Self-propelled artillery remains important in the equipment of many modern armies. It saw a significant role throughout the [[Cold War]] era conflicts and in the 1991 [[Gulf War]].

Modern SP artillery is highly computerized, with the ability to self-survey firing positions using systems such as [[Global Positioning System|GPS]] and [[inertial navigation system]]s. This, in conjunction with digital [[Fire control system|fire control]]/ballistic computers and digital communications, allows individual guns to disperse over a wide area and still [[Time On Target|deliver rounds on target simultaneously]] with the other guns in their battery.

These capabilities also increase survivability manyfold as modern SP artillery can displace and avoid [[counterbattery fire]] much more quickly and effectively and, if desired, more frequently than previously possible. In conjunction with modern logistic systems (where the SP gun's systems can track and report on ammunition consumption and levels) with similar navigation systems and [[463L master pallet|palletized]] [[Air drop|load dropping]]/[[Air lift|lifting capabilities]] mean that the rapid displacement can occur without significant disruption to actually firing missions as it is possible for the ammunition to keep up with the guns.

A modern battery of six guns, each firing 43&nbsp;kg projectiles with a burst [[Rate of fire|firing speed]] of four rounds per minute, can deliver over a [[tonne]] of ordnance per minute for up to four minutes. This is an immense [[weight of fire]], which can be delivered with very high accuracy.

One example of the increased firepower provided by modern mobile howitzers is the latest version of the 155&nbsp;mm [[G6 howitzer]], the G6-52. It can fire up to six rounds in quick succession that will land nearly simultaneously. This is achieved by firing the shells at different trajectories so that the first round has the longest flight time and the last round the shortest. This is an improvement of the concept of [[Artillery#Multiple round simultaneous impact|multiple-round simultaneous impact]] (MRSI), itself an enhancement of the earlier TOT ([[time on target]]) concept. The necessary rapid reloading is made possible by an automated ammunition feed system.{{citation needed|date=January 2024}}
