Ah--she's definitely rigid airship-like, similar (if the forward section) to Joseph Speiss's rigid airship (see: https://en.wikipedia.org/wiki/Joseph_Spiess and [video: https://www.youtube.com/watch?v=cP3nrDUb3es ]), the only French rigid airship, which had perhaps 12 sides, unlike the 8 sides of the VSM-40M / SHEFEX-II's forward section. Also:

I see that the rocket tested sharp-edged re-entry vehicle and control surface shapes (see: https://www.google.com/search?sxsrf...HapGCq8Q4dUDCA0 [Dr. Marc Murbach at NASA has also tested such sharp-edged, reinforced ceramic shapes on sounding rocket and Minuteman ICBM practice flights]). They will facilitate highly-maneuverable glide re-entry vehicles, aerograv-assist spacecraft for planetary missions, and hypersonic-cruise aircraft and missiles.
