The Pentagon has established a "red team" to address considerable shortcomings with the F-35C, the carrier-based naval variant of the most expensive weapons project in history.

The F-35, subject to cost overruns and delays throughout its production, reached an initial state of military readiness with its Air Force and Marine variants in 2016, but the Navy's variant lags behind in part due to an issue with its nose gear during catapult-assisted takeoffs from aircraft carriers, Inside Defense uncovered on Wednesday.

Essentially the problem, detailed in a Navy report with data dating back to 2014, deals with rough takeoffs that hurt and disorient pilots at the critical moment when they're taking off from a carrier.

The Pentagon's red team found the problem was due to several factors central to the plane's design, and recommended several fixes that will take several months to several years to fully fix. The report states that long term actions to address the problem will not take place until 2019, at which point they'll take 12-36 months to implement.

Redesigns to the plane, as well as to carriers, may be necessary to fully address the problem.

A Pentagon deficiency report in 2015 stated that extreme movements in the cockpit during launch risked pilot health.

One hundred and five pilots completing catapult launches rated their level of pain or discomfort on a scale of one to five. Of the 105, 74 pilots reported "moderate" pain or a 3, 18 pilots reported "severe" pain or a 4, and one pilot reported "severe pain that persists" after launching from an aircraft carrier.

"The oscillations shake the pilot's head sufficiently to impair their ability to consistently read flight critical data, which poses a safety of flight risk," reads the report cited by Inside Defense.

This pain, more than a mere inconvenience, threatens the ability of pilots to read flight-critical data as they perform the complicated task of launching from a moving platform at sea. Exacerbating the problem, some pilots locked down their harnesses to avoid jostling around during the launch, but this makes it more difficult for the pilot to eject, should they need to.

At a roundtable discussion in December, F-35 Program Executive Officer Lt. Gen. Christopher Bogdan assured reporters that F-35C takeoff problems only occur when the planes takeoff with low weight load outs, saying " you don't see this problem at all" when the plane is more laden with ordnance or fuel.

A representative from Lockheed Martin told Business Insider that all the catapult launches they had monitored were successful.

The F-35C was the most expensive variant of the Joint Strike Fighter program for the most recent Low Rate Initial Production contract. The Navy currently operates aging F-18s, nine of which have crashed or majorly malfunctioned in the last six months of 2016. The Aviationist's David Cenciotti attributes this to the age of the planes.
