AN/SYQ-17 Rapid Anti-Ship Cruise Missile Integrated Defense System (RAIDS)

The AN/SYQ-17 Rapid Anti-Ship Cruise Missile Integrated Defense System (RAIDS) ) is a tactical decision aid forthe Commanding Officer/Tactical Action Officer and the Electronic Warfare Supervisor. It provides automatic display of anti-ship cruise missile (ASCM) threats, depicts active and passive sensor displays, and shows the status of existing terminal self-defense systems. RAIDS, a multiple microprocessor-based system, considers threat capabilities, environmental data, electromagnetic interference data, ownship maneuvering parameters, and approved tactical doctrine to develop a dynamic tactical deision matrix that provides a ship's anti-ship missile defense (ASMD) coordinators with concise and real-time tactical engagement recommendations. These recommendations are continually and automatically evaluated for effectiveness and updated as appropriate. RAIDS also provides realistic and accessible closed-loop simulation training.

RAIDS' distributed architecture facilitates software upgrades as well as combat sensor and weapon upgrades and additions. In the near term, communications between RAIDS data processors in the Data Processing Center (DPC) and the Close-In Weapon System (CIWS) Remote Interface Units (RIUs) will be via a fiber optic Local Area Network (LAN). The AN/SYQ-17 RAIDS has become a prominent component of the Combat System aboard OLIVER HAZARD PERRY (FFG-7)-class frigates and SPRUANCE (DD-963)-class destroyers. The 5.6 version of RAIDS takes on the EW Sub-mode functionality that formerly resided within the Combat Direction System (CDS). In becoming comfortable with this relocation of functionality, many ships have struggled with the transition of ES tracks passing through RAIDS into CDS. There is a notable diversity to ES track reporting through RAIDS. CDS has the capability to change track ID and symbology without operator intervention. Fleet feedback indicates this capability is not adequately understood, and the change in ID is believed to be caused by RAIDS.

If a designated emitter is among the top six threats held by RAIDS, the emitter will become a RAIDS tactical candidate. It will be sent to CDS because all RAIDS tactical candidates are sent to CDS. Then all data changes for the emitter received from AN/SLQ-32(V) will be passed to CDS. Some interesting events may arise during this reporting process. Specifically, an emitter can be sent to CDS (thus obtaining a system track number) and later dropped from RAIDS displays without operator intervention. With CDS RE-ID set to NONE and Evaluations set to MANUAL, RAIDS changed “Air Unknown” in CDS to “Air Unknown Assumed Enemy” with an IDAMP of missile platform if SLQ-32 held a missile platform emitter on the same bearing as an air platform that was heading directly towards ownship.

The RAIDS TAO Doctrine controls for track management include doctrine controls on re-identification of CDS tracks, AN/ SLQ-32(V) tracks and RAIDS track associations. These may be configured such that the AN/SLQ-32(V) emitter will be allowed to associate with a radar track. This association refers to the condition when the kinematic data for the vehicular track exhibits characteristics that resemble those held by the platform that carries the detected emitter. When this happens, the emitter stays in CDS along with the radar track even while it has been combined as a single composite track within RAIDS. Hence, there is no separate symbol displayed on RAIDS for the emitter until the association breaks. At that time, there is a change in RAIDS to match CDS. Noting that the displays are different, the operator typically monitor the track according to your situational assessment. If the operator agrees with the association and believes there is really only one track out there; they use RAIDS to monitor the track.

Certain ES tracks are sent to CDS regardless of AN/SLQ-32(V) operator actions and tactical candidates. Emitters that match the ES Mode Control settings are sent to CDS. ES Mode Control is set within the RAIDS EW Supervisor display. It allows the EW Supervisor to pre-set which emitters get automatically reported to CDS according to "Threat Level." So, emitters whose threat level matches the mode control settings are received in CDS automatically. Also, RAIDS-generated manual fixes and manual bearings are sent to CDS when they are entered.

RAIDS has been installed on more than 20 SPRUANCE (DD-963)-class destroyers and is slated to be installed on more than ten OLIVER HAZARD PERRY (FFG-7)-class guided missile frigates.
