How long does it take to build a large floating dry dock?
Short answerA recent large example took about six years from order to christening, and a new British design study could add risk before construction starts.
NotesA domestic floating-dock project would first need design work unless Britain accepted an off-the-shelf design. The large Atlas dock built by Bollinger for General Dynamics provides a recent comparison. Atlas was ordered in 2019 and christened in 2025, giving a roughly six-year interval. Maintenance infrastructure therefore has to be ordered before a fleet availability crisis becomes acute.
