Indian indigenous Arjun MBT development history is a facinating story of Indian quest to develop a formidable Tank. The main battle tank MBT-80 which is now called MBT Arjun was conceived by the Indian Army after it realised the futility of its tanks mainly in desert conditions, during the 1971 war. 1972 – 1975 In October 1970 a symposium was held on the Indian Main Battle Tank (MBT) at Armoured Corps Center and School. It was attended by the representatives from Indian Army General Staff (GS), Defence Research and Development Organisation DRDO), Director General Quality Assurance (DGQA) and Department of Defence Production (DODP). The main aim of the symposium was to formulate GSQR for future Indian MBT. The first draft of Qualitative Requirement (QR) was prepared by Armoured Corps Directorate and discussed with Vice Chief of Army Staff (VCOAS). The first General Staff Qualitative Requirement (GSQR) was issued in August 1972 as QR No. 326 for the design and development of MBT. The QR 326 was not exhaustive and with regard to specifications but featured only skeleton specifications. The design and development of MBT based on GSQR No. 326 was taken up by the Combat Vehicle Research and Development Establishment (CVRDE). The initial outlay of Rs. 15.50 Crore was sanctioned vide the Government of India (GOI) letter dated 02 May, 1974. Project Development Certification (PDC) of the project was 10 years from the date of sanction. The MBT was to be designed around imported engine as the design and development experience to create a tank engine was not available within the time frame of the project. In 1974, DRDO had to take up design and development of a tank engine as Government of India could not import a tank engine because of political and other reasons.
