Well
I guess like all other arms of defence forces, navy too would be itching to get its hands on some really cutting edge hardware. considering that most of their ships being manufactured domestically, the flying hardware is the one of the few things, they need to source from abroad. Given how US has fulfilled its commitments on P8i, they may want to try some more of US origin items.
We often look US with suspicion that they may ditch us crippling the capabilities, but if we analyze, the 2 most likely scenarios for US congress to impose such sanctions would be a. Overthrowing Democracy by some dictator (not possible) and b. Another N test (after 123 agreement, this also seems next to impossible). So situation is as good (or as bad) as it is with Russia (with a bad habit of jacking up prices) and France (With Frenchmen trying to converse in Hindi and Indians in French, obviously something gets lost in defence talks
).
Summary: why not try US hardware, if it is available.
