The U.S. Air Force is shelving plans to retire the aging A-10 Warthog aircraft, a heavily armored tank killer, because of its role in the fight against Islamic State, online publication Defense One reported on Wednesday, citing unnamed Pentagon officials.

The 40-year-old ground attack aircraft is popular with soldiers, Marines — and some U.S. lawmakers.

Defense One quoted the Air Force officials as saying that, while the A-10 would still need to be retired, the service would put aside immediate plans to take it out of service because of the important role it is playing in combating Islamic State.
