Dude, new frigates are not birthday cakes that you simply pick up at the bakery.
You cannot simply equate and attribute the delay in the frigate project to general bereaucratic sluggishness and inefficiencies in Bangladesh.
Understand that these will be brand new frigates that will serve BN for many decades unlike the used Chinese frigates that BN simply buys, uses and disposes.
These frigates will be larger and the on board systems selected will shape BN's future capabilities and system configurations.
For example, if Chinese weapon systems are selected for these frigates, BN will remain stuck with Chinese systems for decades as it will be difficult to then later integrate Western systems in the future.
If they select Western systems, they have to consider the fact that that costs will be much higher to acquire and maintain the systems (for these frigates and also any future vessels to maintain compatibility) and that no supplier credit will be available. If the govt struggles to continually fund procurement of Western systems and maintain good relations with Western nations over the next few decades, BN's operational readiness will suffer if their systems become predominantly Western.
BN also has to consider what technologies IN and UMN field.
This frigate project is novel to BN and has long lasting implications. They cannot simply rush into it.
Now before
@The Ronin accuses me of setting different standards for BN:
Unlike BAF, BN has not been thumb-twiddling for decades. Despite funding constraints they have maintained decent deterrence capabilities by making smart purchases of used equipment. Unlike BAF, BN will not struggle to find trained manpower to operate brand new hardware as the organisation has steadily expanded by operating the used ships.
