I posted this cover two years ago, but figured it was worth a repost after tracking down the original art.
Freas is famous for his comic space adventures but I don't think he gets enough credit for how convincingly he paints hardware. You can feel the weight of the gear in this picture. While I couldn't find evidence that he was inspired by the Italian divers of the Decima Flottiglia MAS, a man can dream.
He said of this painting:
> As I have mentioned (often!) before, one of the greatest pleasures for the illustrator is to have an author tell him that he has caught in his painting exactly what the author had in mind. When the author is also an accomplished painter—and backs his praise with hard cash to purchase the original ... well, you begin to believe him, y’know?
The original art is collected in Frank Kelly Freas: The Art of Science Fiction (1977).
