This is Captain Daniel "Mad Dan" Rodgers' submarine, the Titleist
. He was an American naval commander before The Exchange
and continued to captain his nuclear powered, ballistic missile armed submarine in the years following. As much of the world flooded due to dramatically rising temperatures, inland seas formed and those previously landlocked became accessible from the ocean. Mad Dan and his crew pilot and maintain the massive submarine, and use it to scour the ocean depths for valuable resources.
Being a member of the largest class of submarines ever built and originally commissioned as the USS Alaska due to that fact, the submarine was originally intended to replace its aging ICBM carrying counterparts. The 240 meter long vessel carries twenty ballistic missiles in launch tubes in its sail, as well as a variety of forty-six smaller missiles in vertical launch tubes near the bow. The ship is powered by a trio of nuclear reactors and propelled by a unique counter-rotating exposed turbine with variable pitch blades, allowing it to vector thrust for increased maneuverability.
Crewed by just under two hundred men, the Titleist was considered spacious when constructed, with crewmen given their own rather lavish quarters. Post Exchange
, the ship's crew was supplemented by family members and civilians alike, with cargo space being turned into makeshift bunks. The ship is capable of purifying it's own air and water, and algae and plankton filtered out of the water is used in onboard processing plants to make some foodstuffs. The crews main diet consists of seaweed, fish, crabs and provisions traded for at some of the surviving seaports.
The Titleist's captain, Daniel Rodgers, earned his nickname after the Exchange
when he used one of his nuclear tipped cruise missiles to wipe out an entire fleet of pirate ships that had been harassing the eastern Floridian coast. He was definitely an eccentric man, loving rum and fishing from the sail of his ship under the stars. He was known to come to the aid of coastal colonies and his ship was a welcome sight to many sailors who found themselves in distress on the open seas.
This model was made for the same post-apoc story as Groache's Flying wing:
