Mother Of All Bombs (MOAB) – Simplified Explaination

MOAB – (GBU-43/B) – Massive Ordnance Air Burst – (Commonly known as Mother of all bombs)

Talking about bombs, I’m going to drop this bomb article about something very illuminating. This article focuses on MOAB.

So what exactly is “MOAB”?
It is a large yield bomb developed for the US military by Albert L. Weimorts. It was designed in the year 2002 and was produced in the year 2013. Fifteen (15) MOAB’s were built. It was first dropped in combat on 13 April 2017 Airstrike against the Islamic State of Iraq and the Levant (ISIL) militants in Afghanistan.

That’s about the history. Now, we’ll be emphasizing meticulously on what MOAB is and how exactly it works which is the crucial bit of this article. First, let’s ascertain the minute details of what a MOAB is.

This bomb is a non-nuclear weapon. And yes! If knowing more about nuclear bombs is your motive, we’ll make a separate blog post on it so, do comment if you wish to know more. Also, subscribe to the newsletters and you will be notified when it gets published.


Cutting off the deviation, the ultimate non-nuclear bomb (MOAB) is one of the biggest assets of the USA army. The total weight of this bomb is 9800 Kilograms which is 21600 pounds. This bomb is an air burst bomb which means it bursts before touching the ground surface. It bursts around 6 feet above the ground level. The exact length of this bomb is 30 feet 1.75 inches which is approximately 9.189 meter and the diameter is 40.5 inches which is approximately 1 meter.

I did mention that the bomb is huge, right! so how do you think a bomb that big is fired?
It definitely can’t be fired with the traditional aircrafts. So the alternative is that it must be carried by a cargo plane like the MC-130 Cargo plane. The bomb initially falls with a parachute to decelerate its descent and give the aircraft enough time to get away safely. After which a GPS system guides the bomb to its target.

This bomb is definitely big, yet it is not the world’s biggest bomb.
Russia has a much bigger bomb whose capacity is 4 times that of a MOAB and it’s named as FOAB (Father of all Bombs). Besides this, the US Military had also developed a Bomb in the year 1950 which was named T-20 and it was massive. It was humongous and it weighed around 43600 pounds.The previous biggest bomb was Daisy Cutter and is used in mines for explosions. It is relatively cheap and the effect is quite less.


More details about MOAB
Now, coming back to MOAB. After being produced in the year 2003, it was not used until 2017 came in.
It uses the technology which is called as TNT (TriNitroToluene). To improve the efficiency in TNT, 20% of aluminum powder is being mixed, after which the time required to reach the peak pressure also reduces. This literally makes it more effective. But mind you, it is incomparable to Nuclear Bombs. The yield that you get from nuclear bombs is much higher and therefore its effect is also much higher when compared to a MOAB of the same size. This MOAB is efficient when it comes to destroying caves, bunkers, small war vehicles, etc. The range of MOAB is a one-mile radius. This doesn’t mean it’ll completely destroy everything that falls within that radius. It also depends on the strength of the other structures.


One of the amazing facts of this bomb is that it is GPS guided which means, after being fired from a plane, the bomb can change its direction using the flaps that are present in the body of the bomb. The flaps are connected with GPS satellites. The direction of the bomb can be guided with flaps by which the bomb can precisely hit its target. Hence calling it a smart bomb will not be wrong.

One more advantage of this bomb is that it blasts around 6 feet high above the ground level due to which the effect is much higher when compared to bombs that blast after hitting the ground surface, in which the earth absorbs a lot of energy.


This is pretty much everything about MOAB.

I hope that this article has helped you understand the technology instilled in MOAB. Stay tuned for more informative posts.

Thank you, hope you liked it. Please do comment if you have any queries regarding this topic, and you can also suggest me to write about any other technology topic and I will consider it.
