Description
The GC-45 (Gun, Canada, 45) is a 155 mm howitzer designed by Gerald Bull's Space Research Corporation (SRC) in the 1970s. Versions were produced by a number of companies during the 1980s, notably in Austria and South Africa. The most publicized use of the design was in Iraq, where the GHN-45 variant used by some Iraqi artillery units had a longer range than any coalition cannon systems. This initially caused considerable worry on the part of the allied forces in the Persian Gulf War
