U.S.S. Theurgy | Theurgy-class Federation Starship


I would like to unveil my Theurgy-class for TrekCore, and with it, the first rendered images were this ship was featured. 

While she was inspired by the Odyssey and Bellerophone-classes in Star Trek Online when I made the design (retaining the MVAM capacity of the Prometheus-class) the 3D model was a commissioning by Omar Tavera (Omardex) on DeviantArt ( & The idea and design might be mine, but this project could not have turned out the way it did without Omardex. The model was made in Cinema 4D and rendered in Thea Render, which is quite ironic given that the A.I. of the ship is named Thea.

Please note that some liberties have been taken with the commissioned year of the Odyssey-class, being earlier than in Star Trek: Online. Also, in Star Trek: Theurgy, we have pushed the implementation of the slipstream drive ahead a couple of years, not being on the starships just yet.

The Theurgy-class is meant to be the pinnacle of Federation starship design and will carry the Federation into a new generation of exploration in the next century. It is one of the largest starships ever created by Starfleet, surpassing even the Odyssey-class in size. The USS Theurgy is the only one built, and exists as an advanced prototype of its class until it is taken into production. Officially, both the Odyssey and the Theurgy-classes were rushed into production because of the Romulan Civil War. Unbeknownst to the public of the Federation and Starfleet as a whole, it was the corrupted Starfleet Command that pushed the production ahead of schedule for sake of their own clandestine agenda.

The Theurgy is a Multivector Dreadnought, designed for long-range exploration, diplomacy, and deterrence. It's expanded science laboratories allows it to take on extended missions that will take it far from a starbase or other Starfleet facilities. The Theurgy-class has ample room for cargo or passengers, and will easily be tapped for rescue missions or civilian evacuations in war zones when it is taken to mass-production. A Theurgy-class vessel also has regenerative shielding, ablative armour and Multivector Assault Mode (MVAM) - in which the ship is able to attack enemies from three different directions simultaneously (Note: This feature was seen in detail in the Star Trek Voyager series - Episode 14, "Message in a Bottle", Season 4 - where a Prometheus-class starship was able to use this feature).

The ship spends the vast majority of its life in Standard Operating Mode (SOM). Multivector Assault Mode - where the ship is divided into three parts - is typically reserved for battle situations. All hulls, or Vectors, are Warp capable, and thus MVAM can be engaged during warp. This was an original design that had been scraped, since due to the separation of the vessel, each section was only one-third the power of the whole ship. Adding a Battle Bridge and computer cores on each section of the vessel allowed the section to perform more adequately, plus the addition of multiple Sickbays to treat the wounded.

The warp core arrangement is unique. The efficiency of a warp core is in part dependant on its height - the longer a core is, the more accurately the matter and antimatter streams can be controlled. To overcome this, the warp core has no less than three reaction chambers along its height. During normal operation matter is fed in at the top of the core and antimatter at the bottom, as in any normal warp core. The fuel streams past directly through the upper and lower reaction chambers and continue down to their meeting point in the central chamber. The core thus operates in a manner similar to any standard model, achieving high efficiency through the long core design. The central reaction chamber lies above the separation plane between Vector 02 and 03, and once the ship splits, it is shut down. In the lower engineering section a secondary matter feed just under the central chamber comes into operation, feeding deuterium down to the lower reaction core.

MVAM - Multivector Assault Mode



If the ship encounters a battle situation, the Commanding Officer may choose to activate Multivector Assault Mode (MVAM). In MVAM, the ship splits into three independent sections, all of which have warp capability and a powerful weapons load-out. Additionally, the ship's Main Bridge is on Deck 01 in the Saucer section (Vector 01). Vector 02 and 03 have Battle Bridges that can be fully crewed during MVAM if the Commanding Officer does not chose computer control from Vector 01. One additional item of interest: nearly a third of the ship's weaponry is hidden during SOM and only becomes available during MVAM.

Torpedo Pod Launcher Array & Palletized System Modules


Torpedo Pods


Since the Dominion War, Starfleet has been seeking options for engagement in the traditional torpedo gunnery blind spots along a ship's sides, as well as ways to provide a heavy enough long-range punch at a rate that could effectively saturate a target's defences, which would need to be a faster rate of launch than could be accomplished with individual torpedo tubes.  As such, torpedo pods and their associated launchers were developed.

As a result of this requirement, Starfleet Tactical R&D developed reusable pods carrying a number of torpedoes and an on-board power supply, launching mechanism, computer and control system, which are fed their targeting information from the launching ship or as the capability becomes available, from Pod Control Modules (part of Starfleet's Palletized Systems Module, or PSM, program).  However, despite the wish of some within Starfleet Tactical R&D, it was determined that using all-up main-tube torpedoes, or even the Mk XXVII Intermediate Torpedo, in the pods would be impractical.  Indeed, the mass and volume of the larger warheads would prove unmanageable within the pods themselves as it would be impossible to mount linear accelerators large enough to reach meaningful launch velocities; another deciding factor has to do with the limited magazine space within starships as there simply is not enough available internal volume to carry sufficient numbers of loose torpedoes to refill the pods with.  As such, the pods are designed to house and launch 15 of the same Type V micro-torpedoes as carried internally in the Valkyrie-class fighter and the sheer volume of fire in each pod was deemed an acceptable tradeoff for the much smaller individual warheads.  

But what makes pods most attractive is that they do not necessarily have to be activated and fired as soon as they are launched.  A ship could lay a pattern of pods and fire several of them at once (up to its maximum control capacity) into a massive salvo.  And given pods' extremely stealthy nature in their low-powered standby mode and their lack of immediately apparent signature when being deployed, a vessel could even lay several patterns and either launch a number of massive salvos or maintain a steady stream of fire for an extended duration in "ripple fire", reallocating fire control and telemetry links to a fresh pod after one has been fired. 

However, only a pod-laying ship has the on-board facilities to quickly reload and recondition a pod for launch after recovery.  On others, once a pod has been recovered each tube must be individually reloaded and its covers replaced before the computer can be flashed and its battery replaced.

However, pods are unarmoured and unshielded and as such are extremely vulnerable to enemy fire and collateral damage, and when actively engaged, an officer commanding a pod-equipped ship has to decide whether he would rather risk laying a larger pattern with a heavier salvo at the risk of his pods being damaged or destroyed before he can fire them, or launching individual pods and flushing them immediately, sacrificing weight of fire for any given salvo for the knowledge that he will not lose any full pod to enemy fire or proximity damage.

At this point in time, only a handful of ships in Starfleet are considered to be true pod-layers, with the Theurgy being the only one to have been intended from the keel-up with that particular capability.  A few have been refitted to that status, and all of them have been attached to Admiral Sankolov for the time being.  

However, any starship can make use of them, keeping them internally in their shuttle bays or any external cargo hold with a large enough door to fit them.  Or even having them attached to their outer hull using magnetic grapples, although such would change its hull profile, which in turn would affect the efficiency of its warp field and lower its maximum speed.  Another disadvantage has to do with a pod's inherent fragility and should a hit come through and strike the pod, there is a chance the weapons my explode, with catastrophic implication for the ship to which the pod is in contact with.  Also, ships that have not been designed or refitted as pod-layers lack the telemetry capability to lay and control more than small patterns, the size of which is dependent on the ship's individual capabilities.  

That problem will eventually be alleviated with the issue of of Pod Control Modules, which were designed to give ships that are not designed or refitted to serve as purpose-intended pod launching platforms, yet expected to carry or control pods for a specific mission, the capability to control salvos of meaningful weight.  Each PCM can control up to 18 pods at a time.  However, such modules were unavailable when the intended test bed platform, the USS Theurgy, was commissioned and the alternate test bed, the Archeron, was deployed before they could be sent.  However, there are 4 such pallets forward-deployed to a classified location near the Romulan Neutral Zone.

Sequence of engagement with pods:

1- Mother ship drops her pods (individual launch or laying patterns) OR
2- Targets are acquired and telemetry links are established to pods
3- Torpedoes are launched from pods
4- If applicable, control links are shifted to unused pods
5- Repeat as required
6- Spent and/or unused pods are recovered for reconditioning and re-loading

Alternative, a dedicated pod-launching vessel may fire the pods directly from its launchers and the empty pod will be flushed into space for later recovery.  The trade-off to the higher rate of fire so achieved is a lesser salvo weight. Another alternative, depending on the tactical situation, is for the crew that man the broadside launcher arrays to keep the pods in place, close the array, and restock the pods inside the ship, but would entail 2 minutes of reloading for each pod.

Palletized System Modules (PSM)

Even after the number of recent conflicts, Starfleet's use of combat-centric vessels such as the Defiant and Prometheus classes remains a controversial issue.  And even after the Prometheus-class project proved to be a viable option, purpose-designed warships remain unpopular and Starfleet has been looking for ways to keep ships intended for battle in service without diluting their tactical potential by stripping away capabilities.  And, at the same time, Starfleet Tactical was seeking out ways to improve any vessel's combat potential without the need to build new hulls.

And when both requirements collided, the Palletized System Modules (PSM) program was born.  The concept is rather simple, and quite similar to the plug-and-play capability enabled by USB ports in the early 21st century.  A ship with PSM capability would have, under removable hull panels, universal connectors that would provide power and control linkages to to an standard-sized module which would provide additional capability to its host vessel.  The installation process for any module is rather simple: the external hull panel is removed and then stowed into a cargo bay or other facility, and either with the use of an auxiliary craft or an EVA the module is brought to its location and it is secured in place using maglocks and physical clamps.  

As it stands, only the Theurgy-class prototype has been designed from the keel up for this capability, but several ships including the USS Archeron and a handful of vessels in her task force have been refitted for it.  While building a new class that is intended to receive this capability is fairly easy, the refit process requires Starfleet engineers to readjust a ship's power budget, often involving changing its power plants altogether, in order to ensure every system can run properly.  This is one reason that when she was first designed, critics referred to the Theurgy-class as being over-powered and over-engineered, despite the fact that her hull can accommodate up to X additional pallets between her three vectors.

However, the PSM is intended to be a staple of future ship design, and theories surrounding the building of entirely modular starships are being explored at this time. 

Types of pallets available at this time:

Sensor (broad-spectrum or specialized)
Communications, Command and Control (for ships that are not inherently flagships but could serve in that role)
Pod Control Modules (Only four have been produced so far and have been forward-deployed to a classified location near the RMZ)
Palletized Point Defence Modules
External Machinery Points
External Gantry Systems (ie: for repair ships) 
Additional Shield Emitters
Additional Tractor Beams

I absolutely LOVE these images!  The detail you put into this looks fantastic!  I like they way you laid out the Valkyrie's munitions payload.  The icing on the cake would be some in-flight images with other ships, or a space station or planets, in the background.
