  Some F-35 suppliers are having trouble delivering parts on schedule, and Turkey’s departure could make that worse

  By: Valerie Insinna WASHINGTON — Lockheed Martin's F-35 Joint Strike Fighter is on the verge of full-rate production, with a decision slated for early 2021. But a congressional watchdog group is concerned that as the company ramps up F-35 production, its suppliers are falling behind. And those supply chain problems could get even worse as Turkish defense manufacturers are pushed out of the program, the Government Accountability Office said in a May 12 report. According to the GAO, the number of F-35 parts delivered late skyrocketed from less than 2,000 in August 2017 to upward of 10,000 in July 2019. The number of parts shortages per month also climbed from 875 in July 2018 to more than 8,000 in July 2019. More than 60 percent of that sum was concentrated among 20 suppliers, it said. “To mitigate late deliveries and parts shortages — and deliver more aircraft on time — the airframe contractor has utilized methods such as reconfiguring the assembly line and moving planned work between different stations along the assembly line,” the GAO said. “According to the program office, such steps can cause production to be less efficient, which, in turn, can increase the number of labor hours necessary to build each aircraft,” which then drives up cost, the GAO added. Those problems could be compounded by Turkey's expulsion from the F-35 program, which was announced last year after the country moved forward with buying the Russian S-400 air defense system. Although Turkey financially contributed to the development of the F-35 as a partner in the program, the U.S. Defense Department has maintained that Turkey cannot buy or operate the F-35 until it gives up the S-400. The Pentagon has also taken action to begin stripping Turkish industry from the aircraft's supply chain, a process that involves finding new companies to make 1,005 parts, some of which are sole-sourced by Turkish companies. Ellen Lord, the Pentagon's undersecretary for acquisition and sustainment, had hoped to stop contracting with Turkish suppliers by March 2020, but in January she said that some contracts would extend through the year, according to Defense One. While the Defense Department has found new suppliers to manufacture the parts currently made in Turkey, it is uncertain whether the price of those components will be more expensive. Furthermore, as of December 2019, the new production rates for 15 components were lagging behind that of the legacy Turkish producers. “According to program officials, some of these new parts suppliers will not be producing at the rate required until next year, as roughly 10 percent are new to the F-35 program,” the GAO said. “Airframe contractor representatives stated it would take over a year to stand up these new suppliers, with lead times dependent on several factors, such as part complexity, quantity, and the supplier's production maturity. In addition, these new suppliers are required to go through qualification and testing to ensure the design integrity for their parts.” The F-35 Joint Program Office disagreed with the GAO's recommendation to provide certain information to Congress ahead of the full-rate production decision, including an evaluation of production risks and a readiness assessment of the suppliers that are replacing Turkish companies. In its statement, the JPO said it is already providing an acceptable number of updates on the program's readiness for full-rate production. Hard times for the F-35's engine supplier Not all F-35 production trends reported by the GAO were bad for the aircraft. Since 2016, Lockheed has made progress in delivering a greater proportion of F-35s on schedule, with 117 of 134 F-35s delivered on time in 2019. However, one of the biggest subsystems of the F-35 — the F135 engine produced by Pratt & Whitney — drifted in the opposite direction, with a whopping 91 percent of engines delivered behind schedule. At one point in 2019, Pratt & Whitney stopped deliveries of the F135 for an unspecified period due to test failures, which also contributed to the reduction of on-time deliveries. According to the Defense Contracts Management Agency, “there have been 18 engine test failures in 2019, which is eight more than in 2018, each requiring disassembly and rework,” the GAO wrote. “To address this issue, the engine contractor has developed new tooling for the assembly line and has established a team to identify characteristics leading to the test failures. Plans are also in place for additional training for employees.” https://www.defensenews.com/air/2020/05/12/some-f-35-suppliers-are-having-trouble-delivering-parts-on-schedule-and-turkeys-departure-could-make-that-worse/

  Pentagon transition begins, with a COVID-19 twist

  By: Aaron Mehta WASHINGTON — Less than a day after the General Services Administration opened the doors for the landing team from the Biden-Harris campaign to arrive at the Pentagon, members have already had two conversations with current defense officials, with more to come. But while the Presidential Transition Act of 1963 lays out clear directives on how one administration helps usher in the next — it literally comes with a handbook on best practices — this transition, like so much else in 2020, may require some flexibility thanks to COVID-19. The GSA's move — which came after growing criticisms from Democrats who felt the agency was slow-rolling the start of the transition for political purposes — freed up funds, office space and, critically for the Pentagon transition, allowed the sharing of sensitive information with the incoming team. However, the transition is kicking off just as the Pentagon upped its level of COVID preparedness. As a result, maximum occupancy has dropped to 40 percent, with extra temperature checks. According to Washington Headquarters Services Director Thomas Muir, the agency transition director, that won't stop the transition, but it may require the team to rely more on video teleconferencing than previous groups. The incoming team “is willing and certainly able to abide by the COVID restrictions here in the Pentagon. They agreed with the protection measures we're doing for our families, our employees, ourselves, our colleagues, our comrades here in the Pentagon.” Muir said at a press conference Tuesday, adding that “Some will work in the building, some will be virtual.” Kash Patel, the newly installed chief of staff for newly installed Acting Secretary of Defense Christopher Miller, will be leading the transition for the current administration. But Muir will manage the day-to-day work, according to chief Pentagon spokesman Jonathan Rath Hoffman. “I spoke with the chief of staff today, and he is assured me that Tom here is the lead on this and that he is going to be working with Tom, and Tom is going to be the one working with the team today,” Hoffman said, adding that Patel's role is mainly “to be the touch point for the secretary, to ensure the secretary has insight into what's going on and to make sure the transition is successful.” Patel also reached out to transition lead Kathleen Hicks in order to share his contact information in case she had any questions. Muir said his team has been preparing for six months in case a transition was needed, and believes the current set up will allow the Biden-Harris team to work as safely as possible. Included in that setup: office space at the Pentagon that allows for social distancing, and which comes equipped with both secure and unsecure VTC capabilities. With the GSA certification, the FBI and Department of Justice can begin giving security clearances to the transition team, allowing access to classified information needed to give an up-to-date situation report to the president-elect and his advisers. Informing the transition is a group of “transition assistance coordinators,” largely general officers or senior executive service civilians, drawn from key offices around the military agencies, combatant commands, joint staff and OSD. That group, which meets weekly, will provide information as needed to the transition team and help set up interviews with key officials. Muir noted he expects daily conversations with the Biden-Harris group, adding “They're looking forward to participating in discussions in the Pentagon. I'm providing a small tour on Monday next week.” https://www.defensenews.com/smr/transition/2020/11/24/pentagon-transition-begins-with-a-covid-19-twist/
