Historical: In the late 1950´s and early 1960´s the Federal
German Technical Office for Armament and Military Purchases drew up
requirements for a new range of tactical trucks for the German Army.
This range was to have consisted of 4, 7 and 10-ton vehicles, some of
which had to be amphibious, 4x4 and 6x6 armoured amphibious load
carriers and an 8x8 reconnaissance vehicle.
In 1964 various German automotive companies were approaches to build the
prototype of this new range of tactical vehicles and in 1965 a Joint
Project Office was established with the following companies undertaking
development work: Büssing, Krupp, Rheinstahl/Henschel,
Klöckner-Humboldt-Deutz and MAN. In addition Daimler-Benz developed some
vehicles. After some prototypes had been completed it was decided in
1970 that the Joint Project Office would concentrate on the unarmoured
trucks while Daimler Benz concentrated on the armoured vehicles.
In the late 1960´s it was decided to stretch out the development
programme and the first vehicles to enter production was the 8x8
reconnaissance vehicle which was called the Luchs.
In 1972 it was decided that the trucks would have a diesel rather than a
multi-fuel engine and the amphibious requirement was also dropped. After
trials between the Joint Project Office prototypes and the Daimler Benz
prototypes, a contract was awarded MAN in December 1975 for a total of
8.385 5-ton, 7-ton and 10-ton trucks. Production of these known as the
KAT1 series commenced
early in 1976 and was completed around 1980.
The SX and HX range is derived from the KAT1. There are 4x4, 6x6 and 8x8
variants. All are air-transportable by C-130 Hercules. A 10x10
demonstrator with a 1000 BHP engine has also been produced. The SX and
HX shares some technologies with the FX and LX families.
The British armed forces have ordered
large numbers of MAN SX and MAN HX trucks to replace their fleet of
Foden, Bedford, and DAF Trucks. 7285 had been ordered by April 2010.
An 8x8 heavy recovery version has also been
built; the British army bought 288.
