FH 77 155 mm Field Howitzer SystemThe FH 77 is still one of the world's most revolutionary towed field artillery systems. It has an on-mount auxiliary power unit (APU) that gives the system its self-propelled capability and supplies power to the hydraulically supported operations, making it easy to handle. It also has the unique advantage of having a fully integrated land navigation system that gives the coordinates of the gun position and automatic alignment of the barrel.
The FH77 B is now integrated with a 6x6 all-terrain vehicle making it an extremely powerful, highly mobile artillery system. It's into-action time is less than 50 s. An artillery sequence: into action; fire 8 rounds; out of action and move 500 m takes less than 3 minutes. The gun has a range of 30 km, it can fire 3 rounds within 13 s and a has sustained rate of fire of 8 rounds/minute. On the move the gun crew is transported in an armoured cabin. The on-mount ammunition boxes, in effect magazines, have the same level of protection as the crew compartment. The FH77 B has its own land navigation system, eliminating surveying and alignment and the complete system has very low LCC.
