- The Air Force says it is dropping bombs 'faster than we can replenish them' in fight against ISIS
- More than 20,000 bombs and missile have been dropped over the past 15 months
As the U.S. ramps up its campaign against the Islamist terror group in Iraq and Syria, the Air Force is now "expending munitions faster than we can replenish them," Air Force chief of staff Gen. Mark Welsh said in a statement.
"B-1s have dropped bombs in record numbers. F-15Es are in the fight because they are able to employ a wide range of weapons and do so with great flexibility. We need the funding in place to ensure we're prepared for the long fight," Welsh said in the statement. "This is a critical need."
The bombing campaign has left the U.S. Air Force with what an Air Force official described as munitions depot stocks "below our desired objective."
The official told CNN that the Air Force has requested additional funding for Hellfire missiles and is developing plans to ramp up weapons production to replenish its stocks more quickly. But replenishing that stock can take "up to four years from time of expenditure to asset resupply," the official said.
"The precision today's wars requires demands the right equipment and capability to achieve desired effects. We need to ensure the necessary funding is in place to not only execute today's wars, but also tomorrow's challenges," the official said.
The Air Force's publication of the number of missiles and bombs dropped comes amid continued criticism from Republicans -- in particular those running for president -- who insist the Obama administration has been too timid in the fight against ISIS, with many on the right calling for the U.S. to loosen the rules of engagement and lead a more aggressive fight against the militant group.
American pilots have fired weapons in less than half of the nearly 18,000 sorties they have in the first 10 months of 2015, according the latest figures available.
That's up from 2014, when pilots fired their weapons just one third of the time.
