I recheck the scene and check with dubs in spanish and english and Alto calls it the Macross Q4 Global when he finally was close enough to read the designation, no SDF anything on it, the only other number on the hull is 117 that is the research fleet it was assigned to.
I agree with Duke, the SDF designation was given to the Megaroad ships being the Macross the only Macross class ship with SDF.
