NavyRecognition reports that Bulgaria has approved the purchase of two Offshore Patrol Vessels (OPV) from the German firm Lürssen. This is the same company that designed OPVs for Australia and Brunei, but these will be different from the earlier ships.
“…the Bulgarian Navy has a requirement for two modular, multi-role patrol vessels, which would be capable of performing various types of tasks, such as anti-submarine and anti-surface warfare.”
“According to local media, the Bulgarian Ministry of Defense (MoD) has requested a ship that will be armed with one 76mm naval gun, anti-ship and surface-to-air missiles, lightweight torpedos and close-in weapon systems for self-defence. The ship will also have a flight deck to accommodate a medium-sized helicopter.”
Lürssen’s descriptions of their OPV offerings make no mention of an ASW capability, but they do have space for containerized systems that might include some type of towed array sonar. Because of the capabilities required, along with the larger crew required to support them, I would assume that the chosen design is based on the larger 85 or 90 meter offerings. According to the company web site the 90 meter OPV is typically equipped with:
- 1 X 76/62 COMPACT OR 1 X BOFORS 57 MK3
- 4 X MM40 EXOCET OR 4 X RBS 15 MK3 OR 4 X NSM
- 1 VLS MK56 OR RIM-116 RAM
- 2 X DECOY (E.G. MASS OR SWKS)
- 2 X 20MM REMOTE CONTROLLED
- 2 X .50 M2HB MACHINE GUNS
- 1 X 3D SEARCH RADAR
- 1 X FIRE CONTROL RADAR
- 2 X NAV RADAR
- EO/IR SENSORS
- 1X HELICOPTER
- GUIDANCE RADAR
- ESM / ESM
- IFF
- LINK 11/16
- HELICOPTER HANGAR
- HELICOPTER LANDING DECK (11T)
- 2 X 9 M RIB
- 2 X 5,5 M RIB
- STERN RAMP
- 2 CONTAINER SPACES
(Bulgaria does already have Exocet and Sea Sparrow missiles in their inventory.)
Physical Characteristics are:
- DISPLACEMENT: 2,100 T
- LENGTH: 90 M (295 ‘)
- BEAM: 14 M (46′)
- DRAUGHT: 3.5 M (11.5′)
- CREW: 86 (+4 EMBARKED)
- TWO DIESEL ENGINES
- 6,300 KW (8448 HP) (That should result in 21-22 knots–Chuck)
Bulgaria’s Navy is small but growing. They still have a lot of Soviet/Eastern Block equipment. Bulgaria’s coast is on the Black Sea. Other nations bordering the Black sea are Georgia, Romania, Russia, Turkey, and Ukraine. Of these Russia has the strongest naval presence.
No indication yet where the ships will actually be built.
Sounds like a ship we need a couple dozen of.
Since they are about half the size of the OPCs, they do approximate Cutter X.
I think IMO, Bulgaria should go something like a Corvette or an upgunned NSC
Fantastic family of ships. Just the right size for Bulgaria.
Cost for the two ships $593M. not clear if that includes maintenance and/or training in the out years. https://www.marinelink.com/news/bulgaria-orders-patrol-ships-worth-m-483196
SAAB is involved. Presumably they will provide the Combat System, probably a multimode “Sea Giraffe” radar. Looks like they will have a 57mm. This may mean the Torped 47 400 mm light weight torpedo is a possibility. https://www.navalnews.com/naval-news/2020/12/saab-to-equip-bulgarian-navys-new-multipurpose-modular-patrol-vessels/
