Sadly, I couldn't find any information of this thing. NASA only had photos, and when I looked it up only "Martin B-57 Canberra" came up, and this is not a Camberra. Maybe it's a version, but I want information of the WB-57F, not the B-57. Well, here's some information about the B-57 from Wikipedia:

The Martin B-57 Canberra is an American-built, twin jet engine tactical bomber and reconnaissance aircraft that entered service with the United States Air Force (USAF) in 1953. The B-57 was a license-built version of the British English Electric Canberra; the Glenn L. Martin Company later modified the design to produce several different variants.
