The UCA Navy is the most powerful navy in the known universe.
The UCA Navy's technology far surpasses that of the Helghast and the ISA navies combined. This is demonstrated with the complete and utter destruction of the Helghast navy in orbit in an extremely short time.
The next time the UCA navy is seen is during the Helghast invasion of Vekta where one of their ships is seen destroyed by the SD platforms weapons. The ships in the UCA navy are considered to be dreadnoughts compared to the ships in the ISA or Helghast navy.
