high-accuracy artillery guided ammunition, applicable in constructions of artillery guided jet projectiles. SUBSTANCE: the artillery guided jet projectile has a head section, jet engine, whose outside diameter equals the projectile caliber, in the form of fitting quadrants with powder charges in their cylindrical chambers fastened in a common section by the front cover and the nozzle unit, blade-type fin, whose blades are positioned in grooves between the quadrants. The outer surface of each fitting quadrant is formed by a cylindrical surface, whose axis is shifted relative to the axis of the cylindrical chamber to the periphery by 0.14 to 0.16 of the radius of the latter, and a tapered increased thickness is made on the front end of each quadrant, the outer diameter of this increased thickness equals the projectile caliber. The grooves between each adjacent pair of quadrants are formed by the truncated parallel planes of the outer surfaces of the quadrants that are equidistant to the side surfaces of the fin blades and conjugate to the outer cylindrical surface of the quadrants. EFFECT: enhanced accuracy of fire in the unguided path of the jet flight trajectory to the target. 2 cl, 4 dwg
