A spaceship created by Yar Kramer for the purposes of, well, virtually any conceivable purpose a space ship might serve, and thus it has a modular design — hence its name, the Modulus. Generally speaking, it has a design which resembles a paper airplane, but it is capable of transforming into shapes which range anywhere from "one man fighter" to "large enough for a family of six to comfortably live in for a month."

Specifications

The Modulus has a number of different power sources, depending on the needed circumstances: two Dilithium crystals, a small cold-fusion reactor, and a large rechargeable battery.

By way of the transformation ability, the control panel for any given function are whatever the current user feels most comfortable using. If you want to pilot the Modulus using a set up identical to that of a Boeing 747, one will appear in front of you as soon as you sit down. If you want to operate one of the gun turrets using a Playstation™ controller, you will get one.

The computer in Yar's Grendel armor (see under Weapons and Abilities) has a direct link to the Modulus, and is capable of remotely contacting the ship (and even piloting it with a reasonable degree of skill, or at least recalling it to his location).

The Unlikely Drive

Also essential to the Modulus is an Improbability generator; it generates a finite amount of improbability by way of the classic setup of a Bambleweeny 57 Sub-Meson Brain with its logic circuits connected to an atomic vector plotter suspended in a strong Brownian Motion producer (say a nice hot cup of tea) — except that the tea and the plotter do not physically exist, but are instead simulated in a second Bambleweeny 57 Sub-Meson Brain. The idea that this could possibly work is ridiculous; however, it has a finite improbability of success, and Improbability generators of all description must work retroactively if they're going to work at all. Yar has dubbed the whole The Unlikely Drive.

Its primary stated function is to open up a portal leading to the destination of the Modulus and crew, and then closing it again. It also governs the ship's transformation capability, the functions for changing control schemes, the remote-piloting function with Grendel, and in a pinch it will also function as a last-minute deus ex machina.
