Here's the Stingray papercraft based on a submersible warship from the 1960s scifi children's tv show of the same name. The Stingray is a highly sophisticated combat submarine used by the WASP (World Aquanaut Security Patrol).
Stingray was created by the renowned producer/director Gerry Anderson, the one who created Thunderbirds. Originally shown in 1964, it was the first British television series to be filmed in colour. This Stingray papercraft was designed by Gary Pilsworth.
