Akagi, U.S.S.

Star Trek: The Next Generation
Episode: TNG 201 - Redemption, Part II

One of the 23 ships that comprised Picard's blockade to try and choke off Romulan support, for the Duras faction, during the Klingon civil war.

In a ruse with the U.S.S. Hornet, the Akagi allowed a hole in the tachyon sensor net and then dropped back in wait.
