Valour-class frigate (MEKO A-200SAN) – South African Navy

The South African Valour-class frigates are the major surface ships of the South African Navy. Their German manufacturer designates these warships as the MEKO A-200SAN type, member of its MEKO family of naval ships. They were designed and built using principles of stealthy design, including the extensive use of “X-form” structure design in which right angles and vertical surfaces are avoided, and techniques to reduce the infrared signature, such as expelling pre-cooled exhaust gasses just above the waterline. Blohm + Voss, the designers, claim that this class has the radar signature of a vessel one-half her size, 75% less infrared emissions than previous designs, as well as a 20% lower life-cycle cost, 25% lower displacement, and 30% fewer crewmen.

Naming

The MEKO ships of the South African Navy are collectively called the Valour class, and each commemorates an incident of conspicuous bravery. “The symbolism, however, is not in the battle itself, and who the victors were, but the extreme valour shown by the forces involved — both the victors and the defeated” said navy spokesman Commander Brian Stockton

Operation

Frigates are designed to be capable of conducting sustained operations at sea, and they are designed to negotiate sea conditions such as those found off the South African coast. These frigates are designed to carry up to two AgustaWestland SuperLynx 300 helicopters, which will significantly improve and extend its surveillance, operational and sea rescue capabilities. They are be capable of day or night operations in conditions up to Sea State 6

The ships of the Valour class are equipped with an assortment of multi-purpose weapons, each fulfilling a vital role in naval warfare including anti-surface, anti-aircraft and anti-submarine warfare. The ships’ primary anti-surface armament is its MM40 Block 2 Exocet anti-ship missile launchers which give them an anti-ship capability with a range in excess of 72 kilometres (45 mi). According to the International Institute for Strategic Studies, the Navy is planning to upgrade these missiles to Block 3 standard, giving them an effective range of 180 kilometres (110 mi). For closer surface threats the ship can use its OTO Melara 76 mm main gun (range of 16–40 km, depending on the type of ammunition utilised). It is also equipped with a twin Denel 35mm Dual Purpose Gun, two Mk1 Oerlikon 20 mm cannons and two 12.7 mm Rogue remotely operated guns to engage surface targets accurately within a 4 km range.

Systems and Sensors

The frigates were built to a modern stealth design to avoid enemy radar and infrared detection. In addition to these features, the Meko A-200 SAN class is distinctive with a very new propulsion system which is composed by a water-jet drive, in addition to two propellers. Its CODAG-WARP system (COmbined Diesel And Gas turbine-WAter jet and Refined Propellers) consist of a steerable propeller and a water jet. The power is provided by a combination of diesel engines and gas turbines. The propulsion plant can be operated in four modes:

  • I – Economical mode: One diesel engine driving both shafts, maximum propeller speed: 150 rpm.
  • II – Maneuvering mode: Both diesel enginess driving both shafts, maximum propeller speed: 200 rpm.
  • III. CODAG-WARP: Both diesel engines and the gas turbines turned on, maximum propeller speed: 215 rpm.
  • IV – Gas turbine only: Gas turbines powering water jet only.

These frigates are expected to spend about 80% of their at-sea time in modes I and II.

The ship’s steering gear consists of a steering unit and twin semi-balanced underhung rudders. There is an emergency steering station in the superstructure in the event of damage to the bridge and they can also be operated by hand from the steering gear compartment. To improve the ship’s performance in a seaway, they are fitted with a B+V Simplex Compact stabiliser system.

B+V Simplex Compact stabiliser system

This class of warship is conspicuous for a lack of any funnels. To add to their stealth characteristics, the exhaust fumes from the Meko A200’s gas turbines and diesel engines are cooled by spraying water into the exhaust duct and then expelled just above the ship’s waterline, making the frigate almost invisible to most infrared detectors. In 2004, the project officer Rear Admiral (J.G.) Johnny Kamerman explained that the ships’ design features incorporated stealth characteristics that gave the Valour-class very low radar, acoustic, and magnetic signatures. “It is the first major warship in the world with a horizontal exhaust and water jet propulsion, and has an X-form outer hull,” he said. Its manufacturers added that the design has the radar cross-section of a missile patrol boat, a 75% lower infrared signature than previous designs, as well as a 20% lower life-cycle cost, 25% less displacement and 30% fewer crewmen. The lack of funnels also frees up desirable room amidships for armaments, crew quarters, and store rooms.

This class’s combat-management system (CMS), which apparently accounts for about 40 percent of each warship’s cost, was purchased from the Thales Detexis company. The Tavitac system is also fitted to the French Navy’s La Fayette-class frigates, and updated versions are aboard the Saudi Arabian F3000-class air-defence frigates, and the French nuclear-powered aircraft carrier Charles de Gaulle. Kamerman said that he was very proud of the ships’ combat system and the South African ingenuity that went into their design. “Seventy-five percent of the combat suite is home-grown. It’s the largest local-content percentage of all the defence packages. The local content makes testing and integration so much easier. The foreign stuff must be done in a tight time-frame and flying their experts here is expensive. The guys who built our radars are just 40 km away in Stellenbosch,” Kamerman said of Reutech Radar Systems, one of the contractors. Local content also speeded up repair and maintenance. “It is local support in-country, not a local capacity created artificially or a bunch of foreigners flown in.”

Reutech optical radar tracker (ORT)

The RTS 6400 is a 60 km instrumented-range monopulse X-band combined radar and optronics tracking system using a wide-band, high stability Travelling Wave Tube AmplIfier (TWTA) and advanced Doppler signal processing.

The system currently forms a key element of the South African Navy Valour-Class Frigates Combat Suite, for which 9 systems have been delivered into service.

The system has been produced using expertise gained in the development of the ETS 2400 short range Ka-band optronics radar tracker.

The modular nature of the design allows adaptation for alternative configurations of optronic sensor. This capability makes the system eminently suited for most naval fire control applications. Typical sensor configurations include dual field of view 3-5 µm or 8-12 µm Thermal Imaging Sensors, high repetition rate Laser Range-Finders and dual field of view daylight cameras. The system may also be supplied with or without a dedicated console.

The system is able to perform in hostile ECM environments due to a comprehensive ECCM suite. Source reutechradar.com

MRR-3D NG is the latest version of the MRR-3D radar. MRR-3D NG is a G-band multi-role radar designed for 180 km surveillance and self-defence.The radar performs 3D air and 2D surface target detection and tracking, is highly accurate and has short reaction times.

The MRR-3D NG also performs automatic helicopter detection and classification, including pop-up and stationary helicopter over ground, and helicopter short-range control.

The antenna is electronically scanned in elevation and performs 3D accurate tracking to provide target designation (bearing, elevation, range, speed) up to 70°. For rapid deployment of self-defence weapons, the radar delivers tracks with a short reaction time. Then, a dedicated multi-beam pattern is used to provide accurate target designation to the ship or to an active missile system, minimizing target acquisition time for anti-air weapon systems.

For anti-surface warfare, the MRR-3D NG performs splash spotting measurement to support gun firing control. Source thales7seas.com

Planned upgrades

Upgrading to the Exocet MM40 Block 3 standard. The South African Navy is planning (as of May 2013) to upgrade its anti-ship missile capability in order to strike surface targets from 180 km away

Navy_article006Exocet MM40 Block 3 launchersExocet MM40 Block 3 It has an improved range—in excess of 180 kilometres (97 nautical miles)—through the use of a turbojet engine, and includes four air intakes to provide a continuous airflow to the power plant during high-G manoeuvers.Exocet MM40 Block 3 missile

The MM40 Block 3 missile, complete with a Microturbo TRI 40 turbojet engine, began development 2004 and was first tested from a ship in 2010. Improvements to the MM40 Block 3 include internal navigation and GPS upgrades. These updates, combined with a frequency modulated continuous wave radar altimeter, allows for control of the missile’s altitude over various types of terrain. This missile is armed with a 160 kg high explosive/semi-armour piercing warhead and an active radar terminal seeker 9 Additional upgrades include increased evasive capabilities such as the ability to make a 180 degree turn post-launch, allowing the MM40 to evade defense missile systems. These upgraded missiles will be both ship- and ground-launched and will be deployed first onto Forbin (Horizon)-class destroyers and then to La Fayette-class frigates.
