Even as an old Army helicopter pilot that caught my eye too. Now, if I just knew what AGF-3 and LPD-3 meant.
You Navy guys and your funny names for things.
AGF = Auxiliary, General, Flagship = (We ain't telling you what the ship does, but it carries a Flag Officer (?)
LDP = Landing Personnel Dock = Carries Marines and landing craft. The Well Deck is partially flooded, the stern gate is opened, and the landing craft go out and go in to dock.
