1. JF -17 has potent air to surface radars and can easily identify any indian ship and target it with multiple antiship missiles, each one can easily carry 2-3 antiship missiles armed with sd-10BVRs and PL-5, images are everywhere in this configuration, thunder range is in excess of 1000 km, while our boarders are 300km from sea shore and thats would we need to protect to keep our oil line open
2. AWECS, Orions, long range radars
3. regarding babur thats a nuclear triad thing
4. you dont need hit a merchant ship, just say you will..lol, even if we do an AIP sub can disappear within hours, unless IN is thinking to petrol/escort EVERYSHIP
lol it doesnt have the numbers to escort even 1/100 ships
5. Zarb is the name of coastal battery that can protect our sea shores by hitting anything within 400kms
6. PAF is air wing of the navy, likley 2 dedicated sq will be kept
war dont work as 1:1 even if pakistan matches india with 1:5 ratio or 1:10 its more than enough to cause havoc to indian economy.
fact is indian cannot do a blockade, as Pakistan can do that/reply with in gazillion of ways
if india start with hitting a merchant ship, it would be fair game for us to hit any indian ship any where
you can do blockade without sinking/boarding a ship
