U are absolutely right and we should not forget probable Naval stations of IN in Africa and Mauritius, in order to threaten/strike them we should have lonf range missiles both for naval and air assets.If I was incharge of the PN I would focus more on building Tabuk Class sized Corvettes and MILDEN sized Submarines. Aiming for a minimum of 16 of each rather than building large warships beyond 4000+ TNs.
It is absolutely crucial and in Pakistan geostrategic interest to expand the Babur Cruise Missiles range to 1500-2000 KM minimum. Even NK just tested a similar ranged cruise missile.
Eventually even Corvette sized crafts could be equipped with 8 Vertical Launched Super Baburs. The Russians are already expanding upon this concept. They have launched long range Kaliber cruise missiles from Corvettes in the black sea unto targets in Syria.
Imagine PN Corvettes stationed in the strait of Hormuz could target and strike IN warships sitting in Mumbai with long range Super Baburs.
On lighter note we as a nation have had planning issues since creation of country in every field, our beloved USA has think tanks, u do not need much resources as people in think tanks may work on semi volunteer basis i.e from economy to defense and even in sports. Every time Almighty shall not rescue us.I think military brass of pak and Bangladesh Should be replaced by pdf folks since they can revolutionize the forces and bring them into 24th century at minimum may be 30th
Kidding do not take it toooo seriously
