Yes, a 'body of water'. The well deck is flooded by ballasting down the ship, both fore and aft. All ocean going ships use ballast tanks to maintain trim and they either have empty spaces they flood or they shift fuel around to different tanks, but Amphibs have specific spaces they flood. The upper and lower rear ramps are opened, and ballast (sea water) is added to drop the ship down in the water..usually just enough so the larger craft can exit. The below picture shows an LCU that had already been launched while the ship was ballasted down farther than in the picture to provide enough draft for it to get out. It then pulls up to the ramp and the cargo is either driven on or in the case of palletized loads, brought on via forklift. Air cushion LCACs can exit dry deck tho they usually do not. This ship's sole purpose is to transport and land Amphibious troops and their equipment..ie, US Marines. The MEU sometimes works with 2 other amphib ships, (LSD, LSH, and LSA)s and It can carry nearly a full Marine Expeditionary Unit (MEU) and everything they need to fight for 15 days, anywhere in the world. There is always at least 1 MEU afloat, and usually 2..one in each major area of contention or conflict, but the 3 ship group makes up what is called and Expeditionary Strike Group (ESG) . It carries enough supplies and troops to fight 30 days. There are 9 ESGs and each is usally backed up just over the horizon by one of 10 USN Carrier.

 A little bit older ship (USS Iwo Jima) and the layout is similar but not as big or modern as the current class LHD

I spent over a year on LCUs, LCM8s, and other 'gator' craft so I'm pretty familiar with them. The newer vessels and vehicles came after I got out of the military.
No one other than bar owners and brothels wants to wake up one morning and find an Expeditionary Strike Group parked just offshore, especially since there's a pretty good chance that just over the horizon there's one or more of these loitering about.

All great info about the LHDs except a minor quibble on the LCAC part. Was in the program for 21 years and flew them for 10. Unless the craft is disabled, we enter and exit the welldeck as close to a dry well as possible. Usually the ship is at a 'shallow wedge' configuration so the stern ramp is submerged with only about 6" of water over it and nothing forward of the aftmost LCAC spot. This allows us to easily enter, not spray water everywhere into the ship because of the props and thrusters, and still be protected from grounding in case of a rogue wave on entrance/departure.

Thanks for that correction!! LCACs were just a dream when I was still in and I was relying on that kind of information posted on a military site (TWS) this week. Always good to hear from you..I knew someone here had served on them but couldn't remember who it was.
You have any pictures of the upper and lower vehicle storage areas when they were loaded?

The fire is reportedly extinguished now.

I heard that, this morning. Thanks for all of the info. Your perspective is quite interesting.

I probably do somewhere but I would have to dig up a cruise book to find them.
I can't remember exactly what they were capable of holding in the ship in terms of vehicles since the loadout was dependent on the Marines projected mission but basically if there is a clear space on a ship, the Corps will find something they need to fit there We always had preloads on the deck of the LCAC when deployed since we aren't going to let that flat space go to waste.
We would have 3 LCAC deployed inside the LHD and onload/offload of a ship would take between 20 and 30 runs. A typical LCAC loadout might be 10 uparmored HMMWVs or 2 7-ton truck pulling howitzers or even an M1A1 tank with mineplow.
Most likely since they were in the yard, the welldeck was completely empty of Marine vehicles. They generally aren't loaded for any length of time until the beginning of deployment when we roll down from Norfolk to Camp Lejeune to pick them up. Before that we only had them on board for a week or two at a time when doing predeployment exercises.
My guess is the contractors had that area slam full of repair parts, metal, paint, welders/welding gas bottles, removed parts/equipment, you name it. It becomes a sheltered secure place to store things until needed in the repair cycle. Fighting a fire in that area would be trying to drag a firehose through a junkyard. I feel for those guys and am glad nobody seems to have been seriously injured[This message has been edited by AlanD (edited 07-17-2020).]

Judging by the photo showing the four holes in the deck, I'd say that ship is going to out of commission for a few years. - if they decide to do repairs.
Cost of replacement was estimated about $4 billion (2020 dollars)
Ship when built was estimated to be about $750 million (1997 dollars)

The replacement, should the Bonhomme Richard not be economically feasible to repair, would probably come one of the newer versions of her class, like Makin Island which was laid down in 2004 and commissioned in 2009. Both Wasp Class but with huge differences. Makin Island has hybrid diesel/gas turbine drive propulsion and many other more modern features that BHR did not have originally. Some in the USN and even in the MAGTF question whether the traditional type of amphibious warfare is even possible nowadays.
