(19,362 posts)The widely-used Lockheed Martin GBU-28 5,000 lb. 'bunker-buster' bomb with a BLU-109 penetrator head carried only by the Air Force's F-15E's and B-2s, contains 1.5 metric tons of depleted uranium, compared to only five kilograms in the 120 mm shell. According to the GBU-28 Bunker Buster animation on USA Today the warhead is "classified".6 The 30 mm PGU-14 armor-piercing cannon shell contains 4,650 grains [0.66 pounds ] of extruded DU, alloyed with 0.75 weight percent titanium.7 The Olin Corporation is the sole maker in the U.S. of DU antitank rounds, and its foundation funds "research" which purports to show that DU has no harmful health effects.
An "improved" version of this bomb - the GBU-37B, made by Northrop Grumman - with a BLU-113 warhead also contains DU. Another bunker-penetrating munition dropped on caves and tunnels in Afghanistan is the AGM-130 - widely used in the Tora Bora campaign - which is a 2,900 pound, rocket-propelled bomb fired by helicopters and F-15E's up to 40 miles away from its target.8 Other earlier versions of bunker-penetrating bombs include the GBU-15, GBU-24, GBU-27 and GBU-31.
