In the 1980s, the Somali federal government recruited the U.S. Navy, its new Cold War partner, to further enlarge the Mogadishu airport. The project included the construction of a modern control tower equipped with state-of-the-art navigational technology. The Somali Civil Aviation Authority (SOMCAA), which then regulated the national aviation industry, also signed a contract with the Italian firm Selenia worth an estimated 17 billion Italian lire ($2.5 million). The agreement stipulated that the company would build a second terminal for international routes as well as a new control tower. The Italian firm was also tasked with supplying air traffic control equipment.
