Ask anyone to picture a military helicopter, and chances are high they will visualize the Bell Helicopter Textron UH-1. That’s because it is the most successful military helicopter ever produced. It is the epitome of mission effectiveness, reliability and safety. Over 16,000 UH-1s have been produced, and have operated in challenging environments ranging from the rugged mountains of Bosnia, to the frozen vastness of Antarctica. Many of the first UH-1s delivered are still flying today, some airframes having logged over 30,000 hours. Militaries around the world continue to depend on this proven workhorse to execute combat assaults, evacuate wounded soldiers, transport senior staff, or complete any other helicopter mission you can imagine.
