Valour class frigate
From Wikipedia, the free encyclopedia
The South African Valour class frigates are the major surface ships of the South African Navy. The German manufacturer designates them as the MEKO A-200SAN class, 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 exiting the exhaust below the waterline. Blohm + Voss, the designers, claim the class has the radar signature of a vessel half its size, 75% less infrared signature than previous designs as well as a 20% lower life cycle cost, 25% less displacement and 30% fewer crew.
Propulsion is from "Combined Diesel And Gas turbine and Waterjet And Refined Propellors" (CODAG WARP).

[edit] History
The four Valour class frigates are a German design by the firm Blohm + Voss, designated as MEKO A-200SAN by the shipbuilders, and are part of Blohm + Voss's MEKO series of frigates. Similar ships are being built in Poland for the Polish Navy.
They are/were built by Blohm + Voss shipyards in Germany, two in Hamburg and the other two in Kiel.
[edit] Armament
Each of the Valour class ships has the following armament:
- One Otobreda 76 mm gun.
- Two 35 mm LIW (Denel) 35DPG dual purpose twin-barreled guns.
- Two Oerlikon 20 mm guns.
- Eight MBDA MM 40 Exocet Block 2 surface-to-surface missiles (mounted in two four-cell launchers).
- Sixteen Umkhonto surface-to-air missiles (mounted in two eight-cell vertical launch systems).
- Torpedoes using two twin 324mm tubes (i.e. four tubes in total).
Each vessel will also carry a Westland Super Lynx medium-sized helicopter. However, the flexibility of the hangar and flight-deck design enables a wide range of helicopter options to fit requirements such as: 2 Westland Super Lynx helicopters (sea state 6 day and night operation); or 1 Westland Super Lynx plus 2 drone UAVs; or 1 Atlas Oryx (sea state 5 day and night operation); or 1 Rooivalk (sea state 5 day and night operation).
