Lockheed Martin will deliver 24 PstarER extended range portable search and target acquisition radars to Switzerland between July and December 2004. The radar sees its range stretched out from 20 km to 30 km and will typically be used in conjunction with Switzerland's Stingers. They will be deployed on customised trailers carrying a mast, which allow the radar antenna to be elevated to a more effective height.
