Before the ATMOS 2000 truck gun was ordered, the Philippine Army did not have a self-propelled howitzer. Its artillery unit was composed of 14 M-71 155mm howitzers, 12 M114A1 155mm howitzers and hundreds of 105mm towed howitzers. It is the 14-door M-71 that can be regarded as modern, which is still equipped by the Marine Corps. The Philippines also knows its shortcomings, so it has decisively implemented a 15-year modernization plan, which began in 2012 and will continue until 2027 in accordance with the Republic Act (RA) 10349 revision. The total cost is expected to exceed 40 billion. U.S. dollars, so we also see that the Philippines has successively received new weapons in the near future. On May 6, 2020, the Philippine Department of Defense (DND) issued a "Notice of Implementation" (NTP), spending US$47 million to purchase 12 Elbit Systems’ ATMOS 52-diameter 155mm truck guns, ammunition and spare parts for the Philippine Army. To strengthen maritime defense forces. According to the plan, the contract will be completed in April 2022, and Elbit's production is very rapid, and the first batch will be delivered at the end of 2021.
The ATMOS 2000 155mm truck gun was actually self-funded and developed by Soltam, Israel. Its main purpose is to face the international market. It has been conducting extensive tests from 1999 to 2004 and has won orders from many countries. In October 2010, Saltam was sold to Elbit Systems and became its wholly-owned subsidiary. Israel did not purchase this system to equip its own troops until 2017. The ATMOS 2000 truck gun can choose a variety of 6X6 and 8X8 off-road chassis according to the user's choice. Its gun caliber can be 39 times, 45 times, 52 times the caliber, and it can even be equipped with a Russian-made 130 mm M-46 cannon, so it can meet different countries. Requirements. The base type of the vehicle is the T815 VVN 6x6 off-road chassis with armored cab. Its combat weight is 22 tons, the vehicle length is 9.5 meters (not counting the gun), the width is 2.65 meters, the height is 3.24 meters, and the bottom distance is The ground height is 410mm, and it is also equipped with a central tire charging and discharging system. It has 4 passengers and a T3-930-31 diesel engine with a maximum output of 235kW/2200rpm, a maximum road speed of 80km/h, and a road trip of 1000km (consumption The oil volume is 460L), the wading depth is 1.4m, it can cross the 0.6-meter wall and cross the 0.9-meter trench. The Philippine version may still be too pull-out chassis equipped with a newly designed armored cab. The side of this cab looks very similar to the cab of the MAN HX81. It should be able to accommodate the commander, gunner/sighter and 2 ammunition loading. It can defend against at least 7.62×51mm ordinary shells and 155mm shell fragments. It has a collective anti-chemical and air-conditioning system. It also has an auxiliary power unit (APU) installed to lift the hoe and drive the artillery control equipment to automatically aim at the target. Its hydraulic station The hoe also doubles as a standing platform for the crew.
The Philippine version still uses a 52-diameter 155mm ATHOS 2052 howitzer with a combat conversion time of 1.5 minutes. The gun has a pitch angle of 0-70 degrees and a horizontal angle of 50 degrees. It uses computer full hydraulic control, horizontal sliding breech block, and is equipped with There is a semi-automatic loading device, which launches ordinary ammunition with a range of 30 kilometers, a long-range full-bore bottom row grenade, a range of 41 kilometers, a recoil stroke of 850 to 1100 mm when shooting, a burst firing speed of 3 rounds/20 seconds, and a combat fire The speed is 4-9 rounds per minute. The artillery has 27 rounds of ammunition, the center of the left side is the shell box, and the right side is the propellant box. The gun is also equipped with advanced artillery fire control systems, including navigation and positioning, aiming systems, and ballistic calculation systems. The display system includes a data terminal for the position of the gunner and the commander in the cab, and a remote control display for the loader behind the vehicle. The shooting coordinates provided by the neighboring troops are automatically calculated. The muzzle velocity of the projectile can be transmitted to the fire control system through the RSL muzzle velocity radar during shooting to improve the accuracy. The gun can easily match the customer’s existing C4I ( Command, control, communication, computer and intelligence) system connection.
The Philippines chooses the ATMOS 2000 truck gun because of its low price, lower lifetime cost, easy operation and maintenance, and greater strategic mobility. It does not require a trailer and has the advantages of high battlefield mobility. It is also more suitable for shooting. The running combat environment is easier for troops to master than complex crawler self-propelled artillery. Of course, the performance of this type of truck gun has to rely on the support of the new combat information system, and the combat performance of the backward-level equipment of the Philippines will be greatly reduced. Now it's the turn of the Philippine artillery to accept the baptism of modernization!
