November11, 2006: Turkey has bought 17 American S-70B Seahawk helicopters. The S-70B is an export version of the U.S. Navy SH-60B Seahawk, which is in turn based on the U.S. Army UH-60 Blackhawk. This helicopter can stay in the air about two hours per sortie, carrying two tons of cargo, or a dozen or so people. The Seahawk is the most widely used naval helicopter in the world. Sikorsky Aircraft produces the Seahawk, and deliveries to Turkey won't begin until 2009.
