Submarine Development Program
The Submarine Development Program (PROSUB) is a partnership signed between Brazil and France in 2008, with the objective of Technology transfer, transferring technology for the Manufacturing, manufacture of military vessels. It is a component of the Brazil's Defense Strategy to develop the country's naval power with the production of four conventional submarines (diesel-electric propulsion) and the first Brazilian Nuclear submarine, nuclear-powered submarine. The program will make Brazil one of the few countries to have Nuclear power, nuclear technology, alongside the United States, Russia, France, the United Kingdom, China, and India. Although the program began in 2008 with the goal of providing the Brazilian Navy with a "large naval force," it dates back to the 1970s when the Navy began seeking to master nuclear energy. In order to shorten the development time of such a program, Brazil sought partners in other countries in the hope of establishing a partnership in which technolo ...

Axis Powers
The Axis powers, ; it, Potenze dell'Asse ; ja, 枢軸国 ''Sūjikukoku'', group=nb originally called the Rome–Berlin Axis, was a military coalition that initiated World War II and fought against the Allies. Its principal members were Nazi Germany, the Kingdom of Italy, and the Empire of Japan. The Axis were united in their opposition to the Allies, but otherwise lacked comparable coordination and ideological cohesion. The Axis grew out of successive diplomatic efforts by Germany, Italy, and Japan to secure their own specific expansionist interests in the mid-1930s. The first step was the protocol signed by Germany and Italy in October 1936, after which Italian leader Benito Mussolini declared that all other European countries would thereafter rotate on the Rome–Berlin axis, thus creating the term "Axis". The following November saw the ratification of the Anti-Comintern Pact, an anti-communist treaty between Germany and Japan; Italy joined the Pact in 1937, follow ...

Oberon-class Submarine
The ''Oberon'' class was a ship class of 27 British-designed submarines operated by five different nations. They were designed as a direct follow-on from the ''Porpoise'' class: physical dimensions were the same, but stronger materials were used in hull construction, and updated equipment was fitted. The submarines were built between 1957 and 1978 by four shipyards: Cammell Laird (4), Chatham Dockyard (6), Scotts Shipbuilding and Engineering Company (11) and Vickers-Armstrongs (6). Thirteen of the submarines were operated by the Royal Navy, six by the Royal Australian Navy, three by the Brazilian Navy, three by the Royal Canadian Navy/Canadian Forces Maritime Command (plus two ex-Royal Navy boats later acquired for non-commissioned roles), and two by the Chilean Navy. The ''Oberon''s operated during the height of the Cold War, with duties including surveillance, tracking of other ships and submarines, delivery and retrieval of special forces personnel, and serving as targets f ...

Greater Underwater Propulsion Power Program
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 navy began the program by testing and reverse engineering two German Type XXI U-boats— and —obtained as war reparation. That analysis led to four goals—increasing the submarines' battery capacity, streamlining the boats' structures, adding snorkels, and improving fire control systems. The navy immediately focused on designing a new class of submarine, but the Bureau of Ships believed the fleet of existing , , and submarines could be modified to incorporate the desired improvements. In June 1946, the Chief of Naval Operations approved the GUPPY project. The initial two-boat test program, implemented by the Portsmouth Naval Shipyard, eventually grew into several successive conversion programs. Those upgrades proceeded ...
