recently, the navy's 051b "shenzhen" ship has arrived at the shekou cruise home port in nanshan district, shenzhen city. people can board the ship and visit some areas on the ship for free through relevant mini programs. many people are extremely affectionate towards this legendary battleship. since the ship was launched in october 1997, it has been given high expectations because it is china's first independently designed medium and large guided missile destroyer, which was still at an advanced level at the time. although many people said that the haihongqi-7 air defense missile carried by the ship at the time only had "point air defense" capabilities and did not have the "regional air defense" capabilities that had been born and popular at that time, but from the perspective of "hindsight", at that time, neither the russian navy's 1144 "kirov"-class nuclear-powered cruisers nor the us military's ticonderoga-class guided-missile cruisers had reliable regional air defense capabilities.

the air defense system used by the 1144 cruiser is mainly the same "top cover" radar as the 1164 "glory" class cruiser to provide fire control illumination (one ship has a "tombstone" radar). like the glorious-class cruiser, the kirov-class cruiser also has a multi-layered air defense network. however, combined with the sinking of the glorious-class cruiser "moscow" by a high-subsonic anti-ship missile in the black sea, it can be proved that the regional air defense system of that era was not yet mature, whether it is the soviet union's 5v55 (sea-based version of s-300) or the american standard 2 series, this is true, and even the people's liberation army's haihongqi 9 is no exception. for this reason, ship air defense in the 1990s was dominated by point air defense systems. even on the ford-class aircraft carriers built in recent years, the us military still installed the "sea sparrow" point air defense system to provide the last layer of security for the aircraft carrier.

for this reason, in an era when point air defense was relied upon to shoulder heavy responsibilities, this shortcoming of the 167th ship was not obvious. after modification, its firepower became even more powerful. taking this open exhibition as an example, ship 167 is rarely fully equipped with 16 yj-12a heavy-duty supersonic anti-ship missiles with a range of 500 kilometers. such a state can be described as extraordinary strength for the shenzhen ship. the anti-ship missile currently used by the u.s. navy's burke-class destroyers is the harpoon subsonic anti-ship missile with a range of 180 to 220 kilometers. it is expected to be replaced with the nsm subsonic anti-ship missile with a range of 180 to 260 kilometers. although the lrasm with a range of more than 900 kilometers is better, it is difficult for the us military to fully replace it because of its high unit price. for this reason, there is no pressure for the shenzhen ship to duel with the burke class. judging from the strike characteristics of the eagle strike 12a, it is characterized by its high speed, exceeding 3.5 times the speed of sound. it is powerful, with a semi-armor-piercing warhead containing more than 300 kilograms of explosives. the guidance and strike system is mature, with active radar guidance at the end and a phased array seeker, which has high accuracy and strong anti-interference ability.

since the size and weight of the yj-12a cannot be adapted to the vertical launch system, its future prospect is to replace the existing yj-83 series tilt-launch missiles. in addition to the shenzhen ship that has been equipped with this missile, the modified modern the same is true for class destroyers. even the foreign trade 054a/p frigates use the foreign trade version of the yj-12a missile. what is incredible is that the new batch of 054a frigates and 054b frigates have not been refitted. it is speculated that the number of yj-83s is too large and they cannot be fully refitted.
