The GIUK gap (sometimes written G-I-UK) is an area in the northern Atlantic Ocean that forms a naval choke point. Its name is an acronym for Greenland, Iceland, and the United Kingdom, the gap being the two stretches of open ocean among these three landmasses. It separates the Norwegian Sea and the North Sea from the open Atlantic Ocean. The term is typically used in relation to military topics. The area has for some nations been considered strategically important since the beginning of the 20th century.^[1]
