Dude! if you have a brain, you're definitely not using it!
How can Rustom be a replacement for Guardian in the sea roles?
Guardian can venture out to sea for about 1000 kms and stay there for nearly 2 days, while Rustom can only go couple of hundred kms, and stay for much smaller duration. And most important Guadian can drop sonobuoys, which Rustom cannot. Rustom doesn't have the payload capability to carry a large maritime radar or sonobuoy contraptions...
Rustom 2 has endurance of 20+ hours compared to guardian endurance of 27 hours.
Rustom 2 is already being refined. It has been stated by DRDO itself that predator performance is the goal for rustom 2.
Rustom 2 can carry surveillance payload of various types. I acknowledged I'm not aware of sonobuoys by drones so sea guardian has that advantage. But it's no way as cheap as people think.
Sea guardian deal in 2017 was supposed to be 2 billion USD for 22 drone that makes it 110 million per drone while p8i is 260 million a pop. Yet at double the cost p8i is multiple times more effective any which way one computes.
So why is buying 10 more p8i better than 22 guardian at same price.
We have no rush for sea guardian necessity that money should go to rustom 2 development .
And it seems govt is thinking on the same lines with reports of cutting sea guardian order to just 10 drone.
