1. Your point is well taken (and my apologies if I've understood you wrong) however Bangladesh' current naval doctrine demands ships like the USCG Rush. As I have noted in my other posts - Bangladesh' main threat is not strategic (unlike blue water navies) but rather protecting EEZ assets (such as fishery, hydrocarbon deposits) and protecting trading lanes from interference by other navies while doing double duty as a defense platform. You may be right that,@Bilal9
you do understand I'm not comparing INS Shivalik with the hybrid,right??I'm merely saying that just integrating missiles with some large ship doesn't make it a Frigate.a Frigate is a mean machine,quite heavily armed as well as should have to protect itself from various kinds of threat.present day frigates generally has low signature as well as various electronic suits to protect,apart from missiles and ASW rockets and torpedos.integrating missiles in a ship generally makes it a floating missile launch pad,thats it.
and then,i pointed out how Myanmar was making frigates.thats the realistic approach.if BD was too poor to afford frigates,I'd understand.role changing of a warship generally doesn't fare better.when you're living in a hostile neighbourhood,inducting these handicapped intrument generally bog you down further.
and please,I'm a bengali.so you may communicate using bengali.no need to use hindi.
'integrating missiles in a ship generally makes it a floating missile launch pad',
However you have to keep in mind that the USCG WHEC class has been (and is still being) used for overseas defense related duties overseas (especially IRAQ). Although the WHEC class did not have VLS systems - ships of similar size in the US Navy do have it. Re-fitting the WHEC class with VLS may be out of the question because of the complication regarding CG and difficulty of re-engineering etc. However fitting of lighter FM-90 AShM (and other related modern Chinese sensors and weapons electronics suites) may be relatively easier.
Case in point is that the BNS BangaBandhu was recently re-fitted with the FM-90 although the ship was made in Korea and generally built for American missile and electronic suites and systems in mind. Also the WHEC class ships are about 500~700 tons heavier than the BangaBandhu. So fitting FM-90's are not technically an issue on WHECs.
The WHEC class was well-armed for what it's role was - which was extended EEZ patrol as well as drug busts off South American locations in international waters. It did have a couple of Phalanx CIWS systems on board as well as an OTOBREDA 76mm super rapid gun which is plenty of firepower for those duties. Whether Bangladesh will opt to equip the ex-WHEC class ships with FM90 type AShM remains a conjecture but you can be assured it will happen if they do see UNIFIL duties.
2. Bangladesh needs to use its naval forces for United Nations UNIFIL duties (such as in Lebanon) which may account for its somewhat over-sized navy in relation to its needs in the Bay of Bengal area. Almost every new ship that Bangladesh has purchased in the last five years has seen UNIFIL duties in either Africa, Lebanon or wherever they are called for. Same for Army and Air-force.
3. Although spending money on arms is wonderful for pocketbooks of higher ups in Govt., one has to moderate it with internal Bangladeshi politics. I believe the Bangladeshi press is quite vocal about such military overspend as we have other practical budgetary priorities such as public education, nutrition and hygiene. On top of that - although we have immense respect for our fighting forces, we don't have that much of a 'fauji' culture internally that our public lives revolve around our Army, Navy or Air-force like some countries in the Middle East etc. and neighboring countries like Myanmar.
4. I don't know much about Myanmar's frigate program of the 'Aung Zeya' class - although I've heard that they used Chinese ToT in building those - still quite an achievement for their yards. Also - I've heard that one of the Aung Zeya class ships may have had some structural issue. Maybe our Myanmarese friends can enlighten us on how the program proceeded and what roadblocks they encountered.
