The Steadfast Dart 26 exercise taking place in Germany marks the first major test for NATO’s rapid reaction forces – the Allied Reaction Force (ARF). From mid-January through March, units assigned to the ARF will move to training areas located in Germany, where simulated combat operations will be conducted. More than 10,000 troops from 11 countries are taking part, employing over 1,500 vehicles and nearly 20 naval vessels. Turkey has deployed a substantial contingent consisting of four warships and nearly 2,000 troops.
The Turkish–Spanish Armada in Germany
One of the key components of the Steadfast Dart 26 exercise is the participation of a joint Spanish–Turkish naval task group. It includes:ESPS Castilla (L52),
- ESPS Cristobal Colon (F 105),
- TCG Anadolu (L 400),
- TCG İstanbul (F 515),
- TCG Oruçreis (F 245),
- TCG Derya (A 1590).
Turkish units arrived at the port of Rota in late January and, together with Spanish vessels, subsequently sailed for Germany. Some of the Turkish vehicles, including BMC Vuran armored personnel carriers, were unloaded on February 8 at the port of Emden. The ships then proceeded to Kiel, where they remained from February 11 to 13. On February 18, an amphibious landing was conducted at the Putlos training area in northern Germany, with TCG Anadolu and ESPS Castilla playing leading roles. The amphibious task group was supported by vessels from Standing NATO Maritime Group 1 (SNMG1) and Standing NATO Mine Countermeasures Group 1 (SNMCMG1). Since January 2026, ORP Kontradmirał Xawery Czernicki has been leading the mine countermeasures group. The presence of the Polish vessel within SNMCMG1 marked Poland’s only contribution to Steadfast Dart 26.

TCG Anadolu is the largest and most advanced vessel in the Turkish Navy (Türk Deniz Kuvvetleri). The design was developed on the basis of the proven Navantia Athlas 26000 project, which had previously served as the template for the Spanish amphibious assault ship Juan Carlos I as well as the Australian vessels HMAS Canberra and HMAS Adelaide.
Construction of TCG Anadolu began in 2018, and the ship was commissioned in 2023. All work was carried out in Turkish shipyards, with most of the armament and equipment supplied by domestic defense industry companies. Since the mid-1990s, Turkey has consistently invested in achieving the highest possible level of defense self-sufficiency. Anadolu stands as a clear example of that strategic independence.
A Ski-Jump Launch Ramp for Unmanned Aerial Vehicles
TCG Anadolu is 232 meters long and can reach a maximum speed of 21 knots. The crew consists of 371 officers and sailors, with capacity to embark up to 900 marines, as well as hospital personnel and crews assigned to helicopters and unmanned aerial vehicles.
The ship can carry in its well deck and vehicle storage area:
- 4 LCM-1E landing craft, or alternatively 2 LCAC hovercraft;
- 8 LCVP landing craft;
- 27 ZAHA tracked amphibious armored vehicles.

Beneath the flight deck, there is a hangar capable of accommodating up to 12 Sikorsky S-70 (T-70/S-70B) helicopters or up to 8 Boeing CH-47 Chinook helicopters. The flight deck itself can host 6 helicopters, with space for an additional 13 aircraft on the vehicle deck. Due to political tensions with the United States, Turkey was unable to procure the Lockheed Martin F-35B Lightning II. Instead, the ship has been adapted to operate Turkish-produced unmanned aerial vehicles, including the Bayraktar TB3 and, in the future, the jet-powered Bayraktar Kızılelma. The ship can also operate Bell AH-1W Super Cobra and T129 ATAK attack helicopters. In addition, the vessel is capable of transporting 28 main battle tanks and dozens of other wheeled or tracked vehicles.

The ship’s armament is purely defensive and consists of:
- two 20 mm Phalanx CIWS Mk 15 Phalanx Block 1 close-in weapon systems;
- five 25 mm Aselsan STOP remote-controlled weapon systems;
- five 12.7 mm Aselsan STAMP stabilized weapon platforms;
- the Izir torpedo countermeasure system.
TCG Anadolu is also equipped with numerous sensors, including the SMART-S Mk2 radar, the Aselsan ARES electronic warfare system, and the Havelsan GENESIS ADVENT combat management system.

TCG İstanbul
TCG İstanbul (F-515) is the lead ship of the İstanbul-class (also known as the Istif-class) frigates. It represents another key component of Turkey’s ambitious MILGEM (Milli Gemi – “National Ship”) program, aimed at independently designing and building warships for the Turkish Navy. İstanbul is a frigate developed on the basis of the earlier Ada-class corvette design. Construction began in 2017, and the ship was commissioned in 2024.
TCG İstanbul
TCG İstanbul (F-515) is 113.2 meters long and can reach a maximum speed of 29 knots. The crew consists of 123 officers and sailors.
Its armament includes:
- a single OTO Melara 76 mm Super Rapid naval gun (optionally the MKE 76 mm/62);
- one twin-barrel 35 mm Aselsan GOKDENIZ close-in weapon system;
- two 25 mm Aselsan STOP remote-controlled weapon stations;
- a MIDLAS VLS vertical launch system with 16 HISAR-D surface-to-air missiles;
- 16 Atmaca anti-ship missiles;
- two twin 324 mm torpedo launchers;
- 7.62 mm MG3 machine guns.

Additional equipment includes a single Sikorsky SH-60B Seahawk helicopter for anti-submarine warfare (ASW) operations.
The ship is equipped with the SMART-L long-range surveillance radar and the APAR radar system, whose primary role is the detection of airborne and surface targets during NATO naval task group escort operations.
The primary gun is the OTO Melara 76 mm Super Rapid. Starting with the second ship of the class, the Turkish-made MKE 76 mm/62 is to be installed on the bow instead.
TCG İstanbul (F-515) is equipped with numerous sensors, including the Aselsan CENK-S three-dimensional radar, the Aselsan ARES electronic warfare system, and the Havelsan GENESIS ADVENT combat management system.
Work is currently underway on five additional İstanbul-class frigates, and there are plans to procure two more ships to replace the older Yavuz-class frigate vessels.

TCG Derya
TCG Derya is a logistics support vessel whose construction began in 2018 and which entered service in early 2024.
TCG Derya
The objective was to create a versatile vessel capable of:
- transporting aviation fuel, marine fuel, or fresh water;
- supplying other ships using the RAS (Replenishment At Sea) system;
- operating as a command ship for a naval task group or amphibious force;
- conducting maritime operations using unmanned systems.


TCG Derya is 194.8 meters long and can reach a maximum speed of 28 knots. The crew consists of 326 officers and sailors.
Its armament includes:
- two twin-barrel 35 mm Aselsan GOKDENIZ systems;
- two 25 mm Aselsan STOP remote-controlled weapon stations.
In addition, the hangar can accommodate two helicopters, enabling the ship to resupply other vessels by air.

On the stern of TCG Derya, a twin-barrel 35 mm Aselsan GOKDENIZ gun system has been installed, along with two 25 mm Aselsan STOP remote-controlled weapon stations

Summary
The Steadfast Dart 26 exercise demonstrated how crucial amphibious assault ships, protected by frigates, are to modern warfare. It was precisely around TCG Anadolu and ESPS Castilla that amphibious forces conducted a simulated assault at the Putlos training area in northern Germany. Thanks to the capabilities of European navies, U.S. vessels were effectively replaced by ships from Turkey and Spain.
Between 2022 and 2024, U.S. Navy amphibious ships regularly participated in exercises in Europe. In 2025, however, the United States did not schedule a vessel of this type to take part in the annual BALTOPS maneuvers. This led to the decision to deploy amphibious assault ships to Germany for Steadfast Dart instead. It is worth noting that specialized amphibious ships are also operated by France, Italy, the Netherlands, and the United Kingdom.
Turkey used the European exercise to test its ships under the harsh winter conditions of northern Europe. TCG Anadolu, TCG İstanbul (F-515), and TCG Derya are relatively new vessels, and their participation in Steadfast Dart provided an ideal opportunity for long-duration crew training and for validating technical and tactical assumptions.
From Anadolu’s deck, an autonomous mission of a Bayraktar TB3 unmanned aerial vehicle was conducted, employing Roketsan MAM-L precision-guided munitions against a surface target. This demonstrated that Turkey has successfully adapted its amphibious assault ship to operate unmanned aircraft in place of the previously planned Lockheed Martin F-35B Lightning II.
For Turkey, the presence of its most advanced vessels also provided an opportunity to showcase achievements in warship construction, unmanned systems, and wheeled and tracked vehicles. It also sent an important signal to European allies that, in the event of a potential conflict, the Alliance’s second-largest military is capable of providing support. NATO was also able to test the rapid redeployment of forces from southern to northern Europe using all available means of transport.
