The B61 has been under development and carried under different variants for quite a bit longer than any one leader can be considered for..and deployment of this version is out to 2023 and beyond for some aircraft. So... - See more at: www.abovetopsecret.com...
Carried by U.S. and NATO nuclear-capable bombers and fighter jets, the B61-12 is an upgraded version of the B61, which was designed in 1963.

The B61-12 version has four selectable yields — 0.3, 5, 10 and 50 kilotons — according to the Federation of American Scientists.

Several hundred millions more are required to integrate the B61-12 on five different aircraft, including Belgian, Dutch, German, Italian and Turkish fighter-bombers. An estimated 480 B61-12 bombs are planned, with first production unit in 2020.
Now wait just a cotton pickin' minute, are we selling these to Turkey?!
