The Type 212A is a class of diesel-electric attack submarine developed by Howaldtswerke-Deutsche Werft AG (HDW) for the German Navy, and the Italian Navy where it is known as the Todaro class. It features diesel propulsion and an additional air-independent propulsion (AIP) system using Siemens proton-exchange membrane (PEM) compressed hydrogen fuel cells. The submarines can operate at high speed on diesel power or switch to the AIP system for silent slow cruising, staying submerged for up to three weeks with little exhaust heat. The system is also said to be vibration-free and virtually undetectable.
USS Tang (SS/AGSS-563), the lead ship of her class, was the second ship of the United States Navy to be named for the tang.
The Tang-class submarines were the first submarines designed and built by the United States Navy after World War II. They incorporated the best features of the high-speed German Type XXI U-boat and the venerable U.S. Navy fleet submarine. The Tang class, with the fleet submarines converted under the Greater Underwater Propulsion Power (GUPPY) program, had much higher submerged performance than their predecessors, but were quickly surpassed by the nuclear-propelled submarines that entered service beginning in 1954. Six units in total were built.
The Turkish Naval Forces, or Turkish Navy, is the naval warfare service branch of the Turkish Armed Forces.
USS Mapiro (SS-376), a Balao-class submarine, was a ship of the United States Navy named for the mapiro, a fish of the Gobioidea suborder occurring off the West Indies and the Atlantic coasts of Central America and Mexico.
Air-independent propulsion (AIP), or air-independent power, is any marine propulsion technology that allows a non-nuclear submarine to operate without access to atmospheric oxygen. AIP can augment or replace the diesel-electric propulsion system of non-nuclear vessels.
The Type 214 is a class of diesel–electric submarines developed exclusively for export by Howaldtswerke-Deutsche Werft GmbH (HDW). It features diesel propulsion with an air-independent propulsion (AIP) system using Siemens polymer electrolyte membrane (PEM) hydrogen fuel cells. The class combines the design principles of the Type 209 submarine family and the features of the Type 212A submarine. However, as an export design, it lacks some of the classified technologies of the Type 212 such as the non-magnetic steel hull that makes it difficult to detect using a magnetic anomaly detector.
The Ottoman Navy or The Imperial Navy, also known as the Ottoman Fleet, was the naval warfare arm of the Ottoman Empire. It was established after the Ottomans first reached the sea in 1323 by capturing Praenetos, the site of the first Ottoman naval shipyard and the nucleus of the future navy.
The Type 209 is a range of diesel-electric attack submarines developed exclusively for export by Howaldtswerke-Deutsche Werft of Germany. Five class variants, including modifications thereof, have been successfully exported to 15 countries, with 68 submarines being built and commissioned to five different variants between 1971 and 2021. More boats have been built to modified designs.
Aksaz Naval Base is a base of the Turkish Navy on the south-east coast of the Aegean Sea in Marmaris, Muğla. In addition to the military buildings, the base houses apartment-like barracks and social facilities stretched over 8,000 acres (32 km2) of land. Six helicopters are also stationed at Aksaz.
Gölcük Naval Shipyard is a naval shipyard of the Turkish Navy within the Gölcük Naval Base on the east coast of the Sea of Marmara in Gölcük, Kocaeli. Established in 1926, the shipyard serves for the building and the maintenance of military vessels. A total of 3,221 personnel are employed at the shipyard stretching over an area of 255,526 m2 (2,750,460 sq ft) with covered structures of 121,466 m2 (1,307,450 sq ft).
USNS Powhatan (T-ATF-166) was the lead ship of the United States Navy Powhatan-class fleet ocean tugboats. She was in service with the U.S. Navy from 1979 to 1999, and then was leased to a private towing and salvage company. At the end of the lease in 2008, the ship was sold to the Turkish Navy which recommissioned her as TCG Inebolu.
Sultanhisar was a torpedo boat of the Ottoman Navy. She was built in 1907 by Schneider & Cie in Chalon-sur-Saône, France, and transferred the same year to Turkey. She is best known for her action during the Gallipoli Campaign of World War I as she sank Royal Australian Navy submarine HMAS AE2 in the Sea of Marmara and captured her crew.
The Type 216 is a submarine design concept announced by the German shipbuilding company Howaldtswerke-Deutsche Werft based on the Type 212/214.
The Ada class is a class of anti-submarine corvettes developed primarily for the Turkish Navy during the first stage of the MILGEM project. The Turkish Navy has commissioned all four Ada-class corvettes.
TCG Anadolu (L-400) is an amphibious assault ship of the Turkish Navy. It is named after the peninsula of Anatolia which forms the majority of the land mass of Turkey. The construction works began on 30 April 2016 at the shipyard of Sedef Shipbuilding Inc. in Istanbul, with the keel being laid on 7 February 2018. TCG Anadolu was commissioned with a ceremony on 10 April 2023.
Atmaca (Accipiter) is an all weather, long range, precision strike, anti-ship cruise missile, developed by Turkish missile manufacturer Roketsan. The Atmaca enters service with the Turkish Navy to gradually replace the country's existing inventory of Harpoon missiles.
