Bangladesh Navy ASuW LPC Project (Cancelled)

Beautiful. We need it asap

After selection of Smash 30mm and MoU with Roketsan i think the possibility for Turkey to win this contract has increased.

Atmaca will be great.But won't it be better if we select a stealth anti ship missile? We can consider teaso mk2/e as we are already operating otomat.

It will be the best option for any future warship of BN. But don't know if MBDA has a export version of this missile yet.

It's only a matter of time.(if they don't have a export version)

Marte missile might be offered too. Really curious about Italian and Korean offer for the LPC. So far we only saw few Turkish offers.

If it were upto me I would pursue trying to source a hypersonic missile instead of anything stealth. Kh 45 for ex.

Those overhyped hypersonics will be useless within 2 decades thanks to DEW's.

And I don't expect bondhu's to have Brahmos 2 in active service before 2035.And when they do,only a handful of their ships will have hypersonic capability at first.I don't think we need to think about hypersonic defence or having our own hypersonic missiles at least for now.Anything hypersonic will be a waste of our limited resources.It will be better if we stick with stealthy and cheap subsonics which we can easily replace.

The reason I’m not on the stealth camp is because revolution in radar tech is coming and stealth will become redundant. This is why America is also focusing on speed on their next gen platforms

That's exactly why you should be in the subsonic camp.If both stealth and speed doesn't work then I don't see any logic in expensive hypersonic missiles for BN.

Rather than spending on missiles we should focus on our submarine fleet.Many western navies use subs as their main offensive platform.We can also spend on UUV's.

Only Zircon is available and not even allowed for export yet. Current ideal choice would be a supersonic missile.

About hypersonic missiles, there’s currently no known system for defence against them.
as for subs. I agree. We’re far better off having an offensive submarine fleet to engage adversities who’re involved in area denial

IIRC, the SIGMA's have the lowest operating costs of all Indonesian navy surface combatants, maybe BN could consider this in mind.

prolly for this particular project only, most of BN surface combatants uses C-802 already.

 

[Anmdt]

BN is also aiming to get ships from the west, C-802 is less likely to be on those.

If they are not adding exocet or otomat to diversify in future, it is for best to set a common AShM at this stage for vessels originating from west.

IIRC, the SIGMA's have the lowest operating costs of all Indonesian navy surface combatants, maybe BN could consider this in mind.

Maintenance cost of the ships quadratically increases after 10th year. The increase becomes dramatic after 30 years. (Very rough numbers, assuming the expected life is 40)

I don't know ages of the major combatants of the Indonesian Navy but Sigmas are the newest if i recall correctly, thus it is natural to expect that. The older the ship, the more it costs maintenance in per year basis.

Also the new equipment have built-in self-diagnosis that helps technicians to find the root cause and fix it in simplest way directly, instead of trial and error combined with 6th sense in the older equipment.
