The HK-55 Imperial Troop Dropship was a craft used by the Empire to transport Troops through atmosphere to a battle, post, or other important positions. Because of its size, this relatively small transport ship was able to move swiftly and nimbly though battlefields. Due to its size, though, it was only able to transport 6 troops comfortably. The ship boasts no weapons, except for it's lone proton bomb. Weapons would only slow the dropship down, so Imperial engineers decided to only use one big bomb. This allows for a swift, 'Get in, Get out' battle plan.
HK-55 Dropships are usually launched from Star Destroyers hanging in mid orbit. They fly down, drop off their load, and return to the Star Destroyers to reload more troops. These transports are well known to deliver reinforcements so quickly, 'It's like The troops were already there.'
Great job! The whole design and shape just looks like it was in the movies! It really reminds me of the Theta class shuttle, just by looking at the wings and cocpit. And that extra bit at the 'Nose' is a great touch!
