IAF C-130Js are used by special forces for combined Army-Air Force operations.[169] India purchased six C-130Js; however, one crashed at Gwalior on 28 March 2014 while on a training mission, killing all 5 on board and destroying the aircraft.[170][171] The Antonov An-32, known in Indian service as the Sutlej (named after Sutlej River), serves as a medium transport aircraft in the IAF.
