Royal Thai Navy’s DW-3000F Frigate

ATLAS ELEKTRONIK to deliver Bow and Towed Sonar systems for new Royal Thai Navy frigate

Posted on December 20, 2013

ATLAS ELEKTRONIK GmbH has been commissioned by the Korean yard Daewoo Shipbuilding & Ma- rine Engineering (DSME) with the supply and integration of a bow sonar (ASO) as well as a low- frequency active towed array sonar (ACTAS) for a new frigate of the Royal Thai Navy.

Delivery of the systems is planned to take place early in 2016.

Together, the two systems offer active and passive sonars for the detection, tracking and classification of underwater vehicles, such as submarines, torpedoes and unmanned underwater vehicles (UUV). In addition, these sonars are able to detect and classify small speedboats, divers or floating obstacles, e.g. containers or tethered mines.

The ASO bow sonar operates in the frequency range between 6 and 9 kHz and provides a surveillance radius of up to 15 kilometres around the ship. This makes it most suitable for the self-protection of the ship. The towed array sonar ACTAS operates in the low-frequency range from about 2 kHz and permits observation of the sea space at ranges considerably above 60 kilometres, depending on the propagation conditions of the water. This gives the sonar an operational range that by far exceeds that of radars and the weapons range of submarines. The system is therefore not only ideal for hunting submarines but also for the wide-area reconnaissance of surface combatants.

Both sonar systems represent the state of the art from ATLAS ELEKTRONIK and, besides newly devel- oped signal processing methods, offer a unified hardware design with the corresponding simplifications in servicing and support. Source navaltoday.com

EA to Provide Torpedo Launcher Systems for Thai, Philippines & Malaysian Navies

SEA is supplying torpedo launchers to the SE Asia market

Cohort company SEA will look to build upon growing demand in South East Asia for its torpedo and decoy launcher systems when it highlights the capability at the Defense and Security exhibition in Ban Mai, Thailand, on November 6-9.

SEA has recently won an order to provide Hyundai Heavy Industries (HHI) in South Korea with Torpedo Launcher Systems (TLS) for two new frigates being built for the Philippines Navy and is also engaged in providing TLS and weapons handling systems for a new class of Combatant Ships under construction for Malaysia. This follows the supply of a TLS for the Royal Thai Navy’s latest frigate, which was built by DSME in South Korea.

SEA is looking to build upon this pedigree with the supply of a triple trainable deck mounted system for a further frigate under consideration by the Royal Thai Navy. In addition, there are several more opportunities in frigate new build and refurbishment projects throughout SE Asia.

One of the major benefits of SEA’s TLS is that they can be configured to fire any NATO standard light weight torpedo, enabling operators to benefit from the flexibility of choosing the best weapon independently and the option of re-configuring during the life of the ship.

The modular nature of the SEA TLS also means that by utilising a common tube selection panel as part of the combat management system the fire control electronics can be adapted to interface with the ship’s decoy launchers as well as the TLS.

SEA’s SE Asia Vice President, Strategic Accounts, David Hinds explains: “Our systems are based on over 30 years s of experience supplying and supporting the UK Royal Navy and there is a growing demand for our launchers in SE Asia.”

In addition, SEA’s torpedo and decoy launchers are being developed to integrate with the company’s thin line KraitArray towed Anti-Submarine Warfare (ASW) sonar as part of a wider detection and countermeasures defence system – Krait Defence System – that uses common software to integrate SEA’s proven range of launchers.

SM-2 standard missile (Provision for)

The RIM-66C/D Standard MR (SM-2MR Block I), was developed in the 1970s and was a key part of the Aegis combat system and New Threat Upgrade (NTU). The SM-2MR introduced inertial and command mid-course guidance. The missile’s autopilot is programmed to fly the most efficient path to the target and can receive course corrections from the ground. Target illumination for semi-active homing is needed only for a few seconds in the terminal phase of the interception. This capability enables the Aegis combat system and the New Threat Upgrade equipped vessels to time share illumination radars, greatly increasing the number of targets that can be engaged at one time. In the middle 1980s, the SM-2MR was deployed via Mk-41 Vertical Launch System (VLS) aboard the USS Bunker Hill, the first U.S. Navy ship to deploy a vertical launcher. VLS has, since 2003, been the only launcher used for the Standard missile in the U.S. Navy aboard Ticonderoga-class cruisers and Arleigh Burke-class destroyers.

The Standard can also be used against ships, either at line-of-sight range using its semi-active homing mode, or over the horizon using inertial guidance and terminal infrared homing.

SM-2 Medium Range Block I, RIM-66C/D:
The RIM-66C was the first version of the Standard missile two. The missile became operational in 1978 with the Aegis combat system fitted to the Ticonderoga class cruiser. The RIM-66D was the SM-2 medium range block I version for the New Threat Upgrade. The SM-2 incorporates a new autopilot giving it inertial guidance in all phases of flight except for the terminal intercept where semi-active radar homing is still used. This version is no longer in service, remaining missiles have either been remanufactured into later models or have been put in storage.

SM-2 Medium Range Block II, RIM-66G/H/J:
The Block II missile introduced in 1983 with a new rocket motor for longer range and a new warhead. The RIM-66G is for the Aegis combat system and the Mk26 missile launcher. The RIM-66H is for Aegis and the Mk41 vertical launcher. The RIM-66J is the version for the New Threat Upgrade. Block II missiles are no longer manufactured, and have been withdrawn from service. The remainder have either been put in storage, or remanufactured into later models.

SM-2 Medium Range Block III/IIIA/IIIB, RIM-66K/L/M:
The RIM-66M is the version of the Standard missile two medium range (SM-2MR) currently in service with the USN aboard Ticonderoga class cruisers, and Arleigh Burke class destroyers. The missile is specifically designed for the Aegis Combat System and the Mk41 Vertical launch system. The Block III missiles differ from earlier blocks by the addition of the MK 45 MOD 9 target detecting device, for improved performance against low altitude targets. The Block IIIB missile additionally has a dual semi-active/infrared seeker for terminal homing. The dual seeker is intended for use in high-ECM environments, against targets over the horizon or with a small radar cross section. The seeker was originally developed for the canceled AIM-7R Sparrow air-to-air missile. All USN Block III and IIIA missiles are to be upgraded to Block IIIB. Block IIIA missiles are operated by the Japanese Maritime Self-Defense Force on its Kongo class and Atago class Aegis destroyers. Aegis equipped vessels in the Spanish and South Korean navies use it as well. The Dutch and German Navies have added it to the Anti-Air Warfare system, which uses the Thales Nederland Active Phased Array Radar and Smart-L radar. South Korean KDX-II destroyers use the block IIIA with a New Threat Upgrade compatible guided missile fire control system. Block III variants for Aegis and arm launchers are designated RIM-66L. Block III missiles for New Threat Upgrade systems is designated RIM-66K. Block IIIB missiles were not produced for the New Threat Upgrade. Blocks IIIA and IIIB are the current production versions. The Thales Nederland STIR 1.8 and 2.4 fire control systems are also supported.

1 × VL-ASROC

The VLA is intended to provide vertical-launch-capable surface combatants with an all-weather, 360-degree quick-reaction, standoff antisubmarine weapon capability. It is carried by Aegis-equipped ships (cruisers and destroyers) equipped with the Mk-41 Vertical Launching System (VLS) and the SQQ-89 ASW Combat System. VLA includes a solid-propellant booster thrust vector control (TVC), and a digital autopilot control (DAC) to guide the missile from a vertical orientation through a pitch-over maneuver into a ballistic trajectory intended to deliver the torpedo to an aim point on the ocean surface. Originally deployed with the Mk-46 Mod 5A(S) torpedo, all VLAs have been upgraded with the Mk-46 Mod 5A (SW) torpedo. This variant of the Mk-46 torpedo provides improved performance in shallow water. With Initial Operational Capability (IOC) of the Mk-54 Lightweight Torpedo in 2010, a program is currently underway to upgrade the VLA inventory with the Mk-54 Lightweight Torpedo. VLAs with Mk-54 torpedoes are planned for fleet delivery in FY 2010.

Nulka active missile decoy

H.T.M.S. Bhumibol Adulyadej (FFG 471) – Surin Lertseethong‎

Nulka is an Australian designed and developed active missile decoy built by an Australian/American collaboration.

It is a rocket propelled, disposable, offboard, active decoy designed to seduce anti-ship missiles away from their targets. It has a unique design in that it hovers in mid air while seducing the incoming anti-ship missile.

The hovering rocket concept was initiated in Australia by the Defence Science and Technology Organisation (DSTO), and the system was designed, developed and then manufactured by AWA Defence Industries (AWADI) (now BAE Systems Australia).

The Nulka consists of the missile itself enclosed in a hermetically sealed canister. This canister is then contained in a Launcher module. Source navy.gov.au

Nulka decoy

The Decoy Launching System (DLS) Mk 53 (NULKA) is a rapid response Active Expendable Decoy (AED) System capable of providing highly effective defense for ships of cruiser size and below against modern radar homing anti-ship missiles. Nulka is being developed in cooperation with Australia (in the Australian Aboriginal dialect, “Nulka” means “be quick!”). It is intended to counter a wide spectrum of present and future radar-guided anti-ship missiles (ASMs) assessed to have passive decoy rejection and active angular deflection electronic countermeasures rejection capabilities. It is designed to over-come the inherent shortfalls of chaff, which are wind dependence, lack of placement flexibility, relatively slow reaction time, and susceptibility to Doppler discrimination.

The system can either be integrated with the Combat System or used with the stand-alone AED Fire Control System. The DLS MK 53 Mod 4 is a modified DLS MK 36 Mod 12 by the addition of two NULKA launching tubes to each of the four MK 137 Mod 2 launchers and a Decoy Launch Processor.

The Nulka decoy employs a broad-band radio frequency repeater mounted atop a hovering rocket platform. After launch, the Nulka decoy radiates a large, ship-like radar cross section while flying a trajectory that seduces and decoys incoming ASMs away from their intended targets. The NULKA decoy is an active offboard decoy which utilizes a broad band radio frequency repeater mounted atop a hovering rocket. The decoy is an autonomous flight vehicle, capable of operating over a wide range of environments and of positioning the payload with a high level of accuracy. The decoy employs the hovering rocket principle and uses a solid state microprocessor autopilot and thrust vector control. The decoy is designed to counter a wide variety of present and future radar Anti-Ship Missile (ASM) guided threats by radiating a large radar cross section signal while flying a ship-like trajectory thus enabling one decoy to counter multiple threats. The flight trajectory is determined by a digital Flight Control Unit mounted immediately above the rocket motor. The combination of thrust and flight control enables successful decoy launches to be accomplished even in severe sea state and high wind conditions. The Processor Power Supply controls the decoy launching by igniting the decoys thermal batteries, monitoring the decoy self check process, downloading the decoy flight program and then igniting the rocket motor. Once launched the decoy operates autonomously and follows the stored flight demands, moving away from the ship at a pre-programmed height and speed and thus presenting an alternative and more attractive target to incoming missiles.Australia is developing the hovering rocket, launcher, and launcher interface unit. The United States is developing the electronic payload and fire control system, which is presently being integrated into the SSDS. Recent upgrades to Nulka include improved payload to reduce cost and modifications to the fire control system to reduce the system’s overall weight.The existing Mk 36 Decoy Launching System is being modified to support Nulka launches. After the Nulka equipment is installed, the system is redesignated as a Mk 53 DLS. Nulka can be used as part of a multi-layer defense system, or it can be used for stand-alone ship protection. The Nulka Decoy System has been successfully tested as a part of the Navy’s Ship Self Defense System (SSDS). Introduction priority will be given to ship classes that are presently without an active electronic warfare suite to provide an increased ASM defense capability. Due to the ever changing complexity of Anti-Ship Cruise Missiles, Nulka will be continually upgraded in order to provide protection to the Fleet. Changes will include technology advancement as well as tactical and technical changes to counter the threat. Source fas.org

Sea Giraffe AMB

3 D Medium range radar 180 km – Sea Giraffe AMB

This multi-role 3D radar provides a full range of functions for simultaneous:

• Air surveillance and tracking, including tracking-on-jam
• Surface surveillance and tracking
• Target classification of both moving and hovering helicopters
• Navigation/close combat capabilities
• Target indication to weapon systems for precision anti-air and anti-surface engagement
• Gunfire support, including high-resolution splash spotting

The radar simultaneously detects small fast-moving targets at all altitudes and in severe clutter. The surface channel gives a high probability of detecting very small targets in close proximity to the surface, for example rib boats and periscopes.

The radar has been proven in all kinds of environments including regions with extensive ducting conditions.

The concurrently processing target returns from multiple digitally shaped narrow receive beams in elevation results in high altitude coverage and monopulse accuracy in elevation. The radar covers the full search volume every second.

In order to relieve operator interaction, Sea Giraffe AMB provides fully automatic operation on both air and surface targets, supported by a variety of different clutter maps and doppler processing to eliminate both land and weather-driven clutter.

Sea Giraffe AMB provides the most comprehensive Electronic Counter-Countermeasure (ECCM) capabilities available today including ultra-low antenna side-lobes.

MAIN HARDWARE UNITS

Today the Sea Giraffe AMB has the designation AN/SPS 77 V(1) for the US Navy’s Littoral Combat Ship, LCS 2/4 and AN/SPS 77 V(2) for LCS 6 and higher.

Sea Giraffe AMB comprises the following main hardware units:

• Antenna Unit (AU)
• Transmitter Unit (TRU)
• Signal and Data Unit (SDU)
• Power Distribution System (PDS)

The following extended capabilities for the Sea Giraffe AMB baseline product configuration are available:

• Stealth Radome
• 360˚ mortar/rocket detection and alert (C-RAM)
• Identification Friend or Foe (IFF) interrogator antenna
• IFF interrogator
• Improved detection range and redundancy with an additional transmitter unit

The stealth radome is built with Frequency Selective Surfaces (FSS) to minimise the Radar Cross Section (RCS) and infrared signature of the above-deck parts of the Sea Giraffe AMB. The radome is capable of carrying equipment on the top, for example an ESM, ELINT and/or a COMINT. The counter rocket, artillery and mortar alert function detects, tracks and classifies very small ballistic objects in severe clutter. The point of impact, the ballistic trajectory as well as the impact position are calculated. A warning signal of impact position is given well in advance, allowing the ship to perform an evasive manoeuvre in order to avoid being hit.
