UBI Soft just tossed up the official Harpoon 4 website. The site includes a dozen never-before-seen images from Harpoon 4, wallpapers, detailed descriptions of your favorite submarines / jets / ships, FAQ and much more.. The current development is back on track for a March 2003 release. Here is a small game description:

The world's naval powers are now at your command! If it floated, flew, or submerged between 1984-2000, it's probably in Larry Bond's Harpoon 4. This is the ultimate simulation of modern naval warfare. Featuring over 1,000 ships, subs, aircraft, and ground formations, this real-time naval strategy game is epic in scope and detail. Maneuver your forces on a highly detailed and customizable map of Northern Europe. Plan and execute detailed attacks on multiple enemy units and watch the battle unfold before your eyes.
