Apparently, we need to design at least 3 machine guns. So go ahead, though I propose you use modifications of existing guns, in order to save on design slots.
((Have there been any changes in unobtanium stockpiles?
Also, is there a central list of designs somewhere?))
1. P Class airship -Balloon volume: 31 000 m
3 -Total Lifting Capacity: 34.5 tons (Note: Includes weight of the frame)
-Standard Flight altitude: 2000-3500 meters
-Effective Payload at cruise altitude: 20 tons
-Maximum altitude: Almost 8000 meters, or more. (Requires dropping of ballast, and extremely low payloads. <5 tons)
-6 Armored Engine cars, utilizing our most effective/most fuel efficient engine:
-Multiple Heavy machine gun turrets. Probably the modified Belt 12's.
-Note: A multipurpose airship, capable to make variable altitude flights. Has the carrying capacity to serve as a bomber, but can also do scouting and other tasks. Most important parts have been integrated into the balloon.
2. Modified Belt 12's so they can be easily mounted on planes or airships. (Losing the ability to be manportable, but lighter)
3. Early experiments with rocket artillery
4. Modify our fighter plane to use these modified belt 12's
A. Prototype factory (A factory designed to churn out prototypes)
B. Prototype aircraft factory (A factory designed to churn out prototypes of all that flies)
C. Shipyard.1.Airship
2.Modified Belt 12 (Aircraft version)
3.Rocket artillery
4. Modification of fighter craft
