From my original design notes:
"Both the Trepida MBT and Astrin APC are designed to work in conjunction with an RDA (Rapid Deployment Aeroshell) allowing them to be quickly inserted to a planet from orbit. The RDA fits four of these vehicles (in any combination) around an ECM spine that forms a sort of spindle on the RDA delivery vehicle. The conical aeroshell surrounds the docked AFVs in four petal sections.
Once the RDA vehicle descends to a safe maneuvering altitude for the AFVs, the petals blow away, the AFVs are released for free flight, and the RDA vehicle climbs back into orbit, returning to the deploying vessel. The RDA vehicle is unmanned."
This vehicle system was a standard in the Traveller universe. I did these profiles for Digest Group's "101 Vehicles", but I think both Bryan Gibson (sabakakrazny.deviantart.com/)
and Tom Peters (drell-7.deviantart.com/)
were more in the know on this vehicle system.
Original was pen and ink, circa 1988.
