Which types of aircraft are primarily associated with the Heavy Helicopter Company?

The Heavy Helicopter Company is primarily associated with the CH-47 Chinook, which is a tandem rotor heavy-lift helicopter. The CH-47 is specifically designed for transporting troops, cargo, and equipment in a wide range of operations, including troop movement, supply missions, and medical evacuations. This helicopter's size, capacity, and versatility make it an ideal fit for missions requiring the transport of heavy loads and support to ground forces.

In contrast, the UH-60 Black Hawk is primarily a utility helicopter used for troop transport and logistical support, while the AH-64 Apache is designed for attack missions with its advanced weaponry and systems. The OH-58 Kiowa, on the other hand, is an observation helicopter focused on reconnaissance and surveillance missions. None of these aircraft fulfill the specific heavy lift roles that the CH-47 excels in, which is why the CH-47 is the correct answer when discussing the Heavy Helicopter Company.
