The strikes hit Taliban training facilities in Badakhshan province, "preventing the planning and rehearsal of terrorist acts," the Southern Command said in a statement.
The bombing also destroyed vehicles that it said the Taliban took from the Afghan National Army and were turning into vehicle-born explosive devices.
The strikes were carried out in part by a US Air Force B-52 Stratofortress, which dropped 24 guided munitions.
The Southern Command, which oversees US military activities in the Middle East and Afghanistan, said it continues to carry out strikes against the Taliban and its support networks in Helmand Province in the south of the country as well.
