This collection of squadron histories has been prepared by the USAF Historical Division to complement the Division's book, Air Force Combat Units of World War II. The 1,226 units covered by this volume are the combat (tactical) squadrons that were active between 7 December 1941 and 2 September 1945. Each squadron is traced from its beginning through 5 March 1963, the fiftieth anniversary of the organization of the 1st Aero (later Bombardment) Squadron, the first Army unit to be equipped with aircraft for tactical operations. For each squadron there is a statement of the official lineage and data on the unit's assignments, stations, aircraft and missiles, operations, service streamers, campaign participation, decorations, and emblem.

This book is concerned primarily with the combat (or tactical) groups that were active during the Second World War. Although such groups had numerous designations, nearly all fell within four major categories: bombardment, fighter, reconnaissance, and troop carrier. The book covers both the combat groups that served overseas and those that remained in the United States. It also covers combat organizations above the group level. It does not deal with provisional organizations or with air base, maintenance, supply, medical, transport, and other service or support organizations. Although this book is devoted exclusively to organizations that were active during World War II, its coverage of those organizations is not confined to the World War II period. Instead, each organization is traced back to its origin and forward to 1 January 1956, with later activations being mentioned if they took place prior to the time the draft of the book was prepared in 1957-1958. The organizations are presented under the designations they carried on 2 September 1945. For each organization there is information concerning insigne, lineage, operations, assignments, aircraft (for groups only), components, stations, commanders, campaigns, and decorations.

In Fifteenth Air Force against the Axis: Combat Missions over Europe during World War II, historian Kevin A. Mahoney provides a detailed combat history of the crucial role played by this air force from November 1943 through May 1945. Presented by month in chronological order, Mahoney describes all the major bombing and fighter missions carried out by this air force within a strategic context. Each chapter includes an introduction describing developments in the evolution of the strategic air campaign against the Germans, highlights the purpose and importance of the month’s operations, and reviews the Luftwaffe’s resistance and changes in tactics and important developments in the Fifteenth Air Force’s organization. Each monthly narrative further explores most missions, detailing the number of aircraft lost during these missions. Losses are based on an exhaustively researched database compiled by Mahoney that contains details of almost 3,000 aircraft. Target damage is mentioned, while enemy opposition is also described for each mission. Appendices include four short essays on bombing operations (planning and flying of missions, tactics and techniques, bomb types, and bombing accuracy), tactics employed by fighter escort in aerial combat and strafing, combat crews and their aircraft (including a comparison of American fighters and bombers, the training of the crews, and their combat tours), and the Fifteenth Air Force command structure (including the use of intelligence, photo and weather reconnaissance, and the considerable effect of weather on Fifteenth Air Force operations). This work of military history is ideal for students and scholars of the air war in Europe.

Petlyakov's Pe-2 was the most numerous Soviet twin-engined bomber of World War 2, the aircraft being used as a dive-bomber, ground attack platform and dedicated reconnaissance type. The first examples entered service in August 1940, and by the time production came to end in late 1945, no fewer than 10,547 examples had been built. These equipped more than 80 bomber air regiments, and of the latter, two were accorded Guards Air Corps status, as were six air regiments. Amongst the former was the 2nd Guards Bomber Air Corps, which was commanded by the legendary General Polbin, who was twice made a Hero of the Soviet Union. Pe-2 bomber and reconnaissance versions (the latter in service with four Guards reconnaissance air regiments of the Air Force and one regiment of Naval Aviation) were extensively used from the frozen Arctic north to the balmy Crimea front. A number of Pe-2 also saw brief combat against Japan in the final weeks of World War 2.
