Should Pakistan Try to Lease a Turkish Type 209 Submarine?

Bhai even if u upgrade it it also a old it's hull inside pipes are old it's hull cannot stand more than 250 feet with single hulled

You are still mixing up feet and meters. 250ft is 75m. Even the old 500-odd ton Type 206s dove to more than 200 m and the Type 207 to 180m. Only the very first post-war German boats (Type 205) were limited to 100m. TR-1700 delivered to Argentina has diving depth of 300 m. Type 210 for Norway has 200 m.

Untill when you keep old upgraded thinking with this entire PN ships are old

sir, but A-90 was given with TOT and licence to export it as well... why more A-90s was not made?? @Rashid Mahmood

No Sir, A-90B was not given with an export licence.
TOT doesn't mean that we completely build the sub here. We only assembled the A90 here.

Why go for a comparatively old design that will eventually be supplanted or made redundant with the 8 Chinese SSPs? Maybe a better route would be to think long-term and perhaps invest in littoral waters SSKs instead? Think of the HDW Type 210mod; imagine having three of these submarines patrolling our littoral waters and acting as a clear A2/AD asset?

I don't know, but @Tank131 do you remember the days when the PN was actually considering these smaller littoral SSKs to supplement its SSP fleet? I recall the HDW Type 210mod and DCNS Andrasta being considered. IMHO, instead of buying a mothballed SSK and spend on refurbishing and potentially upgrading it, may be better to go the mini-SSK route.
