Space Research Corporation was a corporation founded by Gerald Bull, after the budget for his research at Project HARP for the United States and Canadian federal governments was cut in 1967, in order to commercialize the technology of long-range artillery. Project HARP's assets were then given to the newly formed SRC. The main facility of SRC was , straddling the Canada–United States border between Highwater, Quebec, and Jay, Vermont. Affiliated companies included: SRCQ (SRC Quebec); Shefford Electronics Corp (SEC of Granby, Quebec); SRCI; Paragon; PRB (Belgian corporation); and SRCB (SRC Belgium). Background In 1965, McGill University sponsored the Aeroballistic Laboratory (alternately the McGill Aeroballistic Test Center) at Highwater, Quebec. Dr. Gerald Bull was the Director. The manager was R.C. Stacey. Artillery exports During the next decade, SRC worked for a number of governments including the People's Republic of China, Chile, Taiwan, and especially South Africa, and SRC contracted with the South African company Armscor. SRC's main product was a modification of the NATO- and U.S.-standard 155.4 mm (6") artillery cannon, the GC-45 howitzer ("GC" stood for "Gun, Canada", 45 for 45-calibre long), firing either NATO-standard 155 mm M107 rounds, or, more typically, a new shell of Bull's own design. The new "pointy" shell, designated ERFB (for extended range full bore), offered considerably better aerodynamics than the original; its spin was moderated by fins on the shell rather than only by rifling in the barrel, and the round was supported in the gun barrel by four aerodynamic nubs allowing the middle of the shell to be elongated and thus reduce drag. The shell was initially spun in the same way as conventional artillery rounds with a driving band towards the base. The result was a gun that could out-range the original by as much as 30%, while at the same time being much more accurate. Standard NATO and US artillery of the time had a range of less than while the GC-45, ERFB combination had a range of . With the innovative base-bleed system developed in Sweden this range could be increased to without loss of accuracy. South African connection The GC-45 work was paid for by the South Africans, but it has been claimed that Bull did the work largely at the urging of the United States Central Intelligence Agency (CIA) who considered South Africa as a defence against Soviet operations in Angola.
