The F-302, X-303 Prometheus and BC-304 are related parts of Earth’s Stargate fleet, but they are not three versions of the same ship. The F-302 is a small fighter-interceptor, the X-303 Prometheus is Earth’s first major capital ship, and the later BC-304 family is a larger carrier/battlecruiser design associated with ships such as the Daedalus.
This naming distinction matters when searching for a model. It also prevents the X-303 Prometheus from being confused with the unrelated Prometheus-class starship in Star Trek.
F-302 vs X-303 vs BC-304 at a glance
- F-302: fighter-interceptor; compact, winged display silhouette.
- X-303 / Prometheus: an individual early Earth capital ship and the only vessel of its class.
- BC-304: the later deep-space carrier/battlecruiser family, commonly associated with the Daedalus-class design.
- Best compact model: F-302 Fighter Interceptor.
- Best large Earth-fleet centrepiece: 18-inch X-303 Prometheus MKII or 25-inch BC-304 MK2.
F-302 Fighter Interceptor
The F-302 Fighter Interceptor is the smallest and most aircraft-like of the three. Its swept wings and compact body make it suitable for a desk, a shallow shelf or a grouped hangar-style display. It is a good first Stargate ship for collectors who want an immediately recognisable Tau’ri craft without committing to a long capital ship.
The F-302 is the production fighter that followed the experimental X-302. It is carried by larger Earth ships, including the Prometheus and BC-304 family. This is why the fighter often appears in the same fleet discussions even though it occupies a completely different size and role.
X-303 Prometheus
The 18-inch X-303 Prometheus MKII represents Earth’s first major home-built capital ship in Stargate. Its broad, layered hull is visually heavier than the F-302 and makes a stronger single display piece. At 18 inches, it can still share a shelf with another ship if enough width and stand clearance are available.
Search terminology around this model can be confusing. Prometheus is commonly described as the X-303 and later BC-303; it is not the Star Trek Prometheus-class vessel. If you are comparing the two franchises, see our separate X-303 versus Prometheus-class guide.
BC-304 MK2
The 25-inch BC-304 MK2 is the largest Earth-fleet model in this comparison. It suits a dedicated shelf or cabinet and should be measured as a complete display, including the stand. The length gives its carrier-like hull enough space to read clearly from across a room.
The BC-304 is the later class that follows the technological path established by Prometheus. It is a family designation rather than the name of one specific ship, which is why collectors may also search for Daedalus-class, Odyssey or Apollo when researching the design.
How to display the three together
A strict fictional scale would make the F-302 extremely small beside either capital ship, so a home collection normally works better as a representative fleet. Place the BC-304 or Prometheus at the rear, lift the F-302 on a smaller forward stand and use spacing to communicate hierarchy.
If you only have room for two, pair the F-302 with the X-303. Their different shapes explain the fighter-and-carrier relationship immediately, and the 18-inch Prometheus is easier to place than the 25-inch BC-304.
Other Stargate spacecraft in the collection
Earth ships are only one part of the range. The Puddle Jumper offers a compact Ancient utility craft, while the 12-inch and 15-inch Asuran Light Corvettes provide two display sizes. The collection also includes the O’Neill-Class Battlecruiser, Ori Fighter, Ori Mothership, X-301 Interceptor and 16-inch Destiny and Seed Ship.
Which Stargate model should you buy first?
Choose the F-302 for the smallest footprint and strongest aircraft-like silhouette. Choose the X-303 Prometheus if SG-1’s early Earth space programme is the focus of your collection. Choose the BC-304 when you want the largest Tau’ri fleet centrepiece. For an Atlantis-focused shelf, start with the Puddle Jumper instead.

Frequently asked questions
Is the F-302 the same as the X-303?
No. The F-302 is a fighter-interceptor. The X-303 is the much larger Prometheus capital ship.
Is the X-303 a BC-304?
No. Prometheus is associated with the X-303/BC-303 designation. The BC-304 is the later carrier/battlecruiser class.
Is the Stargate Prometheus a Star Trek ship?
No. The two franchises use the name independently. The Stargate X-303 Prometheus has a broad military hull; the Star Trek Prometheus-class is a Federation starship with a different design and lineage.
Are these models supplied assembled?
Yes. The linked Printverse3D listings describe physical 3D printed models supplied fully coloured and assembled. Check each product page for dimensions and included display components.
