The assessment warns of significant issues with the warplane

The $400 billion program is at risk of not reaching full combat capability

(CNN) —  

The F-35 Joint Strike Fighter program is drawing sharp criticism from the Pentagon’s top weapons tester, who warns the aircraft is “on a path of failing to deliver” its full combat capability.

The sobering review of the US military’s $400 billion program comes despite its achieving several major development milestones this month. The single-engine, fifth-generation F-35 fighter jet is touted as the future of military aviation: A lethal and versatile aircraft to replace the aging fleet currently used by all three military branches.

An Aug. 9th memo from Michael Gilmore, the Defense Department’s director of operational testing, to defense officials details the tester’s concerns.

Dated just one week after the Air Force declared its version of the F-35 ready for initial combat operations, Gilmore wrote that the advanced aircraft continues to demonstrate limitations related to its software, data fusion, electronic warfare and weapons employment, according to Bloomberg News, which first reported the memo.

“Achieving full combat capability with the Joint Strike Fighter is at substantial risk” of not occurring before development is supposed to end and realistic combat testing begins, he wrote in the memo to Air Force Secretary Deborah Lee James; Gen. David Goldfein, the service’s chief of staff, and Frank Kendall, the Pentagon’s acquisitions chief, according to Bloomberg.

The first versions of this long-range heavy bomber flew in 1954. A total of 744 were built, the last of those in 1962. The Air Force maintains 58 B-52s in the active force and 18 in the Reserve. A single B-52 can carry 70,000 pounds of mixed munitions, including bombs, missiles and mines. The eight-engine jets have a range of 8,800 miles.

First delivered to the Air Force in 1956, the C-130 remains one of the service's most important airlift platforms. More than 140 are still in active units, with more than 180 in the National Guard and a hundred more in the Reserve. The C-130 is powered by four turboprop engines.

The single-engine F-35A is the Air Force's eventual replacement for the F-16 and the A-10. The supersonic jets, which will be able to conduct air-to-air and air-to-ground attacks, are just beginning to enter the Air Force fleet.
