ATMOS 2000 155mm.

The ATMOS 2000 is a 155mm truck-mounted wheeled self-propelled howitzer that was designed by the Israeli company SOLTAM Systems. The first information about the vehicle was released in 2001. It is an enhanced version of the standard ATMOS. ATMOS 2000 has been developed by Soltam Systems as a private venture. It is aimed mainly at the export market, although it has already been demonstrated to the Israel Defence Force. The ATMOS 2000 is now manufactured and marketed by the Israeli company Elbit Systems. The development of the ATMOS 2000 was based on a 155mm 52 caliber cannon mounted on 6x6 Tatra truck chassis, built under license in India. The artillery system was also developed with other armament solutions including a Russia M-46 130mm gun, a D-30 122mm cannon, and also 155mm 39, 45, and 52 caliber barrels. Elbit Systems has also developed different variants using other truck chassis in 6x6 and 8x8 configurations. The ATMOS is now in service with several countries including Azerbaijan, Botswana, Cameroon, the Philippines, Thailand, Uganda, and Zambia. There is also a Romanian version, called ATROM that uses the same 155mm Soltam gun on a locally developed ROMAN 26.360 DFAEG 6x6 truck chassis. This project was put on hold after three prototypes were built. Poland has also developed the Kryl 155mm howitzer, using a domestically made version of the ATMOS 2000 mounted on a Polish-made 6x6 Jelcz 663.32 truck chassis. On January 6, 2023, Colombia confirmed an order of 18 ATMOS 155mm self-propelled howitzers. On January 26, 2023, the Danish Ministry of Defense announced that after the donation to Ukraine of 19 French-made CAESAR 155mm self-propelled howitzers that Denmark had ordered in May 2017, the Danish Government decided to acquire new artillery systems and negotiate with Israel to acquire 19 ATMOS 155mm wheeled self-propelled howitzers. On April 20, 2023, Colombia officially announced the purchase of 18 ATMOS. On November 29, 2023, the Israeli Company Elbit Systems announced the signature of an agreement with Romania for the production of 155mm ATMOS howitzers.
