THE 33 METRE Fast Patrol / Attack Craft
The advanced composite ONUK MRTP®33 Fast Patrol / Attack Craft is the extended and improved version of the 90 tonne ONUK MRTP®29 ("KAAN 29” Class) of the Turkish Coast Guard. ONUK MRTP®33 is developed as a versatile multi role platform for the increasingly tough requirements of the naval and law enforcement forces to control the littoral and the coastal waters.

Internally, the advanced machinery systems and arrangement result in a vessel with greatly enhanced operability, maintainability and accommodation standards.

PRIMARY ROLES
Mastery of the littoral can not 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 MRTP®33 "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
Search and rescue
Anti smuggling
Pollution control
Anti terrorist protection of the coastal and offshore installations
Surveillance / Covert surveillance
Seal insertion-extraction

BACKGROUND:
As of January 2004, 9 units of the "KAAN 29" Class boats (31,70m, 45+ knots) under DNV classification (HSLC Patrol R2) are operational. Boat number 10 of 90 tonne was constructed as the first ONUK MRTP®33 (35,60m, 120 tonne, 47+ knots) as continuation of the project others are under construction at the shipyard.

The new member of the MRTP® (Multi Role Tactical Platform) family of boats, a concept created and developed by Kaan N.Z. Onuk; has improved sea keeping, highly stealthy characteristics, and is able to carry larger mission equipment/payload such as combined 30mm gun and short range SSM stabilized launcher, surface-to-surface medium range F&F fiber guided missiles, EO fire control systems and decoys.

PERFORMANCE:
Speed and seakeeping:
The ONUK MRTP®33 has been developed for a tough professional use with excellent performance qualities at both low and high speeds and strong emphasis on seakeeping. The ONUK OE-01 deep V hull, depending on engine selection and boat configuration, will enable the boat to reach speeds up to 64 knots in calm waters and up to 40 knots in Sea State 4. ONUK MRTP®33 has a soft and dry ride in adverse conditions, offering, thus, an outstanding platform for the various tasks in the brown waters and the open sea.

The MJP water jet drive system provides extreme maneuverability 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:
Commercial and Turkish / NATO naval standards have been applied to the ONUK MRTP®33 for the intact and damaged stability. ONUK MRTP®33 meets the DNV standards as well as Turkish Navy and NATO criteria for damaged stability and will remain afloat and upright with flooding in any single main compartment.

CONSTRUCTION AND COMPONENTS:
ONUK MRTP®33 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:

WEIGHT REDUCTION
* Improved Performance
* Increased Payload
* Fuel Savings

CORROSION RESISTANCE
*Longer service life
* Maintenance savings

IMPROVED
* Threat avoidance/detection
* Ballistic protection

REDUCED SIGNATURES
* Machinery vibration/acoustic
* Magnetic signature
* Heat signature

The hull and superstructure are constructed to Det Norske Veritas (DNV) HSLC Patrol R2 classification. All boats of the series are delivered with the relevant DNV Certificates.

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.

MISSION MODULES
ONUK MRTP®33 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.
- Stabilized naval turret with up to 30 mm. gun
(+ short range SSM).
- Medium range SSM (Total weights up to 5 tons).
- Short range SAM.
- 2 x 12.7 mm. heavy MG.
Multi sensor surveillance unit
(EOD with capabilty of controlling the main gun).
Search and rescue equipment
Decoys
SOF (Special Operation Forces) support/SDV (Seal Delivery Vehicle)
Pollution control

Dreadnought

Nice boat. Looks very much like the Litorial Combat Ship by Lockheed Martin.

but this is not a concept, it is in service now.

if Lockheed's is in service too (i dont know ) i hope the similarity is just a coincidence

Dreadnought

Im not sure but I believe one was launched not long ago the LCS Freedom.

and the same base is


S36
After the very successful “Kaan29” class ONUK MRTP29® (31,70m, 50 knots) and the “Kaan33” class ONUK MRTP33® (35,80m, 48 knots) of the Turkish Coast Guard, Yonca-Onuk JV decided to apply the advancements and technology of the MRTP® program to a family of high-speed luxury motor yachts:


The YONtech S line.
Intended to be the symbol of excellence and perfection, the “YONtech S36” (35,80 m) based on the ONUK MRTP33® hull and technology, is a radical machine capable of speeds in excess of 65 knots, accommodating 8 guests in extreme luxury and styling.

The ONUK MRTP33®'s strong heritage is the source of “mission proven” excellent dynamic characteristics of the YONtech S36 at both low and high speeds. The outstanding seakeeping of YONtech S36 will ensure high standards of comfort, performance and reliability, even in adverse sea conditions.

In the struggle to provide these striking performances with very high levels of safety and reliability, YONtech S class yachts are to built to DNV HSLC R2 classification rules as the ONUK MRTP® patrol boats.

YONtech S36 features advanced composites DNV classified structure, all diesel or CODAG or CODOG power driving through waterjets. The styling reflects the heritage of the IDSA (Industrial Designers Society of America) Industrial Design Excellence Award medal winning M/Y Motali.

Dreadnought

Nice.

Big K

hımm but it's bigger than mrtp-33? i think this is a corvette or a frigate?

Dreadnought

Yes it is bigger in order to support fast helo ops as well as other missions. I would think it would be closer to a corvette then a frigate. I havent looked at what the specs are based upon for the LCS.

Big K

than this a ship not a boat

Dreadnought

Thats a big "grey" area. Since I serve aboard a ship almost 900 feet in length and many a gentlemen hear have served bigger and smaller vessels that would constitute a good question. Where does the term "boat" become "ship"?

Big K

maybe we can compare "boat" and "ship" with their "turning radius"??

i mean maneuvrability?,

for exemple a smaller boat can beat a bigger ship with the same firepower?

mobility is an advantage, isnt it?

Dreadnought

Absolutely. Mobility is quite an advantage when one is in the open. Larger ships need speed in order to manuver better. As when they slow they become alot less responsive to the helm. Smaller boats can "heel" into turns much faster because the distance from the hull to hard over keel (the point at which the hull rides when turning) is much shorter. The distance or draft between the tumblehome of a ship and the heel effect is much greater so it is a much larger turning radi then the smaller ship or boat.

The design of the two ships used for comparison also matters greatly.

is there any "Katamaran" bodied war ship or boat?
