The PM Modi-led Cabinet Committee on Security (CCS) cleared the project to develop Tejas Mark-2 with prototypes, flight testing and certification at a cost of over Rs 6,500 crore, in addition to the Rs 2,500 crore earlier sanctioned for it, top sources told TOI. With more powerful GE-414engines in the 98 Kilonewton thrust class, the Tejas Mark-2 will have a longer combat range.
