WB-57F- Weather reconnaissance version.
- RB-57Fs used for high altitude atmospheric sampling in support of nuclear weapon testing and weather research. Two WB-57F aircraft were transferred to NASA and are the only WB-57s still flying in the world today [4]. They are used for atmospheric research and for monitoring Space Shuttle takeoff and landing.
