Seems as though the concensus is that it's a munition that's also considered a "missile". "Today's operation again proved the viability and capability of the Harpoon Block II through a modernization upgrade of the missile using proven hardware components from the SLAM-ER and JDAM missile programs," said Capt. Carl Reiber, Navy program manager, Standoff Missile Systems (PMA-258)boeing.com Joint Direct Attack Munition (JDAM) missile is used extensively in current U.S. war effort, technology that wasn't available in Gulf War. JDAM is attached to missile's tail and converts it from ordinary "dumb" gravity bomb to GPS-guided smart bomb. JDAM kits cost $20,000 each, half of price of laser guided kits and tenth of cost of Joint Standoff Weapons (JSOWs), Global Security spokesman said. Organization said it took only 30 min. to convert "dumb" bomb into smart bomb. JDAM can be released up to 15 miles from target. Its Inertial Guidance System (INS) with GPS updates allow control fins to correct trajectory right up until impact. Accuracy is nearly as good as laser-guided bombs, but isn't degraded by bad weather. JDAM was upgrade on existing inventory of Mk-83 1,000- and Mk-84 2,000-pound general purpose unitary bombs and 2,000-pound hard target penetrator bomb by integrating guidance kit consisting of Inertial Navigation System (INS) and Global Positioning System guidance kit. Version for 1,000-pound JDAM is designated GBU-31, and 2,000-pound version is GBU-32. JDAM variants for Mk-80 250-pound and Mk-81 500-pound bombs are designated GBU-29 and GBU-30, respectively. globalsecurity.org
