The Egyptian Navy (El-Quwwāt el-Bahareya el-Miṣriyya), also known as the Egyptian Naval Force, is the maritime branch of the Egyptian Armed Forces. It is the largest navy in the Middle East as well as Africa, and is the twelfth largest (by the number of vessels) navy in the world. The navy protects more than 2,000 kilometers of coastline of the Mediterranean Sea and the Red Sea, defense of approaches to the Suez Canal, and it also supports for army operations. The majority of the modern Egyptian Navy was created with the help of the Soviet Union in the 1960s. The navy received ships in the 1980s from China and Western sources. In 1989, the Egyptian Navy had 18,000 personnel as well as 2,000 personnel in the Coast Guard. The navy received ships from the US in 1990. US shipbuilder Swiftships has built around 30 boats for the Egyptian Navy including mine hunters, survey vessels, and both steel and aluminium patrol boats. Egypt has had a navy since Ancient Egyptian times. The Ancient Egyptian Navy was a vital part of the military of ancient Egypt. It helped to transport troops along the Nile River and fighting many battles such as the Battle of the Delta against the Sea Peoples, and played a major role in Egyptian Wars and battles such as the siege of Avaris in c. 1540 BC. The Ancient Egyptian Navy imported many of their ships from countries such as the Kingdom of Cyprus. Several Ancient Egyptian royal ships are still present today. In the early 1800s, Egypt under Muhammad Ali Pasha developed a modern European-style army and navy. After intervening in the Greek War of Independence at Ottoman Turkey's request, the Egyptian navy was destroyed in 1827 at the Battle of Navarino by the fleets of Great Britain, France and Russia. With the Egyptian army in Greece then isolated, Muhammad Ali made terms with the British and withdrew a year later. A replacement fleet was built for the First Egyptian–Ottoman War in 1831, and landed troops at Jaffa in support of the main Egyptian army marching into Syria.
