Robin (nuclear primary)

The Robin was the common design nuclear fission bomb core for several Cold War designs for American nuclear and thermonuclear weapons, according to researcher Chuck Hansen.[1] [2]

Primary is the technical term for the fission bomb component of a thermonuclear or fusion bomb, which is used to start the reactions going and implode and detonate the second, fusion stage.

The Robin design was used as the W45 nuclear warhead, and as the primary in the W38 and W47 thermonuclear weapons. [3]

It has been associated with the W48 nuclear warhead, but this is probably an error.

History

The Robin is apparently a weaponized version of the Swan primary tested during Operation Redwing and shares its design features.

gollark: I have no idea how they actually work.
gollark: Yes, I looked into that, but the optics seems fiddly.
gollark: Maybe it just doesn't have the data and is trying to guess.
gollark: It's very annoying that Google Glass-type things are basically not available for consumer use because any company making them keeps cancelling such products, getting acquired, or collapsing.
gollark: Anyway, the adblocker thing should actually be practical with current tech, although I'm not sure about the status of the opaqueable glasses or whatever you'd need.
