Venus Warp Core Assembly Plant

The Venus Warp Core Assembly Plant is the largest single manufacturer of warp cores in Federation space, and is suspected to be the largest single assembly point in all known space. It operates in orbit around the planet Venus, or Sol II, in the Sol System, Sol Sector. It is one of the most highly secured facilities in the Starfleet network, with no non-official travel allowed on any matching Orbital Track, while the facility itself is easily the equivalent of an Outpost in terms of defenses. Staffed by a team of four thousand dedicated staff, plus a thousand Starfleet operations, security, and engineering personnel, the plant operates year round with two shifts. With the modern surge of required builds, it has had to move to two shifts and expand facilities.

ONA-IV-L Standard
The warp core for the Centaur-B frigate, the Venus plant's is currently producing six per year, well down on its high point of 15 cores per year, as the Centaur-B refit cycles reaches an end. Nearly 30 Centaur-As across the Federation were refit to -B specs in the space of four years, with another dozen new builds, and most of the necessary warp cores were assembled at Venus.

Type-E Block-4 Heavy
Previously this line was responsible for the Block-3 warp core used by the Centaur-A, but is now producing the Block-4 used by the Excelsior-A, a very similar technical base, though weighing in at twice the size. This production line too has slowed as the -A refits complete, but is still producing four core per year to provide a stock of spare parts for repairs and replacements as needed. The Excelsior-A project required 22 refits, and nine new builds. As this 200kt warp core is a difficult build, most orders even for member fleets came through Venus rather than investing in bespoke constructions.

ONA-III-H Experimental & ONA-III-H Production
The Ambassador project employs the ONA-III-H warp core, which was a bleeding edge experimental design when the explorer was first conceived of. This warp core is of similar weight and size to the Type-E Block-4, but considerably more oomph. The first two builds were bespoke from the VWCAP workshop, and that learning experience was put into practice for the production line that delivered two warp cores per year for the first batch from Utopia Planitia Fleet Yard and has now ramped up to 4 per year. Thus far, only the Sarquel Treaty Organisation is building their own ONA-III-H cores.

Mk IX Sublimator-Compressor
A line dedicated to producing a steady supply of the Mk IX Sublimator-Compressor injection system used by the Ambassador project. This component weighs nearly half that of main core assembly, a reliable, heavy-duty injector system.

Workshop
For bespoke construction, run by the legendary Warp Core engineer and architect Olivia Campbell. Many of the experimental designs used in Starfleet are built in this workshop, as are urgent replacement warp cores for out of production ships.

Research & Development
The Venus Warp Core Assembly Plant includes a design bureau that creates warp core components. These are referred to internally as the A-series (for Aphrodite, a mythological human figure with links to the plant in primitive astronomy), but are known as the Type-II series by ONA.
