Taking the NASA concept for solid skin vacuum airship and developing a modular, flexible airship system with echos of my Pathfinder Village Construction System.
Would enable long distance exploration, scientific research and heavy payload delivery utilising large scale PV array and flexible loading system.
The unique V shape is designed to allow addition\subtraction of tank levels and the internal segments can be extended\removed to suit payload\mission requirements.
Prefab units for buoyancy tanks will fit in BFR and be assembled at Pathfinder Spaceport
(Any resemblance to Architects plan tubes is purely co-incidental :))
