USS Republic (from Star Trek: Republic)
« on: March 15, 2012, 07:14:26 PM »
A few thoughts behind the ship in the story (which can be found here: http://www.subspace-comms.net/index.php?topic=4192.msg125942#msg125942 ).

Republic is a Korolev-class starship, a heavy cruiser slightly larger and more robust than an Excelsior. At the time of the story, she has been commissioned in Star Fleet service for nearly four decades and is one of several ship classes (including the Ambassador-class) that preceded the introduction of the Galaxy- and Nebula-class ships.

The Korolev-class is mentioned in canon, but very little is known about it. During my many internet spelunking expeditions, I came across a website known as the Advanced Starship Design Bureau. This is where I first saw what the Korolev-class might look like; and it gave me the inspiration for this story.

Here is what the USS Republic (NCC-51497) looks like, gentlemen. Based upon the work of the good men and women at ASDB.

These schematics were NOT created by me; they are the work of Jason and Kris (who I believe is also known as Reverend) (among others) from the ASDB (Advanced Starship Design Bureau).

Their work (and other peoples work) can be found here ( http://www.trekships.org/index.htm ) so take the time to browse through the site and enjoy the sights (no pun intended).

And here are three size comparison charts with both canon and ASDB ships (side, front, and top):

Ok. I had an idea for the story and now I knew what Republic looked like, and how big she was. But that wass literally all that I knew about the class. So, in the finest tradition of authors everywhere, I made up the stats on the Korolevs. I decided that they were intended to replace the Excelsior-class vessels as modern workhorses and appeared on the scene after the introduction of the Ambassador-class.

Based on the drawings, I decided that she mounts nine Type IX phaser array strips (two dorsal on the saucer, three ventral on the saucer, one ventral on the engineering section, one dorsal on the engineering section, and one each port/starboard on the warp nacelle pylons). She is also equipped with five photon torpedo launchers, four mounted forward (two banks of two) and one aft, with a total loadout of 200 torpedoes and probes (typical load is 150 photon torpedoes and 50 probes). The Korolevs torpedoes launchers are unable to fit the latest generation of quantum torpedoes and are restricted to conventional photon torpedoes. The launchers are restricted to a single torpedo per tube and each tube is fed from a five-torpedo ready magazine. Each tube requires four seconds to reload (from the ready magazines), giving the class a sustained fire rate of one torpedo a second from its four forward launchers. Once the ready magazines are emptied, the ship requires 30-seconds to reload from its storage magazines.

Her original shields were on par with the Abamssador- and Excelsior-class ships, but after Wolf 359 she was refitted with newer generators bringing her defenses up to the same standard as a Galaxy or Nebula.

The Korolev-class featured two separate impulse engines, mounted on the saucer section just inboard of each warp nacelle. A distinct improvement over earlier impulse drive systems mounted on the Ambassador- and Excelsior-class ships, these provided the Korolevs with the capability to 0.9c at full power, although she normally cruises at 0.25c to minimize fuel consumption and to avoid relativistic effects. Maneuverability was also improved over the older ships.

These ships differed from more traditional starships of the time in that their warp core orientation was not vertical, but rather horizontal, running fore-to-aft on Deck 6 aft.  The change in orientation allowed the use of a longer and more powerful core than would normally be available.  Like most modern Star Fleet designs, the Korolev-class were equipped with equipment to jettison the core if necessary; in this case by blowing off panels on the fantail and ejecting the core aft, rather than down.

The LF-23 warp engines on the Korolev-class were modified versions of the LF-17s fitted to the Ambassadors. Many in Star Fleet (at the time that the design was debuted) considered the new vessels to be far overpowered for their size and mission. Indeed, although the new cruisers were barely more than a third as massive as the Ambassadors, their matter-antimatter warp cores were able to generate 69.7% of the larger explorers total power output. The engineers who designed the Korolevs knew exactly what they were doing, however. The sheer mass and volume of the Ambassadors meant that those ships could only be towed by another Ambassador; not even the current generation of fleet tugs in Star Fleet inventory was able to retrieve a badly damaged Ambassador at warp.

But the Korolevs, using those overpowered warp nacelles and a new generation of more powerful tractor beam generators (the most powerful fitted to any Star Fleet vessel prior to the introduction of the Galaxy class), was designed to be able to extend her warp field and take an Ambassador in tow at speeds of up to Warp 6 for up to eighty-four hours.

Originally rated for a cruise speed of Warp 6 (a speed that the cruiser can maintain indefinitely), trials and field tests of the prototypes revealed that these new ships were able to sustain a much higher speed for far longer than existing ships: Warp 7 for as long as twenty days, Warp 8 for up to a week, and Warp 9 for more than 48 hours. Maximum rated speed was an impressive (for the time) Warp 9.5 and the Korolev’s once again proved that endurance they had in spades, with the ability to sustain that speed for two hours.

Unfortunately, the overpowered, overbuilt engines proved to be inefficient and costly to maintain, requiring 128% more man-hours than the warp drives of the Excelsior-class. Furthermore, it was soon discovered that the stress and strain placed on the warp coils gave them an effective service life half that of either the Ambassadors or Excelsiors. This explains, in part, why the Korolevs did not fully replace the older Excelsiors in Star Fleet inventory. Although there have been several refits proposed that would replace the LF-23s aboard these ships with newer and more efficient warp drives, the difficulty of refitting these ships engines and power plant has scuttled those proposals every time.

The Korolevs featured a greatly reduced crew in comparison with the Excelsiors, relying more on automated systems and computer-assisted diagnostics. The ship requires a complement of 382 (41 commissioned officers, 87 non-commissioned officers, and 254 crewmen), with space for an additional 118 passengers or mission specialists. The crew live on 18 seperate habitable decks. Under emergency conditions, a Korolevs life support system can handle up to 1,000 total personnel for a minimum period of two months (under extreme conditions, nearly 2,000 refugees can be packed aboard ship, but the life support, food replicators, and waste recycling systems would be strained to say the least).

The vessel embarks a dozen shuttle craft (mainly Type 6) in four seperate bays, plus a warp capable Captain's Gig in a ventral hull dock located beneath Shuttle Bays 3 and 4. Scientific research labs are considered adequete for most missions, but the latter Galaxy- and Nebula-class ships proved far more capable in that role. The ships were equipped with the best sensor arrays available at the time and that aspect of the class has been constantly updated.

Six transporter rooms (four standard and two emergency) are standard, along with two cargo transporters. Refits have provided with Korolev-class with two holodecks, plus a holographic shooting range for Security personnel. Three tractor beam generators are fitted, one forward along the ventral hull beneath the deflector dish, and two astern (dorsal and ventral).

The Korolevs were designed for long duration patrols and exploration, and each carries sufficent supplies and fuel for a five-year mission. There are also four cargo holds, with roughly 50% more available internal volume for emergency supplies and parts than an Excelsior.

Like the Excelsior- and Ambassador-class ships before them, the Korolevs were not equipped with the independently operating seperations of the later Galaxy-class vessels, relying instead on more conventional lifeboats and emergency transporters.  These ships are incapable of a controlled landing on a planetary surface; however, much like their Constitution-class forebearers, the Korolevs can operate within a gravity well and atmosphere for limited periods of time (albeit at great strain to the engines and structural integrity field).

Several of these ships are present in Galaxy Exploration Command, although the lion's share are part of the so-called Blue Fleet, the Andorian contingent of Star Fleet command. The vessels of the Blue Fleet are extensively used to protect and defend Federation member systems and colonies and are only seldom used for general exploration. Although being replaced by Akira-class vessels in the Blue Fleet, the toughness, strategic speed, and research capacities of the Korolev-class have resulted in more and more of these vessels being dispatched as research vessels in situations considered too dangerous for the new Nova-class science vessels.

The Korolev-class is certain to remain a signifcant member of Star Fleet for decades yet to come.


Anyway, that is my take on the Republic. I wanted to start this new thread to find out what you guys think of the ship itself:  is it too powerful or too weak; too fast or too slow?  Does the horizontal warp core work?  Does the design history of my vision of this class fit into the Trek universe.  Tell me your thoughts; I welcome any and all open honest criticism and critiques.

Thank you,

So let's get this party started, shall we?

Doesn't seem unreasonable. There's certainly enough room in the ranks for ships like this. The only thing that stands out to me is that the oversized warp core and maintenance intensive warp drive seems at odds with it being equipped for extended periods of independent operatons.
Steady on.

Well, the Excelsior-class was designed for a 10-year deployment between refits, correct?  That would still give the Korolev-class a good five years before the warp coils need replacing (in a perfect world).  But that also gives us a reason that the Korolev didn't replace the Excelsior; the added maintenance hours made the class less than desirable among Starfleet Command, keeping the old Excelsiors in service as new lighter designs, without the capacity for heavy duty towing of the Korolevs were introduced.  (i.e., designs like the New Orleans-class).

I'm not so much concerned with the service life of the engines, apart from how it places an upper limit on the length of a deployment. I'm concerned with it both having an atypically powerful warp drive for a ship its size—which I must presume consumes more fuel than is typical for a ship its size—while at the same time carrying five years' worth of fuel and supplies. Mostly the fuel part, although a maintenance intensive warp drive would presumably require a lot of spare parts.

I should probably point out that I'm not saying that the five year time frame is necessarily unreasonable: I don't recall any comparable canon number for any other ship class (there are presumably some in the tech manuals, but I've never read any of those). All I'm really going on is that five years was the time frame the Constitution operated with, and it was purpose built as a long-range exploration ship. I just brought it up because you emphasized both engine performance and operational endurance as strengths of the class, and in my mind they are one another's inverse.
Steady on.

Understood.  And you are quite correct that it is a concern.
