The X-Series, often referred to as X-Planes or X-Craft, have been in existence since World War II. The X-Series can trace its origin from the Research Aircraft Programme launched by the NACA (now NASA) together with the US military to investigate transonic and supersonic flight.

The first success came in October 1947 when the X-1 broke the sound barrier, with many successes following on, including the X-15 reaching mach 6.7 20 years after the first success with the X-1.

The current X programme is different from the earlier programme in several ways. One of the important differences which can be clearly seen is the size of the craft being tested. The current X-programme uses largely subscale craft which are often unmanned &endash; a clear change from the earlier years of the programme when many test pilots risked their lives flying the early X-planes.

A table listing the X-planes, together with brief information concerning dates, manufacturer, reason for project, etc. has been created on another page. To access this index page click here.
