Taking shape with some added details, I am currently redesigning the engines and here I have the ship with landing gear extended. you can see (just) the 6ft tall crewman..
The Britannia is from the animated Anime film “Lensman: Secret of The Lens” Directed by Yoshiaki Kawajiri released in Japanese in 1984 and later released in English in 1990 -1, (why the delay ? ) but I loved it when I saw it first and unlike me when it comes to most adaptations I like the film version of the ship more than the ones described in the books by E.E.Doc Smith of the same title which was cigar-shaped. The ships in the novels, are for me are visually uninspiring and therefore ultimately forgettable, at least from my point of view, I have seen one great model made in CGI based on the book’s description, but I must confess did nothing for me as an overall design.
I like this sleeker design more than what was described in the books
