HQ-61C - Navy Development
Further research and development of HQ-61B continued even after it was formalized in 1988. The missile was improved based on the technology of Aspide AAM purchased from Italy, and the design of the launcher was also changed. The twin launcher mounted on the "Yingtan" is inferior in responsiveness because it takes out the missile from the ammunition storage and reloads it every time it fires, and the missile is attached to the launcher in its original state, so it is outside. It had the problem of being easily affected by changes in temperature and deterioration of the weather.In order to improve these points, a new 6-unit launcher (formal name is "H / EFB02 box launcher") was developed. The H / EFB02 6-unit launcher houses the missile in a canister that is not easily affected by climate and temperature, improving responsiveness and maintainability. However, because the wings of the HQ-61 missile body are not foldable, the canister that houses the missile has become quite large for a short SAM. The HQ-61B (sometimes called the HQ-61M) that received these improvements was installed in the 053H2G frigate (Jiangwei I / Jiangwei I), which was commissioned by the first ship in 1991.
Six missiles are stored in the canister of the launcher. However, the ammunition depot in "Yingtan" has disappeared, and there was a lack of continuous combat capability. The HQ-61 missile weighs more than 300 kg, and the combined canisters weigh more than 350 kg. With this weight, it was difficult to reload manually, and it was virtually impossible to reload the missile at sea without equipment such as a crane on the 053H2G type frigate (Jiangwei type I / Jiangwei type I).
The anti-aircraft search radar of "Yingtan" was changed from the 381 type three-dimensional anti-aircraft search radar to the long-range anti-aircraft radar 517H-1 type (Knife Rest) and the anti-aircraft anti-water radar 360S type (SR-60). In addition, the illuminator and target tracking radar is equipped with the same type 342 control radar as the "Takatan", but since the number of installed missiles is one, the number of missiles that can be guided at the same time is two to one of the "Takatan". It decreased to, and it became impossible to track other targets while the missile was being guided.
Under the final development type HQ-61C, four 053H2G frigate (Jiangwei I type / Jiangwei I type) were built, but the performance of the HQ-61M did not satisfy the Chinese Navy. In response to this, the development team decided to start the development of the HQ-61C, which is a further development of the HQ-61B/M.
The HQ-61C reviewed the layout of the missile's stabilizer and control wings and adopted the same "XX" -shaped layout as the US Sea Sparrow. This was intended to improve missile control and aerodynamic refinement, and with this modification the HQ-61C was able to withstand a maximum load of 25G and succeeded in improving the interception capability of ship-to-ship missiles. To improve the short range, the rocket motor has undergone a complete design change, with a maximum range of 10km to 15km and a maximum range of 8,000m to 12,000m, expanding the air defense area by more than 40%. Achieved improved performance . Improvements were also made to the control system, improving detection and tracking capabilities, improving electronic jamming and detection capabilities from low-altitude clutter, and strengthening the ability to respond to anti-ship missiles flying from low altitudes. Overall, the HQ-61C is rated for performance close to that of the US RIM-7H "Sea Sparrow," but the problem with large canisters due to its lack of a wing folding mechanism remained unsolved.
Finally, the improved version of the 053H2G frigate (Jiangwei II / Jiangwei II) is a HHQ-7 ship-to- air missile that imitates and domestically produces the French Crotal ship- to- air missile instead of the HQ-16C as a ship-to- air missile. Adopted a missile . Since then, no ships equipped with the HQ-61 series have appeared. Therefore, the HQ-61B / M was installed on the 053K type frigate (Koto type) No. 1 ship # 531 "Yingtan" and the 053H2G type frigate (Jiangwei I type / Jiangwei I type).
The HQ-61C finished development without a ship on board. The reason why the HQ-61B / M's unit deployment was limited is that the technology level is old and the range is short, the launcher is larger than the HHQ-7 and the missile load is inferior, the HHQ-7's It is mentioned that the production cost is lower, the technical level and performance are superior, and the operation is easier. In addition, the weight of the HHQ-7 missile was 100 kg or less, and the ability to manually reload the missile even at sea greatly increased the continuous anti-aircraft combat capability compared to the HQ-61. It seems that the deciding factor for rejection was that the above problems could not be solved even with the improved HQ-61C.
