B47

B47 is an alphanumeric designation used for several unrelated items in different fields. The most prominent use is in aviation, where the B-47 Stratojet was a landmark United States Air Force bomber in the early jet era. The designation also appears in transportation and as a general model or catalog code in various industries.

Boeing B-47 Stratojet

The B-47 Stratojet was developed by Boeing in the late 1940s and first flew in 1947. It was the United States' first production jet-powered strategic bomber and played a pivotal role in the early jet age. The aircraft featured six turbojet engines mounted in pairs in underwing pods and a swept-wing design. It entered service in the early 1950s and remained influential through the 1950s, contributing to advances in bomber reach, speed, and aerial reconnaissance. The B-47 was produced in numerous variants and informed subsequent jet bomber and aircraft designs before being retired from frontline service in the mid-1960s.

Other uses

Beyond aviation, B47 is used as a route designation for certain public transit bus services in several cities, reflecting its role as an alphanumeric label rather than a single, unique entity. In addition, B47 appears as a model or catalog code across different industries, where the letters and numbers serve as an internal designation.
