U.S. Army tests long-range artillery shells with rocket engine

A U.S. defense contractor conducted field tests of a tactical engine to increase the range of artillery shells.

Despite the existence of missile UAVs and laser weapons, artillery remains the basis of support for ground troops.The main drawback of its weapons is the relatively small range of impact, due to the ballistic trajectory of the projectile after departure from the barrel.

To solve this problem, the U.S. Army has ordered Northrop Grumman to develop a special solid-fuel direct air-jet engine.

Engineered version of the Solid Fuel ramjetRamJet not only increases the flight range, but also improves the flight characteristics of the projectile, preventing it from slowing down due to air resistance. In addition, SFRJ allows you to correct its movement in flight, increasing accuracy, as well as the effectiveness of hitting a moving target.

The first tests were carried out on long-range 115-millimeter artillery shells.Tests confirmed that the technology is significantly expandingrange of U.S. field artillery on any terrain and in difficult weather conditions.

The U.S. Army Research Unit is also working on a prototype of a strategic artillery gun with a range of up to 1,850 km.
