the OP has LPH-2 in the title, so I didn't look for an LHD
the ships of the LPH Iwo class are the ships with the rounded flight deck on the front edge, they were smaller than the Essex class LPHs, but larger than the LPH Thetis Bay (former Escort Carrier)
the Iwo class ships are the ones that participated in the space capsule recoverys, any time it wasn't an Essex class at the pickup point, it was an Iwo class
