Posted on 08/22/2011 7:13:17 AM PDT by Fennie
After nearly a decade of development, the U.S. Air Force has ordered eight MOP (massive ordnance penetrator) GBU-57A/B bunker buster bombs. These 14 ton weapons cost $3.5 million each. In the last few years, several B-2 bombers have been equipped to carry these weapons (two bombs per B-2). This was apparently meant to send a message to Iran and North Korea.

..when you care enough to send the very best!
But with 0bama running things, Israel should watch their backs.
Here was an early Request for Information:
B-2/Massive Ordnance Penetrator (MOP) GBU-57A/B
Solicitation Number: 678ARSS30APR09
Agency: Department of the Air Force
Apr 30, 2009
Looks like they worked out the details.
First chuckle of the day (-:
So is this the MOABB? Or maybe the MOAB²
Congress Cancels R&D for Nuclear Earth-Penetrator Bombs

I think it was used against German sub pens.
Anyway this isn't a new idea just a refinement of an old one
MOAB I believe is not a penetrator, just a huge new version of the “daisie cutter”. If I recall correctly it is a FAE (fuel air explosive) type bomb.
I thought that bunker busters were like gigantic howitzers dropped, that will penetrate as far as they can into whatever, then they blast a projectile even further...
They will only get the message if one is actually dropped on them.
GBU 28 is not the MOAB.
GBU-43/B “Mother Of All Bombs”
Earlier versions of BBs were indeed manufactured from howitzer gun tubes and modified to penetrate-as to any use of a cannon barrel to actually fire another projectile after it pentrated, I have not heard that, but it is a novel idea....
Just for clarification:
MOAB is a guided bomb which delivers the 18,700 lb BLU-120/B warhead bomb with KMU-593/B GPS/INS. The MOAB is the largest-ever satellite-guided, air-delivered weapon in history [not the largest ever, but the largest satellite guided]. The 21,600-pound MOAB is an improved replacement for the unguided 15,000-pound BLU-82 Daisy Cutter. It is 30 feet long with a diameter of 40.5 inches. The warhead is a blast-type warhead. It was developed in only nine weeks to be available for the Iraq campaign, but it was not used in combat.
The 21,700-pound [9,500 kilogram] bomb contains 18,700 pounds of H6, an explosive that is a mixture of RDX (Cyclotrimethylene trinitramine), TNT, and aluminum. H6 is used by the military for general purpose bombs. H6 is an Australian produced explosive composition. Composition H6 is a widely used main charge filling for underwater blast weapons such as mines, depth charges, torpedoes and mine disposal charges. HBX compositions (HBX-1, HBX-3, and H6) are aluminized (powdered aluminum) explosives used primarily as a replacement for the obsolete explosive, torpex. They are employed as bursting charges in mines, depth bombs, depth charges, and torpedoes. HBX-3 and H-6 have lower sensitivity to impact and much higher explosion test temperatures than torpex. The MOAB weapon produces a very large explosive blast, with lesser fragmentation effects due to a thin-walled aluminum casing.
Contrary to some published claims, it most certainly is not an Ethylene-Oxide Fuel-Air Explosive (FAE).
The message is clear, but the messenger in chief is suspect.
Won’t believe it and don’t care....until....we use one for real!!!!
Obama, all hat no cattle.
“MOAB I believe is not a penetrator, just a huge new version of the daisie cutter. If I recall correctly it is a FAE (fuel air explosive) type bomb.”
I was thinking MOAB was going to use some kind of “slurry” explosive, was never actually dropped on anybody, but not a fuel-air explosive. Last time I remember hearing anything about it was about 2002 or 2003.
Thanks. Good info.
Figure 6 is a lousy graphic. What are the scales of the graph? Is the height or the angle or the pebble-background hourglass shaped areas meaningful? What do the rulings on the horizontal scale mean? What is that “Blast Door” thing meant to suggest?
A failed graph.
The MOAB is 30 feet, 1.75 inches (9.17 m) long, has a diameter of 40.5 inches (102.9 cm) and weighs 22,600 lb (10.3 tons) (of which 18,700 lb (8.5 tons) are high explosives.) Its blast radius is 450 feet (137.16 m, 150 yd), though the massive shockwave created by the air burst is said to be able to destroy an area as large as nine city blocks. Due to its large size and weight, it was designed to be dropped via parachute extraction out of the back of a C-130 cargo aircraft.
There's a reasonable write up here... Massive Ordnance Air Blast bomb (MOAB)
That figure has the 60’ scale on it.
It is not a graph but a dimensional comparison.
The gray area is the area the rock is broken down.
It’s bum-fiffery. What kind of rock? How well will the penetrator penetrate aggregate, sand, shale, granite? Where’s the dang engineers to make this a useful graphic?
It is a generalized comparison to past weapons.
It is not an engineering specification or sale brochure and never pretended to be one.
It’s engineering-like, number-like, science-like. IOW, it’s not real. It’s purporting to show engineering numbers and comparisons when it really isn’t. “60’”!
Many of military and ex-military engineer-types prefer to keep our mouths shut about actual numbers nad distances and dimensions.
WWII, the Grand Slam and Tallboy worked well (supersonic, very heavy conventionally-dropped bombs - see the example near Baltimore at the Armor Museum), but all too often, they did miss. Not by much, but by enough to reduce the effect, particularly against smaller targets like bridges.
B-36’s were last bombers I know of to drop the Grand Slam and its US-derivatives. Laser-aiming will improve accuracy, and conventional explosives reduce the political pressure against their use. Personally, I think the Grand Slam is prettier than these. (The C-130 super-daisy-cutter bomb is little more than box-on-a-pallet actually. It works, of course, against surface spread-out targets; it's just fugly.

“Damn! This Viagra REALLY works!”
I am not an engineer but I have read a bit about bunker busters.
I think you could use them in succession to hit the same spot to get down lower. This is certainly possible with GPS guidance or lasers.
Just a thought. These things are really nasty and the shockwave in an underground cavern would be devastating. Can you imagine one, two, three, and then four in the same spot? Each bomb working it’s way lower until the desired depth of destruction was achieved.
Or you could pulverize hard rock with the first bomb and thus provide a huge sand pile that disburses the impact of follow-on bombs.
I know that MOAB stands for Massive Ordnance Air Blast, and is not a penetrator. And that MOAB was affectionately called the Mother Of All Bombs.
That’s why I suggested MOABB might stand for Mother Of All Bunker Busters.
In any event, I don’t want to be in the same county with either one of them.
True, they may be ugly but they’re sure nice to have in your quiver. Makes for a nice means of persuassion.
