Withdrawal of the TOAs recalls that Spain has launched a plan to reduce its veteran fleet of M113 TOA that contemplates the withdrawal of more than half of the vehicles in service, going from 1,250 platforms currently operational to about 600. “Currently there are 1,250 platforms in service of which, after a planned reduction, will remain in the first phase around 770, which in successive phases will continue to be reduced,” the Spanish Army said.

Spain has also been working for some years on the modernization of part of its TOA. This program affects just over 700 platforms in the fleet. The update began in 2015 and is expected to end in 2023. “The modernization is being carried out by the logistics elements of the Army, with no intervention from external elements other than providing the necessary spare parts,” details the Army. The works fundamentally affect the suspension of the vehicle and do not include improvements in the powertrain or in the fire capacity of the fleet.

New chain support vehicle

In parallel, studies have already begun for the development of a new Chain Support Vehicle [CSV] that will replace the entire TOA family. According to current Army plans, the replacement of the M113 with the future CSV will begin no earlier than 2027 and is scheduled to end in 2035. By that year, all platforms of the TOA family are scheduled to be decommissioned from service.
