US Central Command said C-130 transport aircraft had made "multiple" drops of supplies provided by Kurdish authorities in Iraq.
US air strikes have helped push back IS in the town near the Turkish border, the BBC reports.
Correspondents say the airdrops are likely to anger key US ally Turkey.
The drops of supplies provided by Kurdish authorities in Iraq were "intended to enable continued resistance against Isil's attempts to overtake Kobane," CentCom said in a statement. IS is also referred to as Isil and Isis.
All the aircraft involved had returned safely, it said.
US forces have conducted more than 135 air strikes against IS in Kobani.
"Combined with continued resistance to Isil on the ground, indications are that these strikes have slowed Isil advances into the city, killed hundreds of their fighters and destroyed or damaged scores of pieces of Isil combat equipment and fighting positions," the statement said.
However, it added that IS fighters continued to threaten Kurdish forces' ability to resist and hold the city.
"Kobane could still fall."
On Sunday, Turkish President Recep Tayyip Erdogan said he would not allow Kurdish fighters to receive any transfers of American arms.
