The USS Guanine (NX-88708) was a Cosmos-class Starfleet prototype starship that was constructed in 2380. (Star Trek: Pioneer)


Guanine comes from biochemistry. It is a compound that occurs in guano and fish scales, and is one of the four constituent bases of nucleic acids. A purine derivative, it is paired with cytosine in double-stranded DNA.

Test flightsEdit

In 2380, Admiral John Hayes was aboard the USS Guanine when there was a malfunction during the ship's Quantum slipstream drive testing trials. Commander Taylor Ferguson, the ship's executive officer, Admiral Hayes, and the entire engineering crew died in the explosion. ("The Teacher")

After the accident, Starfleet Command halted the test flights. Test flights were schedule to resume in late 2382. ("For Better or Worse")
