Ever since the first spacegoing vessels have left their home planets, the issue of heat buildup has been an issue. Thermal radiation can easily build in ships due to engine fire, weapons use, and general use of onboard systems. Due to the nature of the vacuum of space, though, this heat does not easily bleed off and so without suitable radiators ships overheat, either killing the crew or disabling the ship's electronics. To stop this, passive radiators of many sorts have long since been built into spacefaring ships of all races. Both Y'ghatai ships and their human civilian counterparts have large external radiators to dump their excess heat into space quickly. Human military vessels use a mix of external radiators and ceramic plates, the latter of which radiates heat less efficently but ar
