harp gun

In the 1960s, ballistics engineer Gerald Bull persuaded the Canadian and US defence departments that it might be possible to fire a payload into space from a very large gun.

Cue Project HARP (High Altitude Research Project), which rolled out a US Navy 16in (406mm) piece to lob projectiles over the Atlantic from a base in Barbados.

With an initial barrel length of 20m, later extended to 40m, HARP eventually managed to propel a 180kg slug at 3,600m/s to an altitude of 180km.
