Ramjet-powered artillery shell sets new range record at 150 Km. Precision guidance next

Since we are living in dangerous times with potentially escalating military conflicts!

This new artillery shell was tested in my home state Arizona at the Army's Yuma Proving Ground (near Mexican border) about 200 miles from my home. Hope, they don't extend the range too much further. 😊

"... To overcome this, Boeing and Norway-based Nammo have partnered under the US Army’s XM1155 program to develop a new class of extremely long range artillery that uses advanced ramjet technology, yet can be fired by standard guns without modification. ...
Where the fuse goes on a conventional shell, the Boeing/Nammo shell has an air intake with an aerospike projecting from it. Inside, the body of the shell is lined with solid rocket fuel that takes up little space because there's no oxidizer in the mix. When the shell is fired, it quickly accelerates to supersonic speeds, where the ramjet kicks in. The air in front of the shell is scooped in, compressed, mixed with the fuel, and burns, generating thrust.

The upshot of this is that the 155-mm shell increases the range from about 14 miles (22 km) to 93 miles (150 km). ..."

"... In an upcoming test, Boeing and Nammo will integrate a precision guidance system, leveraging a Joint Direct Attack Munition (JDAM) mission computer onto the Ramjet 155. The demonstration will evaluate the system’s maturity and effectiveness against stationary and moving targets, and readiness to transition into the next phase of development. ..."

Ramjet-powered artillery shell sets new range record Boeing and defense company Nammo partnering with the US Army have set a new range record during an indirect fire test of a ramjet-powered artillery shell when a Ramjet 155-mm round was fired from a 58-caliber Extended Range Cannon Artillery (ERCA).
