Simulation(‘SIM’) is a type of Internet role-playing through live-chat, email, or more recently NOVA.

The Fifth Fleet is a free online group dedicated to this form of fun roleplay & collaborative storytelling. See our SIM Guide and consider joining a “SIM”!

All the simulations within The Fifth Fleet take place, in the same interconnected universe, across multiple storylines. These storylines reflect the ‘prime’ canon timeline shown in STAR TREK Enterprise, The Original Series, Discovery, The Next Generation, Deep Space Nine, Voyager, Picard and the TMP and TNG Movie Eras. The Fifth Fleet currently runs 3 storylines, with each SIM operating within one. To learn more about each storyline, please click the banner below.


The Confederacy between the Klingons, Romulans and Federation has collapsed. The Fifth Fleet stands at the point where all 3 galactic powers meet.

In 2394, the first Bajoran to be elected to the post of Federation President, Relan Meru, has been assassinated.

A year later the Federation continues to mourn the loss of its second President in a decade, coupled with recovery from the Dominion War & synth attacks on Mars, tensions across the galaxy and within the Federation itself have never been so high.

Join the USS Firebird, USS Solaria and Deep Space Eden, as they deal with the galactic ramifications!

We lost the war.

After six blood-soaked years, the surviving shreds of the United Federation of Planets surrendered to the Dominion.
