Irapina starship

An Irapina starship is an unnamed starship type of planetoid size that was under the control of the psychokinetic Irapina. Each vessel is a transport and generational ship containing 2.5 billion Irapina.

History and specifics
In the 23rd century, an expeditionary invasion force of four Irapina starships was headed for the Sagittarius Arm of the galaxy and Federation space. Each vessel was nearly the size of the rogue planetoid Anomaly. By 2269, the fleet was 25,000 light years distant with an expected arrival in the 33rd century.

In 2269, leaders of the fleet elected to use psychokinesis to transport a small advanced scout force to test Federation resolve, a task which expended enough energy to delay the fleet's arrival by a century. The scouts were transported to the planets Anomaly and Organia, where they engaged in telepathic illusory contests. On Anomaly, an immature member of their organ-donating caste died, and two adults were rendered unconscious, during the tests against Captain James T. Kirk and Commander Spock. Results prompted the invasion fleet to divert towards the Orion Arm of the galaxy with an ETA in the 34th century.

Kirk noted in his captain's log that Starbase 4 might be able to locate the Irapina fleet due to its large mass.
