Explosive yield varied from 70 kilotons of TNT to 1 megaton of TNT. Its payload is a single 1 Megaton warhead. It is unknown if Israel's reported thermonuclear weapons are in the megaton range. This was revised in November 1955, with "megaton" replacing "thermonuclear". The bunker is built to deflect a 30 megaton nuclear explosion as close as . It is estimated that each megaton of yield produces about 5000 tons of nitrogen oxides. Its yield made it technically a megaton weapon. The "megaton (of TNT)" is a unit of energy equal to 4.184 petajoules (). Teak would be the first high-altitude test to have a payload in the megaton range. Only one was an air burst, the 3.8 megaton Redwing "Cherokee" test. In November 2010, Fox announced that EuropaCorp would produce a sequel directed by Olivier Megaton. The RDS-37 was successfully tested on 22 November 1955 with a yield of 1.6 megaton. Budiansky has said in interviews that it is a portmanteau of "electronic" and "megaton". The other carries two 20 megaton devices. The RNEP was to use the 1.2 megaton B83 physics package.
