Except in a few instances, since World War II no American soldier or sailor has been attacked by enemy air power. Conversely, no enemy soldier orsailor has acted in combat without being attacked or at least threatened by American air power. Aviators have brought the air weapon to bear against enemies while denying them the same prerogative. This is the legacy of the U.S. AirForce, purchased at great cost in both human and material resources.More often than not, aerial pioneers had to fight technological ignorance, bureaucratic opposition, public apathy, and disagreement over purpose.Every step in the evolution of air power led into new and untrodden territory, driven by humanitarian impulses; by the search for higher, faster, and farther flight; or by the conviction that the air way was the best way. Warriors have always coveted the high ground. If technology permitted them to reach it, men, women andan air force held and exploited it-from Thomas Selfridge, first among so many who gave that "last full measure of devotion"; to Women's Airforce Service Pilot Ann Baumgartner, who broke social barriers to become the first Americanwoman to pilot a jet; to Benjamin Davis, who broke racial barriers to become the first African American to command a flying group; to Chuck Yeager, a one-time non-commissioned flight officer who was the first to exceed the speed of sound; to John Levitow, who earned the Medal of Honor by throwing himself over a live flare to save his gunship crew; to John Warden, who began a revolution in air power thought and strategy that was put to spectacular use in the Gulf War.Industrialization has brought total war and air power has brought the means to overfly an enemy's defenses and attack its sources of power directly. Americans have perceived air power from the start as a more efficient means of waging war and as a symbol of the nation's commitment to technology to master challenges, minimize casualties, and defeat adversaries.

Annually, CSIS senior adviser Mark Cancian publishes a series of papers on U.S. military forces—their composition, new initiatives, long-term trends, and challenges. The overall theme of this year’s report is the struggle to align forces and strategy because of budget tradeoffs that even defense buildups must make, unrelenting operational demands that stress forces and prevent force structure reductions, and legacy programs whose smooth operations and strong constituencies inhibit rapid change. This report takes a deeper look at the strategic and budget context, the military services, special operations forces, DOD civilians and contractors, and non-DOD national security organizations in the FY 2020 budget.

CSIS senior adviser Mark Cancian annually produces a series of white papers on U.S. military forces, including their composition, new initiatives, long-term trends, and challenges. This report is a compilation of these papers and takes a deep look at each of the military services, the new Space Force, special operations forces, DOD civilians, and contractors in the FY 2021 budget. This report further includes a foreword regarding how the Biden administration might approach decisions facing the military forces, drawing on insights from the individual chapters.

When the United States Army Signal Corps created the Aeronautical Division in August1907, it had a mission to take charge of all matters pertaining to military ballooning,air machines, and all kindred matters. That small inconsequential portion of the USArmy would grow progressively over the many decades to become a separate service named the USAir Force in 1947 following the Second World War. Overnight, it became the worlds most powerfulmilitary establishment, able to deliver conventional and nuclear ordnance anywhere around theglobe.Todays cutting-edge example of this power-projection is the supersonic, bat-winged B-2 Spiritstealth bomber, which can fly at an altitude of 50,000 feet, and is built of carbon-graphite compositematerials. The B-2 Spirit is a far cry from the early days of the service when it relied on fragile prop-drivenwood and fabric aerial platforms, such as the Wright Type B, which could barely reach analtitude of 100 feet.In between have been such iconic Second World War aircraft as the P-51 Mustang and P-47Thunderbolt fighters and bombers such as the B-25 Mitchell, B-17 Flying Fortress and B-29 SuperFortress which dropped the first A-Bomb in 1945. The Cold War demanded ever more powerfulaircraft, such as the B-58 Hustler and B-52 Stratofortress, and fighters including the F-86 Sabre, F-104Starfighter and F-4 Phantom. All these aircraft and more are vividly illustrated and described in detailin this superb Images of War publication.

In February 1999, only a few weeks before the U.S. Air Force spearheaded NATO's Allied Force air campaign against Serbia, Col. C.R. Anderegg, USAF (Ret.), visited the commander of the U.S. Air Forces in Europe. Colonel Anderegg had known Gen. John Jumper since they had served together as jet forward air controllers in Southeast Asia nearly thirty years earlier. From the vantage point of 1999, they looked back to the day in February 1970, when they first controlled a laser-guided bomb strike. In this book Anderegg takes us from "glimmers of hope" like that one through other major improvements in the Air Force that came between the Vietnam War and the Gulf War. Always central in Anderegg's account of those changes are the people who made them. This is a very personal book by an officer who participated in the transformation he describes so vividly. Much of his story revolves around the Fighter Weapons School at Nellis Air Force Base (AFB), Nevada, where he served two tours as an instructor pilot specializing in guided munitions.

The P-47 Thunderbolt, originally designed as a high-altitude interceptor, became the principal US fighter–bomber of World War II. First adapted to the ground attack role by units of the Twelfth Air Force in early 1944, the strength and durability of the P-47 airframe, along with its massive size, earned it the nickname 'Juggernaut', which was quickly shortened to 'Jug' throughout the MTO and ETO. By October 1943, with the creation of the Fifteenth Air Force, nearly half of the Twelfth's fighter groups would be retasked with strategic escort missions, leaving six groups to perform close air support and interdiction missions throughout the entire Mediterranean theatre. The groups inflicted incredible damage on the enemy's transport routes in particular, using rockets, bombs, napalm and machine-gun rounds to down bridges, blow up tunnels and strafe trains. Myriad first-hand accounts and period photography reveal the spectacular success enjoyed by the Thunderbolt in the MTO in the final year of the war.
