PLAN, - I don't get it.No but the P-8I gives IN a longer reach and deeper look into the enemy's airspace and seaspace and provide IN a bigger holistic picture, not to mention the offensive capabilities of launching harpoons from a long standoff attack range. It alleviate IN's shortcomings with the number of ships vis a vis PLAN.
Rest, IN don't need it, considering PN.
IN having better options.
Harpoons ?? brahmos a way better than harpoons and with more range also other better options available.
Basically P8i not a major requirement of IN.
P8i is a highly downgraded version of P8a, and all p8 versions better than p8i, mainly becz it is brought during development time[buggy], new ones[4] is better than old 8.
Only advantage of p8i is, it share common payload with romeo and work with sea guardians, except that, a huge expensive item to buy & use.

Other side- IN wanted MRMRA [c235 tata] and some tu22m's, now stuck with p8i [with a negative report from cag] and major beneficiary of this deal was goi, helped to improve indo-us relations [removal of sanctions to civilian nuclear deal]
