Spacecraft
Taelons use the same bioslurry for the construction of most of their spacecraft as they do for the construction of their buildings. The craft they use vary enormously in size.
Taelon shuttles are small craft used for transportation across space. The true range of the shuttle is unknown, but one such vehicle makes a journey to Mars in season 1, another, carrying Lili Marquette, travels at least as far as Alpha Centauri (about 4.5 light years), and another, flown by the Taelon Bel'lie, may have made a much longer journey, possibly even from another galaxy. The shuttles are extremely fast by the standards of Earth aircraft, and, from the second season, are armed with a form of energy cannon. The craft, though quite sturdy, are not indestructible, and can be destroyed in crashes or by enemy fire (in one instance, the resistance are able to use a large shoulder-mounted weapon to destroy a shuttle).
The Taelon cruiser is a much larger vessel. Designated as M'Thraa class, these ships are used for heavy combat, though are not sufficiently powerful to engage the largest Jaridian warships. They are used in support of the Volunteer service, a Taelon program for humans who otherwise have nowhere to go, such as homeless people or high-school dropouts who don't live with their parents. These craft are much larger than shuttles: though their exact size is indeterminate, they appear to be between 50 and 200 metres long, usually appearing closer to the lower end of that range. It is possible that there are several, very similar designs with different sizes, though this would make them subject to the scaling paradox (items cannot simply be scaled up or down, as the ratios of strength and their properties will be altered)
A single Taelon scoutship, originally belonging to the Taelon researcher Ma'el, is seen in the third season episode "Time Bomb". Its total dimensions are not revealed with certainty, but it appears to be of a similar scale to the M'Thraa-class Taelon cruiser. The ship is supposedly long-range, but equipped with minimal armaments. Ma'el's ship is equipped with several stasis units though it is unlikely that these are standard aboard other craft of this design, especially as the stasis units appeared to be for human use: Taelon stasis beds appear in season 4 and look quite different.
While most Taelon spacecraft, such as their shuttles and cruisers, are created from the same material as their embassies, there is a notable exception in the Taelon Mothership. While this vessel had an appearance more consistent with other Taelon craft in season 1, in season 2 it is redesigned to be composed of translucent energy currents — more closely resembling the Taelons' energy form itself, and remains in this form until the end of the series. These translucent energy currents are termed "Virtual Glass". In season 4, the mothership is revealed to be shrinking, as the Taelons shut off sections and reclaim their energy for their conservation efforts. The mothership is nevertheless a gargantuan vessel, big enough to be seen from orbit. It is confirmed in the season 4 episode "Dark Matter", that the ship still maintains at least 153 decks, suggesting an overall size of several kilometres. The mothership is a unique vessel, and is the only ship in the Taelon arsenal powerful enough to fight a Sokara-class Jaridian cruiser. The Taelons are able to upgrade its weaponry in season 4 so the final armaments and capabilities of the mothership are unknown.
The mothership is equipped with dozens, if not hundreds of shuttles within a vast landing bay. The ship may also house the cruisers seen in the series, though this is not certain: while the mothership's hangar should be sufficient to house several such craft (especially given the indeterminate sizes of both the cruisers and the mothership itself), and anecdotal evidence from the episode "Second Wave" suggests that the cruisers may be either aboard or externally docked, there is no incontrovertible evidence for it. The mothership also acts as a lifeboat for the Taelon people. Within it are a stasis deck, where the remaining Taelons can be preserved when their personal energy supplies dwindle to near-death. There is also a chamber filled with Taelon embryos in stasis, awaiting a renewed supply of core energy. The fate of these embryos is not known.
