Yonca-Onuk, one of the pioneering companies of the Turkish defence industry in the maritime field, is completely changing the rules of the game in coastal waters and the open seas with its developed MRTP (Multi-Role Tactical Platform) family. Designed for forces aiming to dominate the seas in the 21st century, these platforms stand out with their advanced composite materials, immense speed, and high firepower. Successfully serving in world navies, particularly the Turkish Coast Guard Command, these craft offer unique deterrence against asymmetric threats.
Three Core Principles: Speed, Survivability, and Stealth
Yonca-Onuk engineers have built the design philosophy of the MRTP series on three fundamental elements (3S): Speed, Seakeeping, and Stealth. To achieve these goals, the company extensively uses advanced composite technologies in hull construction.
The composite structure significantly reduces the weight of the platforms. This weight reduction directly increases fuel efficiency, operational range, and weapon-carrying capacity. Furthermore, this special material prevents corrosion caused by seawater, extending the platform's service life. Most importantly, the composite hull minimises the craft's acoustic, infrared, and radar cross-section (RCS), making the platform virtually invisible to enemy radars.
The MRTP Family: Classes and Technical Specifications
Shaped according to the demanding operational needs of naval forces and law enforcement agencies, the MRTP family is divided into different classes based on size and mission profiles.
MRTP-15 (Kaan 15 Class): The Swift Hunter of Shallow Waters
The first member of the MRTP family, the MRTP-15, was specifically developed to control coastal waters. In narrow areas and heavy weather conditions where helicopters cannot operate, it can react as quickly as a helicopter. Proven in the field since 1997, the platform minimises crew fatigue with its ergonomic design.
- Speed Performance: Over 70 knots (approx. 130 km/h) in Sea State 2; over 50 knots in Sea State 3.
- Payload Capacity: Over 1.5 tonnes of mission and weapon load.
- Drive System: Twin MTU diesel engines. Propulsion is provided by Arneson surface drives or MJP waterjets.
- Mission Profile: Search and rescue, anti-smuggling, facility protection, and special forces (SEAL) infiltration/exfiltration operations.
MRTP-29 (Kaan 29 Class): The 90-Tonne Offshore Guardian
A 90-tonne fast patrol craft with significantly enhanced offshore capabilities. The hull design utilises the combat-proven deep V (OE01) form. It complies fully with international DNV (Det Norske Veritas) rules as well as NATO and Turkish Naval Forces standards.
- Speed Performance: Operational speed exceeding 35 knots in all directions. (It proved its mettle by reaching 68 knots during tank tests in Sea State 4).
- Endurance: Excellent manoeuvrability and seakeeping capability at both low and high speeds.
- Mission Profile: Escort, assault, and covert surveillance in heavy sea conditions.
MRTP-33: Heavy Assault Power in Hostile Waters
This is the "Extended Assault" version of the MRTP-29, capable of carrying more weapon load and featuring enhanced seakeeping qualities. Designed for navies seeking absolute superiority in coastal waters, this platform houses immense firepower relative to its size.
- Speed Performance: Speed exceeding 45 knots in Sea State 4.
- Drive System: Alongside diesel-only options, a CODAG (Combined Diesel and Gas Turbine) and MJP waterjet configuration for increased operational flexibility.
- Heavy Armament: 30 mm stabilised naval gun mounts, short-range air defence and surface-to-surface missiles. Furthermore, the craft is designed to carry a battery of 4 medium-range anti-ship missiles. This feature transforms it into a highly formidable platform in naval warfare.
From Military Technology to the Civilian Sector: The Yontech S Series
Yonca-Onuk does not confine its unique aerodynamic and composite expertise gained in the military field solely to the defence industry. The company successfully transfers this technology to its high-performance luxury yacht series, the "Yontech S" line.
For example, the Yontech S21, based on MRTP-20 hull technology, reaches incredible speeds of over 75 knots with standard MTU diesel engines. The flagship of the series, the Yontech S36, uses the MRTP-33 hull architecture. This massive machine can accommodate 8 guests in extremely luxurious conditions while traveling at speeds exceeding 68 knots.
Future Vision
Yonca-Onuk, with its composite material technology and innovative propulsion systems, is taking Türkiye's operational speed at sea far beyond global standards. The company continues to push engineering boundaries by extending this dynamic knowledge in shipbuilding to sports car designs. Unmanned marine vehicle algorithms to be integrated into these super-fast platforms in the future will elevate the export potential of the MRTP family in the global market to its peak.
