The Greater Underwater Propulsion Power Program (GUPPY) was initiated by the United States Navy after World War II to improve the submerged speed, maneuverability, and endurance of its submarines. (The "Y" in the acronym was added for pronounceability.)
The Tang-class submarines were the first submarines designed and built by the United States Navy after WWII. 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 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.
MILGEM project is a national warship program of the Republic of Turkey. Managed by the Turkish Navy, the project aims at developing multipurpose corvettes, frigates and destroyers that can be deployed in a range of missions, including reconnaissance, surveillance, early warning, anti-submarine warfare, surface-to-surface and surface-to-air warfare, and amphibious operations.
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.

The Type 216 is a submarine design concept announced by 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.
