The anti-submarine weapon system consists of two AB2 12 helicopters, A- 184 wire-guided torpedo and triple MK32 light anti-submarine torpedo tubes.

Two AB2 12 helicopters are long-range anti-submarine weapons with a maximum takeoff weight of 5.08t They are equipped with APS- 105 search radar, TG-2 relay guidance system, TACAN navigation system, electronic reconnaissance and jamming equipment and ASQ- 13B suspended sonar. Anti-submarine weapons are two MK46 or A244 anti-submarine torpedoes. This class of ships can also be equipped with 1 Neptune helicopter.

Two B5 16 wire-guided torpedo launch tubes are arranged on the left and right sides under the tail helideck. The 533mm A 184 torpedo is launched. A 184 is an electric two-speed, wire-guided, active and passive acoustic homing torpedo. The velocity is divided into 37kn and 24kn, and the range at 37kn is 15000m. It is said that the mine is equipped with 6? Eight torpedoes. A 184 torpedo is used as a medium-range anti-submarine weapon of this class of ships.

Two triple MK32 torpedo tubes are used to launch MK46 or A244 anti-submarine torpedoes as medium and short-range anti-submarine weapons.

In addition, 1 set of SLQ-25 "water essence" towed torpedo bait is installed at the stern of the ship as a soft killing means against torpedo attack.

(2) Air weapon system

The air-to-air weapon system consists of albatross Aspide missile system, 127mm naval gun, Dardo short-range weapon system and two 20mm naval guns.

The eight-pack launcher of the albatross "Agkistrodon" missile system is installed on deck 02 in front of the bridge, and there is a magazine under it, which contains 16 bomb, which can load four missiles at the same time. It is reported that each loading time is 4 minutes. Viper missile is guided by active radar, with a range of 13km and a firing height of 15? 5000 meters.

"Otto Melara" 1 single tube 127mm naval gun is arranged at the bow of the ship, with a range of 16km, a shooting height of 7000m and an emissivity of 45 rounds per minute.

Two duplex 40mm "mostly" short-range weapon systems, installed on both sides of the middle deck 02, are used for terminal defense, with a sea range of 12.5km, an air altitude of 4000m and an emissivity of 300 rounds per minute.

Two single-tube 20mm guns can be used for terminal defense.

In addition, there are electronic warfare systems of soft killing weapons, 2 concave tube jamming rockets of 105 mmsclare, and 2 "strange" jamming rockets.

(3) Anti-ship weapon system

The anti-ship weapon system consists of "Otto Matt" anti-ship missile, helicopter-borne anti-ship missile, 127mm naval gun, "Daduo" short-range weapon system and 20mm naval gun, which constitute nearly five kinds of firepower.

Four Otomart anti-ship missile launchers are arranged on the top platform of the hangar, two on one side, and the included angle with the center line plane is about 30.

The Otto Matt MK2 anti-ship missile is guided by active radar at the terminal of midcourse command guidance, with a range of 180kin. It is planned to replace MK2 with MK3 missile, and the range of MK2 will be increased to 300 kilometers. The terminal is guided by radar and infrared rays. When an over-the-horizon attack is carried out, a helicopter is used for relay guidance. It is reported that 1 AB2 12 helicopter can guide four missiles and attack four different targets.

AB2 12 helicopter carries MK2 Mars missile or Seagull missile. MK2 Mars missile is an all-weather airborne anti-ship missile, which mainly attacks destroyers, frigates and other medium-sized and below ships. The missile has a range of 20 kilometers and weighs 340 kilograms. Seagull missile has a range of 15km and a weight of 14-5kS. The AB2 12 helicopter can carry two MK2 Mars anti-ship missiles.

1 Otto Melara 127mm naval gun, with a sea range of 16km, is also the main weapon of "northwest wind" class fire support on the other side.

Two "Dado" short-range weapon systems are used to attack short-range light targets; Two single-tube 20 mm naval guns are used for maritime patrol.
