We did so using fiberglass and urethanes, using drawings provided. The stern section is still a matter of security so for public release we placed a 'button' on it in place of any type of propulsion assembly. All details were laser cut.
Hatch detail is plentiful and subtle.
Panel lines are laser cut in this pre-paint image. Note the clear 'button' supplanting any propulsion renderings. That was done under orders and was not left to our discretion.
