The first two UH-46D helicopters for the U.S. Navy are shown prior to delivery in 1966, lifting off from the Boeing Company's Flight Center near Philadelphia enroute to Ream Field, California. The two UH-46s could transfer up to 100 tons of cargo per hour between ships, using the Navy's "Vertical Replenishment" technique. The UH-46D featured General Electric T58-10 engines, cambered rotor blades, and a new control system which resulted in improved pilot visibility over the instrument console.

The U.S. Marine Corps retired the CH-46 Sea Knight in August 2015.
