The U.S. military announced coalition warplanes killed the Taliban militants responsible for the deaths of 30 U.S. military personnel last Saturday.
The news came just one day after President Obama met two aircraft carrying the remains of those service members.
America's top military commander in Afghanistan says F-16 jets killed the insurgents on Monday.
"At approximately midnight on 8 August, coalition forces killed the Taliban insurgents responsible for this attack against the helicopter," said Marine Corps Gen. John Allen.
"All of these operations generate intelligence," Allen said, including about those who fled the site of the crash.
"We tracked them as we would in the aftermath of any operation, and we dealt with them with a kinetic strike, and in the aftermath of that we have achieved certainty that they, in fact, were killed in that strike," Allen said.
He spoke by video from his Kabul headquarters.
In a separate statement, the military said the strike killed Taliban leader Mullah Mohibullah and the insurgent who fired the rocket-propelled grenade at the helicopter.
"This does not ease our loss, but we must and we will continue to relentlessly pursue the enemy," Allen said.
The crash was the deadliest single loss for U.S. forces in the nearly 10-year Afghan war.
Intelligence gathered after the Chinook helicopter was shot down led coalition forces to the insurgents.
