Your ‘proposal’ if you can call it that fails to take into account so many issues it is ridiculous. Something you thought about for five minutes isn’t a serious proposal to change the Army’s structure. First of all 10 M777s don’t have the fire power of 4 SPGs like K9 or PzH2000. They can shoot further, faster and from a bigger unit of fire. Also 10 M777s require 70 Gunners to crew rather than 16-20 (4 SPGs) and combined with their gun tractors would match the maintenance needs of 4 SPGs.Do 4 SPGs really have more firepower than 10 M777s because that is the substitution my proposal would make?
Also the Army just doesn’t need 45 more 155mm guns unless we were to reequip the reserve units. Army has 35 M777s and 36 M198s which have been upgraded and are still excellent weapons. 24 155mm guns per brigade is what you would need for high intensity combat which is not a requirement of the Army. We would need many more tanks and IFVs and the like to build units needing high levels of artillery.
Ahh yes and has maintained them since WWII and used them in combat in VietNam, Somalia, East Timor, Iraq and Afghanistan.Do Does the Australian Army need the ability to have a fully mechanised battlegroup?
Well you don’t know much about MEUs. They have plenty of armour and used to have M109s until they were cut for funding reasons in the 1990s.For Australia's needs isn't the ability to put a USMC MEU type unit into the field more relevant. I just don't think a SPG is needed for that or worth the effort for our Army.
Armour is needed for force protection. The biggest difference between a SPG and M777 is the former can keep firing in the face of enemy fires. Well the M777 can but it would cost casualties amongst our Gunners. This is the thing the Armchair Generals don’t understand about the Hardened Army; it’s all about force protection not about building forces for fighting mass tank battles and the like. You can take the armour out of the Army to meet silly political and perception issues and that will just cost lives amongst our soldiers.
Sure but this is not a problem specific to SPGs but just the Army. Army could acquire M109A6s off the shelf integrated with AFATDS if they wanted an OTS solution.That's another problem with the SPGs. Rather than just buying them Army has a whole series of unique requirements which mean delay, development risk and increased cost. The Towed guns are the low risk option. They could be ordered and in service before a decision is even made on the SPG.
