Mr. Damien Cuello uses a crane and good eye sight to positions the cylinder head he rebuilt over the 6 studs that will hold it to the 10 1/4 inch diameter, 9 1/2 inch deep cylinder of the V-12 Mitsubishi S12U turbocharged diesel engine in the power production facility of the 45th Operations Group, Detachment 2, at Ascension Auxiliary Airfield (AAF), South Atlantic Ocean on June 27, 2009. The engine drives a 1900kW generator that supplies power to the electrical grid for the airfield, Space Command sites and facilities, and a royal air force airfield facility on the island. Mr. Cuello is a Computer Sciences Raytheon contract associate in charge of maintenance for 6 wind turbines and 5 diesel generators. Wind turbines were designed to work in parallel with the diesel generators to form a hybrid power production solution. The wind turbines lower the load on the engines, extending their life cycle. Ascension AAF's award winning economical self-sufficiency solutions also includes drinking water production and waste water treatment. The mission of Det. 2 is support of eastern range space launches by collecting and disseminating radar, telemetry and tracking data. Ascension island is 35 square miles in a remote location midway between Brazil and Angola. The nearest country is Liberia - 1000 miles away. (U.S. Air Force photo/Lance Cheung)
