Service history[]
The Alliance designed the Rex as a hybrid between the 24th century Federation Starfleet Defiant-class escort and the contemporary Dominion Jem'Hadar fighter. Like the latter, the AFS Rex was often deployed with two wing-mate starships in a squadron.
This ship was named after Dukan'Rex, both representing connection between the Gamma and Alpha Quadrants. (STO website: Both Worlds: The King and Collective Event!)
The Rex, which bore the CSN registry number 04, representing the Alliance's fourth joint capital ship type after the AFS Khitomer, AFS Temer and AFS Jarok. (STO - Incursion missions: "Welcome to Earth Spacedock", "Explore the Flotilla", "First City")
