Harpoon3.6 1937 – 1949 (WW2) Database & Scenarios

IMPORTANT NOTE: All further work on the commercial versions of computer Harpoon was suspended in mid-2013 after more than two decades. The guys behind HarpoonHQ (now WarfareSims) saw the signs of Computer Harpoon’s collapse as early as 2006 and started developing our own simulator named Command: Modern Air/Naval Operations which was released in September 2013. Since the owners of WarfareSims have been avid Harpoon fans since the late 1980s / early 1990s, we decided (on popular demand) to keep some of the Harpoon material on our new site even though we’ve now scratch-built our own product that is not related with the Harpoon franchise. The material is provided as-is and is no longer supported. WarfareSims’ time and energy is now devoted to continued development & enhancement of Command: Modern Air/Naval Operations which has similar focus as Harpoon but with a much more pronounced balance between air and naval operations.
