JG

JG is a common initialism used to denote a variety of terms across different fields. In military history, JG most often refers to Jagdgeschwader, the designation for a fighter wing of the German Luftwaffe in World War II. These wings were numerically labeled, such as JG 2, JG 27, and JG 52. Jagdgeschwader units were active in major air battles and played a central role in Luftwaffe operations, with JG 52 noted for its high tally of aerial victories.

In literature and culture, J.G. is used as the initials of some writers, notably J. G. Ballard, the British author James Graham Ballard (1930–2009). He published novels such as Empire of the Sun and Crash.

In business and finance, J.G. Wentworth is a U.S.-based financial services company that specializes in structured settlements and annuities.

Because it is an initialism with multiple uses, the meaning of JG depends on context. The acronym can refer to historical military units, individuals known by their initials, or contemporary organizations, among other possibilities.
