Launch complex

(aerospace engineering) The composite of facilities and support equipment needed to assemble, check out, and launch a rocket vehicle.

The composite of facilities and support equipment needed to assemble, check out, and launch a rocket-propelled vehicle. The term usually is applied to the facilities and equipment required to launch larger vehicles for which a substantial amount of prelaunch preparation is needed. Small operational rockets may require similar but highly simplified resources on a much smaller scale. For these, the term launcher is usually used. See also Space flight.
