Turkish OPV (Offshore patrol vessel) designs

[Anmdt]

Delta Marine (Subcontractor of Milgem Project, Also cooperates with TAIS):
84 meters, landing platform, RWS (2-3), fore 76 mm cannon.

RMK Marine (Contract builder of 80 meters coast guard ships, in collaboration with Fincantieri):
Two versions are presented:

-66 meters, 2xRWS, 1xFore cannon, positions for SAM (Stringer type) 2x2 SSM launchers (Multi Mission Corvette)

-66 meters (It is written as such in the brochure but i belive it is either about 56-60 meters or MMC version is about 80 meters), 2xRWS, 1xFore cannon without landing deck (an OPV solution)

MMC-OPV's CAD:

TAIS (Assocciation of ADIK-Sefine-Sedef):
-90 meters OPV, Offspring (Modified version) of Ada-class 3xRWS, 1x Forecannon, Multiple RHIB with stern ramp for Special Forces-COIN Operations. These vessels come in different configurations named compact, lightly armed and full is heavily armed, a medium version exists.

-74 meters version, compact-smaller version of 90 meters OPV:

SEFT Design :
It is slightly overloaded with weapons but assume it as stripped of RAM and SSM launchers. Offers RHIB.

Dearsan (NTPB contractor):
Dearsan has presented some coast-guard vessels, opv and corvette designs in IDEF 19. Enlarged versions of NTPB suits well for this, as well as 90 meters corvette offered for Turkmenistan also possess some potential. 2 of the corvettes presented below can be converted to OPV when needed. However, in my opinion when we need an OPV of +90m, Ada class (as in TCG Ufuk example) can be easily converted for such needs with light arms, Aselsan STOP-Muhafız RWS.

Modified NTPB with landing deck and 2xRWS for Coast Guard is also viable for OPV.

Why don't MILGEM....

 

[Saithan]

Why don't MILGEM....

I think this vessels duty will be guarding civilian vessels or platforms. As such they don’t need heavy armament, just mass to push intruders out. 76 mm is probably meant as a message that it can do harm.

This also means it’ll be treated as coast guard vessel, so we shouldn’t face any embargo.

btw, did we have capability of building vessels out of sight... ?

 

[Brave Janissary]

Yes opv-1900 or 2100 could be offshore patroll vessel but all of us know we need a cheap asw corvette behalf of Milgem class. Just because ;

1- Our fleet age is very more.
2- Our heavy weight naval ship build capacity is low and we build a ships more longer year than others.
3- So we need add vls to milgem and use him asuw general propouse frigate. Already milgem is a bigger for corvette role.

So opv-1900-2100 is good for cheap asw corvette role. İf we integrate him yakamos sonar, 4-8x atmaca , sungur ram version amd 3x2 orka-a lightweight torpedo and powerpack for 28-30 knot it would be great.

And most importan dearsan, rmk and maybe yonca onuk can be build him. So Tais can be build 3x serial i class in the same. When the all of that builds work on istanbul military shipyard will be focus to tf-2000 and modernization of barbaros class.

what if the intent is to let the coast guard navigate this vessel, I’m not versed in the limits of CG, but I don’t think a vessel armed with missiles would fit that definition. If the coast guard could extend their operational range to EEZ it would allow for the TN to focus, on threat generation, and allow for more free room for our cg and Oruç Reis

 

[Anmdt]

Why don't MILGEM....

majority of these OPVs are offsprings of milgem, sharing same structure, same form yet some of them are just tried with new bow forms.
Technically they are lightly armed Ada Class and yes, we can directly derive an OPV from Ada Class like it has happened with TCG Ufuk.

what if the intent is to let the coast guard navigate this vessel, I’m not versed in the limits of CG, but I don’t think a vessel armed with missiles would fit that definition. If the coast guard could extend their operational range to EEZ it would allow for the TN to focus, on threat generation, and allow for more free room for our cg and Oruç Reis

I hardly doubt if CG would be sent to the open seas for protection of EEZs and escorting research vessels, but i think CG should be strengthened with larger vessels similar of Dost Class and 400-600 tonnes boats.
OPVs are fine to operate in TN, they wont replace existing ships they will be introduced additionally as pure Patrol vessels so Ada class can get rid of patrol vessel tag and operate as ASW patrol and escort ship.
moreover, OPV's are prone to be equipped with heavier weapons like SSM or SAM (TN would like it that way) so, they better fit in TN.

 

[Anmdt]

Trimaran OPV by kuasar marine, the middle hull resembles of conventional monohulls ,thus it provides better sea-keeping compared to slender midbody trimarans, suits for OPV roles in high sea states. Side hulls are mainly used to enlarge landing platform and provide additional area for RHIB operations. Beneath of landing platform a Multi mission bay exists, which container sized modules or supplies can be installed, a stern ramp also exists for RAM operations.
Length : 66 meters
Landing platform capable of 10 tonnes aircraft.

 

[Agha Sher]

When are they deciding on a design/quantity?

 

[Anmdt]

When are they deciding on a design/quantity?

It hasn't been announced yet, but sooner or later TN will have OPVs.
