CUVX Design – VT Team 2 Page 273.2.6 Combat System Alternatives3.2.6.1 Combat System RequirementsCUVX shipboard combat systems are primarily for self-defense. CUVX offensive capabilities are provided byits airwing.3.2.6.2 AAWAAW systems on CUVX are integrated by the Ship Self Defense System (SSDS). This system is intended forinstallation on all non-Aegis ships. The SSDS improves effectiveness by coordinating hard kill and soft kill andemploying them to their optimum tactical advantage. However, SSDS does not improve the performance of anysensor or weapon beyond its stand-alone capability. The SSDS is a versatile system that can be used as a tacticaldecision aid or an automatic weapon system.SSDS uses mostly Commercial Off-the-Shelf (COTS) products, including a fiber optic Local Area Network(LAN). SSDS employs single or multiple Local Access Unit (LAU) cabinets with an Uninterruptible PowerSupply (UPS) and VME card cage. Processor cards are identical and interchangeable, so spares can be stocked.CUVX AAW trade-off alternatives include goal and threshold systems listed in Table 18. The alternatives areidentical except for the missile systems. Both include: AN/SPS-49A(V)1, Very Long-Range Air SurveillanceRadar; AN/SPS-73(V)12, Surface Search Radar; AN/SLQ 32A(V)2, Electronic Warfare System; CentralizedIdentification Friend or Foe (CIFF); Phalanx Close-In Weapons System (CIWS); Mk36 Decoy Launching System(DLS); Combat Direction Finding (DF); and Infrared Search and Track (IRST). The AAW goal missile system isan Enhanced Sea Sparrow Missile (ESSM) 2x4 cell Peripheral Vertical Launching System (VLS). This issupported by the Mk91 Guided Missile Fire Control System (GMFCS) w/Mk93 Target Acquisition System (TAS)and AN/SPQ-9B Radar. The AAW threshold missile system is the Rolling Airframe Missile (RAM). All sensorsand weapons in each suite are integrated using SSDS. Specific sub-system descriptions are as follows:• AN/SPS-49A(V)1 Very Long-Range Air Surveillance Radar is a long-range, two-dimensional, air-searchradar system. It provides automatic detection and reporting of targets within its surveillance volume. Itoperates in the presence of clutter, chaff, and electronic counter-measures. It has a line of sight / horizonstabilized antenna for low altitude targets and an upshot feature for high-diving threats.• AN/SPS-73(V)12 Radar is a short-range, two-dimensional, surface-search/navigation radar system. Itprovides contact range and bearing information. It also enables quick and accurate determination ofownship position relative to nearby vessels and navigational hazards, making it valuable for navigationand defense.• AN/SLQ-32 Electronic Warfare (EW) System provides warning, identification, and direction-finding ofincoming anti-ship cruise missiles (ASCM). It provides early warning, identification, and directionfindingagainst targeting radars. It also provides jamming capability against targeting radars.• CIFF (Centralized Id. Friend or Foe) is a centralized, controller processor-based system that associatesdifferent sources of target information. It accepts, processes, correlates and combines IFF sensor inputsinto one IFF track picture. It controls the interrogations of each IFF system and ultimately identifies alltargets as a friend or foe.• DLS (Decoy Launching System) defends against ASCMs which have penetrated to the terminal-defensearea. It can launch an array of chaff cartridges against a variety of threats by projecting decoys aloft atspecific heights and ranges. It confuses hostile missile guidance by creating false signals.• Combat DF (Direction Finding) is an automated long range hostile target signal acquisition and directionfinding system. It can detect, locate, categorize and archive data into the ship’s tactical data system. Itprovides greater flexibility against a wider range of threat signals. Combat DF also provides warshipcommanders near-real-time indications and warning, situational awareness, and cueing information fortargeting systems to make timely decisions.• MK91 GMFCS (Guided Missile Fire Control System) provides an additional layer of ship missile defense.It combines the Firing Officer Console and Radar Set Console functionality into a single AdvancedDisplay System Console. It detects, tracks, identifies, evaluates, and assigns weapons for use againsthigh-speed, small cross-section targets.
