Boeing CH-46D/E Sea Knight

posted by Jiri Wagner

The CH-46D Sea Knight is a medium lift assault helicopter, primarily used to move cargo and troops.

The CH-46D Sea Knight helicopter is used by the Navy for shipboard delivery of cargo and personne. The CH-46E is used by the Marine Corps to provide all-weather, day-or-night assault transport of combat troops, supplies and equipment. Troop assault is the primary function and the movement of supplies and equipment is secondary. Additional tasks may be assigned, such as combat support, search and rescue, support for forward refueling and rearming points, aeromedic evacuation of casualties from the field and recovery of aircraft and personnel.

The CH-46 Sea Knight was first procured in 1964 to meet the medium-lift requirements of the Marine Corps in all combat and peacetime environments since that time. The Sea Knight fleet is currently being maintained until a suitable replacement is approved.
