The Omega-class destroyer is a fictional vessel used by Earthforce, the military branch of the Earth Alliance, in the science fiction television series Babylon 5.  The CGI model of the ship made its first appearance during the opening scene of the opening episode of the second season, "Points Of Departure", which was initially aired in the United states on the 2nd of November 1994.

It also appears in the later, and short lived, Crusade television series, the TV movies A Call to Arms and In the Beginning as well as the The Lost Tales(the first in a now aborted due to funding issues anthology series which were to be released on DVD) plus a number of written short stories and novels based in the same fictional universe.

Origin And Design

As with most of the computer generated models seen in the first 3 seasons of Babylon 5, the Omega was both designed and built by a member of Foundation Imagining.  In this instance, Paul Bryant who co-founded the company in 1992 with partner Ron Thornton.

The model was referred to as the “Aggie” in house due to the name of the first ship to appear in the script, the Agamemnon.  The original, fully-detailed version contained over 250,000 polygons although it was designed so that layers of detail could easily be removed to reduce the polygon count.[1]  This was necessary due to the limits of the computer systems at the time, primarily the amount of RAM (Random Access Memory) they could use.  Removing detail (and thus the number of polygons) would permit reduced rendering time.  This stripping down process was only required when a large number of models appeared in an animated sequence (such as the season 4 episode, "Endgame") and was usually limited to the vessels appearing in the background.

The closer adherance to real physics with regards to how human (not alien) vessels would be portrayed in Babylon 5 was introdcued by Foundation Imagining and is the why a number of models such as the Omega included a rotating section to create artificial gravity. Originally the design also included a complex engine design, which was necessary to accurately portray how such a massive spacecraft, with a large rotating section, could manouver.

“Originally the engine section was a complex gimballed affair because when turning a large centrifugal mass the turning thrust axis is not intuitive.  For example if the centrifuge is rotating clockwise, to turn the ship to port the thrusters should be pointing down thrusting upwards.  I explained this to the guys and they looked at me like I had two heads.  I think it was Ronny who said 'Look, just stick some big engines on the back and walk away'.  We were under a time crunch as always and that's just what I did." — Paul Bryant, Source: B5Scrolls (2008)

The final design which Bryant used was partially modelled on WWII pulse engines similar to those seen on the German V-1 flying bomb.

The Omega was also designed to appear both un-aerodynamic and imposing.  Part of this approach was the inclusion of what later became known as the 'hammer head' by some fans of the show.  Namely, the 'cheeks' on either side of the forward facing fighter recovery bay which were inspired by the smoke deflectors (or lifters) that appeared on some later steam locomotives


Designed but never used

The original description of the vessel within the script handed to Paul Bryant implied that if one of these ships appeared in your system you would be in trouble.  So part of the idea behind the design of Omega was to make it appear visually imposing and carry enough firepower so it could erupt with projected destruction.  However, a number of these design elements which can be seen on the Lightwave model were never used in any animation sequence in which it appeared.

“The turrets on each forward cheek were just there to get your attention, they were the 'light' weapons. :) . . . . . . the dual Big Ass Cannons under the ships return bay that were supposed to launch gigaton class mines – yes those things were there for a reason.” — Paul Bryant, Source: B5Scrolls (2008)

The 72 red hatches that can be seen along its hull were missile compartments.

“ The detail was designed for a 19th century broadside effect.  You know, camera scraping down the side of the Aggie as all the hatches open sequentially just like every swashbuckling movie you've ever seen.  Then open to a wide shot as the entire ship's side erupts in flame and missiles.” — Paul Bryant, Source: B5Scrolls (2008)

Located at either end of the models central rotating section are a series of fighter launch bays designed to work in a similar way to those housed in the Babylon 5 space station, known as Cobra Launch bays.  Namely, the centripetal force created by the rotating section would essentially push the fighters out.

“On the centrifuge, if you look closely in some shots, you can see sealed Starfury launch bays.  I wrote a whole tactical description of how Starfury flights were deployed in battle.  If the launch was defensive then as the centrifuge rotated the 'Furies' were deployed evenly around the ship by releasing them at regular intervals.  If it was an attack then they were released at a specific degree of rotation closest relative to the target” — Paul Bryant, Source: B5Scrolls (2008)

The exact reasons for the omission is unclear.  Though it may be related to the fact that J. Michael Straczynski, the creator, main writer and executive producer of Babylon 5 usually (or at least in the first three years of the show) deferred to the designers and animators when it came to providing detailed functionality to a model, and never provided a detailed list of specifications.  That, and all but one of the major battle sequences involving the Omega design took place after season 3 (the last year Foundation Imagining worked on the show).

Controversy

Due to the Omega’s rotating section and its similarities to that seen on Syd Mead's design of the Leonov.  A fictional Russian space ship that appeared in the 1984 movie, 2010:The Year We Make Contact.  Over the years many claims and counter-claims regarding this has appeared on various intenet discusion forums, blogs and sci-fi based sites.  When asked for an explanation, J. Michael Straczynski stated on the rec.arts.sf.tv.babylon5.moderated newsgroup:

“The ships on 2010 and Babylon 5 operate out of the necessity of travelling without standard SF artificial gravity.  These designs have been discussed among scientists (in general) for ages; so there's no intention to be close to 2010, but when both are based upon the same scientific principles, there will be echoes.  Form follows function.” — J. Michael Straczynski, Source: jmsnews quote archive (1995)

This did little to convince those that believed it was a direct copy.  Some argued that although both rotating sections provided the same function (creating artificial gravity), there was no practical reason for the obvious, and near identical, similarities in form.  However, years later Paul Bryant shed light on the subject. It was indeed a mischievous and blatant homage to the Leonov (which he did not include in the Cortez, another model with a rotating section that he designed at the same time), and Straczynski had apparently never asked him before dismissing the similarities.

“Yes, I can confirm that I ‘lifted’ the centre section off the Leonov in 2010 for the centrifuge.  That's why the profile is exactly the same.  I was feeling mischievous, so I added this little nod to the design.  I thought someone was going to spot it immediately but no, it was years before anybody called me on it (it would have been an easy fix to change the profile).” — Paul Bryant, Source: B5Scrolls (2008)

Appearances

Shortly after his arrival to command the Babylon 5 station, at the start of season 2, Captain John Sheridan (played by Bruce Boxleitner) describes the role of the Agamemnon (the Omega destroyer he had previously commanded) during an interview by an ISN reporter, in the episode "And Now For a Word".  He mentions it was one of the first Omegas to be built after the Minbari war and that their job was part military patrol, part diplomatic mission, visiting many in the non aligned worlds (smaller alien races), putting in an appearance and helping keep the peace.

The patrol aspect of its mission appears to be why, in the earlier season 2 episode, "All Alone In The Night", General Hague (played by Robert Foxworth ) was able to call the Agamemnon (which is in the area) to help in the search of the captain who had been abducted by a group of aliens named the Streib.  This episode states it is the fastest vessel in the area its are used effectively against what appears to be an advanced race.  Its ability to create a jump point to enter hyperspace (the method used in Babylon 5 to cover great distances) is also demonstrated.

By the season 3 episode "Severed Dreams" it becomes apparent, from the number appearing onscreen, that the Omega design is the primary capital ship used by Earthforce at that time (the others being the Nova and the Hyperion). Its ability to carry Starfury fighters is also shown.

The dominance of the Omega design within Earthforce is confirmed throughout the later episodes of season 4 beginning with "No Surrender, No Retreat", which depicts what is essentially an earth civil war .  Further episodes of the fourth season state it carries life pods, is not capable of flying in atmospheres and that its rotational section reduces its manoeuvrability and energy efficiency compared to ships without one.

The television movie, "A Call to Arms", set four years after the final year of the Babylon 5 series, shows the Omega is still the most ubiquitous capital ship being used by Earthforce – during the large battle sequence against the alien race known as the Drakh.

The second of the Lost Tales stories shows, in a dream sequence, that the Omega design is still being used approximately 30 years after the final year of the Babylon 5 series.


Ship Specifications

This is a subject, relating to all the ship designs seen in Babylon 5, that has caused a great deal of, sometimes heated, debate within sections of the shows fan community.

While some technical details for the Omega were released in publications such as the Babylon 5 Security Manual and the B5 CD-ROM reference guide, most were considered to be incorrect by some fans who closely scrutinised the images of the vessels seen in the show.

A number then went on to publish, on various web sites, sometimes highly detailed and imaginative facts and figures based on their own observations while occasionally incorporating officially-released details.  This has essentially resulted in no universally-accepted technical information appearing for the Omega on any fan, reference or sci-fi internet site.  Though some are more widely quoted than others.

For example, in the show the crew numbers of an Omega destroyer is mentioned on three occasions.  547 (season 4 episode, "Intersections In Real Time"), a little over 1,000 (season 4 episode, "Endgame"), ) and 347 (Crusade episode, The Needs Of Earth).  Although no explanation is given for the differences, a quite logical consensus was generally reached among interested fans that it depended on the deployment of the individual ships.  Though the actual crew numbers that appear on fan sites is often none of the above.

The ship's length is often stated to be 1714.3 metres.  This is in fact the only officially-released number quoted for the Omega destroyer to appear on most internet sites.  It was created by Tim Earls, who joined Babylon 5 in season 4, as part of a size chart he was asked to create by the shows executive producers, shortly after becoming the Art Director for Visual Effects, at the start of the fifth season of the show.  (Not the CGI Director which is another incorrect detail that is sometimes published on various sites.)

However, this length for the ship is often quoted, without caveats, along with lists of other details that are purely fan conjecture (for example, that the Omega can carry 36 Starfury fighters).  This figure originates from a fan's direct observation of a fighter launch sequence viewed during the season 3 episode, "Severed Dreams".  In fact, the relevant scene opens after the launch sequence had already began and was left while fighters were still leaving the two vessels that were shown.  The largest number viewed during the sequence was 34 which was launched from the Omega named the Churchill.

Design Variants

Advanced Omega Destroyer

One variant of the Omega design was seen during the season 4 episode, "Between The Darkness And The Light".  A battle group made up of what was referred to as Advanced Omega Destroyers were deployed against, and subsequently destroyed by, a number of White Stars that had been dispatched to engage a previously-unseen type of Earth vessel.

During the season 3 episode, "Messages From Earth", it had been revealed that humans had taken samples from a recently-discovered inactive Battle Crab, (an organic vessel used by the Shadows, one of the highly advanced and fictional ancient races that were collectively known as the First Ones) for study.

During the episode "Between The Darkness And The Light", the viewer is shown the result of the organic technology being retrofitted onto the hull of the standard Omega design.  The character of Susan Ivanova (who was commanding the force of White Stars) expressed surprise at how quickly this was achieved.

These advanced destroyers also carried a number of apparently unmodified Thunderbolts (a class of Starfury fighters) and had received some weapon upgrades as the turreted particle pulse cannons located along the hull had now been replaced by some form of unspecified particle stream weapons.

Like the Omega destroyers technical specifications, more or less all the various details relating to this variant that appears on the internet including how, when and why it was developed was developed over time by a small number of fans creating supplementary material for the design since no 'official' information existed.

Prototype

The series strongly implies that the production of the Omega destroyer began after the Minbari war, though no specific year was ever mentioned.  This conflict took place around 2248, a decade before the first season of the show. However in the television movie, In The Beginning, which focused on that war as well as the events leading up to it, a number of Omega destroyers appeared. Although a fan-based theory that these were prototype ships was developed to explain this apparent error in continuity, the reality was that CG models were often recycled from one episode or TV movie to another and the inclusion of these Omega destroyers was likely an oversight.
