Re: Traveller and modern electronics
Hmm so it sounds like Traveller military ship armor is like this from the Aliens-verse setting in regards to ship armor?:

Also, I want to emphasize that Traveller armor isn't weak compared to physical impacts it's that KE missiles that accelerate at 10Gs for an hour will explode on impact like tactical nukes. Even that merchant ship's DR 100 will cause a .50 BMG with APHC ammo to bounce off without damage. Traveller capital ships will also usually have a "nuclear damper" a superscience device that prevents the detonation of nuclear weapons within a certain radius of the ship.

As for Bonded Superdense, it sounds like the material General Product hulls from Known Space are made of. Or at least the underlying mechanism seems to work similarly. |

Bonded superdense is a much more moderate sort of super-metal than the GP hull. It can be destroyed by things less than antimatter it's just 14x as difficult to do compared to steel. Traveler ship propulsion is also moderate compared to other kinds of superscience. That Tigress-class does mass 8 million tons like an Honorverse super-dreadnaught but it only accelerates at 2 Gs rather than 500. If I'm starting to confuse you, Traveller ships are traditionally measured in a unit that Gurps calls the "dTon" for "displacement" as it's a unit of volume. Mass is mostly ignored in Classic Traveller. This contrasts with the latest Gurps system called Spaceships which is based on mass and ignores volume. The out-of-print books for Gurps Traveler (based on Gurps 3e and its' Vehicles book) track both.

As for the dton, yeah I know about that. I don't understand why such a unit was used for Traveller. Is there an out-of-universe explanation? |

Re: Traveller and modern electronics
The CT Tigress is 6g - if the GT has a lower acceleration than there is something wrong with the ship design system or conversion.
In answer to the question is there anything heavier - yes. CT S9 states that there are bigger BBs than the Tigress but they are not stationed in the Spinward Marches. |

For other matters liquid hydrogen is a phenomenally low density item and oddities result.

Re: Traveller and modern electronics
The displacement ton is the volume 'displaced' by 1000kg of liquid hydrogen.
The displacement ton is a result of the scale chosen for mapping deckplans. In CT 77 the starship ton was mass - 1000kg. But to map a ship the convenient fact that one ton of liquid hydrogen has a volume of 14 cubic metres meant that a deck plan that has extensive fuel tanks made the 14 cubic metre fit nicely. A square 1.5m by 1.5 m, with a 'ceiling' height of 3m from deck to deck gives a volume of 6.75m - or nearly half a displacement ton (volume) of liquid hydrogen. Using Imperial measurements such as in D&D and GURPS, squares were typically 5' square, 5x5 with a 'ceiling' of 10' gives a volume of 250 cubic feet, two such squares gives a volume of 500 cubic feet - the volume of 1 ton of liquid hydrogen is approximately 500 cubic feet. So it just made sense for the displacement ton (14 cubic metres or 500 cubic feet) to become the standard size of a ship ton. |

Re: Traveller and modern electronics
Traveller ships aren't that big length wise right?
