How it Compares
The AW139 National Security Helicopter® is in use in the United States and around the world in multiple roles: Law Enforcement, Rescue, Air Medical, Fire Fighting, Border Protection, and Military Response, Airlift, Gunnery. These varied “government operator” missions are conducted safely, effectively and economically. The AW139 National Security Helicopter® is the right choice because both performance and cost matter to the tax-payer.

Developed to exceed rigorous FAA FAR Part 29 standards, the AW139 is particularly well-suited for security and personnel transport missions. The AW139 flies 50% faster, carries 5000 lbs. more and has a 30% larger cabin than the UH-1N yet fits in the same footprint. Additionally, both our cost per flying hour and maintenance man hour per flight hour are also lower. Safer. Better. Costs Less.
