COMCASA (Communications Compatibility and Security Agreement)

India and the U.S. signed the foundational agreement COMCASA (Communications Compatibility and Security Agreement ), on 6 September 2018 on the side-lines of the inaugural 2+2 dialogue.

COMCASA is one of the four foundational agreements that the U.S. signs with allies to facilitate interoperability between militaries and sale of high end technology.


COMCASA is an India-specific version of the Communication and Information on Security Memorandum of Agreement (CISMOA). It comes into force immediately, and is valid for a period 10 years.

It will allow india to access to advanced defence systems and optimally utilize its existing U.S.-origin platforms. The agreement will allow the militaries of both countries to enable greater communications interoperability.

India had already igned the General Security Of Military Information Agreement (GSOMIA) in 2002 and the Logistics Exchange Memorandum of Agreement (LEMOA) in 2016. The last one remaining is the Basic Exchange and Cooperation Agreement for Geo-spatial Cooperation (BECA).
