Now that's a BOMB !

The heavy GBU-57 is a 20-foot long GPS-guided bomb believed to be able to penetrate 200 feet of concrete before exploding,

At least they haven't drawn a cartoon picture of the prophet muhammed on it.

Yet.

They will, they will. unfortunately

Both Tallboy and Gram Slam looked far more bomb like than a waste bin with fins on. This is not a great step beyond 1944.

And you know this how?

Are you privy to the details of the weapon?

Lord Spandex Masher 28th Oct 2013 17:54

I'm only guessing but it might be because he can see the picture in the OP.

But it is only a guess.

Call me cynical, but that looks a very lightweight trolley for 30k lb......just a thought

mad_jock 28th Oct 2013 18:05

Surely the blue line means its not a proper one so might not be the full weight?

NutLoose 28th Oct 2013 18:13

Why would you need a bomb that big to penetrate 200ft, the Gulf War jobbies were converted artillery barrels with a little charge onboard, with nowhere to for the blast to escape it did the job.

This place is getting more like Wikileaks every day. I wonder what they'll use as a delivery vehicle?

Perhaps 60ft of concrete penetration vs 200ft?

There are not many images showing the GBU-57 and even less show the MOP next to its intended platform. That’s why the top image, taken by Jim Mumaw in Jul. 2009, is extremely interesting and rare.
Or, it's a wind up/disinfo. ;)

Surely that thing will need one under the other wing or it will just fly around in circles..................??!!:hmm:

I must email an old buddy and see if he's the photographer.

Reminds me of the joke about the wife and the thermos flask in the sex shop!

Ouch, that will smart.
You'll need more than 2 paracetamol if that hits you...

The Gulf War jobbies were a lot less effective than advertised. Post war audit is what led to new weapons being developed.
MOP is only as interim, stopgap weapon, developed to cover the capability requirement against North Korea and Iran.
It is flawed in that it lacks a void sensor so can go clean through its target and keep going, exploding ineffectively some distance later.
Its replacement will have similar penetration capabilities but will weigh a lot less, it will use velocity in order to penetrate instead of just sheer mass.

Israel's lack of this weapon is one reason they haven't attacked Iran yet, they need USA involvement to do the primary bunker busting.

But the Iranians have developed a world lead in ultra high strength concretes. So even these MOPs might not do the job.

Unless I am mistaken, all B-2 ordnance is internally carried.
It's a stealth thing, as I understand it.
Dropping one of these is likely like taking a nice 30,000 pound crap, with a likely trim adjustment immediately necessary! :uhoh:
