Monitor 33 is a First World War gunship, built to bombard coastal positions from the sea. She is one of the few such vessels surviving. One interesting aspect is her camouflage, which is not designed to render her ‘invisible’ but specifically to confuse the range finding systems of the day so that land and sea-based artillery would find it difficult to fix her and accurately direct directly there gunfire.
Monitor 33 is currently on display at the Portsmouth historic dockyard
