Jules Verne Launcher
American gun-launched orbital launch vehicle. Following the failure of the US government to fund further development of the SHARP light gas gun, John Hunter founded the Jules Verne Launcher Company in 1996 in an attempt to fund commercial development of the concept.

The company planned to first build a prototype Micro Launcher system. This would fire 1.3 mm projectiles (barely visible to the naked eye) and demonstrate several new technologies, including the use of three pairs of supplemental gas injectors along the barrel (as used in the Oberth gun and V-3). The full-scale gun would be bored into a mountain in Alaska for launches into high-inclination orbits. The gun would have a muzzle velocity of 7 km/second and fire 5,000 kg projectiles. The payload would be 1.7 m in diameter and 9 m long. Following burn of the rocket motor aboard the projetile, a net payload of 3300 kg would be placed into low earth orbit.

SHARP experience indicated maximum fire rate of the gun would be once per working day. A single gun could orbit over 1000 tonnes a year into orbit at a cost per kg one-twentieth of conventional rocket launchers. The economic breakeven point was calculated to be between the first 50 and 100 launches.

Payloads would be subjected to accelerations of about 1,000 G's during launch, so Hunter recruited specialists to design prototype hardened satellite systems. JVL was apparently still operating in 1998, but no investors came forward to finance the multi-billion dollar development cost.

LEO Payload: 3,300 kg (7,200 lb) to a 185 km orbit at 60.00 degrees. Launch Price $: 2.000 million in 1996 dollars.

Status: Design 1996.
Payload: 3,300 kg (7,200 lb).
Apogee: 185 km (114 mi).

  • Gun-launched Artillery dominated military ballistics from the earliest use of gunpowder. In 1865 Jules Verne could only realistically consider a cannon for a moon launch in his influential novel. Even after the rocket established its primacy as a method of accessing space, Canadian Gerald Bull began a life-long struggle to use guns for cheap access to space. His successes could not generate funding to continue. Others since then have pursued the technology, convinced it was the only way for low-cost delivery of payloads to orbit. More...
