Well, from this site: http://nextbigfuture.com/2011/04/railgun-roadmap-review.html
And this report: https://www.navalengineers.org/SiteCollectionDocuments/2009%20Proceedings%20Documents/AD%202009/Papers/Ziv_Johnson.pdf

Benefits of the EMRG include enabling maneuver forces to move quickly to their objectives
ashore with a reduced logistical tail and improving end-to-end logistics made possible by the use
of non-explosive projectiles. Recent history has shown that explosives significantly complicate
sustained and stability operations. Additionally EMRG provides operational support for dangerclose
and terrain masked targeting.
quote:
The anticipated range of the EMRG at 64 MJ (222 NM) exceeds the anticipated range of all
current or near-term projectiles including the Long Range Land Attack Projectile (LRLAP) and
supports the future assault range of the US Marine Corps (USMC) MV-22. (See Figure 4.) This
capability will allow the EMRG to complement USMC MV-22 tactical air assets in high
operational tempo engagements and may be used to provide support to forces ashore when
operational or environmental conditions do not permit the flow of air power to the target
location. Even at 32 MJ (half the full tactical energy level), the EMRG will have an anticipated
range of approximately 110 NM, whichisequaltothecurrentUSMC“ship-to-objective
maneuver”(STOM)distanceof200km(about110NM).
quote:
The EMRG will provide Joint Forces a unique capability for volume fire at long range, enabling
rapid engagement of a wide variety of targets including stationary structures, such as buildings
and bridges, and relocatable targets, such as surface-to-air missiles for Suppression of Enemy Air
Defense (SEAD) (Pifer et al. 2007). Current weapon systems, such as tactical aircraft (TACAIR)
or cruise missiles, have comparable or greater ranges than a 64-MJ EMRG projectile at
significantly greater costs, but cannot provide an equivalent volume of fires. Other Naval guns
can provide volume of fires, but at significantly shorter ranges. The EMRG provides a truly
unique capability for volume fire at long range and an ability to engage targets in a high-threat
environment. The use of the EMRG enables rapid engagement of a wide range of target sets,
while freeing up TACAIR and cruise missiles to concentrate on high-value targets that are not
likely to be engaged effectively with first-generation EMRG weapon systems.
quote:
Finally, the high-altitude flight profile and steep attack angle of EMRG projectiles provide
greater flexibility to attack targets effectively in mountainous terrain by using projectiles that are
practically invulnerable to enemy counterattack. It is impractical for the enemy to engage EMRG
projectiles as they descend into the target area. Theprojectile’ssmall size and extremely high
velocity present a very difficult target and an unfavorable geometry to enemy defensive systems.
In addition, the large number of EMRG projectiles will likely overcome any enemy defensive
system. Future EMRG system development could enable an unprecedented capability to place
rounds in a pre-determined pattern to dramatically increase target lethality over a wide range of
potential threats.
There's some specifics on operational scenarios for the system, not sure if it warrants a new entry in the DB though yet.
