Al-Fao
Al-Fao was a project for a self-propelled artillery system designed for the former Iraqi Army by the Canadian weapons engineer Gerald Bull. It would have been one of the world's most powerful artillery pieces, with a 53-caliber, gun firing 109-kilogram shells over a range of. The Al-Fao system was to weigh 44 tonnes, and its 550 hp engine was to give it a top speed of on roads, and cross-country. The Al-Fao's autoloader was to provide it with a rate of fire of four rounds a minute.
A self-propelled howitzer using the same 155 mm gun as the South African G6, similar to the Al-Fao and named Majnoon, was also designed by Gerald Bull on an Iraqi order.
Design
Both the Al-Fao and Majnoon prototypes used a 6×6 chassis with a turret mounted atop the rear with a large rear door to replenish the vehicle ammunition supply, two doors on both sides for the crew, and two hydraulic rams to damp the recoil forces on the chassis. The Majnoon had a gun fitted with a fume extractor and a three-slotted muzzle brake, while the Al-Fao was fitted with a gun also fitted with a fume extractor but with a double baffle muzzle brake. A direct fire sight was fitted on the left side of the ordnance.The lower part of the hull had small hatches for the crew on either side, while the cab had a single hatch for the driver, who sat in front of the powerpack. Both designs had no shutters on the windshield, used a Mercedes-Benz diesel engine developing coupled with a manual transmission, and a central tire pressure regulation system; Christopher F Foss noted that the prototypes lacked spades, which would provide a more stable firing platform if fitted.
The Al-Fao and Majnoon could fire Extended range full bore and ERFB-base bleed ammunition, which were already in use in Iraq with the 155 mm GHN-45 and the G5 howitzer. The 210 mm shell design was an enlarged version with a much larger high explosive payload.
