PAF aircrafts and surface naval assets will get detected way before than PN submarines. I never implied PN subs are invulnerable to detection, getting detected as late as possible is better than being detected 100's of km's away as it gives less reaction time to change plan's, communicate and coordinate to counter PN subs.
PN subs should be able to get as close as possible to damage IN carrier or harass it to change direction and scoot away.
You could go on submerged tactics and think about midget subs and SSG (N) doing damage to IN carrier instead of Nasr.
Does Nasr follow GPS guidance for target location? if yes, then Carrier is a moving object, not stationary.
Sitting ducks for enemy CM's and other types of missiles.
why can't subs be used to do this job instead, can the launcher be installed in sub? subs have more chances of survival and can fire from a safe distance. You are thinking through a defensive mindset and im thinking through an offensive.
I would be very surprised if a squadron of the aircraft displayed in your avatar showed up armed with AGM-84 to assist PN fight the IN CBG menace.
You could have talked about amphibious tanks floating or MBT's snorkeling but then again, why not put ISI to task and get better results through sabotaging IN facilities and harbors.
Could you throw some light on
deception techniques and tactics used in modern Naval warfare, which could play a part in tackling IN CBG?
