The American B-1B Lancer bomber flew over the Strait of Hormuz, the narrow mouth of the Persian Gulf through which 20% of all oil traded passes.
It also flew over the Red Sea, its narrow Bab el-Mandeb Strait and Egypt's Suez Canal.
Strait of Hormuz
The Strait of Hormuz is a strait between the Persian Gulf and the Gulf of Oman.
It provides the only sea passage from the Persian Gulf to the open ocean and is one of the world's most strategically important choke points.
On the north coast lies Iran, and on the south coast the United Arab Emirates and Musandam, an exclave of Oman.
A third of the world's liquefied natural gas and almost 25% of total global oil consumption passes through the strait, making it a highly important strategic location for international trade.
Bab-el-Mandeb
The Bab-el-Mandeb is a strait between Yemen on the Arabian Peninsula, and Djibouti and Eritrea in the Horn of Africa.
It connects the Red Sea to the Gulf of Aden.
The Bab el-Mandeb Strait is a chokepoint between the Horn of Africa and the Middle East, and it is a strategic link between the Mediterranean Sea and the Indian Ocean.
The island of Perim divides the strait into two channels, of which the eastern is known as the Bab Iskender (Alexander's Strait), while the western is known as Dact-el-Mayun.
Suez Canal
The Suez Canal is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez and dividing Africa and Asia.
The Canal provides the shortest maritime route between Europe and the lands lying around the Indian and western Pacific oceans.
The canal extends 193 km between Port Said in the north and Suez in the south.
The canal utilizes several lakes: from north to south, Lake Manzala, Lake Timsah , and the Bitter Lakes—Great Bitter Lake and Little Bitter Lake.
About 12% of world trade passes through the canal each year, everything from crude oil to grains to instant coffee.
It allows tankers and container ships to avoid a long trip around the southern tip of Africa.
