In the final phase, the army sees the technology that is delivered to the large defense contractors. The new projectiles would be a "component technology provider for the weapons systems integrator industry (for example, Raytheon Missile Systems, Lockheed-Martin Missiles and Fire Control, Orbital ATK) for these new control technologies in future weapon systems. (for example, High Explosive Guided Mortar) ".
The United States Army wants bullets and mortar shells that do more than hit a target. He wants projectiles that can hit a moving tank or even an airplane in flight.
(This appeared for the first time several months ago.)
It's a good idea, except there's a problem. Constructing small projectiles with actuators (the mechanical parts and control surfaces that would adjust the trajectory of the projectile) that can survive being fired with a gun is a challenge.
It is not that the guided projectiles do not exist. The problem is that they are only for artillery. Approximately a decade ago guided projectiles arrived like the M982 of the Army of the United States. Excalibur, configured with fins and GPS guidance to adjust its trajectory in flight, reliably lands much closer to the target than normal projectiles. But even these projectiles, fired indirectly from miles away, are really suitable for hitting fixed targets. According to the army, normal artillery shells have a landing accuracy about 650 feet from the target. The M1156 guide kit, which can be adjusted to convert normal housings into intelligent housings, has an accuracy of 165 feet, while even an Excalibur shell still has an accuracy of sixty-five feet of the target.

But a new army. investigation project It aims to create small projectiles (bullets, mortar shells, hand rockets) that can change their trajectory in the middle of the flight. "The current technologies of guided munitions launched with a gun are limited to indirect fire against stationary targets on the ground," says the army. But a more maneuverable projectile, better able to adjust its trajectory, could offer numerous benefits, such as "extreme range extension, improved maneuvering authority that allows intercepting mobile targets on land and air, and a greater conformation of trajectory that could be used to change the mean course of the projectile's path or control the terminal approach angle to maximize lethality. "
For example, a bullet that can change its trajectory could scale a wall and hit the target behind it. A mortar shell could change its trajectory so that it hits the ground at the most lethal angle.
But, of course, it could not be that easy. The problem is to build a casing with actuators, the mechanical parts that allow the casing to change its trajectory, strong enough to survive being fired from a cannon. "The gun-throwing event imposes severely high structural loads as the projectile accelerates from a stationary speed to a snout that exceeds four times the speed of sound," the military says. Some actuators can survive being thrown from artillery pieces that impart a force of 20,000 times the force of gravity. But direct firearms can impose greater tensions: the electromagnetic. gunboats that the US military is developing, for example, imparts a force of 60,000 times gravity.
The military suspects that the answer lies in "innovative solutions in electromechanical design, power conditioning, feedback detection, integrated processing and control algorithms". The first phase of the project requires thinking about ways to develop ways to control the trajectory of small projectiles, followed by a prototype.
In the final phase, the army sees the technology that is delivered to the large defense contractors. The new projectiles would be a "component technology provider for the weapons systems integrator industry (for example, Raytheon Missile Systems, Lockheed-Martin Missiles and Fire Control, Orbital ATK) for these novel control technologies in future weapon systems. (for example, High Explosive Guided Mortar) ".
