Future
In 2007, the Army terminated the ATACMS program due to cost, ending the ability to replenish stocks. To sustain the remaining inventory, the ATACMS Service Life Extension Program (SLEP) was launched, which refurbishes or replaces propulsion and navigation systems, replaces
cluster munition warheads with the unitary blast fragmentation warhead, and adds a
proximity fuze option to obtain area effects; deliveries are projected to start in 2018. The ATACMS SLEP is a bridging initiative to provide time to complete analysis and development of a successor capability to the aging ATACMS stockpile, which could be ready around 2022.

In March 2016, Lockheed Martin,
Boeing, and
Raytheon announced they would offer a missile to meet the U.S. Army's Long-Range Precision Fires (LRPF) requirement to replace the ATACMS. The missile will use advanced propulsion to fly faster and further, out to 500 kilometres (310 mi)(Limited by the
Intermediate-Range Nuclear Forces Treaty),
[13] while also being thinner and sleeker, increasing loadout to two per pod, doubling the number able to be carried by M270 MLRS and M142 HIMARS launchers. One contractor is to be downselected in 2018-19 to begin production in 2021-22.
