During the talks External Affairs Minister Sushma Swaraj and Defence Minister Nirmala Sitharaman had with US Secretary of State Michael R Pompeo and Defence Secretary James Mattis, the two countries also chose to set up hotlines between them.
COMCASA opens the door for real-time strategic cooperation between New Delhi and Washington, especially at a time when both nations are wary of Beijing's growing belligerence in the Indo-Pacific region, specifically in the maritime domain.
The COMCASA will facilitate India to obtain critical defence technologies from the United States, and access critical communication network to ensure interoperability among the USA and the Indian armed forces.
A Pentagon official last month threatened to impose sanctions on India if it goes ahead with its $6 billion purchase of the Russian S-400 missile defense system.
Swaraj also asserted that the dialogue reflected the desire of leadership of the two countries to further elevate the bilateral strategic communication on cross-cutting defence and security issues.
The United States has imposed sweeping sanctions on Russian Federation, under which any country engaged with its defense and intelligence sectors could face secondary USA sanctions.
Most recently, the US has taken issue with India's purchase of oil from Iran and its planned acquisition of a Russian missile defense system.
Despite Trump's efforts, government officials in India, the world's third-biggest oil importer and Iran's top oil client after China, say that it would be hard to fully halt supplies from Tehran.
In another article in the magazine, think-tank scholars Atman Trivedi and Aparna Pande argued that just as the USA is warming up to India, India is starting to get cold feet about the whole idea.

After Trump left the room, Woodward wrote, Mattis told people that Trump understood the topic like a "fifth or sixth-grader". It's either that or an orange jumpsuit", Dowd is quoted telling the president. "Let's kill the f-ing lot of them".
"We see the US-India relationship as a natural partnership between the world's two largest democracies, a partnership that is based on the convergence of enduring strategic interests and shared respect for the rules-based order", Mattis said.
India however is highly reliant on Iranian crude imports. "India has a clear idea of itself as a major regional power.so it needs an autonomous perspective on ties with third countries", Joshi said.
The Trump White House has said that it seeks to bring Iran's oil sales supposedly down to "zero".
If the S-400 deal is finalised, India has signalled it will ask Washington for a special waiver from sanctions, though a U.S. official last week said there is no guarantee it would do so.
Before coming to India, Pompeo held talks in Islamabad with Pakistan's new government and senior most generals. The mechanism was agreed upon by US President Donald Trump and Indian Prime Minister Narendra Modi over the phone in August past year, but will only materialize after being cancelled twice for various reasons in April and July.
Economic links have blossomed since India's market reforms in the early 1990s.
A recent Foreign Policy piece argued "America shouldn't miss its chance with India".
New Delhi has formerly said it will not comply with unilateral sanctions on Tehran. "But the gap will remain and I urge them to do all they can to narrow it".
"India has been doing so till now, and it will manage similarly in the future", Joshi said.
