The signature weapon of the 9/11 Era is lethal, easily concealable and maddeningly easy to construct. But the greatest danger from the improvised explosive device — what ensures its endurance far from the battlefields of Iraq and Afghanistan — lies in how cheap it is.
The improvised explosive device, or IED, isn’t a bomb. It’s a category of bombs, and within that category, insurgent MacGyvers construct makeshift bombs from whatever they have at hand. The Iraqi insurgency often relied on looted stockpiles of artillery shells or mines, juryrigged together and detonated from a cellphone. In Afghanistan, insurgents can’t similarly rely on abandoned weapons depots for their explosives, so they construct bombs using ammonium nitrate fertilizer, detonated by a fuse or using wooden plates that complete a hidden circuit when a soldier inadvertently steps on it. Insurgent allies in the security services of states like Iran or Pakistan add more sophisticated bomb ingredients or aid with logistics.
The common theme: all the ingredients for the bombs are inexpensive enough to remain in mass production, even when the U.S. attacks an insurgency’s revenue stream. And they’re vastly cheaper than the vehicles they destroy, the gear used to find them, and the troops they maim and kill.
Determining just how expensive they are is difficult, owing to all of the different components in the bombs. But according to the Pentagon’s bomb squad, the average cost of an IED is just a few hundred bucks, pocket change to a well-funded insurgency. Worse, over time, the average cost of the cheapo IEDs have dropped from $1,125 in 2006 to $265 in 2009. A killing machine, in other words, costs less than a 32-gig iPhone.
Dollar figures for the bombs are hard to come by — it’s not like there’s a Consumer Reports for black-market mines — but the Joint Improvised Explosive Device Defeat Organization, known as JIEDDO, shared some estimates with Danger Room about how much Afghanistan’s bombs cost. Those estimates, publicly released for the first time, will have to serve as a proxy for the costs of the weapons worldwide.
The most plentiful types of bomb from 2009 — the most recent available figures for the myriad types of bombs — were, unsurprisingly, the cheapest. On average, a “victim-operated” bomb — one set to explode when its target or a civilian inadvertently sets it off — cost a mere $265. (That seems remarkably high for bombs that can be as simple as a bunch of fertilizer chemicals, wires and a pressure plate made out of two blocks of wood, but that’s what JIEDDO says.) Those types of bombs accounted for 57.9 percent of homemade bomb incidents in 2009. The next most plentiful category of bomb, those set off with command wires leading from the device, also cost $265 on average in 2009, accounting for another 23.8 percent of attacks.
As the bombs get more difficult to construct or operate, the costs rise. Bombs activated with a remote detonator like a cellphone cost a mere $345 and accounted for a surprisingly small — 12.6 percent — of attacks, perhaps owing to the U.S.’ hard-won ability to jam the detonator signal. (One would imagine the major cost component is the cellphone.) For insurgents to turn a car into a bomb or convince someone to kill himself during a detonation — or both — the cost shoots up into the thousands: $10,032 for a suicide bomber; $15,320 for a car bomb; nearly 19 grand to drive a car bomb. All together, those relatively expensive attack methods accounted for fewer than six percent of bomb attacks in 2009.
Most of those bombs have gotten cheaper to produce. In 2006, victim-operated IEDs cost an average of $1,125. Command-wire bombs were $1,266. Remote detonation bombs? The same. And as the costs dropped, victim-operated and command-wire detonated bombs skyrocketed. Back in 2006, they accounted for merely 21.3 percent and a piddling 1.9 percent of all bomb attacks, respectively.
But the sophisticated bombs have gotten more expensive. Car bombs cost $1,675 on average in 2006 — which seems absurdly low, given the cost of one involves acquiring and then tricking out a car. And the going rate on suicide bombers appears to have risen, from $5,966 in 2006 to nearly double that in 2009. Accordingly, both accounted for over 16 percent of IED attacks in ‘06. And JIEDDO says it has preliminary reporting indicating that suicide bombers cost $30,000 as of January.
It’s also worth mentioning that the number of IEDs in Afghanistan has mushroomed: from 1,952 in 2006 to 5,616 in 2009. All told, since the Afghanistan war began, homemade bombs have killed 719 U.S. troops and wounded 7,448.
