GD’s M1 Abrams System Support Contracts
The USA’s M1 Abrams tank fleet was fielded in the 1980s, and has undergone a number of modifications and improvements over the subsequent decades. It’s a high-performance, high-maintenance tank – and any vehicle that’s used accumulates wear. Meanwhile, the tides of innovation and technology roll on, and electronic parts in particular may not be available for order 15 years after the tanks were produced. When these realities are coupled with lessons learned about the wear patterns and performance of various components over the years, it becomes possible to gradually architect improvements to the fleet by substituting new components and/or assemblies.
Enter the Abrams systems support contracts. They fund engineering studies on Abrams tanks to identify improvements for the fleet, and replace obsolete parts in order to maintain the USA’s tanks at high operational readiness rates. The contracts have come in a small but steady stream – this article covers all FY 2007 contracts, and future contracts going forward, in order to throw a bit of a spotlight on this effort.
