Expeditionary Transfer Dock

An expeditionary transfer dock (ETD) is like a really big boat that can hold a lot of other boats and vehicles. It's kind of like a big floating garage or parking lot.

Some of the boats and vehicles that can be stored on an ETD include small boats, trucks, tanks, helicopters, and airplanes. An ETD can actually hold up to three helicopters and eight landing craft or other smaller boats.

An ETD is especially useful for the military because it can carry lots of equipment and supplies across long distances to different places all around the world. It's like a mobile base that can be moved wherever it's needed.

When the ETD arrives at a new location, it can open up like a big mouth to let all of the boats and vehicles out. This allows the military to quickly and easily transport all of their equipment to wherever it's needed for their mission.

Overall, the expeditionary transfer dock is a big, versatile boat that can travel long distances and hold lots of equipment and vehicles for the military.
