Dave sorry it's a bit of a novel, but this is from a US defence site. The only thing not mentioned here is the fact that the Aussie M1A1s will run on diesel not JP8 jet fuel.
The Abrams Integrated Management (AIM) Overhaul Program is an innovative teaming of the prime contractor, GDLS, and Anniston Army Depot (ANAD) to refurbish the tank to a like-new condition. The AIM Overhaul is the Army's under-funded program to sustain the nearly 7,000 Abrams Tanks as part of the total recapitalization plan. AIM is funded at 135 tanks per year which translates into a 12-year rebuild cycle for the active component. As the M1A2 fleet ages, the Army must expand AIM to include about 90 M1A2 SEPs per year beginning in 2012. With a 20-year rebuild cycle for the reserve component, the Army must implement a 90 tank per year program beginning in 2006.
AIM alone is a sustainment process only and does not insert new technologies nor address obsolescence. However, by exploiting the synergy created by integrating the AIM program with a viable Abrams recapitalization program, the Army has a cost-effective opportunity to apply and field these high-payoff projects. The current high-payoff projects include 2nd Generation FLIR, frontal & side armor upgrades, Vehicle Integrated Defense System (VIDS), digital turret & hull networks boxes with built-in test, and a new engine.The AIM Overhaul program is the optimum time/location to complete applied improvements. The AIM Overhaul program in its objective state will produce M1A1Ds. Currently the process applies many product improvements with some M1A1s receiving the M1A1D configuration retrofitted in the field.
John you see you should never have opened your mouth because now I have to see your Abrams.
Jules it was great to have have a chat in person mate.
Cheers
