Boeing CH-47F Chinook Block II

The Chinook is a tandem-rotor heavy-lift helicopter — two rotors in tandem (front and rear) eliminate the need for a tail rotor and provide extra lift capacity. Two Honeywell T55-GA-714A engines, max payload 12,700 kg, 33–55 troops, external load via three cargo hooks (for amphibious vehicles, M777 howitzers). Block II adds ACH (Advanced Composite Helicopter rotor blades), reinforced fuselage, improved FADEC engines, and the T55-GA-714AB engine. Unit price: ~USD 38 million. Widely fielded (US, UK, NL, DE, IT, ES, AU, CA, JP, ROK, India, etc.).
