DESCRIPCIÓN:
SSM Harpoon:
The Harpoon missile was developed in the early 1970s. Numerous upgrades have kept it at the forefront of missile capabilities, including the Block 1 introduced in 1978, and the Block 1B introduced in 1981. Today, the latest variant developed in 1982 called Block 1C is deployed by the United States military (Navy and Air Force) as well as US allies.
The Harpoon Block II is an upgrade program to improve the baseline capabilities to attack targets in congested littoral environments. The upgrade is based on the current Harpoon. Harpoon Block II will provide accurate long-range guidance for coastal, littoral and blue water ship targets by incorporating the low cost integrated Global Positioning System/Inertial Navigation System (GPS/INS) from the Joint Direct Attack Munitions (JDAM) program currently under development by Boeing. GPS antennae and software from Boeing's Standoff Land Attack Missile (SLAM) and SLAM Expanded Response (SLAM ER) will be integrated into the guidance section. The improved littoral capabilities will enable Harpoon Block II to impact a designated GPS target point. The existing 500 pound blast warhead will deliver lethal firepower against targets which include coastal anti-surface missile sites and ships in port. For the anti-ship mission, the GPS/INS provides improved missile guidance to the target area. The accurate navigation solution allows target ship discrimination from a nearby land mass using shoreline data provided by the launch platform. These Block II improvements will maintain Harpoon's high hit probability while offering a 90% improvement in the separation distance between the hostile threat and local shorelines. Harpoon Block II will be capable of deployment from all platforms which currently have the Harpoon Missile system by using existing command and launch equipment. A growth path is envisioned for integration with the Vertical Launch System and modern integrated weapon control systems. With initiation of engineering and manufacturing development in 1998, initial operational capability for Block II will be available by 2001.

SAM Misil Standard SM-1MR (Block VI B RIM-66E-6):
The final SM-1MR version was the Block VI, designated RIM-66E (RIM-66C/D versions are SM-2, see below). The RIM-66E featured the monopulse seeker of the SM-2, and a new MK 45 MOD 4 proximity fuze (also known as TDD - Target Detection Device). Production began in 1980, and the RIM-66E entered service in 1983. It is still in production for export customers. The subvariants of Block VI include RIM-66E-1/3/7/8 (-3/8 have the MK 115 warhead of SM-2). Block VI A (RIM-66E-5) and Block VI B (RIM-66E-6) had later MODs (6 and 7, respectively) of the MK 45 fuze for improved performance against low-RCS targets, and both use the MK 115 warhead.

MK 13 MODS 4
We will now study the Standard launching system by covering a launcher commonly known as the “one-armed bandit.” The Mk 13 Mod 4 GMLS is installed aboard FFG-7 Oliver Hazard Perry-class ships and the Mk 13 Mod 7 is installed aboard CGN-36 California- class ships. They provide a varied tactical arsenal of missiles to engage air and surface targets. It stows, selects, identifies, loads, aims, and fires Standard SM-1, SM-2, and Harpoon missiles.
SAM SeaSparrow (RIM-7P), lanzador Mk29
The Navy's RIM-7M Sea Sparrow and the Air Force's AIM-7 Sparrow are radar-guided, air-to-air missiles with high explosive warheads. They have a cylindrical body with four wings at mid-body and four tail fins. The Navy uses the Sea Sparrow version aboard ships as a surface-to-air anti-missile defense. The versatile Sparrow has all-weather, all-altitude operational capability and can attack high-performance aircraft and missiles from any direction. It is widely deployed by U.S. and NATO forces. The Sea Sparrow is found aboard many U.S. and NATO surface warships.
The new RIM-7P software features advanced guidance algorithims that enable Seasparrow to counter the most formidable threats. The missile’s Improved Low Altitude Guidance (LAG) mode makes the RIM-7P exceptionally effective against very low altitude threats, such as sea skimming cruise missiles. In addition, the missile has proven to be highly effective in stressing Electronic Attack (EA) environments.
In 1974 a new launcher was introduced: The Mk 29 Sea Sparrow launcher. It had a lower weight and did not use the RIM-7G but the improved RIM-7H missiles. Today, this launcher is also used by many NATO navies. This system is also known as IPDMS (Improved Point Defense Missile System).

Radar de búsqueda aérea de largo alcance LW08:
Manufacturer: Hollandse Signaalapparaten BV (SIGNAAL)
The JUPITER/LW 08 2D-early warning radar performs long range (260 km on 2 m² RCS target) air surveillance on board medium and heavy-tonnage ships. JUPITER/LW 08 operates in D-band, and is available with a cost-effective fully solid-state transmitter. The antenna is mounted on a lightweight hydraulically stabilised platform (roll and pitch).
The synthesiser-driven travelling wave tube transmitter provides for a great flexibility over a wideband frequency, with pulse-to-pulse frequency agility. Together with the low sidelobe level of the antenna (with cosecant squared pattern) the radar has a high performance in an electronic countermeasures polluted environment. Excellent clutter suppression is the result of
· the applications of antenna stabilisation,
· a receiver with a high dynamic range,
· quadrature digital moving target indication processing,
· and circular polarisation.

Radar Scout LPI
Scout™ Low Probability of Intercept Surveillance System
Manufactured by MSSC (a joint venture of DRS Communications Company, LLC and THALES Naval Nederland), the SCOUT™ radar is a truly Low Probability of Intercept (LPI) radar system designed for shipboard surveillance and navigation applications. While it has detection performance characteristics similar to the AN/BPS-16 or other navigation radars, the SCOUT™ radar uses a Frequency Modulated Continuous Wave (FMCW) transmit waveform that enables it to detect a target well before the target's ESM equipment can detect the SCOUT™.
The SCOUT™ is a Low Probability of Intercept (LPI) radar primarily due to the low peak power -- just 1 Watt -- sent into the antenna. By comparison, a pulsed radar requires around 25 kW peak power into the antenna. Furthermore, the FMCW radar can meet many mission requirements with as little as 1 mW power. Typically the SCOUT™ radar cannot be detected by electronic surveillance equipment or radar warning receivers at ranges greater than a few kilometers. Under the same conditions, a pulsed radar is detectable by these devices at ranges exceeding 50 km
Sonar: Westinghouse AN/SQS-509 de casco
All versions of the SQS-509 have a 360-degree (panoramic) long-range surveillance capability in both passive and active modes. The SQS-509 can track multiple targets while searching for others. It has a 12-ping screen history and a five-ping history on fine video. Target classification takes place using target history, hydrophone effects, Doppler, aspect and audio techniques. Operation is by quick entry button and symbology. Single-operator control is augmented by facilities for computer-aided tracking.
Full interface with the ship's Action Information Center (AIO) allows multiple repeater display in the Combat Information Center (Operations Room). (See UYS-501 report.) Built-In Test Equipment (BITE) facilities are included.
The SQS-509's transmitter group consists of a power supply and a transmitter. The power supply unit converts the ship's housekeeping AC supply into DC. The power supply unit is housed in a standard SQS-509 cabinet. The transmitter consists of 36 power output modules, each driving one stave of the transducer array. The solid-state receiver group is contained in three standard cabinets. Automatic Test Equipment allow fault tracing down to modular level. Future fittings and upgrades to the SQS-505 will almost certainly involve the fitting of SHINPADS (see UYQ-501(V) report) for operation and display of data acquired through the use of sonar.
The SQS-509's transducer array is about 1.2 m in diameter and 1.2 m deep. Each array contains 360 discrete elements arranged in 36 staves with 10 elements per stave.

Sistema de defensa de punto (Close-In Weapon), cañón Goalkeeper
Goalkeeper is a Dutch close-in weapon system, the purpose of which is to defend a ship against incoming missiles and ballistic shells. The system consists of an autocannon and an advanced radar which tracks incoming fire, determines its trajectory, then aims the gun and fires in a matter of seconds. The system is fully automatic, needing no human input once activated. The kinetic energy of the 30mm rounds is sufficient to destroy any missile or shell. The system can also be deployed to protect airfields. The name comes from the football (soccer) position.

Dos lanzadores dobles fijos Mk32 mod 9, para torpedos Mk46 mod 5
The MK-46 torpedo is designed to attack high performance submarines, and is presently identified as the NATO standard. The MK-46 torpedo is designed to be launched from surface combatant torpedo tubes, ASROC missiles and fixed and rotary wing aircraft. In 1989, a major upgrade program began to enhance the performance of the MK-46 Mod 5 in shallow water. Weapons incorporating these improvements are identified as Mod 5A and Mod 5A(S). The MK-46 Mod 5 torpedo is the backbone of the Navy's lightweight ASW torpedo inventory and is expected to remain in service until the year 2015. The MK 46 originated with the RETORC I (Research Torpedo Configuration I) program conducted by the US Naval Undersea Center (NUC) at Pasadena, CA.
