CLOSE-IN WEAPONS SUBSYSTEM

CLOSE-IN WEAPONS SUBSYSTEM The Close-In Weapons Subsystem (CIWS), Mk 15 Mod 1, provides the final defense against antiship cruise missiles (ASCMs) as part of the Navy’s defense-in-depth concept. This subsystem engages and destroys ASCMs or aircraft that penetrate a ship’s primary defense envelope. It also provides ASCM and antiair defense for ships operating in other than defense-in-depth situations and may be operated in either the antiair warfare (AAW) auto- matic or manual mode. The CIWS is essentially a stand-alone weapons system consisting of (1) the Weapon Group, Mk 16 Mod 1; (2) the Remote Control Panel, Mk 340 Mod 1; and (3) the Local Control Panel, Mk 339 Mod 2. UNDERWATER WEAPONS SUBSYSTEM The underwater weapons subsystem provides the combat systems with an engagement capability against subsurface threats. The underwater weapons subsystem is composed of (1) the Sonar Set, AN/SQS-56; (2) the tactical towed array sonar (TACTAS); (3) the Torpedo Tubes, Mk 32 Mod 5; and (4) the Control Panel, Mk 309 Mod 0. LIGHT AIRBORNE MULTIPURPOSE SUBSYSTEM The light airborne multipurpose system (LAMPS) is a computer-integrated, ship-helicopter subsystem that is capable of supporting both combat and noncombat missions. The primary combat mis- sions are ASW and antiship surveillance and targe- ting (ASST). The secondary noncombat missions include search and rescue, medical evacuation, verti- cal replenishment, and utility operations. The LAMPS consists primarily of the SH-60B Seahawk helicopter. This helicopter is an all- weather, airborne platform capable of carrying var- ious detection devices, including a sonobuoy re- ceiver-transmitter for transferring sonobuoy data to the ship. Shipboard LAMPS equipment consists of (1) the Telemetric Data Receiving Set, AN/SKR-4A; and (2) the Sonar Signal Processing Set, AN/SSQ-28. MISSILE/GUN WEAPONS SUBSYSTEM The missile/gun weapons subsystem enables the combat systems to deliver to a target an SM-1 missile warhead or a 76-mm gun projectile. This subsystem uses internally and externally generated raw data and processed data to provide the combat systems with weapons assignment, direction, and firing capability. This subsystem supports the combat system AAW, antisurface warfare (ASUW), and ASW missions. HARPOON MISSILE WEAPONS SUBSYSTEM The Harpoon missile weapons subsystem pro- vides a self-contained, surface-to-surface missile system capable of launching the Harpoon missile at over-the-horizon surface targets. The Harpoon mis- sile weapons subsystem is the ship’s primary surface- to-surface weapon. This subsystem relies on the weapons control processor (WCP) computer and other elements of the combat systems for target detection, threat evaluation, weapon pairing, and target data functions. SUPPORT SUBSYSTEM The support subsystem is absolutely necessary to equipment operation. It consists of the following sub- systems and equipments: 1. Dry air and nitrogen. 2. Liquid cooling and heating. 3. Ship power and distribution. 4-5
