| Source measurement | — | The Palmaria is an Italian self-propelled howitzer using the 155 mm (6.1″) NATO -standard artillery calibre.[source]Palmaria (artillery) · Lead; only the objects and conditions stated in this passage The primary armament is a 155 mm howitzer, with a secondary 7.62 mm machine gun or 12.7 mm machine gun on anti-aircraft mount and four 76 mm forward-facing smoke grenade dischargers on either side of the turret. The howitzer has an automatic loading system, providing a rate of fire of one round every 15 seconds or a burst-fire rate of three rounds every 25 seconds. The loader has 23 ready rounds, with seven more rounds stored in the hull. Including manual reloading of the charge, the overall firing rate is normally one round per minute for one hour. Intense firing is four rounds in one minute. Sustained fire is one round every three minutes for an indefinite period. A wide variety of 155 mm munitions are available, including specially developed Simmel rounds with a range of 24.7 km and rocket-assisted ones with a range of 30 km.[source]Palmaria (artillery) · Design; only the objects and conditions stated in this passage The turret is hydraulic with manual backup, and has 360 degree rotation with elevation limits of -4 to +70 degrees. It has its own auxiliary power supply which conserves fuel for the main engine.[source]Palmaria (artillery) · Design; only the objects and conditions stated in this passage The Palmaria is powered by a 750 hp MTU MB 837 Ea-500 (or 1,000 hp Ka-500) 4-stroke, turbocharged, 8-cylinder multifuel engine coupled to a Renk RK 304 transmission. The Palmaria has torsion bar suspension with seven roadwheels and five return rollers on either side. The drive sprocket is located at the rear while the adjustable idler sprocket is at the front.[source]Palmaria (artillery) · Design; only the objects and conditions stated in this passage Libya was the first country outside Italy to adopt the Palmaria, initially ordering 210 in 1982. Their army's artillery strength in 2004 included 160 Palmaria. Several were destroyed during the First Libyan civil war as a result of multinational military intervention .[source]Palmaria (artillery) · Operational history; only the objects and conditions stated in this passage |
