After all, the Haihongqi-61 is China's first-generation ship-to-air missile, which can only represent the technical level of the 1960s, and has many unsatisfactory technical performance: shorter range, slower response, and poor multi-target guided attack capability. The People's Navy in the process of modernization needs more modern ship-air missiles.

In fact, just before the 053H2G frigate was built in 1991, 051-type destroyer ("Brigade" class) in the "Kaifeng" has begun to add the introduction of the French "sea rattlesnake The "Kai Feng" in the People's Navy ("Brigade" class) had already been retrofitted with the "Sea Rattlesnake" anti-aircraft missile system introduced from France, as well as the supporting electronic fire control equipment, which proved the new generation of People's Navy's surface ships' air and naval missile technology in advance. 1994, a new destroyer with the port number of 112 was launched into the service in one of the shipyards in Dalian, and it was later known as the "first ship of the People's Republic of China". Type 052 destroyer ("Brigade Shanghai" class) "Harbin", the overall appearance of the former type 051 "Brigade" class a new look, catching up with the Western early 1980s level. The overall appearance is new compared to the former Type 051 "Brigade" class, catching up with the western level in early 1980s. Equipped with ship-air missiles, and three years ago, "Kaifeng" on the modified set of the same eight ship-air missile system; with automatic loading capability, radio command + photoelectric composite guidance; 26 prepared bombs, bullet length of 3 meters, bullet diameter 156 mm, wingspan of 0.55 meters, the combat part of the weight of 14 kilograms, the missile weight of 84.5 kilograms.

According to the Federation of American Scientists and the UK's Jane's Missile and Rocket Yearbook, the "Sea Red Flag"-7 technology first originated from France's Thomson CSF's fist product, the "Rattlesnake". - "Rattlesnake" (Crotale) air defense missile, in terms of performance belongs to a more advanced short-range ship-to-air missiles, in addition to strong air defense capabilities, anti-ship missiles also have a strong intercepting capability. The introduction and digestion of the latter, so that the domestic close-range missile system to say goodbye to the "Red Flag"-61 big and heavy old disadvantages, from the concept and technology have been greatly improved. Further development on the basis of the introduction of the "Red Flag"-7 missile system performance and reliability than the original system; maximum speed of Mach 2 3, shooting height of 15-5500 meters, the minimum range of 500 meters, the range of sea-skimming missiles for 8.5 kilometers, the range of 14 kilometers to the aircraft, the system's response time of 6-10 seconds, the probability of killing about 80%. probability is about 80%. Its outstanding close-range anti-missile capability is also far ahead of similar ship-to-air missiles in the world, so once equipped, it quickly replaced the Sea Red Flag-61 as the People's Navy's main point air defense missile.

From the Harbin's sister ship Qingdao (port number 113) to the Shenzhen (type 051B, port number 167), which began construction in Dalian in December 1995, the Chinese Navy has been able to develop a new generation of anti-aircraft missiles, including the Haihongqi-61, which is the world's leading anti-aircraft missile. The ship was built in December 1995 in Dalian, Shenzhen (Type 051B, port number 167, that is, "brigantine" class), and then in the late 1990s a large number of construction of the 052H2G2 frigate ("Jiangwei" II class), until the launch of the 054-type frigate in 2003, the Sea Red Flag a 7 basically all over the world. Subsequently, it also carried out deep technical excavation, launched an upgraded version of the FM-90N "flying midge" ship-to-air missiles: engine thrust is greater, faster, longer range, better maneuverability, better interception and anti-jamming capabilities, fire control system search, tracking distance increased to 25 and 20 kilometers; the maximum range of 15 kilometers, an increase of 25%, the minimum range of 700 meters accordingly; shooting height increased to 6,000 meters, the maximum overload of 35g, can intercept high-altitude incoming aircraft and missiles earlier; maximum speed of the missile 900 meters, seconds, more than 2.6 Mach. As a result of these improvements, the single-shot hit rate of the missile has increased to 80%. It should be emphasized that the FM190N missile has improved the ability to intercept ultra-low altitude targets flying at an altitude of 15 meters, and the new system adopts a dual-band radar, improves the TV tracking system, increases the laser tracker, and the detection capability and anti-jamming capability are far superior to the original version of the "Rattlesnake", which can provide effective low-altitude and ultra-low-altitude point defense protection for the naval surface ships. The Rattlesnake can provide effective low-altitude and ultra-low-altitude point defense protection for naval surface ships.
