McKenna

Admiral McKenna was a Starfleet officer during the 2260s.

In 2268, McKenna assigned the USS Enterprise (NCC-1701) to transport Ambassador Zarv and his specialists to the Ammdon system. When Captain Kirk protested, noting that the ship and crew required some much-needed maintenance work and shore leave, McKenna replied that the Enterprise was the only nearby ship in good enough condition, and that there was no time to waste.
