The ongoing US-Iran conflict is putting significant pressure on American weapons supplies.
The heavy use of precision missiles and air-defence interceptors has raised questions about how quickly the United States can rebuild its stockpiles.
The issue has become an important part of the debate over US military readiness.
War costs reach billions
The Congressional Budget Office said the war had cost the United States about $38 billion through August 1.
It also estimated that the cost could increase by roughly $3 billion every month if the conflict continues.
The Pentagon inspector general had earlier placed the cost at $33.4 billion through June 19.
Advanced weapons heavily used
The war has consumed large numbers of advanced weapons.
Among them are long-range precision missiles and air-defence interceptors.
Reuters reported that the US military had used virtually all of its stock of certain precision missiles.
The use of Patriot and THAAD interceptors has also reduced available supplies.
Experts have warned that rebuilding some weapons stocks could take years.
Washington rejects shortage concerns
Despite the reports, the Trump administration has rejected the suggestion that US forces are running out of ammunition.
Pentagon officials have maintained that the military has enough weapons to carry out its current mission.
The administration has also disputed concerns that the conflict has left the US military without adequate resources.
US bases suffer damage
The conflict has also caused damage to American military facilities in the Middle East.
The Pentagon inspector general reported hundreds of damaged or destroyed buildings and other structures.
Aircraft and other military equipment have also suffered losses.
These damages add another layer to the cost of the prolonged conflict.
Readiness becomes a concern
The pressure on weapons stocks has raised questions about America’s ability to respond quickly to another major conflict.
US military resources have already been shifted toward the Middle East.
Some analysts have warned that continued fighting could further stretch American forces and reduce available reserves for other theatres.
For Washington, the challenge is no longer only the cost of the war.
It also involves replacing sophisticated weapons while maintaining military readiness elsewhere.
