DeLuna 445 heavy spacecraft C

The DeLuna 445 heavy spacecraft "C" is a single-jump class 2 CE drive developed by DeLuna Ethermotive Company and sold from 419OT to 431OT. Following the development of the DeLuna 445 heavy spacecraft "D" and the DeLuna 889 Tempest model drives (in 424OT and 426OT respectively) which dramatically improved upon the "C" design, the "C" was gradually phased out of production, with most ships (such as earlier Sagi-class vessels) reliant upon the "C" transitioning to operate off the newer "D" model; higher-end ships were outfitted with the 889 Tempest.

The naming of the drive model refers, like most DeLuna drives, to the ratio of space extended during operation to space compressed during operation; the "C" model sports a ratio of 4:45 extended-compressed. Because this ratio is a slight increase over a perfect 1:11 ratio, jumps often slightly overshot distances specified by common travel routes, a quirk which was known to cause navigational delays, even with a sophisticated navigational computer.

The "C" model drive was notorious for its high power draw and comparatively low power output as well as slow charging speeds and long cooldown periods between uses. Its fast release rate meant that its jumps were often uncomfortable, and subjected passengers and cargo to lurching turbulence. Despite its drawbacks, many ships were outfitted with the "C" model drive during its production due to its ease of maintenance (which it needed frequently) and low pricing.
