A glide bomb or stand-off bomb is a standoff weapon with flight control surfaces to give it a flatter, gliding flight path than that of a conventional bomb without such surfaces. This allows it to be released at a distance from the target rather than right over it, allowing a successful attack without the aircraft needing to survive until reaching the target. World War II-era glide bombs like the German Fritz X and Henschel Hs 293 pioneered the use of remote control systems, allowing the controlling aircraft to direct the bomb to a pinpoint target as a pioneering form of precision-guided munition.
The term glide bombing does not refer to the use of glide bombs, but a style of shallow-angle dive bombing.
In October 1914 Wilhelm von Siemens suggested what became known as the Siemens torpedo glider, a wire-guided flying missile which would essentially have comprised a naval torpedo with an attached airframe. It was not intended to be flown into a target, but rather at a suitable altitude and position, a signal would be transmitted, causing the airframe components to detach from the torpedo which would then enter the water and continue towards its target. Guidance signals were to be transmitted through a thin copper wire, and guide flares were to be carried to help control.
Siemens-Schuckertwerke was already occupied with remote controlled boats (the FL-boats or Fernlenkboote), and had some experience in this area. Flight testing was performed under the supervision of an engineer called Dorner from January 1915 onwards, using airships as carriers and different types of biplane and monoplane glider airframes to which a torpedo was fitted. The last test flight was performed on February 8, 1918.
It was planned to use the Siemens-Schuckert R.VIII bomber as a carrier craft, but the Armistice stopped the project.
