Galaxy Class Explorer/Heavy Cruiser
Up until 2372 when the USS Enterprise E was comissioned, the Galaxy class Explorer was the most powerful and advanced starship in the Federation. As with all UFP designs, the UFAS expanded upon it, making room for many improvements. The entire deflector grid was re-designed & replaced with a far more powerful one and the sensor arrays from the Ralston class have been installed giving the Galaxy class the best sensor capability for a ship of it's size. Two new power generators were added to the Main Deflector increasing it's range and power. Many of the ships have also been outfitted with a limited number of Type XII Phaser Emitters. The upgraded Galaxy class forms the backbone of the UFAS's Fleet as a capable Explorer/Heavy Cruiser.
