Project Habakkuk's scale created its own engineering problems

What were the main practical problems with Project Habakkuk's pykrete carrier?

Its scale made steering, command, replenishment, and flight-deck rigidity difficult even though the vast carrier promised exceptional capacity and resilience.

Project Habakkuk is an attractive super-carrier idea whose extreme size changes every practical calculation. Steering and commanding it would be difficult, while replenishment at sea might resemble smaller ships docking alongside the carrier. Its mass could absorb punishment and sustain air attacks, though the Bismarck comparison is a playful illustration rather than a firing-trial estimate. A structure built on such a mass of ice might also develop an uneven flight deck. The immense deck could tolerate roughness like a large land airfield, but scale would not eliminate the engineering and handling problems.
