This thread is dedicated to Naval Offshore Patrol Vessels, that are greater from 400 tons to 2,500 tons, and are truly patrol craft. Not multi-role, high threat combat corvettes or frigates. Coast Guards and other civilian agencies are not included.
The US Navy really does not have any such vessels in this displacement range...but numerous other navies do.
These vessels are probably the fastest growing overall calss of vessels in the world today.
I will give four examples here in this first post:
Indian Navy Sukanya Class Patrol vessels:
These are large offshore patrol vessels commisoned into the INdian NAvy between 1989 and 1993. Seven were built in Korea by Korea Tacoma, now part of the Hanjin Group. All are still in service. Their specifications include:
Displacement: 1,890 tons
Length :331 feet
Beam: 38 feet
Speed: 21 knots
Range: 7,000 nmi
Crew: 70
Armament:
1 x 40mm Bofors cannon
2 x 25mm auto cannons
2 x 12.7mm machine guns
Aviation: Hanger and pad
1 x HAL Chetak helicopter
Indian Navy Saryu Class Patrol vessels:
These are larger, modern offshore patrol vessels designed and being built in India and commissioned into the Indian Navy starting in 2013. Four have been commissioned and nine are planned. Their specifications include:
Displacement: 2,300 tons
Length :344 feet
Beam: 42 feet
Speed: 25 knots
Range: 6,000 nmi
Crew: 110
Armament:
1 x 76mm DP naval gun
2 x AK-630 30mm CIWS
2 x 12.7mm machine guns
Aviation: Hanger and pad
1 x HAL Dhruv helicopter
Protector Class OPV for the New Zealand Navy:
.
These two offshore patrol vessels (also known as the Otago class) are operated by the Royal New Zealand Navy (RNZN). Both have been commissioned since 2010. The ships are the HMNZS Otago and the HMNZS Wellington.
The RNZN operates these two vessels to New Zealand Customs Service tasks , tasks for the Department of Conservation and Ministry of Foreign Affairs and Trade, patrol of New Zealand Fisheries, and Maritime patrol duties. The Navy policy was these OPVs carry out resource protection functions in New Zealand's EEZ, the South Pacific and Southern Ocean, and thus free up the two Anzac frigates for other duties. With the capability to carry and sustain a missile armed RNZN helicopter they do have limited higher contingency capabilities.
Displacement: 1,900 tons
Length :276 feet
Beam: 45 feet
Speed: 22 knots
Range: 6,000 nmi
Crew: 110
Armament:
1 x 25 mm stabilised naval gun in Typhoon mount
2 x 12.7mm Browning machine guns
Aviation: Hanger and pad
1 x Seasprite helicopter
Knud Rasmussen Class OPV , Danish Navy:
These offshore patrol vessels operated by the Royal Danish Navy. Two vessels have nbeen built since 2008 and a third is planned. The duties for these vessels include fisheries inspections, environment protection, search and rescue, sovereignty enforcement, icebreaker assignments, towage and salvage operations. TThey do have a helicopter deck but no hangar. BVut the vessels are desinged and fitted to provide refueling for helos.
Displacement: 2,050 tons
Length :235 feet
Beam: 48 feet
Speed: 17 knots
Range: 3,000 nmi
Crew: 43
Armament:
1 x 76mm DP gun
2 x 12.7mm machine guns
8 x RIM-162 ESSM missiles
Aviation: Hanger
1 x Medium Helicopter
