Iran War Costs Reach $43.6 Billion, Estimate Says
The United States says its war with Iran has become very expensive.
A new estimate puts the cost at $43.6 billion by September 3.
Much of the money has paid for weapons, ships, planes, bases, and medical care.
Missile interceptors, which protect against incoming missiles, cost a large share of the total.
The Pentagon says 18 American service members have died and more than 830 have been wounded.
Iranian attacks also damaged buildings at American bases in several Middle Eastern countries.
The war has reduced supplies of some important defensive missiles.
Some lawmakers want the Pentagon to explain the spending more fully.
The administration is asking Congress for a much larger military budget and additional war funding.
U.S. Central Command estimates the Iran war cost $43.6 billion through September 3.
A Congressional Budget Office report estimated $38 billion through August 1 and about $3 billion in monthly future costs.
U.S. weapons costs rose to $28.1 billion, driven largely by expensive missile interceptors.
The Pentagon has reported 18 American troops dead and more than 830 wounded.
