The Pentagon’s latest Selected Acquisition Report shows a schedule slip for the Air Force’s B-2 bomber radar modernization program. This comes as no surprise since service officials reported earlier to Congress about the B-2 getting kicked out of its spectrum. USAF tried to speed up its radar modernization program because the new equipment would incorporate the frequency change, but the new antenna requires more technical maturity, as noted by the House Appropriations Committee in its markup of the 2008 defense spending bill. The slip in this program could be six months or more.
Denys Overholser, the Lockheed Martin engineer whose insights on the mathematics of radar cross section led directly to the first operational stealth attack airplane and permanently reshaped combat aircraft design and tactics, died April 28 at the age of 86.
