The operation involved "multiple precision strikes", US Central Command (CENTCOM) said in a statement, adding "there were no injuries or damage to US personnel or equipment".
The statement did not specify the location of the storage facilities.
"The strikes are part of CENTCOM's effort to degrade Iranian-backed (Houthi) attempts to threaten regional partners and military and merchant vessels in the region," it said.
The Houthis' Al-Masirah TV said there were five raids in the northwestern Amran province and two in Sanaa province, where the capital Sanaa is located.
For more than a year, the Houthis have been firing missiles and drones at Israel and at ships in the Red Sea and Gulf of Aden in what they say is a show of solidarity with Palestinians facing the Israeli genocidal war in the Gaza Strip.
