A submarine pen (U-Boot-Bunker in German) is a bunker which is designed to protect submarines from air attack. The term is generally applied to submarine bases constructed during World War II, particularly in Germany and the occupied countries which were also known as U-boat pens (after the phrase "U-boat" to refer to German submarines).
Famous quotes containing the word pen:
“Then my verse I dishonour, my pictures despise,
My person degrade & my temper chastise;
And the pen is my terror, the pencil my shame;
And my talents I bury, and dead is my fame.”
—William Blake (1757–1827)
