US Army Looking to More Than Double Range of 155mm Howitzers

On March 19, U.S. Marine Corps staff sergeant Louis Cardin, a field artilleryman assigned to the 26th Marine Expeditionary Unit, died during an attack on Fire Base Bell outside of Makhmur, Iraq. Coincidentally, the U.S. Army is hard at work developing a farther-firing howitzer that could help keep artillery troops out of range of enemy forces.

The Army is cooking up a suite of improvements could double the range of the existing M-777 howitzer. Right now the 155-millimeter gun, in service with the Army and Marines, can lob shells at targets up to 18 miles away.


The modifications add fewer than 1,000 pounds of extra weight onto the older howitzers. The updates include improvements that will help gunners fire more accurately plus a mechanism to automatically load rounds into the gun.

The biggest change is the addition of new barrel that’s six feet longer. The longer M-777ER should be able to hit enemy forces more than 43 miles away. And with more powerful propellant charges and rocket-assisted shells, crews might be able to increase that range even more in the near future.
