TCG Anadolu (L-400)

TCG Anadolu Multi-Purpose Amphibious Assault Ship (LHD) is the world’s first armed unmanned aerial vehicle (UAV) carrier, designed for the Turkish Naval Forces Command. It is capable of integrating land, sea, and air elements to conduct amphibious operations, air operations, and humanitarian aid/disaster relief missions. The vessel can deploy military vehicles, helicopters, and unmanned aerial systems and possesses the ability to independently reach crisis and conflict zones, conduct beach landings, perform evacuations, and provide logistical support. It also features fully equipped hospital and operating room sections. TCG Anadolu is positioned as a national defense industry product with a high level of local content and equipped with modern avionics, weapons, and electronic warfare systems.

Development Process

Project Initiation

The TCG Anadolu project was launched in 2015 by the Presidency of Defense Industries (SSB) to meet the Turkish Naval Forces’ requirement for a Multi-Purpose Amphibious Assault Ship (LHD). The primary objective of the program is to introduce a strategic platform capable of force projection and amphibious operations in the Aegean, Mediterranean, and Black Seas without reliance on main base support.

The project was developed in collaboration between Sedef Shipyard and the Spanish company Navantia, inspired by the design of the Juan Carlos I ship in the Spanish Navy inventory. In addition to 131 subcontractors, universities and research centers also participated in this project.

Construction and Testing Phases

On 30 April 2016, the first steel cutting ceremony was held at Sedef Shipyard, officially commencing the ship’s construction. The construction process included block fabrication, assembly, and system integration. Between 2019 and 2022, the main hull assembly was completed and testing of the marine systems began.

On 7 March 2022, TCG Anadolu conducted its first sea acceptance and navigation trials (sea trials). These tests verified the performance of the ship’s propulsion, navigation, and basic systems. Throughout the construction phase, the flight deck and hangar were modified to accommodate rotary-wing and fixed-wing unmanned aerial systems (UAVs/UCAVs).

Commissioning and Operational Developments

Following the completion of sea and port acceptance tests, temporary acceptance of TCG Anadolu was granted on 21 January 2023. Its official entry into the Turkish Naval Forces inventory and commissioning took place on 10 April 2023. TCG Anadolu serves as the flagship and largest displacement unit of the Turkish Navy.

Operationally, in addition to amphibious missions, it is used as a test and training platform for the integration of indigenous aircraft, particularly Bayraktar TB3 UAVs, and maritime-based operations. Its first major mission after entering service was participation as the flagship in the “Sea Wolf Exercise” exercise conducted in the Aegean and Mediterranean Seas in June 2023. During this exercise, the ship’s amphibious assault capabilities and command-and-control functions were operationally tested.

Technical Specifications

TCG Anadolu (L-400) is designed as the world’s first armed unmanned aerial vehicle (UAV) carrier in the Multi-Purpose Amphibious Assault Ship (LHD) class and holds the distinction of being Türkiye’s largest military vessel. Only 12 countries worldwide possess vessels of this scale. The ship has the capacity to transport a force of at least battalion size to crisis areas in the Aegean, Mediterranean, and Black Seas with its own logistical support, without requiring main base assistance.

The local content rate of the project is approximately 70%. All systems on board—including weapons, combat management, electronic warfare, and radar systems—have been developed domestically using national capabilities. Additionally, the fully equipped hospital and operating room facilities were designed for use in natural disaster relief operations.

TCG Anadolu has a length of 231 meters and a width of 32 meters. With a maximum displacement of 27,436 tons, the vessel can operate at a maximum speed of at least 20.5 knots and an economical speed of 16 knots.

Aircraft Capacity

TCG Anadolu is recognized as the world’s first UAV carrier due to its ability to launch and recover UAVs. For this role, Baykar has developed the Bayraktar TB3 UAV with foldable wings. Additionally, work is ongoing to enable the launch and recovery of Bayraktar Kızılelma and TUSAŞ’s Hürjet Light Attack Aircraft.

The flight deck can accommodate 10 helicopters or 11 UAVs, while the hangar can carry 19 helicopters or 30 UAVs.

Land Vehicle Capacity

The ship can carry a total of 94 vehicles on its vehicle decks. The breakdown is as follows: 13 tanks, 27 Armored Amphibious Assault Vehicles (ZAHA), 6 armored personnel carriers, 33 miscellaneous vehicles, and 15 trailers.

Deployed Air Systems

Aircraft Deployment and Carried Systems (Air Load)

Designed in accordance with the UAV carrier concept, TCG Anadolu provides the capability to deploy primary air platforms. The indigenous air systems targeted for deployment and under development on the ship include:

• Fixed-Wing UAVs/UCAVs: Baykar has developed the foldable-wing Bayraktar TB3 UAV. Integration efforts are ongoing to enable the launch and recovery of the Bayraktar Kızılelma combat UAV and the Hürjet Light Attack Aircraft developed by Turkish Aerospace Industries (TUSAŞ).
• Aircraft Capacity: The flight deck can accommodate 10 helicopters or 11 UAVs, while the hangar can carry 19 helicopters or 30 UAVs.

Self-Defense Systems and Electronic Warfare (Self-Defense / Security)

The ship is equipped with various indigenous and foreign-origin self-defense systems to protect itself against close-range air and surface threats.

• Close-In Weapon System (CIWS): The ship is armed with U.S.-made Phalanx Close-In Weapon Systems for defense against air and surface threats, and their firing tests have been successfully completed.
• Stabilized Weapon Systems: Five 25 mm STOP and four 12.7 mm STAMP weapon systems developed by ASELSAN fulfill the self-defense role.
• Combat Management and Electronic Warfare: The combat management system, electronic warfare systems, infrared search and track system, electro-optical search system, laser warning system, and torpedo defense system have all been developed using national capabilities. Communication systems were developed through a partnership between ASELSAN and HAVELSAN.

Command, Control, and Sensor Systems

Combat Management and Electronic Systems

The ship’s combat systems were developed through a partnership between ASELSAN and HAVELSAN. The platform has the capability to provide Command and Control (C2) and amphibious operation support.

• Data Links: TCG Anadolu can utilize NATO-compatible tactical data link systems including Link 11, Link 16, Link 22, and VMF.
• Reconnaissance and Tracking Systems: The ship incorporates electronic systems such as infrared search and track, electro-optical search, laser warning, and torpedo defense systems, all developed using national capabilities.

Radar and Navigation Systems

The ship’s radar and navigation systems have been created through the integration of indigenous and foreign components to ensure operational effectiveness and flight safety.

The radar suite on TCG Anadolu includes one 3D search radar, one air detection and control radar, and one precision approach radar. Additionally, two LPI radars and navigation radars are also installed.
