Jan. 27 (Bloomberg) -- One of the versions of Northrop Grumman Corp.’s Global Hawk surveillance drone is not as capable as Lockheed Martin Corp.’s manned U-2 spy plane, Air Force Chief of Staff Norton Schwartz said in a Pentagon press briefing today.
Defense Secretary Leon Panetta yesterday proposed canceling purchases of 10 so-called Block 30 Global Hawk models and said the Pentagon would continue buying the more advanced Block-40 model.
Schwartz declined to specify how many Block-40 planes the Pentagon would buy in the next five years.
