{| |} The Grahame White Type XV was a military trainer biplane produced in the United Kingdom before and during World War I. It is often referred to as the Box-kite, although this name more properly describes the Grahame-White Type XII, an earlier aircraft made by the company, from which the Type XV was derived. It is also known as the Admiralty Type 1600, since the first aircraft of the type purchased for the Royal Naval Air Service was given that serial number, and contemporary practice was to assign type numbers based on the serial number of the first example in service.
