This is an airship I worked on today.
The Royal Gunship is a converted transport ship for VIPs and royalty, that is now a functioning mobile airstrip for small military aircraft. It's the first ship in a fleet I'll be making.

Specifications
Crew: 6 Gunners, 2 Pilots (And Pilots and Crew Members for additional aircraft that may land on the ship)
Weaponry: 6 cannons (Dispensers) on the port side, 6 cannons on the starboard side
Transport Capacity: 5 small aircraft, or 2 medium aircraft (Might be able to transport a larger one on it, but I wouldn't bet on it)
Equipment: Enough food and equipment to sustain a skilled group of 9 for 6 months, as well as seeds to last longer than that.

(Sorry the windows look a little funny in the texture pack, it's a custom DokuCraft I use, they look weird in with Connected Textures on, and weirder without.)
