Marvel Milestones: Captain Britain, Psylocke & Sub-Mariner #[nn]

In "Sub-Mariner Crashes New York Again!!!", Namor takes matters into his own fins when four U.S. battleships vanish under suspicious circumstances. Investigating a submerged Nazi U-boat and shadowy divers, he stays close to New York Harbor to prevent sabotage during the launch of a new warship. When the vessel begins to sink mid-launch, mysterious aerial subs intervene—lifting the ship back into dry dock before vanishing. In a defiant letter to officials, Namor declares the sabotage was no accident, reveals he knows the culprits, and warns he’ll deal with the Nazis himself.
