For example, when the anti-ship missile warhead is adopted to strike large ships such as a destroyer, the deck and cabin structures of the large ships adopt thick high-strength alloy steel and stiffened plate structures, so that the anti-ship missile warhead has strong damage resistance correspondingly, and holes with certain calibers are formed or a certain amount of impact is provided at the initial stage of penetration when the targets are struck, so that the penetration of the warhead to the targets or targets at subsequent layers is facilitated, and the convenience is brought to the design of penetration of the warhead in a limited space, so that the fighting efficiency is improved, and the purpose of high-efficiency damage is achieved.

Therefore, it is generally considered to add a device for opening holes, such as an explosive shaped projectile (EFP) forepart and an annular jet forepart, to the front end of the anti-ship missile warhead. Thereby, a series warhead is formed; when the series warhead touches the target, the hole-opening device at the front end performs hole opening, and the subsequent warhead along with the warhead enters the target by utilizing the opened hole to damage the target. However, in order to achieve the purpose of improving the loading capacity of the warhead and the stability of the loaded powder in the penetration process in a limited space, the application of the multistage warhead occupies a large amount of axial space of the warhead, so that the length-diameter ratio design and the loading capacity design of the penetration warhead are limited in the limited space, and the penetration and the efficient damage of the warhead to the subsequent layer of expelling warship cabins are not facilitated.

The other means of perforating and filling is to add a filling device with the function of perforating and filling on the head of the warhead, and the device performs perforating and filling on the target in the initial stage of penetration, so that the stress of the subsequent penetration warhead projectile body is reduced, and the length-diameter ratio and the dosage design of the warhead are facilitated. The device does not occupy the limited design space of the warhead, and is beneficial to the penetration of the subsequent target plate and the damage of the warhead, so that the device has advantages in hitting large-scale ship targets such as a destroyer.
