The "physics package" of a Minuteman III/Mk-12 is about 250 pounds once
you take it out of the reentry vehicle, and has a yield of 170 kilotons
or so.

It's small enough to fit into one of my suitcases, and weighs less than
some things I've shipped airfreight during road shows. For example, it
weighs about half that of a professional video projector in a road case,
and is about three times the bulk.

The W-44 ASW warhead was about 170 pounds, and was certainly small
enough to fit into a suitcase or trunk (less than 1 foot diameter), with
a yield of 10 kilotons or so.

The W-25 warhead for the Genie AAM was about 220 pounds, and gave a
yield of about 1.7 kilotons.

Any of these could be considered a "suitcase" nuke, but not a
"briefcase" one.

But you also have to consider that the actual "pit" is very small
(grapefruit or thermos sized, according to the design), with explosives
wrapped around it (not that much, actually) and triggered with some
high-precision electronics. The problem in the past was that the
electronics and power supply were a major weight addition to the weapon,
and that we've had a half-century of electronics advance to make that
part pretty small.

The whole apparatus would have to be no larger than a couple of
footballs (or a basketball plus a laptop computer), and less than 50
pounds, for a yield of a kiloton or so.

And a thousand tons of explosives, plus radiation effects? Pretty hard
to ignore.

It is a "definitional" thing :-) I am aware of the devices that you mention. I also
know that none of them are the sort of thing you would casually walk into a
hotel with. Nor would sending the device "air freight" be such a bright idea.
