1.0 LOTUS-CLASS INTRODUCTION
1.1 MISSION OBJECTIVES
Pursuant to Starfleet Exploration Directives 902.3 & 914.5, Starfleet Defense Directives 138.6, 141.1 & 154.7, and Federation Security Council General Policy, the following objectives have been established for a Lotus Class Starship:
- Provide a mobile platform for a wide range of ongoing scientific and cultural research projects beyond current interstellar vehicle capability.
- Extend current Starship design and deployement as the primary instrument of Starfleet's exploration programs.
- Provide autonomous capability for full execution of Federation policy options in distant, uncharted areas for extended period of isolation, equal to a small space station or outpost.
- Incorporate recent advancements in warp and transwarp technology and improved science instrumentation and tactical capabilities.
Length: 1285.02 meters
Width: 927.46 meters
Height: 199.91 meters
Weight: 9,000,000 metric tonnes
Cargo capacity: dependent upon mission type
Hull: Ablative armor overlaying a duranium microfoam/tritanium composite hull, augmented by synthetic castrodium alloy structural members. The whole underside of the secondary hull is a storage area for regenerative armor replicating material, providing a passive armor four meters thick in this whole area, thus protecting auxillairy crafts, main engineering sections and most of the ship thoroughly in orbital mode and, when properly oriented, against hazardous planetary and stellar body-phenomenon or hostile situations, as per starbase established designs. This can also be used a s a thermal shield for a relatively safe planetary crashlanding in case of loss of orbit.
Number of Decks: 43 (42 habitable) 4.6 meters/deck including bulkheads and 1.0 meter jefferies tubes
1.3 GENERAL OVERVIEW
The Lotus Class starship entered service in 2410, marking the crowning achievement of over a century of engineering advancements, starting with the Transwarp Development Project in the late 23rd century and the Galaxy class design of mid-24th century. With currently only one in service, the Lotus Class is servicing the Federation and Starfleet.
Lotus Class vessels are to be the largest in the fleet along with the capital class of the Odyssey design, on par with the massive Romulan D'Deridex, built to boast Starfleet's most advanced technology and show the Federation's presence as if a core member world was next door with it's own mobile space station or outpost.Initial production of the Lotus Class began at the Advanced Starship Design Bureau Integration Facility, Utopia Planitia, Mars, and will later expand to include other classified bases.
The first was prematurely assembled and launched from the Advanced Starship Design Bureau Integration Facility, Utopia Planitia, Mars, in early 2410 to help resolve the situation of the Azimuth Horizon Incident, before being consolidated with the rest of the primary production facilities in the Hromi Cluster, namely Starbase Lotus, as the ship was delivered to the elite Starfleet division of Lotus Fleet, already commended for it's significant role in stopping the final Borg Invasion of 2409 and now following their success during the operation.The design of primary and secondary hulls has been a staple of Starfleet since it's inception over two hundred years ago with the legendary Constitution Class.
Advances in that design includes the emergency separation mode, where the primary and secondary hull split into two separate vehicles, each capable of individual flight maneuvers. However, this design was initially an emergency response only, which required the ship to be towed to a Starbase to be put back together, until the advent of full separation mode with the Galaxy class. Now the Lotus Class, like the Galaxy class, Sovereign class and all twin-hulled designs that followed, can perform a saucer separation and rejoin itself, one of the biggest advances since the procedure was conceived. This advance in saucer separation makes it possible for the Lotus Class to use the maneuver routinely as a tactical maneuver, instead of a strategic contingency. The advancements and problems of the ultimate version of this concept, the Prometheus class, were resolved with Odyssey class carrying a small escort-type vessel in addition to it's saucer seper mode, an improvement that was also included in the Lotus class. Moreover, the size of the Lotus class allowed to provide the separated saucer with it's own hull-integrated warp nacelles, just like what had been tested successfully on the Defiant class, allowing it to reach up to warp 7 as an independent starship even if deprived of a secondary hull. Beyond the obvious tactical advantages, already tested with the Prometheus class, this would allow the crew to return home even in the advent of loosing the stardrive in a far away area; a lesson taught by the incredible hardships of the USS Voyager when it had been lost in the Delta Quadrant.
The secondary warp core needed for this, again build from Defiant class tested designs, is also what allows the successful implementation of transwarp technology when the vessel is whole.
The Lotus Class is well armed. Describing it as the best-armed ship in Starfleet could lead to arguments, but the vessel is able to hold it's own, even in some mismatched battles. Being the first vessel to mount the Type-XII Starbase-issued Phaser Array has made the class a foe to contend with. However, at the time of it's design, Starfleet decided that it would be best to limit the amount of torpedo tubes aboard the vessels. Designers went with five in the original specs. After layout problems and Starfleet's recommendation for less, the designers went back to the drawing boards. They decided to use a swiveling, larger launching system, one that would be able to process a loadout of ten casings. There were two of these launchers placed into the plans, one forward and one aft (plus two extra launchers for the separated saucer, one forward and one aft available only when in seper mode); Starfleet approved. Designs of other classes have had increasingly more amounts of torpedo launchers and tubes placed on them, to counter the new and increasingly more powerful threats facing Starfleet, but these were deemed sufficient to provide the Lotus class starship to provide adequate response in synergy with its other tactical systems.
1.4 CONSTRUCTION HISTORY
Long before 2409, when the Lotus Class officially began, the seeds were being planted. During the waning days of the failed Transwarp Development Project in the late 2280's, the scope of advances in Warp Field Theory were beginning to be realized. While some arrogant designers, desperate to salvage the Transwarp Drive, thought they could modify the Excelsior Class enough to make their drive work, others knew it would be decades before the advances in theory could even be applied in practice. Starfleet not recognizing the split, went ahead with the refit of the Excelsior in the 2290's, and only afterwards came to the realization that the Transwarp Project had failed.By 2310's, those that had left the Transwarp Project and their inheritors were ready to pursue the next great project. They had designed the Ambassador Class; the ship they had hoped would make their dream come true. The Galaxy Class was designed to be extremely large. So large that it came with a new set of problems, especially with the Impulse Engines. These were later solved with the addition of the Space-Time Driver Coil. However, the dream that was sparked almost a century before was not realized. It had been glimpsed though, and Starfleet was convinced into backing it.
The next tests needed to focus on the actual engine of the future starships. Throughout the 24th century, the double-coil nacelle was successfully tested and implemented on Ambassador and Galaxy class vessels; more powerful m/ara engines developped for defiant and Sovereign battleships; and sturdier, more subspace-friendly hulls were also developped with classes like the Akira and the Intrepid classes. A plethora of ship designs literally exploded within few decades in several design directions at once, providing a large array of engineering data and tests in starship design and performance.By the early 2408, the designers were therefore ready for something bigger. Much bigger. They went for the concept of a mobile starbase, a starship that could match and even possibly surpass in size and power the immense D'Deridex and Scimitar classes of the Romulans.
The Odyssey class was the first step in this direction. But the limitations of the now established arrowhead spaceframe that had been first discovered with the Sovereign class were really starting to show as, the larger such a flattened, elongated ship became, the less efficient it became at warp transitioning and impulse maneuvering;the first one was annoying for deep space assignements; the second one was crippling in tactical engagements with comparable ships that proved more maneuverable like the Klingon Borthas.The engine and power distribution difficulties that plagued the Sovereign class before it could finally get the latest class 9 m/ara and the field tests on the earlier Galaxy Class confirmed from the data of previous ones like the Niagara, Springfield, Challenger and Cheyenne that, the more organic the ship was in shape, the better it made the transition into warp.
So, the design would eschew the arrowhead concept of later designs, pushed to the extreme with the triangular concept of ships like the Prometheus class. They went back to the true saucer form to reflect this, with even more curves, while maintaining a lower hull profile necessary for non-polluting warpfield efficciency. This positioned the new design as the first vessel in the last half century with such a design, and so it was as yet still unnamed even in discussion. The design incorporated an elliptical saucer and angled, curved secondary hull and flattened, elongated pod-like nacelles. The tested end result of organic-like designs as well as advances in warp drive technology proved that the triangular, sharp-angled design was not the only one to consider for future improved vessels.
To compensate for this return to more massive frames without loosing the advancements in warp geometry the flatter, angular frames easily provided, the spaceframe was made with pylons more angled and pushed farther back and with double-coiled nacelles much longer than the original Galaxy class design, thus creating a much more elongated warp geometry around a much less flattened, elongated spaceframe. This had become possible with the advent of much more powerful warp cores like the class IX of the Sovereign class and the much more efficient power distribution available from the gelpack technology, first successfully implemented for computer processing on the Intrepid class.Now it was time for the next generation to start.
The designers had gathered all the data they needed before they could begin on the final designs, still unnamed by Starfleet mandate, to the dismay of the designers (who already had named it the Horizon class, seeing it as the design that would open new horizons in space exploration as well as for starship built). Most of the designers had the feel of the scale for the future vessel though, and the Odyssey, already selected as the next capital ship class for Starfleet, was also appropriately measured toward that ideal. The successful launch and perfomance of the USS Odyssey and especially of the new USS Enterprise made this Odyssey class vessel very popular and thus was in full production as the mainstream capital ship by 2410.By then, designers were ready to jump into something that had even much larger proportions.
The Odyssey Class came into being, designed as a production line vessel. It was a smaller-scaled preliminary version of the future truly intergalactic vessel they had in mind, which the designers had now openly dubbed the Horizon Class. However, Starfleet was still not ready to officially give it a name. In truth, it had been over fifty years in the making. Two generations of starship designers had toiled since the implementation of the Galaxy class, determined to filter out the problems that had come with the size and complexity of that otherwise marvelous design; most of the first group was gone. Most had died, and those who remained were either too old or still held on too tightly to the idea of a Transwarp Drive.
But in 2397, Starfleet had given the word, and the designers were ready to create the pinnacle of almost two hundred years of work, tracing it's routes directly back to the Excelsior Class. When Starfleet gave the project it's official name, they conceded to the designer's wishes and it was finally officially christened the Horizon Class. In 2404 and 2405 the Advanced Starship Design Bureau at Utopia Plenitia started working on the design of the vessel under the direction of returning veteran captain Thomas Eugene Paris, the very man who had been the first living being to break the transwarp barrier. By 2408 all the ship's systems were frozen and they were ready to build.Construction on the first pair of vessels, the USS Horizon and the USS Diamond Star, started in 2408. By 2410, the Horizon was ready for tria runs under the original class designation of Horizon class galactic explorer, while the Diamond Star was kept in drydock as a testbed.
The second and third pair of vessels were commissionned just as the name of the class was changed in honor of the elite Starfleet Division that had been most instrumental in the final defeat of the Borg Collective: Lotus Fleet. Thus was finally born the Lotus class.
Even though the Lotus Class is a young class of starship, Starfleet and the Advanced Starship Design Bureau were keen on using the basic qualities of the old, honored Galaxy design, remove it's weaknesses and improve on it's overall success. For example, two extra phaser arrays were added to the nacelle housings to cover the observed blind spot and weaker firepower of the Galaxy class in the low-aft angles. The same improvement was done on the aft saucer section. These upgrades also included advancements to the latest warp core developped for the Odyssey class, to compensate for the elevated frame latest designs avoided since the discovery of subspace pollution effects. The upgrade made the ship faster and more efficient from a cleaner power source and distribution system, allowing it to achieve speeds over Warp 9.98 for twelve hours without causing the instability between the barrier of Space and Subspace that would have condemned it to the Warp 5 Directive.
Although as elevated as a Galaxy class, the organic-shaped frame was easily twice as long and large, resulting in an overall flatter hull giving the benefit of smaller streamlined shapes despite it's obviously much less "arrowed" shape.During first contact with the Dominion, the Galaxy class USS Odyssey was destroyed, revealing a weakness in the structural design. Around the deflector dish and neck of the Galaxy Class is an extreme weakness to attack. Even though a suicidal enemy vessel attacked the USS Odyssey, this weakness was later proved to be serious under torpedo fire. When work began on the Lotus Class design as an upgrade of the Galaxy one, this weakness was promptly addressed from the start. It was done by redesigning that part of the ship in lower, more angled configuration to deflect any possible impact with the same hull upgrade of ablative armor around sensitive areas that the last Galaxy ships had received for the Dominion war. In addition, the ramming-repulsor deflector pulse developped for the Achilles class was installed to further enhance as a whole the defense against any such ramming or collision when shields would be down, thus giving better survivability to the ship either in combat or in exploring hazardous areas like asteroid or mine fields.
Lastly, as the ablative regenerative armor was added to the design's defensive capabilities, the necessary replicating material was stored in the lowest part of the secondary hull and extended to the entire belly of the ship, literally creating a passive 4.6 meters thick shield underneath it, similar to what is standard on starbase designs against orbital hazards and degrading orbit-forced reentry.
Indeed, the Lotus class is nothing short of a mobile space station in size and intent.
