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:
“Here is a pen and here is a pencil,
Here’s a typewriter, here’s a stencil,
Here is a list of today’s appointments,
And all the flies in all the ointments,
The daily woes that a man endures—
Take them, George, they’re yours!”
—Ogden Nash (1902–1971)
