Abrams M-1A1 AIM

976

The AIM process is a joint effort to refurbish M1A1 Abrams main battle tanks and involves the U.S. Army Project Manager for Heavy Brigade Combat Team, TACOM Life Cycle Management Command, Anniston (Ala.) Army Depot and General Dynamics Land Systems. Under the AIM process, M1A1 Abrams tanks are completely disassembled and overhauled to a like-new, zero-mile condition. Refurbished tanks incur lower operational and support costs and report higher operational readiness rates.

The M1A1 AIM tanks will be configured with additional mission-critical technologies to bolster crew situational awareness (SA). The SA package improvements include second-generation Forward-Looking Infrared, Far Target Locate, Blue Force Tracking (BFT)/Force Battle Command Brigade and Below (FBCB2), a tank-infantry phone, a .50 caliber thermal sight, a power distribution box, a rear slave receptacle, an eye-safe laser rangefinder and driver’s vision enhancement. This situational awareness package increases the M1A1 Abrams tank’s fighting capability by providing soldiers with an electronic graphic of the battlefield with icons for friendly and enemy forces, and provides a tank commander’s thermal sight for the .50 caliber machine gun.
The tanks are scheduled for delivery to the Army beginning in July 2008 and continuing through October 2010.
