yes that's the Ski-jump, angled up by 15 degrees it allows the harrier to start it's take off roll from just before the start of the ramp and, from a standing start, without the need for a catapult, the harrier can take off in a very short distance without having to take off vertically which limits payload, when the harrier wants to land he'll fly up along side the ship, come to starboard until she's over the deck, and hover down vertically for a much safer landing than the conventional hook and runway method..........
