A combination of titanium, stainless steel and a carbon-based polymer, Titanocarbon armor is an extremely durable and lightweight alloy that is used as chiefly as defensive plating aboard interstellar warships. Though its defensive abilities are severely compromised against thermonuclear warheads, it nevertheless functions as an adequate countermeasure to rail-cannon weaponry. It also conducts heat very well, meaning that it can protect against the thermal effects of a nearby nuclear detonation, to an extent. The strength of a plate of titanocarbon armor is determined by its thickness. Starfighters typically are plated in 25 millimeter- thick armor, whereas large capital-scale ships can boast a thickness of up to 45 centimeters as a matter of course.
