Aerial bomb fuse from World War I
Object No. 2014/87/4
This aerial bomb fuse was developed in World War I for use on ordnance which was deployed from aircraft. The arming vane assembly operates once released from the aircraft - which removes the safety pin from the fuse - enabling the blades to turn like a propeller, exposing the detonator to a firing mechanism, which would be activated when the bomb struck a solid object. This fuse was likely used on a Cooper 20 pound aerial bomb. Wars have always driven technology at a rate which peace time does not allow for. Technological resources are focused, and materials made available to augment rapid progress. World War I was the first war on an industrial scale. This enabled design and production on a scale and with applied precision never known before. This fuse is an example of industrially fashioned and technologically advanced ordnance from the early twentieth century. Damian McDonald Curator August 2014

HISTORY
Notes
World War I was the first war in which aircraft were used extensively. The ability to spot targets, and deploy explosives was utilised strategically, particularly by the British and German forces. In order to maximise the small amount of explosives an aircraft could carry and deploy, detonation control was imperative. This bomb fuse was developed to ensure that, once the payload was released, the fuse would arm the detonator away from the aircraft, and and prior to impact - which would explode the device.
