It seems like the whole point there is to be expeditionary. A mortar in an LAV isn't going to get airlifted in a helicopter.
That's the party line but it does not pass the sniff test. Moving tubes by vertical lift obligates one to supply the ammo by the same means indefinitely (not to mention fuel, water, food, and infantry to defend the guns). Emplacing guns or mortars by helicopter is a raid tactic. If we can land them via helicopter within range of the target perhaps we could get an LZ close enough to use 81s instead of 120s and forget about air transport of that POS jeep which will not pull itself or the mortar through a mud puddle.
Hilltop firebases are not a tactic that achieved anything of operational significance for us in Vietnam and it should be shocking that a towed ground fire support system is designed with heliborne or Osprey-internal insertion as a KPP. The Osprey mafia imposed the same idiocy on the LW155 howitzer (M777) in stipulating that it had to weigh less than 9000 pounds so that it could be sling loaded under and Osprey. Why the hell would you ever want to do that? Putting a $3 million gun under a $78 million aircraft is STUPID on the face of it not to mention that another bird has to carry the crew and ammo. There was not even any pretense of airlifting a truck to pull the LW155 after it was emplaced by the Osprey.
If we can get and Osprey to deposit a mortar battery at a support by fire position without getting its $78 million airframe shot down could we not risk fewer lives and just put a Harvest Hawk or better yet a Spectre up there to shoot from the air? A surface fire support system justifies itself by being able to shoot when and where an aircraft cannot and answering calls for close support more quickly. You can't pretend or contrive a situation in which a mortar (or howitzer) emplaced by vertical lift can perform a fire mission that an assault aircraft could not.
I am a big believer in all weather surface fire support but the EFSS can't provide that without trains that make it look like a 155mm battery. If the weather is too inclement to fly ground attack aircraft it is probably also going to adversely impact any fin-stabilized mortar round as well to the point that accuracy will be seriously degraded. Forgetting for a moment how you get the tube into position, a spin stabilized 105mm howitzer can pump out rounds faster and farther than a mortar with a much lower CEP when there is significant wind. Besides which, that mortar battery is not going to by flying its own MET balloons to correct for the meteorological conditions.
If a heavy mortar was the pre-ordained solution for the EFSS capability a rifled (spin stabilized) mortar mounted on a LAV or other rolling chassis would have overcome the problem of rapid emplacement and displacement after firing that is so important with a high angle weapon when there is a counterfire threat. It would also have less drift than the fin stabilized projo.
I really like mortars. They are great fire support tools when employed correctly and not given tasks that should be assigned to howitzers. We got sold a bill of goods with the EFSS.
