Machine Information
Designer(s) Professor Calculus
Builder(s) Professor Calculus

Purpose To find Red Rackham's Treasure

Professor Calculus' Submarine was a Submarine built by Professor Calculus to search underwater for Red Rackham's Treasure. It originally could hold more than one person but after it split in half Professor Calculus built it again, much smaller this time.

At first Tintin and Captain Haddock refused to use the submarine in the treasure hunt but after Professor Calculus sneaked on board their ship, they had no choice but to use it. In the end it turned out to be very useful.

After Red Rackham's Treasure it hasn't been seen since.
