The US and India have grown closer over the past decade, and they took another major step forward in September 2018 with the signing of a communications agreement that will improve their ability to coordinate military operations — like hunting down submarines.
Defense Secretary Jim Mattis and Secretary of State Mike Pompeo met with their Indian counterparts, Nirmala Sitharaman and Sushma Swaraj, respectively, on Sept. 6, 2018, for the long-delayed inaugural 2+2 ministerial dialogue.
The meeting produced a raft of agreements. Perhaps the most important was the Communications, Compatibility, and Security Agreement, or COMCASA, which "will facilitate access to advanced defense systems and enable India to optimally utilize its existing US-origin platforms," according to a joint statement.
The deal — one of several foundational agreements the US and India have been discussing for nearly two decades — took years to negotiate, delayed by political factors in India and concerns about opening Indian communications to the US.
The US wants to ensure sensitive equipment isn't leaked to other countries — like Russia, with which India has longstanding defense ties — while India wants to ensure its classified information isn't shared without consent.
But the lack of an agreement limited what the US could share.
"The case that the US has been making to India is that some of the more advanced military platforms that we've been selling them, we actually have to remove the advanced communications" systems on them because they can't be sold to countries that haven't signed a COMCASA agreement, said Jeff Smith, a research fellow for South Asia at the Heritage Foundation, in an interview in late August 2018.

Mattis, along with U.S. Secretary of State Michael Pompeo, Chairman of the Joint Chiefs of Staff Gen. Joseph F. Dunford and other top U.S. officials met with Modi following the first ever U.S.-India 2+2 ministerial dialogue, where Mattis and Pompeo met with their Indian counterparts.
"So that even when we're doing joint exercises together, we have to use older, more outdated communications channels when our two militaries are communicating with one another, and it just makes things more difficult," Smith added.
And it wasn't just the US. A Japanese official said in 2017 that communications between that country's navy and the Indian navy were limited to voice transmissions, and there was no satellite link that would allow them to share monitor displays in on-board command centers.
With COMCASA in place, India can now work toward greater interoperability with the US and other partners.
"COMCASA is a legal technology enabler that will facilitate our access to advanced defense systems and enable us to optimally utilize our existing US-origin platforms like C-130J Super Hercules and P-8I Poseidon maritime patrol aircraft," an official told The Times of India.
Importantly for India, the agreement opens access to new technology and weapons that use secure military communications — like the armed Sea Guardian drone, which India will be the first non-NATO country to get. Sea Guardians come with advanced GPS, an Identification Friend or Foe system, and a VHF radio system, which can thwart jamming or spoofing.
The deal also facilitates information sharing via secure data links and Common Tactical Picture, which would allow Indian forces to share data with the US and other friendly countries during exercises and operations.
"If a US warship or aircraft detects a Chinese submarine in the Indian Ocean, for instance, it can tell us through COMCASA-protected equipment in real-time, and vice-versa," a source told The Times of India.
'The bells and whistles ... didn't necessary come with it'
Signing COMCASA has been cast as part of a broader strategic advance by India, binding it closer to the US and facilitating more exchanges with other partner forces. (Some have suggested the deal lowers the likelihood the US will sanction India for purchasing the Russian-made S-400 air-defense system.)
The agreement itself will facilitate more secure communications and data exchanges and opens a path for future improvements, but there are other issues hanging over India's ability to work with its partners.

India purchased the aircraft through direct commercial sales rather than through foreign military sales, said Bryan Clark, a senior fellow at the Center for Strategic and Budgetary Assessments, in an interview at the end of August 2018.
"As a result a lot of the bells and whistles, the extra stuff that goes with a new airplane — the mission systems, like the radio systems, and the radars and the sonobuoys and all the equipment that you'd get with an airplane like that — didn't necessary come with it, and they're going to have to buy that separately," Clark said.
"Signing this agreement means there's an opportunity to share the same data-transfer protocols or to use the same communications systems," Clark said. But both sides would need to already have the systems in question in order to take advantage of the new access.
"So the Indians would still have to buy the systems that would enable them to be interoperable," Clark said.
Smith said a "fundamental change" in the US-India defense-sales relationship was unlikely, but having COMCASA in place would make US-made systems more attractive and allow India to purchase a broader range of gear.
"At least now India can get the full suite of whatever platforms they're looking at," he said.
