British BAE Systems has developed a modernization program for self-propelled guns M109A7 called ERCA (Extended Range Canon Artillery, long-range cannon artillery). During the implementation of this program, howitzers will be subjected to modifications., designed to increase the firing range and rate of fire.

reportedly, the turret will be slightly changed on the upgraded vehicles, and on the gun a standard caliber barrel 155 millimeters long 39 calibers will be replaced with a barrel length 58 calibres (8,9 m). This replacement will increase the firing range from 30 to 70 kilometers.

The company suggests, that as a result of the modernization of the gun part, the mass of the self-propelled howitzer will not change, and this will save you from expensive modifications to the chassis of the self-propelled howitzer.

The program provides for the creation of a prototype of the improved M109A7 howitzer and comprehensive testing., based on the results of which a decision will be made to modernize the rest of the howitzers fleet, in service with the US Army.

Self-propelled howitzer M109A7 is a modification of the self-propelled howitzer M109A6 Paladin. As a result of the modernization of the M109A, the internal space was increased., reduced weight and cooling capacity.
