The drones and other military aircraft have crowded the skies over the Horn of Africa so much that the risk of an aviation disaster has soared.
Since January 2011, Air Force records show, five Predators armed with Hellfire missiles crashed after taking off from Lemonnier, including one drone that plummeted to the ground in a residential area of Djibouti City. No injuries were reported but four of the drones were destroyed.
Predator drones in particular are more prone to mishaps than manned aircraft, Air Force statistics show. But the accidents rarely draw public attention because there are no pilots or passengers.
As the pace of drone operations has intensified in Djibouti, Air Force mechanics have reported mysterious incidents in which the airborne robots went haywire.
In March 2011, a Predator parked at the camp started its engine without any human direction, even though the ignition had been turned off and the fuel lines closed. Technicians concluded that a software bug had infected the “brains” of the drone, but never pinpointed the problem.
“After that whole starting-itself incident, we were fairly wary of the aircraft and watched it pretty closely,” an unnamed Air Force squadron commander testified to an investigative board, according to a transcript. “Right now, I still think the software is not good.”
Djibouti is an impoverished former French colony with fewer than 1 million people, scarce natural resources and miserably hot weather.
But as far as the U.S. military is concerned, the country's strategic value is unparalleled. Sandwiched between East Africa and the Arabian Peninsula, Camp Lemonnier enables U.S. aircraft to reach hot spots such as Yemen or Somalia in minutes. Djibouti’s port also offers easy access to the Indian Ocean and the Red Sea.
“This is not an outpost in the middle of nowhere that is of marginal interest,” said Amanda J. Dory, the Pentagon’s deputy assistant secretary for Africa. “This is a very important location in terms of U.S. interests, in terms of freedom of navigation, when it comes to power projection.”
The U.S. military pays $38 million a year to lease Camp Lemonnier from the Djiboutian government. The base rolls across flat, sandy terrain on the edge of Djibouti City, a somnolent capital with eerily empty streets. During the day, many people stay indoors to avoid the heat and to chew khat, a mildly intoxicating plant that is popular in the region.
Hemmed in by the sea and residential areas, Camp Lemonnier’s primary shortcoming is that it has no space to expand. It is forced to share a single runway with Djibouti’s only international airport, as well as an adjoining French military base and the tiny Djiboutian armed forces.
