MOAB suspected in Basra blasts

A SERIES of big explosions have been reported near the southern Iraqi city of Basra.

"We can see huge explosions and fireballs on the horizon towards Basra," Reuters correspondent David Fox said from a vantage point overlooking the frontier about 50km south of Basra.

The scale of the explosion suggests a Massive Ordnance Air Blast (MOAB) bomb may have been deployed.

The 9450kg MOAB has supplanted the Daisy Cutter in the US arsenal as the world's largest conventional bomb.

Explosions were also heard in or around the main northern Iraqi city of Mosul early Friday, Al-Jazeera television reported from the scene.

The blasts occurred around half an hour after raid sirens sounded over the the city for the fourth time since the US-led war on Iraq began early Thursday.

LOL...how about an "It's not Impossible..." BUMP!

[New Horizon]

Nope. Nor is the Daisy Cutter. Neither are FAE's.

[Paradox]

Nope, it is a "conventional" high explosive bomb. It just goes BOOM. The FAE's are the ones that disperse an aerosol and THEN ignite this big cloud with a charge.

But hey, dont kid myself, a MOAB would surely blow the oxygen out of an area as effectively, just by brute force I'm sure.

[Darling Lili]

Are there any credible news outlets reporting this?

[Ford Fairlane]

OK, I must have misplaced a brain cell somewhere

The 9450kg MOAB has supplanted the Daisy Cutter in the US arsenal as the world's largest conventional bomb.

That would sound *so* much better if not expressed in metric.

[Obi-Wandreas]

I used to bullseye womp rats with my T-12 back home.


Sorry to nitpick, but it was a T-16

[Paradox]

OK, I must have misplaced a brain cell somewhere

Its not your fault, I was similarly mistaken. It is because many sources mistakenly refer to the MOAB and the Daisy Cutter as Fuel Air devices. Even "reliable" looking sources online.

[ThePythonicCow]

I thought that the MOAB is fuel air as well, and indeed corrected someone on that here a few days ago.

But according to a post by Paul Rogers on www.opendemocracy.net, it is not:

The Mother of all Bombs – how the US plans to pulverise Iraq
Paul Rogers

A devastating new weapon will be part of the US’s massive assault on Iraq. Paul Rogers, openDemocracy’s international security correspondent, explains what it is, how it developed, and why its use is likely to destroy civilian lives in their thousands.




As the United States Air Force (USAF) builds up its deployments of aircraft in the Middle East, it has emerged that a huge new bomb has recently been developed that will be used in the war against Iraq. It is the most powerful conventional bomb to be deployed anywhere in the world and is described as having an effect as devastating as that of a small nuclear artillery shell. The bomb, known as the Massive Ordnance Air Burst (MOAB) weapon, contains 9.5 tons of a very powerful explosive. It is intended primarily for targeting against infantry and armoured vehicles. It can kill people within several hundred metres of the point of detonation, and cause lung damage and other injuries over an even wider area. The MOAB is an airburst weapon designed to be used against surface targets or shallow trenches, not deep underground bunkers. It represents a more powerful development of a 7.5 ton bomb, the BLU-82, originally produced during the US war in Vietnam; there, it was employed, among other things, for instant clearance of forest to provide helicopter landing zones. The BLU-82, sometimes called Big Blue or even daisy-cutter, was kept in the USAF weapons inventory after the end of the Vietnam war in 1975. The BLU-82 was subsequently used to attack Iraqi infantry and trenches in the 1991 Gulf war, and more recently in Afghanistan. There, it was deployed against cave entrances and in open country around the mountains of Tora Bora. Journalists who visited areas where the bomb had been dropped reported scenes of extraordinary devastation. Transports of death Both the MOAB and the BLU-82 have been incorrectly reported to be fuel-air explosive (FAE) weapons, where a cloud of a hydrocarbon-based aerosol is created that is then detonated. Because such an explosive uses the oxygen in the atmosphere as the oxidant, it is more ‘efficient’ than many high explosives, but it also requires relatively calm weather conditions and is difficult to use in quantities of more than a ton. Even so, a modern FAE is a very dangerous and damaging weapon, especially when used against buildings. There are unconfirmed reports that the Israelis used such weapons during the siege of Beirut in 1982. In that conflict, some 20,000 people died in and around the city. The BLU-82 and the MOAB are, in fact, much larger and more powerful weapons even than an FAE. They are based on a mix of ammonium nitrate and powdered aluminium in an aqueous suspension or slurry, with a binding agent to hold the materials together before detonation. The effect of the BLU-82 is astonishing, and rare film shows a detonation, shock wave and subsequent mushroom cloud very similar to a small nuclear weapon, even if it is actually a conventional bomb. When used in war, the BLU-82 is ejected from the back of a C-130 Hercules transport aircraft at low altitude and is parachuted down until it is detonated a few feet from the ground. By contrast, the larger MOAB bomb is satellite-guided so that the plane can drop it from a much greater altitude. It is not easy to give an indication of just how destructive such weapons are. Because of the advanced nature of the explosive, the MOAB probably has a blast equivalent of at least 20 to 30 tons of second world war-vintage high explosives. Weapon of the strong To convey the scale of destruction the MOAB can inflict, a comparison with the Provisional IRA (PIRA) bombing campaign in British city-centres in the early and mid-1990s is instructive. Two bombs were detonated in the City of London (1992 and 1993), a third in London’s Docklands area (1996), and a fourth in the retail heart of Manchester (also in 1996). Damage on each occasion cost many hundreds of millions of pounds, and took up to two years to repair. These bombs, though, were crude fertiliser-based devices weighing up to a ton, nothing like as devastating as a commercial high-explosive. By comparison, a single MOAB would be at least fifty times as powerful as any of the PIRA bombs. Furthermore, the PIRA bombs were intended primarily to cause economic damage, so casualties were relatively low. When the Tamil Tigers in Sri Lanka detonated a bomb of a similar size in the central business district of Colombo in 1996, nearly 100 people were killed and over 1,000 injured. The MOAB would be used in Iraq primarily and intentionally to cause high casualties. While US sources may say that the MOAB would be used in open country against the Iraqi military, there is every indication that the Iraqis will concentrate their forces in and around cities, especially Baghdad.

As noted in my post just above, the MOAB is satellite guided, so can be dropped from high altitude. We would not have to have the low-level air superiority needed to drop the BLU-82 daisy cutter.

[The_Sword_of_Groo]

Thanks for the info

[Slewfoot]

The test drops were from a c130 just like a daisycutter, but the Moab was designed to fit the bombay of a b2. The holdup on dropping them from bombers is the orignal bomb racks in our big bombers are not designed to hold anything this heavy. As soon as we get a bomber modified to carry them (if we havn't already) we will be able to drop them from higher attitude. Cargo planes with their back door open arn't pressurized and can't operate a high allitudes.

the world's largest conventional bomb

No, there have been bigger before. This is the world's largest mass-produced conventional bomb.

[Ford Fairlane]

I commented to someone a few days ago, you could make a pretty nasty fuel air bomb with a pressurized tanker trailer, the appropriate valves, a few rupture disks, and various small parts from the local industrial supply house

[Slewfoot]

attitude. allitudes. = altitude ... opps

[struwwelpeter]

Well, not to nitpick, but military transports have on-board oxygen and "walk around" bottles for operations above 15,000 feet, such as HALO.

[capitan_refugio]

One would use a fuel-air explosive to take out, for instance, an Hamas parade in downtown Beirut.

[Beck_isright]

Damn, and not video or live coverage.

MOAB = Mother of all Bullshiite

Ever since I saw the flashy picture of it, and certainly when the video of the blast came out, I felt it was mostly for publicity. I'm no military expert, just a hunch.
