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:
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.
