Portuguese NavyThe Portuguese Navy (Marinha Portuguesa, also known as Marinha de Guerra Portuguesa or as Armada Portuguesa) is the naval branch of the Portuguese Armed Forces which, in cooperation and integrated with the other branches of the Portuguese military, is charged with the military defense of Portugal. On 12 December 2017, the Portuguese Navy commemorated the 700th anniversary of its official creation by King Denis of Portugal. Tracing its origins back to the 12th century, it is the oldest continuously serving navy in the world.
Airborne early warning and controlAn airborne early warning and control (AEW&C) system is an airborne radar system designed to detect aircraft, ships, vehicles, missiles, and other incoming projectiles at long ranges and perform command and control of the battlespace in an air engagement by directing fighter and attack aircraft strikes. AEW&C units are also used to carry out surveillance, including over ground targets and frequently perform battle management command and control (BMC2).
Indian Air ForceThe Indian Air Force (IAF) is the air arm of the Indian Armed Forces. Its primary mission is to secure Indian airspace and to conduct aerial warfare during armed conflicts. It was officially established on 8 October 1932 as an auxiliary air force of the British Empire which honoured India's aviation service during World War II with the prefix Royal. After India gained independence from United Kingdom in 1947, the name Royal Indian Air Force was kept and served in the name of the Dominion of India.
United States NavyThe United States Navy (USN) is the maritime service branch of the United States Armed Forces and one of the eight uniformed services of the United States. It is the largest and most powerful navy in the world, with the estimated tonnage of its active battle fleet alone exceeding the next 13 navies combined, including 11 allies or partner nations of the United States as of 2012. It has the highest combined battle fleet tonnage (4,635,628 tonnes as of 2019) and the world's largest aircraft carrier fleet, with eleven in service, two new carriers under construction, and five other carriers planned.
ISROThe Indian Space Research Organisation, commonly referred to as ISRO (ˈɪsroʊ), is the national space agency of India. It operates under the Department of Space (DOS) which is directly overseen by the Prime Minister of India, while the Chairman of ISRO also acts as the executive of DOS. ISRO is primarily responsible for performing tasks related to space-based applications, space exploration, international space cooperation and the development of related technologies.
Nuclear marine propulsionNuclear marine propulsion is propulsion of a ship or submarine with heat provided by a nuclear reactor. The power plant heats water to produce steam for a turbine used to turn the ship's propeller through a gearbox or through an electric generator and motor. Nuclear propulsion is used primarily within naval warships such as nuclear submarines and supercarriers. A small number of experimental civil nuclear ships have been built. Compared to oil- or coal-fuelled ships, nuclear propulsion offers the advantage of very long intervals of operation before refueling.
CorvetteA corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper (or "rated") warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern roles that a corvette fulfills include coastal patrol craft, missile boat and fast attack craft. These corvettes are typically between 500 and 2,000 tons. Recent designs of corvettes may approach 3,000 tons and include a hangar to accommodate a helicopter, having size and capabilities that overlap with smaller frigates.
Blue-water navyA blue-water navy is a maritime force capable of operating globally, essentially across the deep waters of open oceans. While definitions of what actually constitutes such a force vary, there is a requirement for the ability to exercise sea control at long range. The term "blue-water navy" is a maritime geographical term in contrast with "brown-water navy" (river and near to shore) and "green-water navy" (near to shore).
Japan Maritime Self-Defense Force, abbreviated JMSDF, also simply known as the Japanese Navy, is the maritime warfare branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. The JMSDF was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships, 346 aircraft and 50,800 personnel. Safety Security Force Following Japan's defeat in World War II, the Imperial Japanese Navy was dissolved by the Potsdam Declaration acceptance.
Naval gunfire supportNaval gunfire support (NGFS), also known as naval surface fire support (NSFS), or shore bombardment, is the use of naval artillery to provide fire support for amphibious assault and other troops operating within their range. NGFS is one of several disciplines encompassed by the term naval fires. Modern naval gunfire support is one of the three main components of amphibious warfare assault operations support, along with aircraft and ship-launched land-attack missiles.
