Introduction. Weapons are widely used in crimes. Firearms, firearms of limited destruction seized by law enforcement agencies, gas, pneumatic weapons, cartridges for the specified types of weapons, traces of a shot on various obstacles, fired bullets and other shells, fired cartridges are among the main objects of forensic ballistic examination. Theoretical analysis. Forensic ballistic expertise is carried out strictly in accordance with the expert methods. The effectiveness of solving diagnostic and identification problems depends on the relevance, reliability, availability of reference information on firearms and other weapons, ammunition for these weapons, and other objects. In the process of expert research, various information systems of identification and non-identification (reference) purposes are used. Empirical analysis. The potential capabilities of information systems are not fully utilized due to various circumstances, including: fragmentation, special access to information resources, limited functionality of existing identification ballistic systems, insufficiently effective search algorithms, etc. Results. In order to eliminate these and other circumstances, it is proposed to combine the most relevant and sought-after arrays of information about firearms and other weapons, ammunition to it, and other data relevant to forensic ballistics into a single information system based on automated search tools with the prospect of introducing artificial intelligence technologies expertise.
