, FF, LCC, LHD, LHA, LSD, LPD, CV and CVN-class ships. The AN/SPS-67(V)3 was installed beginning in the 1990s on DDG 51-102. It was implemented to provide track data to the GWS via AEGIS Command and Decision (C&D). AN/SPS-67(V)5 installations began in the 4th quarter of FY07 aboard DDG 72-102 under SCD 72067 as a backfit and DDG 103-118 as production units to mitigate obsolescence issues with the AN/SPS-67(V)3 Signal Processor. The AN/SPS-67(V)5 is a Commercial-Off-The-Shelf (COTS) Refresh for AN/SPS-67(V)3 Radar, which eliminated all the Standard Electronic Modules. Synthesizer Expander Modules, and replaced the Signal Processor Unit with new Versa Module Eurocard (VME)-based COTS processors, and still maintained the existing (V)3 requirements and interfaces.
The AN/SPS-67(V)5 has been tested and qualified to Shock MIL-STD-901D, Vibration MIL-STD-167 and Electromagnetic Interference certification MIL-STD-461D and E.
The AN/SPS-67(V)5 radar is maintained by the Electronics Technician rating under Navy Enlisted Classification 9615. Tactical operation and monitoring of the radar’s AEGIS C&D interface is performed by an Operations Specialist from the ship’s Combat Information Center (CIC) console in the Surface Detector Tracker sub-mode, as a collateral duty. There are no watch station requirements for this system.
AN/SPS-67(V)5 maintenance training is provided in an instructor-guided classroom format using Computer Aided Instruction modules to train and learn equipment operation, testing, fault identification and system troubleshooting. Part-Task Trainers are used to train students in transmitter modulator driver assembly maintenance tasks. Students also use the radar’s Interactive Electronic Technical Manual in the classroom.
The maintenance technician is required to troubleshoot, fault isolate and replace Lowest Replaceable Unit (LRU)-level and, in some instances, even isolate and repair faults at the component level. The Source Maintenance and Recoverability codes in the system’s provisioning documentation identify the repair level for each maintenance significant item. Troubleshooting and fault isolation of COTS parts is primarily accomplished by system Built-In-Test (BIT) function. BIT identifies and isolates 95 percent of detected faults to a single LRU in the parts it monitors within the Receiver Processor (RP), and up to a maximum of four LRUs within the Receiver/Transmitter (R/T), Power Distribution Unit (PDU) and Antenna Control Unit (ACU). BIT measures output power, noise figure and Voltage Standing Wave Ratio (VSWR) while the radar is operating without degrading the radar performance.
The current AN/SPS-67(V)5 radar is a two-dimensional (azimuth and range) pulsed radar set primarily designed for surface operations with a secondary capability of anti-ship-missile and low flier detection. The radar set operates in the 5450 to 5825 MHz range, using a coaxial magnetron as the transmitter output tube. The R/T is capable of operation in a long (1.0 usec), medium (0.25 usec) or short (0.10 usec) pulse mode to enhance radar performance for specific operational or tactical situations. Pulse Repetition Frequencies of 750, 1200 and 2400 pulses per second are used for the long, medium and short pulse modes, respectively. The antenna can be rotated at two different speeds (15 and 30 Revolutions Per Minute) and the system includes an automatic tracker. The system also operates as the backup Identification Friend or Foe (IFF) antenna.
The AN/SPS-67(V)5 radar set includes seven (7) major functional elements: Radar Set Control (RSC), Receiver/Transmitter (R/T), Power Distribution Unit (PDU), Antenna Control Unit (ACU), Antenna Safety Switch, Antenna, and Radar Processor Unit (RPU). The radar is used on Flight II and IIA DDGs. All below deck hardware is located in Radar Room #2, which is in a cipher locked room, with the exception of the RSC which is located in CIC, also a cipher locked area.
The RP processes 60 MHz Intermediate Frequency from the R/T and provides display video and track data output as directed by the operator via the C&D system. The RP provides automatic target detection, centroiding and tracking of targets. It provides track and contact data to C&D for GWS use. The RP also features comprehensive BIT functionality and an Electronic Fault Isolation Tool that allows fault detection and localization down to the LRU-level. The unit is a bulkhead mounted cabinet containing a control panel, multi-voltage power supply, power conditioning and distribution subassemblies and a VME card rack subassembly.
The RP Control Panel (RPCP) provides radar and BIT controls using a Thin Client that provides a menu driven windowed display interface. Operator inputs are made using a touch-sensitive overlay on the display screen. The RPCP communicates with the Tracker Processor, Centroid Processor and RSC via the internal Local Area Network. The RSC provides the operator controls using a windowed Graphical User Interface (GUI) with a touch screen. Radar operating modes are selected using the touch screen and the associated display menus. Radar status is displayed on the RSC.
The AN/SPS-67(V)3 and (V)5 radars are compatible with and meet the interface requirements of the AN/SLA-10, IFF equipment, Radar Display and Distribution System, Data Multiplex System (WS-21333), and AEGIS C&D (WS-21343).
In 1983 Northrop Grumman Norden Systems commenced production of the AN/SPS-67 radars, producing a total of 126 AN/SPS-67(V)1 radars and 36 AN/SPS-67(V)3 radars. In 1997, procurement of the AN/SPS-67(V)3 Radar was split into two solicitations, one for below deck equipment and one for the above deck antenna group. Both contracts were competitively awarded and the resulting two procurements included fulfillment of all system requirements through FY2001. In the split procurement, the below decks equipment contract, for 26 units, was awarded to DRS Electronic Systems while the Antenna Group contract, for 26 units, was awarded to Electro-Mechanical Systems.
In FY2003, two follow-on contracts were awarded in support of additional radar system procurements. A Sole-Source contract was awarded to DRS Surveillance Support Systems, Inc. for 12 AN/SPS-67(V)3 below deck units and procurement of 26 AN/SPS-67(V)5 COTS Refresh Kits. The Antenna Group contract was recompeted and awarded to EDO Corporation for 17 antenna units. Congressional Plus-Ups supplemented the program procurement budget through FY04-FY08, bringing the total number of Refresh Kits up to 40.
The AN/SPS-67(V) program is currently being supported by the DDG-51 Restart effort (DDG 113-118). The Program Office has delivered the last two AN/SPS-67(V)5 systems, finishing production with DDG 117 and DDG 118. The SPS-67(V)5 is being replaced by the AN/SPQ-9B on DDG 119 and following. The AN/SPS-67(V)5 is currently installed on DDG 51 Flight II and IIA-class ships and interfaced with existing shipboard systems. DDG 51 Flight I ships require this upgrade to alleviate obsolescence and to gain the enhanced benefits of the AN/SPS-76 67 (V)5 modernized detection and tracking processing supporting Surface GWS engagements in a littoral environment. An engineering Design Agent contract associated with the continued engineering, maintenance, system enhancements and mitigating obsolescence is currently in place to support AN/SPS-67(V) system life cycle sustainment.
