In 1936 CT Mato Grosso undergone one large repair and structural remodelling at Brazilian Navy Arsenal Rio de Janeiro.
Initially, the ships of the Southern Naval Force were employed in escort tasks to coal ships heading to the port of Criciuma, in the state of Santa Catarina. These coal shipments were vital to supply the most populous states of Brazil which were São Paulo and Rio de Janeiro and this lasted until 1944 when they were replaced by 6 newly launched corvettes, being relocated to the tasks of protecting the port of Rio de Janeiro until the end of the conflict..
