Splitterskyddad EnhetsPlattform

The SEP modular armoured vehicle (Splitterskyddad enhetsplattform), Swedish for "Fragmentation Protected Standard Platform", is a hybrid diesel-electric powered armoured fighting vehicle developed by BAE Systems AB. The vehicle is codenamed "Thor". The first demonstration models were produced in 2000 (tracked) and 2003 (wheeled). It was originally contracted by the Swedish Defence Materiel Administration. Later Sweden decided to buy the Finnish Patria AMV. As of July 2009, no country is considering the vehicle.

Development
The project began in 1994. Sweden's original requirement was 1600 vehicles. The vehicles were planned to enter service in 2014 and the modular payload configuration was expected to allow up to 24 variants.

In February 2008, the Swedish Armed Forces announced the cancellation of the SEP programme. The reasons stated were a 'lack of an international collaborative partner' which prevented the Swedish armed forces from continuing the project alone. The vehicle was dropped from the British FRES programme in July 2007.

In 2009 BAE announced that Kongsberg Devotek would develop gears and transmissions for the vehicle.
