The aspect of still making sure it falls well into the domain of Pakistani EEZ is important. In some ways, they could have let the sub get further in and then sent torpedoes towards it but at this point they are probing defenses likely for a future operation (perhaps a small scale SOF insertion to purportedly get the former Mumbai don.. just saying
@Blacklight ) or maybe they want to try and bottle up PN or lay mines ala Ghazi’s actions.
Either way, I think they have been able to get their Akula in and out once but nothing as deep or close. The United States has from 1992 onwards parked their subs right within
Pakistani EEZs with abandon especially the Ohio SSGN during OEF and later reports of subs loitering around during May 2011- Salala
