The Trump administration has planned a meeting with the leadership of defense contractors at the White House on Friday to urge the companies to accelerate the production of American-made weapons.
“The President will continue to call on these U.S. companies to more speedily build American-made weapons, which are the absolute best in the world," White House press secretary Karoline Leavitt said in a statement.
Leavitt said the meeting was "scheduled weeks ago," before the U.S. began strikes in Iran. The news of the meeting was first reported by Reuters.
It comes as Trump said on social media Monday that the U.S. has "a virtually unlimited supply of these weapons."
Leavitt said the “U.S. military has more than enough munitions, ammo, and weapons stockpiles to continue demolishing the Iranian regime and achieve the goals of Operation Epic Fury.”

"In attack - what is needed are three things: first of all, determination, secondly, initiative, and thirdly, cunning. We have such in abundance, as the enemy has already discovered, and I tell you, citizens of Israel, he will discover even more," Netanyahu added.
