Increment 1 is 550km
Increment 2 will add an antiship seeker
Increment 3 will increase the range to 800-1000km
PrSM Increment 1: range >500 km
PrSM Increment 2: multi-mode anti-ship seeker and will be known as Land-Based Anti-Ship Missile (LBASM)
PrSM Increment 3: integration of new payloads
PrSM Increment 4: double the target range of Increment 1- >1,000 km called Long Range Missile Maneuverable Fires (LRMF)
The development program carries a new name, the Long Range Maneuverable Fires missile, and includes a new form factor and propulsion system.

The US Army is very committed to increasing the range of its offensive actions, which is currently limited to 300 km from the ATACMS and a similar distance if using the Apache.
The USA is seeking to increase the range of 155mm artillery to 70km and will introduce a GMLRS guided “rocket” with a 200km range. Today the GMLRS is limited to 80 km.
It will also introduce the PrSM to replace the ATACMS which will have at least 500 km but with a version with terminal guidance and extended range (700 km) and an elongated version with >1000 km of range in mind.
The Tomahawk Block V (1800/2000 km) and the Block IB version of the SM-6, a hypersonic with at least 1000 km of range against targets on the ground, will also operate truck-launched.
A DARPA advanced missile program, OpFire, could result in a hypersonic missile with up to 2000 km range.
And here comes the LRHW with a range that can reach 4000 km.
The list is long:
GMLRS-ER: 200 km range
PrSM: 500/700 km range
PrSM-ER: 1000 km
OpFires: 1500/2000 km
SM-6 Block IB: 1000 km
Tomahawk Block V: 1800 km
LRHW: 3000/4000km
