Air force

An air force, also known in some countries as an air army, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy, or a marine corps. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions, and providing support to land and naval forces.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation either within a national air force or comprising several air components from allied nations. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.

Many air forces are also responsible for operations of the military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as anti-aircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have an air defence force which is organizationally separate from their air force.

The United States of America (USA), commonly referred to as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major territories and various possessions. The 48 contiguous states and Washington, D.C., are in central North America between Canada and Mexico. The state of Alaska is in the northwestern part of North America and the state of Hawaii is an archipelago in the mid-Pacific. The territories are scattered about the Pacific Ocean and the Caribbean Sea. At 3.8 million square miles (9.842 million km²) and with over 320 million people, the country is the world's third or fourth-largest by total area and the third most populous. It is one of the world's most ethnically diverse and multicultural nations, the product of large-scale immigration from many countries. The geography and climate of the United States are also extremely diverse, and the country is home to a wide variety of wildlife.

The U (film)

The U is a 2009 documentary film about the University of Miami football program. It was produced by Miami-based media studio Rakontur and directed by Billy Corben.

The film premiered December 12, 2009 after the Heisman Trophy presentation on ESPN as a part of their 30 for 30 documentary series. The U's premiere drew 2.3 million viewers, the most ever for a documentary on the sports cable network until the debut of Pony Excess, another college football documentary about the Southern Methodist University football scandal in the 1980s.

DVD release

This film was released on DVD in 2010, both separately and as part of the 30 for 30 box set. The DVD cover, depicting Michael Irvin, originally had the "U" logo on his helmet, but it was airbrushed from the cover after the University of Miami objected to the logo's appearance. Excerpts from Florida State University's "Seminole Rap" video that initially appeared in the documentary were also cut from the DVD release.

Sequel

In December 2014, ESPN released a second 30 for 30, titled The U Part 2. The film documents the second rise to glory of the Miami Hurricanes football team in the late 1990s and early 2000s followed by the eventual fall of the program, due largely to a scandal in which multiple top players accepted cash rewards from booster, Nevin Shapiro.

United States Navy

The United States Navy (USN) is the naval warfare service branch of the United States Armed Forces and one of the seven uniformed services of the United States. The U.S. Navy is the largest, most capable navy in the world, with the highest combined battle fleet tonnage. The U.S. Navy has the world's largest aircraft carrier fleet, with ten in service, two in the reserve fleet, and three new carriers under construction. The service has 328,194 personnel on active duty and 101,199 in the Navy Reserve. It has 272 deployable combat vessels and more than 3,700 aircraft in active service as of February 2016.

The U.S. Navy traces its origins to the Continental Navy, which was established during the American Revolutionary War and was essentially disbanded as a separate entity shortly thereafter. It played a major role in the American Civil War by blockading the Confederacy and seizing control of its rivers. It played the central role in the World War II defeat of Japan. The 21st century U.S. Navy maintains a sizable global presence, deploying in such areas as East Asia, the Mediterranean, and the Middle East. It is a blue-water navy with the ability to project force onto the littoral regions of the world, engage in forward areas during peacetime, and rapidly respond to regional crises, making it an active player in U.S. foreign and defense policy.

Aircraft carrier

An aircraft carrier is a warship that serves as a seagoing airbase, equipped with a full-length flight deck and facilities for carrying, arming, deploying, and recovering aircraft. Typically, it is the capital ship of a fleet, as it allows a naval force to project air power worldwide without depending on local bases for staging aircraft operations. Aircraft carriers are expensive to build and are critical assets. Aircraft carriers have evolved from converted cruisers to nuclear-powered warships that carry numerous fighter planes, strike aircraft, helicopters, and other types of aircraft.

There is no single definition of an "aircraft carrier", and modern navies use several variants of the type. These variants are sometimes categorized as sub-types of aircraft carriers, and sometimes as distinct types of naval aviation-capable ships. Aircraft carriers may be classified according to the type of aircraft they carry and their operational assignments. Admiral Sir Mark Stanhope, former head of the Royal Navy, has said that "To put it simply, countries that aspire to strategic international influence have aircraft carriers".
