Events

• This decade is the first of two that represents the height of perimeter ship combat on Klingon borders.

• Research into possible use of dilithium instead of lithium to control warp core reactions is begun.

• All of the variants of the Horizon class receive new auxiliary craft assignments.

• The significance of the Willall challenge upon Klingon politicians and scientists is uncovered.

• USS Truman (NCC-1115, Proxima class) serves as the command ship in anti-Klingon actions.

• The following battles occur (presumably during the Four Years War): Nozseca (with five Icarus/Ashanti class battle cruisers severely damaged); Donatu (three Icarus/Ashanti class destroyed); Second Arquin (two Ashantis are ambushed with lethal results); Final Axanar.

• USS Byrd (first of her class) initiates first contact with the Lyran Star Empire during her 25-year voyage of galactic exploration.

The decade is presumed, based upon the assumption the contact occurred on the outward portion of the mission. (It could also occur on the return leg, if the mission plan did not replicate the first leg on the second one.)

• Marklin class light destroyers see brief service on the Klingon front.
