Mastery of the littoral cannot be presumed. It does not derive directly from command of the high seas. It is an objective which requires our focused skills and resources. ONUK MRTP34 “Fast Patrol / Attack Craft” has been designed for this purpose, capable of carrying out a wide range of littoral and coastal water law enforcement-naval duties and open sea rescue, including:

  • Patrol / Escort / Fast attack
  • Anti-piracy
  • Anti-terrorist protection of the coastal and offshore installations
  • Surveillance / Covert surveillance
  • Search and rescue
  • Anti-smuggling
  • Pollution control
General Data


ONUK MRTP34 Fast Patrol/Attack Craft is the 1m longer version of the proven ONUK MRTP 33. With 16 (sixteen) units of “Kaan 33” class ONUK MRTP 33 craft operational in the Turkish Coast Guard and foreign customers, the ONUK MRTP34 has a strong pedigree and very substantial improvements. .

ONUK MRTP34 has improved sea keeping, highly stealthy characteristics and is able to carry larger mission equipment/payload such as a 40 mm stabilized gun, surface-to-surface medium range missiles, EO sensors, fire control systems and decoys.


Speed and seakeeping:

The ONUK MRTP34 has been developed for a tough professional use with excellent performance qualities at both low and high speeds with strong emphasis on sea keeping. The ONUK OE-01 deep V hull, depending on engine selection and boat configuration, will enable the boat to reach speeds over 50 knots in calm waters and up to 30 knots in sea state 4. The ONUK MRTP34 has a soft and dry ride in adverse weather conditions, offering, thus, an outstanding platform capable of carrying state-of-the-art weapons and systems for the various tasks in the brown waters as well as the open sea.

The MJP water jet drive system, besides it’s extremely robust all stainless steel construction and very high efficiency, provides extreme manoeuvrability with high precision control and a very shallow draught, enhancing the operation in confined waters or intercepting/boarding larger ships in rough seas.

Stability: Intact-Damaged:

Naval standards have been applied to the ONUK MRTP34 for the intact and damaged stability. ONUK MRTP34 meets the Turkish Navy, NATO and DNV criteria for damaged stability and will remain afloat and upright with flooding in any single main compartment.


ONUK MRTP34 is built in advanced composites to satisfy the very tough requirements of an intensive professional use together with a long service life. The benefits of the advanced composite structure are:


  • Improved Performance
  • Increased Payload
  • Fuel savings


  • Longer service life
  • Maintenance savings


  • Threat avoidance / detection
  • Ballistic protection


  • Machinery vibration / acoustic
  • Magnetic signature
  • Heat signature

The hull and superstructure are constructed to Det Norske Veritas (DNV) HSLC classification and Naval Craft rules, and, will have DNV 1A1 HSLC Patrol R2 class notation. All boats of the series are and will be delivered with this class certificate.

The helm station and the interiors have been designed in line with the SAE recommendations for ergonomics to provide the crew with maximum comfort and minimum fatigue in prolonged use in heavy seas.

Machinery and propulsion
The CODAG high-speed propulsion system consists of two MTU 16V2000M90 diesels and a Honeywell TF50 gas turbine; all driving through MJP water jets. The diesels will allow 28 knots patrol speed, while the gas turbine will enable the boat to reach it’s maximum speed. CODOG and all diesel propulsion systems are available on request. Depending on the mission and speed requirements, the ONUK MRTP®33 can be equipped with different components for optimum operational efficiency/price ratio.

The mechanical components are selected with the intensive professional use in mind. They offer a high level of reliability, despite the extreme performance requirements.


ONUK MRTP34 can be equipped with various mission modules depending on the customer requirements. Despite the size of the platform, these modules have been integrated with the modularity and reconfigurability objectives in mind. Thus, the platform can be reconfigured with different mission modules, increasing dramatically the operational flexibility and reducing the costs.

The mission modules would be :

  • Multi weapon mounts.
    • Forward gun: BEA Bofors 40mm Mk or ASELSAN STOP stabilized turret with 25/30mm gun.
    • Medium range SSM (Harpoon Block II or equivalent).
    • Short range SAM.
    • 2x ASELSAN STAMP stabilized turret with 12,7mm MG.
  • Multi sensor surveillance suite
    • 2D Radar
    • EOD
  • Search and rescue equipment
  • Decoys
  • SOF (Special Operation Force) support/SDV (Seal team Delivery Vehicle)
  • Pollution control
