The Iwo Jima was an LPH (LPH-2, to be exact); the LPHs didn’t have well decks. (The LPHs had also been decommissioned back in the 90s.)
Thanks for letting me know.
You are correct about the former USS Iwo Jima (LPH-2), a ship that I knew very well decades ago. But you might not realize a new Wasp-class USS Iwo Jima (LHD-7) was commissioned in 2001. She's the seventh of eight Wasp-class Landing Helicopter Dock amphibious warfare vessels that are essentially small aircraft carriers with flooding well decks for amphibious landing craft in addition to helicopters and F-35 jets.
One of my best friends from grades 1-12 served on the Iwo Jima in the Pacific, while I was on the FDR (CVA-42) in the Med.
