Within the scope of the 35 mm Air Defense System Modernization (HSSM) and Particle Ammunition Supply (PMT) Contract conducted by Aselsan under the guidance of the Presidency of Defense Industries, 100 thousand ATOM 35 mm Air Burst Munition electronics were manufactured at Aselsan facilities.

ATOM 35mm Air Burst Ammunition provides high hit probability against various types of air and land targets, with the ability of precise time counting and the capability of being programmed during firing by taking the muzzle velocity into consideration. Thus, barreled systems can be used as effective air defense weapons. Modernized Towed Guns and KORKUT Systems, when used with ATOM 35 mm Air Burst Ammunition, become effective against traditional air targets such as fighter jets and helicopters, as well as modern air threats such as air-to-ground missiles, cruise missiles and unmanned aerial vehicles. ATOM 35 mm Air Burst Ammunition was developed by Aselsan as the main contractor and by subcontractors MKEK and TÜBİTAK SAGE and has become an important element in layered air defense.
