GBU-43/B "Mother Of All Bombs" 
MOAB - Massive Ordnance Air Blast Bomb


The GBU-43/B is large, powerful and accurately delivered. high explosive.
The GBU-43/B Massive Ordnance Air Blast Bomb [MOAB] weapon is a 21,000 lbs
total weight GPS-guided munition with fins and inertial gyro for pitch and
roll control. It is probable that this munition was initially nick-named the
"Mother Of All Bombs" with the retronymic expansion of MOAB following later.


On 11 September 2007 the Russian military announced that it had tested what
it called the "Father of All Bombs". Described as the world's most powerful
non-nuclear air-delivered munition, the Russian military claimed it was four
times more powerful than the American "Mother Of All Bombs." While the
Russian bomb was reported to contain 7.8 tons of "thermobaric" explosive,
compared to the more than 8 tons of explosives in the American bomb, the
Russian bomb was said to use more highly efficient explosive, with a yield
equivalent to 44 tons of TNT. The bomb was reported to have a blast radius
of 300 meters, double that of the American bomb, while the temperature at
the epicenter was also reported to be twice as high.

In 1991 Saddam Hussein conquered Kuwait and postured with threats to deliver
the "Mother of All Battles". Mother of all Battles [Umm Al-Ma'arik / Um
El-Ma'arek] -- the Arabic "mother of" is a figure of speech for "major" or
"best". The original "Mother of All Battles" was the Battle of Qadisiya
[Battle of al-Qadisiyya] in 637 CE, in which Islamic Arabs defeated the
Persians. Saddam Hussein's "Mother of All Battles" turned intot, among other
things, the "Mother of All Retreats", the "Mother of All Blowouts", "the
mother of all Marine operations", 650-slide "mother of all briefings", and
so forth. 

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). Some initial reports had stated
that this replacement for the BLU-82 bomb uses more of the slurry of
ammonium nitrate and powdered aluminum used in the BLU-82. Other reports
indicated that the MOAB might use tritonal explosive as opposed to the
gelled slurry explosive of the BLU-82. Contrary to some reports, it is not
capable of deep ground penetration. 

Like the BLU-82, the MOAB rests in a cradle on an airdrop platform inside a
C-130 aircraft. Due to the size of the ordnance, the item is extracted from
either an MC-130 Talon II or "Slick" C-130 Hercules by way of a parachute. A
drogue parachute extracts the weapon, cradle and platform-and the weapon is
quickly released to maintain maximum forward momentum. The grid fins then
open and begin guiding the weapon to its target. 

The MOAB weapon is based upon the same principle as the BLU-82 "Daisy
Cutter", except that it is larger and has a guidance system. The weapon is
expected to produce a tremendous explosion that would be effective against
hard-target entrances, soft-to-medium surface targets, and for
anti-personnel purposes. Because of the size of the explosion, it is also
effective at LZ clearance and mine and beach obstacle clearance. Injury or
death to persons will be primarily caused by blast or fragmentation. It is
expected that the weapon will have a substantial psychological effect on
those who witness its use. The massive weapon provides a capability to
perform psychological operations, attack large area targets, or hold at-risk
threats hidden within tunnels or caves. 

The weapon is intended to have a high altitude release, allowing for greater
stand-off range for the delivery vehicle. Following deployment from the
aircraft via drogue parachute, the MOAB weapon is guided approximately 3
nautical miles through a GPS system (with inertial gyros for pitch and roll
control), JDAM actuators, and is stabilized by series of fixed wings and
grid fins. The weapon, which uses the aircraft's GPS prior to launch, takes
several seconds to reconnect to the GPS signal after it has been deployed,
which is normal for GPS weapons. 

The US Air Force developed the satellite-guided Massive Ordnance Air Blast
Bombs (MOAB) as a successor to the the 15,000-lb. "Daisy Cutters" used in
Vietnam and Afghanistan. The Air Force is said to call MOABs (pronounced
MOE-ab) the Mother Of All Bombs. As with the earlier Daisy Cutter, these
huge bombs are dropped out of the rear of the C-130 cargo plane. Unlike the
Daisy Cutter, the MOAB falls to the ground without the use of a retarding
parachute. As a result, the aircraft releasing the bomb can fly at higher
altitudes, thus making it safer for US pilots. 


MOAB Chronology


In early 2002, the AF Munitions Directorate began to investigate the
possibility of upgrading the large BLU-82 weapon with a guidance and control
capability. Such an upgrade would allow the delivery aircraft to fly higher
for better survivability and safety from the weapon's blast. It would also
give the weapon greater range and accuracy, opening the door to additional
target sets. After several design iterations gave the weapon a more
aerodynamic shape, the current configuration of the MOAB was born. Work on
the program began in 2002 and was set for completion in 2003. 

Within nine months, the MOAB program went from development contract award to
the completion of three highly successful flight tests. During the flight
tests, the MOAB detonated upon contact with the ground. The program
culminated in the successful demonstration of a suite of technologies
supporting large weapons. 

Testing began at Eglin as part of an Air Force Research Lab Technology
Demonstration Project. With support from the Defense Threat Reduction
Agency, Natick Army Soldier Center, Naval Coastal Systems Station- Panama
City, Air Transportation Test Loading Agency, Detachment 1 of the 46th Test
Wing at Hurlburt Field, and Dynetics, Inc., directorate engineers rapidly
and successfully designed, fabricated, integrated, and tested the huge MOAB
weapon. 

On 11 March 2003 he Air Force tested its Massive Ordnance Air Blast (MOAB)
weapon at the Eglin Air Force Base Air Armament Center's western test range,
dropped from a C-130.

Eglin Air Force Base's Air Armament Center conducted the second live test of
the largest conventional bomb in the US inventory at approximately 2:30 p.m.
EST 21 November 2003. Designated the GBU-43/B, the 21,700-pound bomb was
launched from an MC-130E Combat Talon I aircraft flown by a crew assigned to
Eglin's 46th Test Wing. One objective was to collect more data and provide
it to the user to assist in targeting. Also, the Air Force wanted to certify
MOAB on the Combat Talon I aircraft as previous launches had been made from
the MC-130 Combat Talon II.
