Steel Shark (1)

Golden Age Origin
The Steel Shark was a deep-sea raider and pirate responsible for sinking and plundering ships near the island of Monango as well as kidnapping Jane, the daughter of the governor of Monongo. The Steel Shark's pirating and kidnapping get the attention of Naval officials who send Leut. Jones to rescue the captive girl and bring the undersea pirate to justice.

The Steel Shark's submarine was equipped with high-tech weaponry such as flux-ray-guns and communications tech such as video phones called a fluro-vox.
