As you asking I am telling Medium Range Surface to Air Missile (MRSAM) is joint venture in which involved Israel Aerospace Industries and Rafael teaming up with India's Defence Research and Development Organisation and the Indian Air Force to build medium range surface-to-air missiles (MRSAMs), Its deal, worth Rs10,400 crore, would be India's biggest defence JV with a foreign country.

Defence Research and Development Organisation is a partner in the project, but will get only a third (Rs 3,000 crore) of the Rs 10,000 crore. IAI gets the bulk of it, over Rs 7,000 crore, Defence Research and Development Organisation had already developed indigenous air defence systems, such as the Trishul and the Akash.
