USS 
A Prometheus-class starship
The USS Typhon, NCC-74930, is our Prometheus-class Starfleet ship. On screen, the experimental USS Prometheus was designed for deep-space tactical assignments. Its sleek profile and four prominent warp nacelles make it recognisable, but those are not the whole set. Two smaller nacelles are housed in the saucer section and deploy when the ship separates, giving the class six nacelles across its three sections.
Many Prometheus-class chapters in STARFLEET use registry numbers in the 749xx range, although there are exceptions. We chose NCC-74930 to suggest that the Typhon is a later build than ships with lower numbers. In our ship's story, that leaves room for newer systems and refinements. Registry numbers are a useful cue for that story, rather than proof that every vessel was built in numerical order. We do not need to invent specific upgrades before deciding what belongs aboard the Typhon.
Three ships working as one
Multi-Vector Assault Mode
In multi-vector assault mode (MVAM), a Prometheus-class ship divides into three warp-capable sections. Each can manoeuvre and engage a target independently, allowing the ship to approach from different directions before its sections rejoin. The saucer section deploys its smaller pair of nacelles, while the upper and lower engineering sections retain two larger nacelles each. Star Trek: Voyager first shows the USS Prometheus doing this in “Message in a Bottle”.
For the Typhon, the three sections are also a fitting image of our crew. Departments and people bring different skills, and they can work separately when a task calls for it, but they remain part of the same ship. The three-headed figure in our emblem carries that idea into the chapter's own design.
The image above depicts the class prototype, USS Prometheus (NX-59650), rather than our chapter's USS Typhon. The Typhon's own MVAM artwork appears below.
Multi-Vector Assault Mode
More than multi-vector assault mode
The on-screen Prometheus was fast, heavily defended and highly automated. It had regenerative shields, ablative hull armour, phasers and photon torpedoes. Its ship-wide holoemitters let its Mark II Emergency Medical Hologram appear beyond sickbay. In “Message in a Bottle,” Voyager's Doctor tells the Mark II that he can even leave his ship, thanks to a mobile emitter from the 29th century. He doesn't demonstrate that ability in the episode.
These details describe the Prometheus-class prototype shown in Star Trek. They give us a starting point for imagining the Typhon, without turning every detail of that vessel into a claim about our chapter's ship.

Greek names and inspiration
Prometheus and Typhon are names drawn from different Greek myths, but our choice of Typhon was inspired by the starship rather than a connection between their stories. Prometheus is remembered for bringing fire to humanity. Typhon is a fearsome, many-headed figure who challenged Zeus. In “Message in a Bottle”, the USS Prometheus shows what a beast it can be in battle. With its Starfleet crew dead, Voyager's Doctor and the ship's Mark II Emergency Medical Hologram incapacitate the Romulan hijackers with neurozine and take control. The two holograms then use the ship's multi-vector assault mode against the pursuing Romulan vessels.
That is the spirit behind our name. Typhon was a frightening beast in Greek mythology. Our USS Typhon takes its name from that formidable figure, imagined as a defender of the United Federation of Planets and a ship that enemies seeking to harm the Federation would have reason to fear.
Our dedication plaque carries another Greek connection. A saying commonly attributed to Alexander the Great reads, “There is nothing impossible to him who will try.” For the Typhon, we adapted it to “There is nothing impossible to those who will try.” The change uses gender-neutral language that speaks to everyone in our crew today, while keeping the spirit of the familiar saying.
Where to see the class
- Star Trek: Voyager, “Message in a Bottle” (Season 4, Episode 14): the best look at the USS Prometheus, its interior and multi-vector assault mode.
- Star Trek: Voyager, “Endgame” (Season 7, Episodes 25–26): a Prometheus-class ship appears with the Starfleet task force near Earth. The episode does not establish whether it is the original USS Prometheus.
- Star Trek: Enterprise, “Azati Prime” (Season 3, Episode 18): ships of the class appear in an alternate 26th-century timeline.
- Star Trek: Prodigy, “Preludes” (Season 1, Episode 16): a Prometheus-class ship is shown making first contact with the Vau N'Akat on their homeworld, Solum.
These are appearances of the class, not of our chapter's USS Typhon.
You can also encounter the Prometheus class in Star Trek Online. Players can fly a Prometheus-class Advanced Escort, while the multi-vector version lets them command one section as the other two fight alongside it. The game offers another way to experience the design, but its appearances on television are what establish the class on screen.
Our ship's expanded story
Our USS Typhon, NCC-74930, has its own Star Trek Expanded Universe wiki page. It is a place to explore the fun, invented history of our chapter's ship. That fan-created story adds to our identity without claiming to be an on-screen appearance.
For the Prometheus class itself, start with Memory Alpha's Prometheus-class article for the on-screen design. Then explore the Star Trek Expanded Universe Prometheus-class article and Memory Beta's Prometheus-class article for material beyond the television episodes. Details can differ between sources.
