WASHINGTON — Late this spring, Iraqi forces fighting the Islamic State in Mosul discovered three unfired rocket-propelled grenades with an unusual feature — a heavy liquid sloshing inside their warheads. Tests later found that the warheads contained a crude blister agent resembling sulfur mustard, a banned chemical weapon intended to burn a victim’s skin and respiratory tract.

The improvised chemical rockets were the latest in a procession of weapons developed by the Islamic State during a jihadist arms-manufacturing spree without recent analogue.
Irregular fighting forces, with limited access to global arms markets, routinely manufacture their own weapons. But the Islamic State took the practice to new levels, with outputs “unlike anything we’ve ever seen” from a nonstate force, said Solomon H. Black, a State Department official who tracks and analyzes weapons.
Humanitarian de-miners, former military explosive ordnance disposal technicians and arms analysts working in areas captured from the Islamic State provided The New York Times with dozens of reports and scores of photographs and drawings detailing weapons that the militant organization has developed since 2014, when it established a self-declared caliphate in Syria and Iraq.

The records show the work of a jihadist hive mind — a system of armaments production that combined research and development, mass production and organized distribution to amplify the militant organization’s endurance and power.

At times they were exceptionally cruel.

One report noted that before being expelled from Ramadi, Islamic State fighters buried a massive explosive charge under a group of homes and wired it to the electrical system in one of the buildings.
The houses were thought to be safe. But when a family returned and connected a generator, their home was blown apart in an enormous blast, according to Snoor Tofiq, national operations manager for Norwegian People’s Aid, which is clearing improvised weapons from areas that the Islamic State left. The entire family, he said, was killed.
Craig McInally, also an operations manager for the Norwegian demining organization, described indiscriminate inventions elsewhere — including four seemingly abandoned space heaters and a generator recovered near Mosul.
The heaters and generator, useful to displaced civilians and combatants alike, were packed with hidden explosives. The bombs had been configured, Mr. McInally said, so that if a person approached them or tried to move them, they would explode.

Taken together, the scope and scale of Islamic State production demonstrated the perils of a determined militant organization allowed to pursue its ambitions in a large, ungoverned space.
Some weapon components, for example, were essentially standardized, including locally manufactured injection-molded munition fuzes, shoulder-fired rockets, mortar ammunition, modular bomb parts and plastic-bodied land mines that underwent generations of upgrades. Many were produced in industrial quantities.
The findings also included apparent prototypes of weapons that either were not selected for mass production or were abandoned in development, including projectiles loaded with caustic soda and shoulder-fired rockets containing blister agent.
While the Islamic State has been routed from almost all its territory in Iraq and Syria, security officials say that its advances pose risks elsewhere, as its members move on to other countries, its foreign members return home and veterans of its arms-production network pool and share knowledge and techniques online.
“They’re spreading this knowledge all over the world,” said Ernest Barajas Jr., a former Marine explosive ordnance disposal technician who has worked with ordnance-clearing organizations in areas occupied by the Islamic State. “It’s going to the Philippines, it’s in Africa.” He added, “This stuff’s going to continue to grow.”

Born of Insurgency

One reason for the Islamic State’s level of sophistication was clear: Its armaments programs grew out of the insurgencies fighting the American occupation of Iraq from 2003 through 2011.
Sunni and Shiite militant groups became adept at making improvised bombs, both from conventional munitions abandoned in 2003 by Iraq’s defeated military, and with ingredients that bomb-makers prepared themselves. American officials say certain Shiite groups received technical assistance and components from Iran.

Sunni bomb makers also fielded chemical weapons, sometimes by combining explosive devices with chlorine, a toxic substance with legal applications, and other times in bombs made from degraded chemical rockets or shells left from Iraq’s defunct chemical warfare program.

The Islamic State, which evolved from Al Qaeda in Iraq, built upon its predecessors’ lethal industry.

The group’s larger success since also played a role. When the Islamic State seized swaths of territory and major cities in 2014, it took control of shops and factories with hydraulic presses, forges, computer-driven machine tools and plastic injection-molding machines. It also moved into at least one technical college and university lab. This infrastructure positioned the Islamic State for an arms-production breakout.

The system was resilient, Mr. Spleeters said. One of the Islamic State’s projects, a series of recoilless launchers that gained prominence late in the battle for Mosul, in northern Iraq, was built from the ground up even while militants were pressured in combat from multiple foes on multiple fronts.

“It just kept going,” Mr. Spleeters said of the technical advancements. “They could develop stuff even as they lost territories.”
The Islamic State’s arms bureaucracy was also disciplined. Detonating cord used in improvised explosive devices was measured and allotted down to the centimeter, Mr. Spleeters said. When a stock ran out, management would fill out a request form for more. The material would be resupplied.
Mr. McInally said the group’s armament production appeared centralized and carefully considered.
As de-miners have found weapons, he said, they have routinely encountered improvised devices with a modular design that allowed for the Islamic State’s fighters to choose from uniform parts and assemble devices quickly. The separate parts were issued distinctly, to be combined before use.

It’s impressive.”

The New York Times is withholding technical details of weapons and explosive mixtures described in this article to prevent the spread of information useful to copycats.
Mr. Barajas said the explosive charges themselves were further standardized — via a so-called homemade explosive with a recipe the group tweaked and produced at an industrial scale.

The mixture, he said, is a widely known combination of ammonium nitrate fertilizer and aluminum with a long history of use in many conflicts, including in Iraq. But the Islamic State improved the explosive with the addition of another material that makes it easier to detonate.
The Times previously documented the Islamic State’s importation of large amounts of ammonium nitrate from Turkey, along with sections of heavy pipe.

Mr. McInally said the group also standardized other items: supplemental charges for mortar rounds to extend their range; a common fuze with a spring-loaded striker assembly machined from an over-the-counter bolt; and an improvised bomb — he said de-miners refer to it as a land mine — that was fielded in a standard-sized plastic tub.

The mines resemble an Italian-made antipersonnel mine called the VS-50, though the Islamic State’s version is much larger, prompting de-miners to dryly refer to it as the “VS-500.”
As time passed, newly produced VS-500 mines became increasingly water-resistant, extending their life in the ground. Similarly, the striker fuzes that the Islamic State has fielded show signs of being made resistant to moisture and rust.
The first-generation land mines, Mr. McInally said, were not well made. “They didn’t weather well,” he said. But by the time the Islamic State was defeated in Mosul, he said, it had improved the design and salted the battlefield and villages with weapons “that last a long, long time.”
The Islamic State has also engaged in organized scavenging, including collecting dud American-made bombs dropped by coalition warplanes and repurposing their explosive power. One set of photos provided by a de-miner show how the group set up an open-air chop shop to cut open unexploded American aircraft bombs and remove the explosive inside.
These explosives tend to be more powerful and more reliable than homemade explosives. Mr. Barajas said the Islamic State put what it had scavenged to priority use — in suicide attacks.

“Every time I’d run an explosive test on the ordnance buried in the ground, if I found it connected to the pressure switches, it would come back as ‘homemade explosives,’” he said. But the explosives in suicide vests and belts, he added, were compounds, including RDX and TNT, extracted from conventional ordnance.
Not all of the Islamic State’s developments have been effective. When experimental designs failed, Islamic State engineers made changes or moved on.
According to an American government official who examined an analysis of the rocket-propelled grenade filled with blister agent, the weapons would probably not fly a predictable and accurate path. X-rays, he said, showed that they had been only partly filled, and were unbalanced.
Similarly, the Islamic State seemed to struggle with a series of mortars filled with caustic soda, or lye, a strongly alkaline compound that is sold in a heavy flake form and sometimes used as a drain cleaner.
Dozens of locally produced mortar projectiles filled with caustic soda were found by de-miners in Manbij, Syria, in late 2016. Mr. Barajas analyzed the discovery.

“Caustic soda is extremely hazardous. It’ll burn your skin,” he said. “If you inhale it, it’ll cause death.” But the material is also corrosive, so much so that it damaged the interior of the shells the Islamic State had used to hold it.
He said that the Islamic State tried loading 120-millimeter mortar rounds with caustic soda, but that the munitions rusted to the point of exuding salts. They could not be safely fired. “I think once they got this bad reaction, they moved away from this,” Mr. Barajas said.


Put to Brutal Use

Many of the Islamic State’s bombs have been used against the military and police forces fighting it. Aso Mohammed, a Kurdish de-miner with the Swiss Foundation for Mine Action, said that by his estimates, improvised explosive devices have been responsible for 60 percent of casualties of Kurdish pesh merga soldiers in Iraq’s north.
But other uses were consistent with the Islamic State’s well-documented disregard for international law and humanitarian concerns evident in their abductions, public executions, production of snuff films and bombings of public spaces.
In a prepared statement, the American military in Baghdad noted that coalition forces have recovered and destroyed booby-trapped teddy bears. De-miners and their supervisors in Iraq frequently trade reports and details of other Islamic State-made booby traps, among them dolls, stuffed animals and plastic trucks, as well as teapots, fire extinguishers, flashlights and copies of the Quran.
Two de-miners, Steve Kosier and Mr. Mohammed, of the Swiss demining organization, said that the Islamic State’s locally made weapons had evolved in a predictably sinister fashion. Improvised devices that once were connected to a single plate that would cause the bomb to explode were later in the campaign connected to several plates — an adaptation intended to slow de-miners as they cleared buildings, roads and terrain.
Mr. Kosier said he had disabled one makeshift bomb that “had four pressure plates surrounding the container with a 9-volt battery for each plate.” Each plate was connected by a separate electrical circuit to a container of homemade high explosives, which in turn had an “anti-lift device” beneath it — essentially a booby trap added to an already complex booby trap.
The ambition behind such a trap, de-miners said, is to kill people trying to make the Islamic State’s former turf safe.
