Pulling up the DRDO for the inordinate delay, the results seen were as stated
Too much time and effort spent in developing engine for tank without meeting success . DRDO looked at outsourcing turret control systems only in mid-’80s after failing to develop it in- house . DRDO did not hand over blueprints and specifications to the manufacturing facility on time . Tank
suffered from poor product quality and sub-optimal performance during development, testing and production stage . Way Ahead DRDO should immediately start work on a Mk II version of the tank to meet the Army’s requirements . Advanced version to be built on a joint development model and foreign collaborators should be roped in to gain expertise . DRDO needs to work on indigenisation of engine, turret and sight and fire control system that it has completely failed to develop.
