The picture shows the POA-12 dual head bullet developed by Russia for the ASh-12 assault rifle. With the widespread use of drones in the military field, how to counter them has gradually become a research and development hotspot. In addition to emerging equipment such as laser weapons, microwave weapons, electronic jamming devices, and anti drone drones, there are also some modifications to traditional weapons such as machine guns and artillery in the current anti drone measures. The 7.62 × 54R dual warhead ammunition development plan proposed by a Russian military logistics academy is based on the modification of existing weapons and ammunition. It is said that the two warheads of this dual warhead ammunition adopt a serial design, with different shapes, masses, and functions. The first warhead is a conventional structure, while the second warhead is a tubular layout. When launched, the former has a faster speed and a longer strike distance, and is used to damage or destroy drones; The latter has a slower flight speed, protruding surface killing ability, and a closer strike distance. The combination of the two can improve the coverage range of single ammunition. If fired continuously, the firepower density will be further increased. The development of dual warhead and multi warhead ammunition is not an innovation of this military logistics academy. As early as the end of the 19th century, American ammunition manufacturers produced excessive bullet ammunition for revolvers and rifles. Afterwards, Italian researchers developed a multi bullet ammunition with a caliber of 6.5 × 52mm for the Carcano rifle. During the Cold War, American military personnel developed multiple rounds of ammunition for pistols, rifles, and machine guns, including both dual and triple head ammunition. However, due to poor performance, the US military ultimately did not purchase these ammunition on a large scale. In the 1980s, the Soviet Union began developing dual warhead ammunition with two calibers of 7.62 × 54mm and 12.7 × 108mm, but it was not put into mass production either. Until 2010, Russia underwent further research and development before equipping its military with dual warhead ammunition. Among them, the ASh-12 assault rifle can fire POA-12 double headed bullets. One of the benefits of this dual warhead ammunition compared to traditional single warhead ammunition is its high firepower density. Improving firepower density and strike power is also the original intention of the above-mentioned countries to carry out related research and development. Tests have shown that some dual warhead ammunition with a caliber of 12.7 × 108mm can increase the hit rate by 1.2 to 1.4 times compared to single warhead ammunition of the same caliber under certain conditions. Perhaps it is precisely because it can bring higher firepower density that this Russian military logistics academy came up with the idea of using this ammunition to counter the increasingly frequent and threatening use of drones. Generally speaking, efficient countermeasures against drones require many conditions. Two important points are: firstly, it is required that the weapons and equipment used for countermeasures are easy to carry and can be flexibly deployed and used; The second is to be economical and practical, especially in terms of manufacturing and usage costs, which should not be too high. Developing 7.62 × 54R dual warhead ammunition can precisely meet these two requirements. Firstly, 7.62 × 54R ammunition was introduced during the Soviet era, and one of the firearms it fired was the Mosin Nagan M1891 rifle. This increases the number of firearms that can fire ammunition of this caliber, such as PK/PKM machine guns, SVD sniper rifles, and some vehicle mounted parallel machine guns. Develop 7.62 × 54R dual warhead ammunition, which can be fired by many current firearms for flexible use. Secondly, some countries have developed mature bullet production lines centered around 7.62 × 54mm ammunition during the long-term manufacturing and use of this caliber. Developing dual warhead ammunition of the same specifications can fully utilize existing production lines to reduce manufacturing costs. However, whether this design can achieve the expected results still needs to be tested through practical experience. Previously, the dual warhead and multi warhead ammunition developed by relevant countries had some difficulty in ensuring accuracy when striking targets at longer distances. To meet the standards for countering drones, various issues such as reaction speed, shooting accuracy, and strike power must be addressed one by one. Only in this way can dual warhead ammunition become a new option for close range countermeasures against unmanned aerial vehicles, providing immediate anti drone capabilities for infantry teams, or a usable suppressive firearm ammunition for combat in urban environments.
