The Martin B-57 Canberra is a United States-built, twin jet engine tactical bomber and reconnaissance aircraft that entered service with the United States Air Force (USAF) in 1953. The B-57 was a licence-built version of the English Electric Canberra; the Glenn L. Martin Company later modified the design to produce several unique variants.
The Canberra was the first U.S. jet bomber to drop bombs during combat, its retirement in 1983 ended the era of the tactical bomber that had its beginning with the World War I De Havilland DH-4. The two remaining flightworthy WB-57Fs are technically assigned to the NASA Johnson Space Center, next to Ellington Field in Houston, as high-altitude scientific research aircraft, but are also used for testing and combat in the U.S. and Afghanistan.

Streaking into the night sky, a Su-27 rips apart the night with fully lit afterburners. The armament of the Su-27 consists primarily of air-to-air weaponry, though later variants of the -27 could carry air-to-ground weaponry. Typical air superiority loadout of an Su-27 would be six R-27s and two R-73s. (Photo)
