Other thread that additional two were ordered as well now, lastly the sigma corvette which is based on this opv chaises but opv is cheaper and has 30 mm cannon vs 76 mm gun on sigma corvette
pn opv also has fire fighting capability with two water cannons one on each side
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.
