Yes. But there important differences.
Grand Slam and Tallboy were very heavy, armour piercing headef, gravity nombs. Unguided but spin stabilized by their tailfins.
MOAB ‘llike the Daisy Cutter is a pallet loaded, parachute stabilized, fuel air aerosol surface nomb. Very, very big surface bomb.
There is rocket propelled earth piercer with terminal guidance for subsurface targets.
Terrible editing there Cook.

Neither the GBU-43/B (MOAB) nor the BLU-82B (”Daisy Cutter”) use fuel-air explosive. GBU-43/B is filled with H-6: a mix of RDX, TNT, powdered aluminum, paraffin wax, and calcium chloride. BLU-82B was filled with GSX, a variant of ammonal: a mix of ammonium nitrate, powdered aluminum, and polystyrene.
Fuel-air munitions of such size are subject to engineering limitations and development in this area was discontinued, because results weren’t predictable enough.
The filler mistake keeps cropping up. This time, we can blame the website posting the initial article.
