FIELD: military equipment, in particular, ammunition, applicable in development of salvo-fire jet projectiles. SUBSTANCE: projectile has a nose cone and a jet section, aerodynamic stabilizer and centering thickenings. A ring frame is formed behind the nose cone at a distance not exceeding the caliber, at least one pair of circular grooves successively arranged on the opposite sides of the frame are made on the outer and inner sides of the frame. The outer grooves diameter-to-inner grooves diameter ratio makes up 0.95 to 1.05. The distance between the grooves is selected within 0.75 to 1.25 of the frame thickness. The outer grooves width-to-inner grooves width makes up 0.45 to 0.85. The inner grooves are filled with an elastic material. EFFECT: suppressed vibrations caused by operation of the units, devices and equipment in the nose cone. 3 dwg
