155mm GHN-45

The GHN-45 is a 155mm towed howitzer developed by NORICUM of Austria, based on a design by Gerald Bull's Space Research Corporation. It is renowned for its exceptional long-range capabilities, particularly when firing extended-range full-bore base bleed (ERFB-BB) ammunition.

Developed in the late 1970s by Noricum to bypass the limitations of standard NATO artillery, the GHN-45 was designed to achieve unprecedented range and accuracy by refining Gerald Bull's GC-45 design. Entering production and service in the early 1980s, the weapon was aggressively marketed globally, though its sales eventually triggered a major political scandal in Austria regarding illegal exports to warring nations. The howitzer saw extensive combat during the Iran-Iraq War, where both sides utilized its superior range to devastating effect, and it was later deployed during the Gulf War. Today, while mostly retired from European inventories, the GHN-45 remains in active service with the Royal Thai Army and is remembered as a landmark achievement in modern ballistic engineering.
