The development of the elements that will infiltrate behind the front and hunt the field artillery and the increase in air support costs encourage countries to develop longer-range artillery systems.

The U.S. made a $ 33 million deal with BAE Systems for the new long-range artillery system. In this context, the company will manufacture LR-PGK (Long Range Precision Guidance Kit) for 155 mm artillery rounds. The system, which is stated to be critical for the Army's long-range artillery program, enables high-precision shooting at long range. It is stated that LR-PGK is a cost-effective solution for the long-range artillery requirement for the artillery field, one of the force's top priority modernization programs. The system, which has a GPS based, anti-jamming environment friendly navigation system, makes flight corrections with a very low CEP value by making flight corrections with the roll-stabilization system, antenna array and canard control.

The US, which has M109 self-propelled and M777 towed howitzer, with a barrelled artillery system equipped with 39 calibre barrels that can shoot at the longest range for a long time, has launched the ERCA (Extended Range Cannon Artillery) Program in recent years. In this context, a 155 mm 58 calibre barrel was integrated into a carrier platform adapted on the M109 chassis and accurate shots were fired at a range of 65 kilometres.
