MN lacks true guided missile frigates, meaning they lack proper air defense in their frigate. Despite building their own indigenous ship building capability.
With size of its EEZ and sea area, MN is rather undersized and under armed.
Inducting handful of Corvettes, FACs, a lone submarine, and 4 frigates ( among them 2 of them are old Type52H1s) are not indication outstripping anyone.
However, there's no provision for Bangladesh to underestimate anyone.
