US regularly conducts operational challenges in Indian EEZ

The US does not recognise India's territorial claims with regard to territorial waters and exclusive economic zone and has been conducting operational challenges to such claims on a regular interval, US Defence Department officials said.
"India maintains an excessive maritime claim requiring prior consent for military exercises or manoeuvres in its Exclusive Economic Zone (EEZ)," a senior Defence Department official told PTI when asked about a recent White House statement that US has challenged India's territorial claims in EEZs.
"The US diplomatically protested the claim in 2007 and conducted operational challenges in 1999, 2001, and 2008 through 2014," said the official, who requested anonymity.

While it is not known what was India's response in these operational challenges by the US naval forces, publicly available information says the United States does not recognise this India's territorial claims since 1976 with regard to territorial waters, continental shelf, exclusive economic zone and other maritime zones.
The US first protested way back in 1976, and then in 1983 and 1997.
And as such the Pentagon has been regularly conducting operational assertions since 1985.

India requires foreign warships to provide notice before entering its territorial water as defined and identified by it.
The Pentagon said it has been carrying out operational challenges in territorial sea, which India says is its own and as such foreign warships need to seek permission from it and notify it, since 1985.

Its warships entered India's EEZ without notifying India multiple times between 1985 through 1989.
After a gap of two years, US warships is believed to have entered Indian EEZs without notifying India or seeking permission from it in 1991, through 1994, 1996, 1997, 1999, 2001, 2007 and 2011.
US warships did the same multiple times in 2014.
