US Navy Submarine Seen At Diego Garcia, Indian Ocean
Flag Diego Garcia, a small atoll in the Indian Ocean, often plays a geostrategic role. Its central location, combined with relative isolation, make it an ideal base. Although a British territory, it is used by both the U.S. Navy and Air Force. The base is already important today, and could become even more important if China expands its naval activities in the Indian Ocean. China already has a naval base in Djibouti on the Horn of Africa, and may build a base in Gwadar, Pakistan.

So the base's relevance was recently demonstrated when a US Navy submarine made a discrete port call there.


The USS Georgia (SSGN 729), an Ohio Class cruise missile submarine (SSGN), visited from September 25 to at least September 29. The submarine conducted a crew swap. Although the visit has since been publicized by the US Navy, the submarine was visible on commercial satellite imagery at the time.

The island is part of the Indian Ocean's Chagos Archipelago. It is over 1,100 miles (975 nm / 1,800 km) south of the tip of India. Yet it is close enough to potential hotspots to be a useful staging post for forward operations. This makes it critical important for the US, allowing it to project power in the Middle East and Africa as well as Indian Ocean, and maybe even South China Sea.
