 On 3 September 2009, Loren B. Thompson of the Lexington Institute raised the question of why most of the JSTARS fleet was sitting idle instead of being used to track insurgents in Afghanistan.Thompson states that the JSTARS' radar has an inherent capacity to find what the Army calls 'dismounted' targets—insurgents walking around or placing roadside bombs.Thompson's neutrality has been questioned by some since Lexington Institute has been heavily funded by defense contractors, including Northrop Grumman.
