Project HARP, for high altitude research project, was a joint venture of the United States Department of Defense and Canada's Department of National Defence created with the goal of studying ballistics of re-entry vehicles and collecting upper atmospheric data for research. Unlike conventional space launching methods that rely on rockets, HARP ...

2016年9月2日 · The HARP gun at YPG set two world records in its short three-year run: The first for altitude. It shot up 111 miles high. The second was for the most gunpowder loaded into a gun: 1225 pounds.

2022年12月16日 · The US Army supplied Bull with two 16-inch naval gun barrels—the largest artillery piece in the American arsenal, each weighing 140 tons—complete with a land mount and surplus powder charges, a heavy-duty crane, and a $750,000 radar tracking system. The guns were welded together to produce a single barrel, 119 feet (36 m) long.

By the 1930's the first liquid propellant rockets began appearing and gun propulsion was soon abandoned as a means of space launching. The High Altitude Research Program (HARP) was unique in the history of the space age.

HARP, for High Altitude Research Project, was a study of the upper atmosphere by instruments shot from a cannon. The project was conducted in the 1960s by scientists of the McGill University in Montreal, who named their vehicle the "Martlet", an old name for the martin bird; the shield of the McGill University in Montreal displays three red ...

2013年5月1日 · In lay terms, the HARP project was established to create a cartoonishly large gun to shoot things into space. Designed by mad ballistics engineer Gerald Bull, the gun itself was originally...

The HARP gun, also known as the High Altitude Research Project gun, is an intriguing piece of technology. The gun was built in the 1960s by Canadian engineer Gerald Bull with the goal of being a satellite launch system .

2014年12月27日 · I found myself reading about Project HARP, the High Altitude Research Project, which was a project funded to explore the possibility of creating high speed guns that could essentially replace certain types of rockets. In 1966, the third and final gun was constructed in Yuma, Arizona.

How A Giant Space Gun Ended Up In The Middle Of The Arizona Desert

The HARP in Barbados was acquired from the American arsenal and was the largest artillery piece to be sourced - a 16-inch battleship gun complete with a land mount and surplus powder charges. A heavy-duty crane moved the gun and a $750,000-dollar radar tracking system was contributed by the U.S. Army's Ballistic Research Laboratory (BRL).
