A UCA Cruiser engaged in combat.

The UCA Navy is the naval arm of the United Colonial Nations.


The UCA Navy's technology far surpasses that of the Helghast and the ISA navies combined in which UCA ships are considered to be dreadnoughts compared to ISA and Helghast ships. This is demonstrated with the complete and utter destruction of the Helghan Administration's naval fleet in orbit in a matter of hours without losing a single vessel during the First Extrasolar War.

During the outbreak of the Second Extrasolar War, the UCA Navy provided assistance to the ISA troops during the invasion of Vekta by Helghast forces, but arrived after the initial invasion. The reinforcement suffered the loss of two cruisers to the Helghast-controlled SD Platform.
