Correct, they don't move independently of one another, as there's a central drive motor along the center of the fuselage occupying the space between the rear deck machinery and the fuel tanks in the belly. However all four foils are present. Both upper foils are clearly visible in the image. The lower-port foil is, as well. For the lower-starboard if you look very closely just below where the nose cone meets the fuselage you can see the tip laser cannon. It's kind of lost against the surface of the water, but it's that thin light-colored line that looks like it's sticking out from the netting along the side.
