History
In June 2009, the F Constituição (F42) participated in the recovery mission for the wreckage of Air France Flight 447.

On the 20th of February, 2010, the Constituição brought 12 students, faculty, and crew of the SV Concordia ashore after they were initially rescued by merchant vessels. The Concordia, a tall ship floating classroom operated by the West Island College International's Class Afloat program, was abandoned approximately 300 nmi south east of Rio de Janeiro with all 64 people aboard making it to life rafts. The remaining 52 students, faculty, and crew were to be transferred from merchant vessels to the Constituição and another Brazilian frigate, but weather and other concerns prevented that.
