If the 'Wild Bee' UAV swarm attack system developed by the Equipment Research Institute is used at the campaign or battlefield strike level.

Then Wu Hao's 'Battlefield Sweeper' developed by them alone is used in small-scale battles. The two are not the same for the purpose, and the cost is also very different.

Although the core technology relies on cluster control technology, there are also big differences between the two.

First of all, the 'Wild Bee' UAV swarm attack system, which covers a wider range of airspace and has a larger swarm, is less affected by the subtle terrain.

In terms of offensive methods, it is also more direct and straightforward. Discover the target, destroy the target, if one doesn't work, then a few more, anyway, it's not a problem for a huge cluster.

This is not the case for this kind of 'battlefield sweeper' who responds to small-scale battlefields and battles, because the use environment and users are different, so the cluster of such small drones cannot be too large.

Moreover, because of the relatively small size of this small high-speed drone, the endurance time is very limited, generally only about ten minutes.

This limits the number of aircraft in the fleet and the range covered, so ideally, this kind of small high-speed UAV strike group is generally about two to one hundred aircraft.

Below this number, there is another single small attack drone. For example, in the military movie we released earlier, the special operators used small drones to attack the enemy's mortar positions.

In fact, to put it bluntly, it is a small drone equipped with a grenade. It can attack any target within a one-kilometer radius under the user's control.

This distance is already the range of mortar rocket barrels, and far exceeds the effective range of some grenades and rifles.

What's more, it can be controlled at will. In other words, it can attack those who want to attack under human control, just like missiles.

Moreover, the flight speed of nearly 300 kilometers per hour makes it difficult for it to be intercepted by the enemy.

Therefore, this small high-speed attack drone has also become an important firepower strike weapon in the special operations of various countries, and it has also become a sharp weapon for anti-sniper and anti-guerrilla team attacks.

Of course, this small drone is not without its weaknesses. Endurance period, light weight, less ammunition and limited power are his weaknesses. And the control and hands-on ability requirements are relatively high, and the operator needs to practice many times to adapt.

There are more than that, and that is large swarm attack drones. The tasks undertaken have also reached the stage of striking key targets on the battlefield, in battles, and even at the strategic level, and are controlled by professional troops.

In fact, to put it bluntly, it is to gather many small high-speed attack drones to form a small-scale battlefield strike group to deal with the enemy's small-scale living forces.

Compared with the kind of small high-speed attack drones that need to be controlled by special personnel, this battlefield sweeper only needs the user to launch, set the corresponding reconnaissance and strike area, and let it go after launching, and the small high-speed attack drone cluster will automatically search for and attack enemy targets in the set area.

In addition, the drone can also be equipped with friend or foe identification technology. On a battlefield where we are mixed with friends and enemies, we can automatically identify our and enemy targets and carry out selective attacks.

For example, let's say our convoy or combat squad is ambushed by the enemy. Normally, in this environment, it is difficult for our counterattack to be launched, and this is when the battlefield sweeper can play its role. Our personnel only need to hide in bunkers and fly these small high-speed attack drones, and then they can search for enemy personnel targets in a demarcated area.

Although the individual power of this small, high-speed drone is relatively small, it is attacking enemy personnel. If the accuracy is high enough, it can even explode close to the enemy's most vulnerable areas such as the face, neck, crotch, etc., to kill or inflict on the enemy.

In fact, in the current combat concept, there is no longer a requirement for individual firepower equipment to be powerful, whether it is a grenade or a grenade, the charge has been reduced.

It can be clearly seen from some data that the charge of grenades in World War II was basically more than 100 grams, and now the charge of grenades equipped by various countries is about 50 or 60 grams, which has more than doubled.

In addition to being easy to carry and carrying more quantities, it is also to be able to kill and damage enemies as much as possible. Because in combat, killing and wounding an enemy is more effective than killing an enemy.

Although their 'battlefield sweeper' is relatively small, a single attack drone is also relatively small. However, compared to the 'Wild Bee' drone swarm attack system, this 'Battlefield Sweeper' is more difficult.

The difficulty of the 'Wild Bee' UAV swarm attack system lies in the control and management of large UAV swarms, while theirs, the battlefield sweeper, lies in the timely capture and processing of information.

First of all, the first problem is how to maintain normal high-speed flight in complex terrain, such as jungles, cities, ruins, etc., in complex terrain and other environments, so as to avoid hitting obstacles.

In the environment here, there are many and complex obstacles, and how small high-speed attack drones can travel freely and at high speed without being affected requires special technology to solve them.

In the racing of the traverser, it is controlled by the competitors wearing special first-view video glasses. The speed of the traverser and the smoothness of the obstacle crossing are entirely dependent on the individual reaction control of the operator.

Even experienced and skilled players often get "blown up" (Note 1) in complex environments.

Therefore, to overcome this problem, it is necessary for the drone to detect the surrounding environment and obstacles at all times, and autonomously and quickly plan a feasible flight path.

The best solution is to install relevant sensors for the drone, such as distance sensors, radar, image sensors and other hardware devices, so that the drone can detect surrounding obstacles.

It's not enough to just find these obstacles, you also need to do a quick computation. This requires software optimization, and it is not enough to process this information correctly, it must be processed quickly or even in real time. If the processing speed cannot keep up with the flight speed of the drone, then the information obtained will not be timely and lead to the explosion of the aircraft.

This is only a problem in flight, small high-speed attack UAV to achieve autonomous combat, then it must find the target, and how to find the target is also a problem that needs to be solved urgently.

Often, this kind of target discovery work or task is determined by people. But now it is up to the drone to solve it by itself, which is undoubtedly a lot more difficult.

[Note 1: Fri-up aircraft, a term for model airplanes.] Generally speaking, due to improper operation or machine failure and other factors, the flight model aircraft crashes abnormally to the ground is called a bombing plane. 】
