Red Sea
Red Sea: strategic northern tropical sea and vital shipping corridor facing maritime security threats
The Red Sea is the world’s northernmost tropical sea, about 2,250 km long, roughly 438,000 km2 in area and up to 2,730 m deep. It has long been a trade artery, used by ancient Egyptians, improved under Darius the Great, favoured for Roman trade with India from Augustus, and central to the medieval spice routes. Historic raids, such as Raynald of Châtillon’s 1183 expedition, also feature in its past.
Since October 2023 the Red Sea has been a flashpoint for maritime security. Houthi forces have attacked and hijacked commercial and military vessels, declared bans on Israeli shipping (including a 4 February 2024 ban), and are reported to have struck dozens to hundreds of ships during a prolonged campaign. A US-led Operation Prosperity Guardian began in December 2023 to protect shipping. States in the Gulf have taken varied stances, and satellite VIIRS records showed recent thermal detections in the Red Sea area on 12 June 2026.
- Physical profile: ~2,250 km long, ~438,000 km2 area, max depth 2,730 m, northernmost tropical sea
- Ancient and medieval role: Egyptian exploration circa 2500 BCE, Darius-era canal and navigation work, Roman and spice trade routes
