It's a big 'un for sure and for certain.
Where did you get this photo and the source that it is one of the 30,000 20.5 feet long MOP as it certainly does not look to be either 20.5 feet long nor large enough to be 30,000 pounds...
Here is a 21,600-pound MOAB... and it is bigger (It is 30 feet long with a diameter of 40.5 inches) than the one you have pictured.
