Columbia Helicopters, the world’s leading heavy-lift helicopter OEM, MRO and operator, announced in March 2023 that it is providing the Korean Forest Service with a brand-new Model 234 multi-mission Chinook. The aircraft will be used primarily for firefighting during the day and at night using NVGs
Columbia Helicopters Chinook 234 can take on nearly 11,000 lit of water and drop it in four seconds
The Chinook 234 tandem rotor system does not require a tail rotor for stability
