Remote Mine-hunting System

Illustration of an Remote Mine-hunting System conducting operations

Description: The Remote Mine-hunting System is a high-endurance, remotely operated, surface ship-launched and —recovered, semi-submersible vehicle towing a mine-reconnaissance sonar. The RMS will conduct reconnaissance of bottom and moored contact mines from the deepwater-region to the 30-foot contour. Mine reconnaissance operations conducted by the RMS will determine the presence of mine-like objects and safe routes through or safe operating areas around potential minefields.

Program Status: In Fiscal Year 1997, the RMS concept was successfully demonstrated by employment of a prototype system from the USS Cushing (DD-985) during an Arabian Gulf exercise. The EMD phase for RMS will complete in FY 2005. The operational system will be installed in the Arleigh Burke (DDG-51) Flight IIA Aegis guided missile destroyers beginning with DDG-91.

Advanced Cryptologic Carry-on
Exploitation System

Description: ACCES is a carry-on cryptologic exploitation capability for ships not equipped with a permanent cryptologic capability. ACCES hardware and software are similar to that of the SSEE (AN/SLR-25(V)2) system, with minor hardware differences to facilitate multiple shipboard installations and removals. The system provides front-end sensor (receiver) control through Local Monitor Station (LMS), tactical surveillance, targeting, and Indications and Warning (IW), as well as passive detection, classification, and tracking of selected targets at extended range. It also provides tools to allow interpretation and reporting of intercepted data, geographic plot and analysis, and track correlation. When ACCES is paired with a ransportable-Radio Direction Finding (T-RDF) system, the supported warship commander has a comprehensive and complete signals intelligence (SIGINT) capability.

Program Status: Installations in Arleigh Burke (DDG-51) Aegis destroyers and amphibious assault ships continue.

Ship's Signal Exploitation Equipment

Description: AN/SLR-25(V)2 SSEE Phase 2 program is a signal acquisition system that provides warship commanders with threat identification information. SSEE also provides cueing to radio direction finding assets. When SSEE is paired with a Transportable-Radio Direction Finding (T-RDF) system, the supported warship commander has a comprehensive and complete signals intelligence (SIGINT) capability. SSEE is a COTS/NDI program that is easily reconfigured and therefore able to respond rapidly to tasking. The system design permits the rapid insertion of new and emerging technologies and is the building block that will integrate capabilities from existing systems and insert advanced technologies into a single, scalable, interoperable Maritime Cryptologic System for the 21st Century (MCS-21). SSEE Increment E will be the first step towards MCS-21 and will improve front-end sensor capabilities (software receivers) to exploit current and emergent signals of interest, integrate RDF and enable Information Warfare capabilities, and provide embedded scenario based training.

Program Status: SSEE Phase 1 is installed on one command ship, the USS Mount Whitney (LCC-20) and three amphibious assault ships (LHA). SSEE Increment B is fielded on 14 Ticonderoga (CG-47) Aegis cruisers, 13 Spruance (DD-963) destroyers, the USS Blue Ridge (LCC-19), and one Wasp (LHD-1) amphibious assault ship. SSEE Increment D(2) is fielded on 11 CG-47 cruisers and one amphibious command ship (AGF). Increment D(3) deliveries began in Fiscal Year 2001.

Electronic Warfare System

Description: An integral component and an effective asset in the Navy's Ship Self-Defense System (SSDS, see separate program summary), the AN/SLQ-32A Electronic Warfare System comprises three modular versions with increasing levels of complexity and capability. The SLQ-32A(V)1 provides warning, identification, and direction-finding of incoming anti-ship cruise missile (ASCM) terminal-guidance radars. The (V)2 adds early warning, identification, and direction-finding against the targeting radars associated with these ASCMs. The (V)3 adds a jamming capability against the targeting and ASCM terminal guidance radars. Variations of the SLQ-32A(V)3 systems have been installed on aircraft carriers (V(4)) and Oliver Hazard Perry (FFG-7) -class guided missile frigates (V(5)).

Program Status: More than 200 SLQ-32 systems have been installed on U.S. ships as of FY 2001. The system will eventually be replaced by the Advanced Integrated Electronic Warfare System (AIEWS, see separate program summary), but it is expected to remain in the Fleet through 2020.

Radar Improvement Program

Description: AN/SPQ-9B is an active phased-array rotating radar that significantly improves the ability of ships to detect and track low altitude anti-ship cruise missiles (ASCMs) in a heavy clutter environment. The SPQ-9B is a high resolution track-while-scan, X-band, pulse-Doppler radar which will enable detection and establishment of firm track at ranges which allow the combat system to engage subsonic or supersonic sea-skimming missiles at the outer edge of a ship's engagement envelope. SPQ-9B integrates with SSDS Mk 2 on CVNs and LHDs. The upgrade package improves those ships' ASCM defense capabilities to pace the evolving worldwide threat. The SPQ-9B lightweight antenna configuration which will become the standard installation for all ships is also an integral part of the Cruiser Conversion program, providing an ASCM cue to the AEGIS Combat System and gunfire control for the 5"/62 Mk 45 gun.

Program Status: The heavyweight antenna configuration of the SPQ-9B has been successfully demonstrated on the USS Oldendorf (DD-972). The new lightweight antenna configuration is installed on the USS Nimitz (CVN 68) and is scheduled for installation on Oldendorf (DD-972) in early FY 2002 with Operational Test and Evaluation scheduled for late FY 2002. Milestone III decision is planned for early FY 2003.

SPY-1 Radar
Aegis Multi-function
Phased-Array Radar

Description: The AN/SPY-1 radar system is the primary air and surface radar for the Aegis Combat System installed in the Ticonderoga (CG-47) and Arleigh Burke (DDG-51)-class warships. It is a multi-function, phased-array radar capable of search, automatic detection, transition to track, tracking of air and surface targets, and missile engagement support. The third variant of this radar, AN/SPY-1D(V), known as the Littoral Warfare Radar, will improve the radar's capability against low-altitude, reduced radar cross-section targets in heavy clutter environments, and in the presence of intense electronic countermeasures. The radar has also demonstrated a capability to detect and track theater ballistic missiles.

Program Status: The SPY-1D(V) littoral radar upgrade superseded the SPY-1D in new-construction Flight IIA destroyers beginning in FY 1998. SPY-1D(V) is being installed in DDG-91 and planned for installation in DDGs 92-108.
