True but we're not in a firepower contest with India. That contest is a non-starter.
These destroyers (and any that succeed it) are supposed to be a deterrence and denial measure for China's blue-water Navy and CBG, probably in the Arabian Sea through which China's oil comes from. That lane is probably going to be a little less strategic now - now that pumping oil though Gwadar and CPEC are becoming a reality.
Are our top-tier yards capable of building a Kolkata class destroyer? Sure.
Considering that at least the hull of the follow on class (P17) succeeding this destroyer is going to be built at an inefficient British colonial-era facility with antiquated production techniques (Garden Reach Shipyard, Calcutta), our yards are way more modern and could easily do it and in a much shorter schedule. Most Kolkata class boats were built at Mazagaon Docks in Bombay and this is the largest ships they had built so far (7400 tonnes).
But what for? With the out-of-proportion expenditure on this piece of armament we could build hundreds of schools and educate our kids to build the foundation of our society. That way the money wouldn't be wasted at some politician's Swiss or Singapore bank account and would build an egalitarian, stable society with an able and educated workforce.
We'd rather not waste money on this type of 'bragging rights' that is going to see hardly any use - if ever.
Bangladesh foreign policy in any case is a defensive one. We don't seek any arms race or conflict with anyone. We'd rather resolve issues across the table and build leverage with our trading power. Picking fights with your neighboring countries is a losing game.
We should rather concentrate on feeding, clothing and housing our people first and give them a shot at a healthier, better future. If you watch our HR indicators of late - you'll see that we're more or less succeeding....
The Chinese carrier Liaoning (ex Russian Varyag) is more modern (next generation) and one-notch larger (65,000 tonnes) than the Indian Carrier Vikramaditya (refurbished Russian carrier Admiral Gorshkov, 45,000 tonnes). The new Indian Carrier being built at Kochi is about the same size.
Plus the Chinese carrier carries larger number (50) and more potent fighters (Su-27 naval variant copy, J-15?) than the Indian carriers (about 30 including Mig-29k).
I have severe reservations about the Vikramaditya purchase. That ship was a unreliable rusting hulk when they purchased it. And the Russians milked them for every penny of what it was worth. Indians unfortunately at that time had few other options than this overpriced hulk. There were issues with the boilers. Seven out of Eight of its boilers failed during trials. Now nationalistic fanboys in India will bring out their pompoms and sing the praises of this purchase - but if you ask me the only gainers were the defense minister Antony (the white Lungi guy) and everyone else up the food chain above him. Anyway its their deal....
