In the dead of night, the two CH-46 Sea Knights lift off from the deck of the USS Ronald Reagan and headed toward Iraq. On board are elite members of the U.S. Marine Corps Raiders, who are tasked with conducting a critical mission deep in enemy territory. As the helicopters fly over the rugged terrain, the night swallows all light so the crew press on using night vision goggles. The Marines remain silent, mentally preparing themselves for what lay ahead.
Slipping quietly through the night sky, the CH-46 Sea Knights begin their descent between the high mountain peaks surrounding the quiet valley below. Touching down on an open field, the special forces troops rapidly exit the helicopters and secure the area, setting up a perimeter to protect the Sea Knights as they rise up from the landing zone. The troops then begin their mission, moving swiftly and silently through the rugged terrain, relying on their training and expertise to achieve their objectives.
Approximately five miles from the landing zone, the unit quietly enters a small village, identifies and captures a high-value target, and swiftly moves back to a different rendezvous point with the helicopters about 1 mile away. As the mission draws to a close, the CH-46 Sea Knights break the silence of the night, energizing the air surrounding this new landing zone and extracting the team and their new guest. They lift off into the night sky as they head back to the safety of the carrier. The successful air assault had been a critical operation in the ongoing fight against terrorism, demonstrating the bravery and skill of the U.S. military in the face of danger.
The CH-46 Sea Knight is a multi-personnel rotary-wing aircraft, capable of being flown and maintained by up to 5 crew members – 2 pilots, 1 crew chief, plus an aerial gunner/observer and a tail gunner. However, it can be adapted for a 3-person operation depending on the mission at hand.
