DID - April 28/06: A $52.4 million ceiling-priced modification to a previously awarded cost-plus-award-fee contract (N00019-02-C-3002). It exercises an option to certify the GBU-39 Small Diameter Bomb for the U. S. Air Force Joint Strike Fighter conventional take off and landing (CTOL) aircraft,
and also eliminates the effort to certify the F-35A for wind corrected munitions dispenser (WCMD) GPS-guided cluster bombs, and for
external fuel tanks.
