Actually youre into sometving very fundamental here.
Bangladesh is geographically small and flat riverine deltaland. It will be easy for a potent enemy to strike down critical BAF and BA bases and installations, because Bangladesh lacks strategic depth.
The best way to deter an adversay, is to always have some potent strategic weapons which are put of reach of first-strike from an anemy. In this regard, the BD NAVY is to play the key role in advancing a second strike doctrine and its correspondent procyrement policy.
Ideally BD would have nukes for second strike, but thats not realistic by any means. But what is realistc is to have enough Surface and Subsurface marine vessels that can strike out vital enemey installations.

- hypersonic missiles
