Notes: This gun was replaced in production by the FH-77B. It is basically similar to the FH-77B, but is towed at a lower speed, does not have the ammunition-handling crane, and uses semi-combustible cases for the charges. The sights are not as efficient (+1), and the fire control computer is not integrated into the system. It does have a power rammer for loading. It is equipped with an APU.

Notes: This is the newer of the Swedish towed howitzers. Changes were made to handling, cross-country mobility, and a mechanized ammunition handling system was introduced. This weapon is also used by Nigeria, and India, who is actually the largest user of this weapon. The FH-77B differs from the FH-77A in the length of the barrel, the use of bag charges, and a new hydraulic loading system using a grab crane to lift projectiles off the ground and into the gun. The weapon has a fire solution computer, a telescopic sight (+2), and a fitting for a night sight. The gun is fitted with an APU for short moves and to assist in bringing the gun into action and to power the mechanisms.

Notes: This is a Swedish light howitzer in use since shortly after the Second World War. It is of standard construction, and has a loading tray that aids in loading. Controls are hydraulic, and the is jacked up on a four piece platform that allows 360 degrees of traverse, before firing.
