Range of normal flight of the projectile was 9650 m, a projectile with rocket boosters - 20 000 m. The range of munitions are also piercing, Nuclear and suggestive laser projectiles. Fighting compartment mortar "Tulip" is located in the middle and rear parts of the body. In the middle of the entire length of the crew compartment is mechanized packing a drum-type min. On both sides of the stacking, on the boards, seat crew members attached: on the right side – anterior – operator, rear – gunner, on the left side – operator.
In the department of management are a driver and commander.
The mechanized laying placed two kinds of mines:
• high-explosive 53-F-864 by 10 pcs (in the front and rear of the drum), Total 20 pcs;
• active-reactive ARM-0-VF2, 10 pieces throughout the length of the drum laying.
Min Feed guides chambering mechanism is made by means of three cylinders, fixed by stacking axis. Submission of regular minutes shall be held alternately extreme cylinders, active and reactive – a middle cylinder. After issuing one of a number m, It occurs drum rotation by one step relative stacking axes, and another number m becomes over trays cylinders. If a command to rise, ming lying cylinder upward and abuts the housing in the guide tube, after which the cylinder rod moves down, ming and remains on the guide tubes. After equipment charges and mines reversal pipe loader mortar on line rammer, resting on its base in the stabilizer mines,pushes it along the guide rails in the trunk, after which the loading rod is returned back Klotz.
mortar tube is moved into the firing position, ensuring readiness for firing mortar. Management of special units of self-propelled mortar "Tulip" is performed electro-hydraulically.
Firing of a mortar gunner carries out using the keypad, from outside the machine. Due to the hinge connection of the frame with mortar base plate, the presence of damping devices and elastic frame due to the shunt body, provided permissible acceleration on the crew of the shot exposure stability and normal. With the loading with ground mine via loader supplied to the machine and is placed directly on the loading rod guide tubes. Further loading is the same, as when shooting from pilings.
With elektrogidroprivoda stowed mortar tube is mounted parallel to the roof and is tightened with a clamp namitka using mounting frame to the machine frame.
