M8 Ridgeway Armored Gun System
M8 Ridgeway Armored Gun System, Aberdeen Proving Ground.
In the 1980s, the United States Army began looking for a replacement for their M551 Sheridan tanks. Several attempts over the years to update or replace them had proved unsuccessful. The Armored Gun System (AGS) competition was initiated and in 1992 FMC/United Defense's vehicle was selected.
A total of six prototypes were eventually built for the US Army under the designation of the XM8 AGS. The M8 was later type-classified by the US Army in late 1995 and initially slated for production in 1996.
United Defense has reportedly been seeking overseas customers, so far without success. Taiwan at one point expressed interest as a replacement for its fleet of M24 Chaffee/M41 Walker Bulldog light tanks but would not commit following cancellation by the US.
