40th Helicopter Squadron

Quote:

The 40 HS currently employs the UH-1N "Iroquois" helicopter, commonly know as "Huey," a name that stems from its original designation of utility. The aircraft can carry up to 13 passengers at a maximum gross weight of 10,500 pounds. It has a range of 300 miles and can travel at a maximum airspeed of 130 knots (approximately 145 miles per hour). To date the unit has saved more than 425 lives and since 1973 has logged over 145,000 flying hours. The men and women of the 40th Helicopter Squadron are proud of their military heritage and continue to strive for excellence and better service for the 341st Missile Wing.
