This photo is from a Raytheon magazine ad for their GPS-jam resistant guidance systems.

I received this letter upon request of anyone who knew what bomb this is:

Dear Tony:

The photo you have of the 2000 lb GBU is a very old photo. My father took that very picture for the US Air Force in 1971 for the Raytheon Corp. as an ad to sell the GBU seeking head to the Air Force and Navy during the Vietnam War. Precisely it is the LGB Unit GBU-10 E/B 2000 lb bomb.
