All the things related to the LPC will be discussed here from now on. (PDF file of the tender added below)

Google Translation:-

The Turkish defense industry made a bid for the Heavy Missile Patrol Ship (LPC) Tender of the Bangladesh Navy with MİLGEM ADA Class Corvette and ATMACA Anti-Ship Missile.

Bangladesh launched a tender for the procurement of large-type patrol ships (LPC) equipped with 8 Anti-Ship Missiles (AShM) in response to the needs of the Bangladesh Naval Forces Command. According to the Bangladesh press; Held on 26-28 October 2020, the online date 6. Defense Port Turkey during the event, Turkey's ADA ATMACA Anti-ship cruise missile equipped with a tender was announced to offer with Class Corvettes.

According to the information obtained; The Bangladesh Navy has shortlisted the ADA Class Corvette and the ATMACA Anti-Ship Missile System. Bangladesh wants the ships to be built in domestic shipyards.

Four ADA Class Corvettes, which have been produced for the Turkish Naval Forces Command so far, draw attention especially for their submarine defense warfare (DSH) capabilities. The first three of the ADA Class Corvettes have the US production Harpoon Block II Anti-Ship Missile, while the last corvette, the TCG KINALIADA (F-514), has both the Harpoon Block II and the Roketsan ATMACA Anti-Ship Missile, developed with domestic facilities. Mass production ATMACA deliveries to the Turkish Naval Forces are planned to begin in 2021.

In addition, construction activities for Pakistan of four warships (Jannah Class Frigates) similar to the ADA Class Corvette design continue. Two of the four corvettes in Turkey and two in Karachi Shipyard / being produced in Pakistan.

On the other hand, the construction activities of TCG ISTANBUL (F-515), the first frigate within the scope of the MİLGEM I Class Fırakteyn project, which is a continuation of the MİLGEM ADA Class Corvette Project, continues.

@anmdt posted some Corvette designs in another thread that looked pretty awesome too for BDN.
Yes but probably Ada class will be offered as-is.
I wonder if gas turbines will be delivered too. It would be nicer to see actual requirements to make comment on it.

Especially Durjoy class is classified as LPC (65 meters 650~tons), It is a great opportunity to push for alternative and smaller designs of Milgem (of 78-85 meters length ~1200-1600 tons) to meet their needs in smaller sizes.

Diesel engines (2 or 4 with two propellers),
Self air-defense (CIWS - Short range SAM)
Forgot to add + mine laying capability. (Not a big deal to include)

The chart also includes reference and suggested design submission, thus as long as a reference design is built, it is assumed as base for the target.
C1200 (Corvette 78) fits perfectly to all requirements:
Main gun can be replaced with 30 MM stop, Gökdeniz CIWS might be added, there is space enough for all.

Should we worry that there is reference to US/German/French/UK products ?

History has shown us that EU and US don't give export permit just to favorize their own close partners.

There are also examples of Turkish products like Smash (several other i have seen among the document), i assumed those are given as examples, generally equipment is restricted as "western origin".

Who knows but there wasn't any issues with LM2500, Smart-S and MTU engines + RENK gearbox sold to Pakistan.

Yes, true.

But wasn't BD considered to be an important member of QUAD, and thus I would say there are grounds for mistrust. They'd favor their own "western" allies in a tender bidding. To establish more firm hold on BD in the power struggle.

If we're going to deliver the corvette with engine then our western allies may raise the price, or unfairly give a much bigger discount to competitive bidder (e.g. Italy).

Am I overthinking this ?

If it was going to be produced in home country, then we could worry about subsidizing, not directly but indirectly because they would save human resources compared to us, using personnel from shipyard but not the engine/part manufacturer.
In this case, for whichever foreign part bundled on Turkish solution,or their (competitors) own solution; the technicians and personnel would need to travel to Bangladesh.

Not less than 700 tons. That's minimum requirement. No problem if the vessel has bigger displacement.


Could you link it brother

I think he did.

Another interesting request for a corvette is 30 mm main gun. What's wrong with 76mm?

Not quite sure but probably because it is designed as an ASuW patrol craft to deploy AShM and smaller gun is considered enough?
There is also requirement of 2x 12.7 mm RWS , maybe these guns altogether intended for OPV role of the ship.
The secondary role of the LPCs will be to perform coastal patrol and constabulary duties within Exclusive Economic Zone (EEZ)

Ada-class looks like an overkill for given specs, probably this ASuW variant by TAIS has been tailored for Bangladesh along with newly introduced OPV class & LPC class: Also showcased in SAHA Expo without any names given
1x Smash
2x Stamp
Smart-S / Mar-D
AKR-D Block A1
1x RHIB
8x AShM
Tonnage is given as 660 for standard, in full load exceeds 700,
All but range and endurance fits to the requirements in RfP;
Range is given as 1500 NM at 19 Knots, in excess of 2000 NM at 14-15 Knots (not available on paper)
Endurance is given as 7, it may include additional personnel, so with core personnel may go up to 10.

I think ASFAT will be submitting their own design, not TAIS'.
