I don't want to sound glib here... but I'm wondering which method of
delivery they're planning for a 1.4M+ pound weapon.

700 ton is the equivalent amount of TNT needed to produce the same size
blast.  I'm sure the device, using more efficient explosives, weighs far
less.

Nope, it's the other way around: the ANFO charge weighs 700 tons and
has a yield equivalent to a touch less than 600 tons of TNT.

"The June test will detonate 700 tons of heavy ammonium nitrate-fuel
oil emulsion -- creating a blast equivalent to 593 tons of TNT -- in a
36-foot-deep hole near a tunnel in the center of the Nevada Test Site,
according to official reports. It aims to allow scientists to model the
type of ground shock that will be created, and to weigh the
effectiveness of such a weapon against its collateral impact."
