Anti Submarine Warfare (ASW) 40 nations possess submarines and the threat of submarine attacks is increasing. Submarine operations range from sophisticated drug smugglers to nation-states. Designed to rapidly detect, track and prosecute small-boat threats. Surface Warfare (SUW) Mine Countermeasures (MCM) Mines are cheap, readily available, and can be easily deployed, ideal for terrorists or nation-states seeking to close shipping lanes, disrupt commerce or deny access to ports.

EADS North America’s multi-mode TRS-3D radar is used to automatically locate and track all types of air and sea targets. It provides reliable track initiation and operation, independent of clutter situation for surface and air targets, at a rate of more than 400 tracks per 360 degrees.

The radar’s antenna is made up of a planar phased array pencil-beam array in 16 or 32 rows of 46 radiators each. Electronic phase shifters are incorporated for scanning in elevation. The antenna includes polarization agile, or linear polarized, radiators.

Due to its incorporation of the latest signal processing technologies, the TRS-3D radar system is well-suited for the detection of low and fast-moving objects, as well as asymmetric threats – even in the most severe environmental conditions.

This lightweight system employs electronic stabilization to neutralize the rolling motion of vessels operating in choppy coastal waters, with specific operational modes to protect against sea-skimming cruise missiles and attack helicopters.

It is especially adept at coastal surveillance and long-range tracking for light combatants, while keeping operator workload to a minimum.

TRS-3D supports a ship’s combat management system with sophisticated data, correlating the primary and secondary radar plots/tracks within its own radar tracker, while its modern suite of electronic counter-countermeasures (ECCM) increases resistance to jamming and interference. It features adaptive thresholds with scan-to-scan processing, including several clutter maps to minimize false alarms.

The radar’s dual-target gunfire support mode allows for the use of medium-caliber guns without an electro-optical or radar tracker, while its rapid update rate enables detection of high-explosive projectile splashes with tailored waveforms. FACT SHEETS TRS 3D air search radar

AN/UPX-29A IFF Lockheed Martin MS2 recently validated the COMBATSS-21 software system that will be aboard the nation’s third Littoral Combat Ship (LCS), Fort Worth. During the two-day engineering evaluation, the U.S. Navy approved requirements for multiple functions, including link communications, identification, tracking and mission tracking support.
The COMBATSS-21 software is derived from Aegis Open Architecture and continues the open systems software currently deployed in the Aegis fleet. Aegis and LCS share 95 percent commonality.

The COMBATSS-21 test was conducted at the Mission Systems Integration Center (MSIC) in Moorestown, N.J., and culminated a series of tests to evaluate the capabilities of the COMBATSS-21 open combat system.

The LCS-3 COMBATSS-21 is designed from Lockheed Martin’s Common Source Library (CSL), which enables technology insertions and software fixes to be used many times across multiple programs. The CSL establishes a common requirements and software library for products and builds each program from that same library.

“Our open architecture models and Common Source Library enable our engineers to maximize common components, saving time and money for our customers,” said Rich Calabrese, Lockheed Martin director of Mission Systems. “Our approach enhances life cycle affordability by reducing costs for integration, test and certification and supports the Navy’s objective combat system architecture. This computer program is the basis for the 10 Freedom Class LCS ships recently awarded to Lockheed Martin and continues Lockheed’s alignment of programs to the Navy’s objective architecture goals.”

Currently, Aegis cruisers and destroyers, LCS and Coast Guard programs utilize the CSL, which brings together open combat system components and common information standards.

The Colt-Pielstick PA6B STC is the latest development of the PA6 engine, intended for ships requiring high-propulsion power combined with a lightweight installation. Available in 12-, 16-, 18-, and 20-cylinder configurations, the PA6B engine is designed specifically for the high demands of naval and commercial markets.

The PA6B engine features Sequential Turbo Charging (STC), which uses two turbochargers in parallel for efficient full-power operation and the use of only one turbocharger for low speed, high-torque operation. The use of one turbocharger maximizes the available energy from the whole engine instead of only half the engine, as is typically done. The extra exhaust energy (double) boosts the turbocharger away from surge conditions and delivers the necessary combustion air to allow engine operation in areas otherwise unattainable. Colt-Pielstick PA6B STC Kamewa S3-Series waterjets The new Kamewa S3 series of stainless steel waterjets builds on experience gained from the successful SII series and offers a significant increase in efficiency and a reduction in size, weight and life-cycle costs.

It also incorporates a host of improvements in a lighter, more compact, yet heavy-duty waterjet design that minimises noise and vibration. Small and light with increased propulsive efficiency Features
Stainless steel construction for maximum wear and corrosion resistance
Reduced transom flange diameter, less entrained water, lower weight
90 per cent + efficiency due to mixed flow pump design
Inlet duct optimised for each vessel
Light and robust and bucket and control system for improved manoeuvring For most applications a unit one size smaller than previously specified will give the same performance, giving a 25 per cent reduction in the total unit weight plus entrained water and a transom flange diameter 12 per cent smaller.

Within a given frame size, each waterjet can be optimised for the installation.

Different nozzle diameters provide the right balance between vessel speed and jet velocity, various impeller blade angles can be chosen to match shaft speed, and many shapes of inlet duct are used to avoid flow separation and cavitation.

A revised bucket system cast in stainless steel optimises the distribution of material, providing a strong but light manoeuvring system. M2HB Heavy Machine Gun U.S. government long-term contract ensures ongoing parts interchange with all M2HB machine guns produced in the United States

Rolling Airframe Missile (RAM) Guided Missile System There are more than 100,000 anti-ship missiles in the world's inventories today, posing a serious threat to all naval vessels. Assured destruction of a large stream raid is the only means to ensure ship survival.

The Rolling Airframe Missile (RAM) Guided Missile Weapon System is the world's most modern ship self-defense weapon and has been specifically designed to provide exceptional protection for ships of all sizes. RAM is currently deployed on more than 165 ships in seven fleets, ranging from 95,000-ton aircraft carriers to 500-ton fast attack craft. Licensed production of the RAM Guided Missile Round Pack (GMRP) is under way in Korea.

RAM is a supersonic, lightweight, quick-reaction, fire-and-forget missile designed to destroy anti-ship missiles. Its autonomous dual-mode passive radio frequency and infrared guidance design, requiring no shipboard support after missile launch, uniquely provide high-firepower capability for engaging multiple threats simultaneously.

The MK 44 GMRP and the MK 49 Guided Missile Launching System, which holds 21 missiles, comprise the MK 31 Guided Missile Weapon System. The system has been designed for flexibility in ships' integration, with no dedicated sensors required. A variety of existing ship sensors can readily provide the target and pointing information required to engage the anti-ship threat.

RAM is an international cooperative program between the United States and Germany. The countries share in the cost of developing and maintaining the system. Development and production work is shared between Raytheon in the U.S. and the German companies LFK, DBD and RAMSYS.

The Rolling Airframe Missile has been fired in more than 300 flight tests to date, resulting in a success rate of 95 percent. This extremely high reliability is the culmination of years of development, testing and design improvements.

The MK 44 is also the missile used in the SeaRAM weapon system, replacing the M601A1 Gatling gun in the Phalanx weapon system with an 11-round launcher. The Phalanx sensor suite serves as the search and track radar designating the threat for the RAM missile to intercept. RAM Block 1/1A

RAM has been continually improved to stay ahead of the ever-evolving threat of anti-ship missiles, helicopters, aircraft and surface craft. RAM Block 1 incorporated a new image-scanning seeker with the added capability of autonomous IR all-the-way guidance, thus countering advanced anti-ship missiles that do not employ on-board radar seekers. Enhanced digital signal processing further provides increased resistance to countermeasures and superior performance in severe IR background conditions. An advanced optical target detection device is incorporated to detect very low sea-skimming threats.

The Block 1A configuration incorporated additional signal processing capabilities to defeat helicopters, aircraft and surface craft. Block 1A is in rate production for the Consortium countries and the other countries procuring RAM.

RAM Block 2

Block 2, the next step in the spiral development of the Rolling Airframe Missile, is a kinematic and RF receiver upgrade. A larger, more powerful rocket motor and advanced control section make the missile three times more maneuverable with twice the effective intercept range. This provides the Block 2 missile with the capability to defeat high-maneuver threats as well as the ability to intercept crossing threats. An enhanced RF receiver allows detection of anti-ship missiles that employ low probability of intercept radars. Some 298 new MH-60R SEAHAWK® helicopters with a mix of sophisticated sensors are assuming the U.S. Navy's primary anti-submarine and anti-surface warfare roles of today's SH-60B and SH-60F aircraft. The MH-60R SEAHAWK helicopter elevates tactical maritime mission capability to a new level by building on six decades of Sikorsky's naval helicopter experience. The MH-60R model is the world's most capable naval helicopter available today designed to operate from frigates, destroyers, cruisers and aircraft carriers. Its state-of-the-art mission systems give it an unmatched capability as an airborne multi-mission naval platform. Additionally, the MH-60R aircraft enables modern navies worldwide to benefit from future decades of military interoperability with the U.S. Navy.
