Tank Ex or MBT Ex was the code name of the main battle tank developed by the India and Defence Research and Development Organisation (DRDO) in 2002. It was rumoured to be called Karna after one of the heroes of the Indian epic The Mahabharata. Tank Ex was developed as a second attempt after Ajeya (upgraded T-72) by DRDO to harness its technology spin-offs. The Tank Ex successfully underwent six months of trials but was rejected by the Indian Army. At least two prototypes have been built.
