The Juggernaut is somewhere in between the shape of a horseshoe & a big C.

The Millennium_Falcon sure has a unique shape. http://starwars.wikia.com/wiki/Millennium_Falcon,  www.starwars.com/explore/encyclopedia/technology/millenniumfalcon

This mysterious underwater shape is very intriguing.

Underwater or in the mountains, even in the desert.

JUGGERNAUT VISUALS
Really, any kind of big ship similar to the ones depicted in sci-fi movies would do.

Sure the Prometheus movie could have been better, but like Alien in 1979, crashed & abandoned ships on various planets makes for an interesting part of a larger story.
