New Secretary of Defense James Mattis released a memo this week calling for a review of the F-35 program and to compare it to the operational capabilities the F-18 Super Hornet.

Today the Marine Corps’ Deputy Commandant of Aviation, Lt. Gen. Jon Davis said the review will include Marine Corps aviators and aircraft.

Speaking to reporters in Washington, D.C., Lt. Gen. Jon Davis said the review, commissioned by Defense Secretary Jim Mattis on Jan. 26, would study the two aircraft “apples to apples” to determine whether the 4th-generation Super Hornet can fill the shoes of the brand-new F-35C.

“Really, it is — looking across the mission sets — does a Block 3 Super Hornet match up, compare to an F-35C,” Davis said. “It’s for the carrier air wing of the future.”
