On Wednesday evening, a pair of US Air Force B-2 Spirit bombers carried out air strikes against the Islamic State in Libya, US defense officials said on Thursday.
The Spirit of Pennsylvania and Spirit of Georgia, bombers attached to the 509th Bomb Wing at Whiteman Air Force Base in Missouri, dropped more than 100 precision-guided munitions on two Islamic State camps approximately 28 miles southwest of Sirte.
According to U.S. Air Force spokesman Col. Patrick Ryder, the B-2 bombers were used because of their range and payload capacity, particularly the B-2s ability to carry up to 80 GBU-38, a 500 pound JDAM.
Additionally, the B-2, with a payload capacity of 40,000 pounds, is able to loiter for long periods of time, which gives it “persistence and flexibility if and when additional strikes are warranted,” US Air Force spokesman Capt. Mark Graff said in a statement.
The pair of B-2s flew for 34 hours at an operating cost of approximately $130,000 per flight hour. That comes out to roughly $4.4 million a piece or $8.8 million for the duo. Additionally, there were roughly 15 aerial refueling aircraft involved in the mission, not to mention the cost of 100 JDAMs.
The B-2’s last combat deployment was in March 2011 when three aircraft were used in Operation Odyssey Dawn over Libya. Currently, there are 20 B-2’s in the US Air Force’s inventory.
