Our maritime ISR capability is still under planning stages. Some of it has been built into the Dornier aircraft, but the main capability will be taken up after the AWACS program.
The IN has 3 programs, 1 is an indigenous DRDO design based on the Dornier, the 2nd and 3rd are imported. The 2nd one is on a medium-sized aircraft and the 3rd is the P-8I. So, short, medium and long range.
The MRMRA is yet to be cleared.
India is vulnerable when one views it through its maritime domain of a coastline of 7,516 km, touching nine states and four union territories

It may be indigenised, but I don't know yet.
