I wonder whether it's as big as the USAF's new MOAB.

Really big FAE devices raise the question of what they're really good for. Are they really more useful or effective than, for example, dumping the device's weight in cheap conventional iron bombs on the target?

I believe US military doctrine holds that big FAE devices, and similar things like the "Daisy Cutter" are best used for rapid minefield clearance, though I have also heard rumors that they dropped a large number of them on Taliban positions in Afghanistan in 2001-02 also.
