Valour class patrol corvettes
|
|
The South African Valour class patrol corvettes will be (as of early 2004) the major surface units of the South African Navy. The German manufacturer designates them as the MEKO A-200SAN class, successors to the MEKO class. They are built to a stealthy design, through the extensive use of "X-form" structure design in which right angles 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 cross section 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.

History
The four Valour class patrol corvettes 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.
Armament
Each of the Valour class ships has the following armament:
- One 76 mm Oto Breda 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 launchers).
- 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).
