Beginning in 1961,Guest Posting the HARP project was largely created due to the concerns and insistence of the talented engineer Gerald Bull, a controversial ballistics engineer and he and his project, but ultimately successful, the engineer who led the entire project. Bull developed the high-speed weaponry technique while working on the Ballistic Missile (ABM) and Intercontinental Ballistic Missile (ICBM) research at CARDE in the 1950s, firing high-speed interceptor rocket models, unlike other researchers who proposed to use the construction of higher wind tunnels, which would have been much more expensive.
The ABM project eventually ended without providing a working system, but Bull was convinced that the missile systems he developed would have had potential and in this way, he began to look for other ways of using technology. He clearly needed the trust and funding of his project. Funding for this project came from the Defense Production Department in the form of a $ 500,000 grant and a $ 200,000 loan from the McGill Board of Governors. The United States has been testing new ICBM systems and has requested repeated testing of new reentry vehicles. Bull suggested that the program could be run through its method with much lower spending if the test vehicles would be lifted from a large cannon, unlike the classic rocket method. This would also allow the test program to be very accelerated since repeated pulling was easy to arrange compared to the repeated use of the missiles. The key concept was the use of an oversized gun that throws a sub-dimensional vehicle mounted in a shoe, allowing it to be pulled (thrown, ejected) with a very high acceleration, reaching very high speeds. The entire assembly of the test cannon was embedded in a mixture of sand and epoxy, proving more than capable of withstanding the launching rigors. The project was based on a flight line at Seawell Airport in Bar
