Spain is presently utilizing about 95 M109A5E caterpillars, which, due to their tactical and method parameters and service time, are already obsolete. Therefore, it is planned to acquisition a fresh artillery on track and wheel traction. In total, Madrid plans to get 145 cannonohabic, of which 36 on a wheel chassis, and 109 on caterpillars. However, according to the Spanish Infodefensa service, these figures may change. According to the assumptions, the fresh artillery is to have a barrel of coal. 155 mm with a dimension of 47-52 calibers with a burden capacity exceeding 40 km in the case of the usage of gas-generator ammunition. Thus, the fresh construction will importantly increase the firepower of Spanish artillerymen presently able to mark at a distance of up to 30 km utilizing M109.
