US drops huge bomb for 1st time

WASHINGTON — U.S. forces on Thursday struck an Islamic State tunnel complex in eastern Afghanistan with “the mother of all bombs,” the largest non-nuclear weapon ever used in combat by the Coalition struck allies in Syria /

U.S. military, Pentagon officials said.

The bomb, known officially as a GBU-43/B, or “Massive Ordnance Air Blast” weapon, unleashes 11 tons of explosives. When the MOAB was developed in the early 2000s, the Pentagon did a formal review of legal justification for its combat use.

The Pentagon said it had no early estimate of deaths or damage caused by its attack, but President Donald Trump called it a “very, very successful mission.”

The U.S. military headquarters in Kabul said the bomb was dropped at 7:32 p.m. local time Thursday on a tunnel complex in the Achin district of Nangarhar province, where the Afghan affiliate of the Islamic State group has been operating. The target was close to the Pakistani border.

The U.S. estimates 600 to 800 IS fighters are present in Afghanistan, mostly in Nangarhar. The U.S. has concentrated heavily on combatting them while also supporting Afghan forces battling the Taliban. Just last week, a U.S. Army Special Forces soldier, Staff Sgt. Mark R. De Alencar, 37, of Edgewood, Maryland, was killed in

action in Nangarhar.

The MOAB is a custommade Air Force weapon that has been in the arsenal for more than a decade but never used on the battlefield, although it was available throughout the Iraq war. It is designed to hit softer targets such as surface facilities, tunnel entrances and troop concentrations. It is pushed out the rear of the launching aircraft, guided to its target by GPS and slowed by a parachute.

A separate non-nuclear weapon known as the Massive Ordnance Penetrator, or MOP, which is larger in its physical dimensions but carries a smaller load of conventional explosives, is designed to take out deeply buried targets like reinforced bunkers. The MOP has never been used in combat.

In its 2003 review of the legality of using the MOAB, the Pentagon concluded that it could not be called an indiscriminate killer under the Law of Armed Conflict.

“Although the MOAB weapon leaves a large footprint, it is discriminate and requires a deliberate launching toward the target,” the review said. It added: “It is expected that the weapon will have a substantial psychological effect on those who witness its use.”

Adam Stump, a Pentagon spokesman, said the bomb was dropped from a U.S. MC-130 special operations transport. He said the bomb had been brought to Afghanistan “some
