Modernization plans for the SIDAM 25 were drawn up in late 1994, when Italian engineers proposed the up-arming of the vehicle with Mistral surface-to-air missiles in order to give it better long-range capabilities and improve its performance as a whole.

The missiles were to be distributed between two launchers, with each launcher containing three missiles. As such, the vehicle could then utilize the missiles against targets at long range, whilst preserving the cannon armament for close-range engagements.

The modernization of the SIDAM 25s with Mistral SAMs was expected to begin in the early 2000s, alongside some other potential upgrades as well.
