Top US Air Force general hopes for major KC-46 fix by March

By: Valerie Insinna

WASHINGTON — After more than a year of deliberations, the U.S. Air Force is hoping to have a fix in hand for the KC-46 tanker's most critical technical problem by the end of March, the service's top general told Defense News in an exclusive interview.

The hope is for the Air Force and Boeing to sign off next month on a finalized design for the KC-46's Remote Vision System, or RVS — a series of cameras and sensors that allow its users to steer the aircraft's boom into a plane for aerial refueling.

“The fact [is] that we're in negotiations right now; I can't say anything that would affect those negotiations,” Air Force Chief of Staff Gen. Dave Goldfein said in a Feb. 18 interview.

“Here's what I will tell you: They're not stagnant in any way, shape or form. It's a very active dialogue. We're working on getting a serious fix,” he said. “We're looking for a serious fix on the table by the end of March, and we're going to be flying that fix and starting to test it by the end of this summer.”

For several years, the KC-46 program has grappled with a critical deficiency involving the RVS, which is manufactured by Rockwell Collins. Under certain lighting conditions, the imagery is difficult to see and sometimes distorted, making it difficult for operators to safely move the boom without scraping the aircraft receiving fuel.

Despite ongoing RVS problems, the service and Boeing came to a compromise in late 2018 that would allow the aerospace firm to begin delivering the KC-46 if the company would swallow the cost of fixing the system to the Air Force's specifications.

At the time, Boeing and the service agreed on nine performance areas where the Air Force wanted to see improvements, but the parties have been embroiled in debate for months over how to turn those into technical requirements that would allow Boeing engineers to make specific hardware and software changes to the RVS design.

The first tanker was delivered in January 2019, but months later in September, Air Mobility Command head Gen. Maryanne Miller said Boeing had made no progress on the RVS and that it would take three to four years before the KC-46 was technically mature enough to deploy.

Tensions culminated in January 2020 when Goldfein sent a letter to incoming Boeing CEO Dave Calhoun criticizing the company for “unsatisfactory” progress on the RVS despite having a year to make design changes.

“We require your attention and improved focus on the KC-46,” Goldfein wrote in the Jan. 9 letter, which was first obtained by Bloomberg News. “The Air Force continues to accept deliveries of a tanker incapable of performing its primary operational mission.”

Calhoun came to the Pentagon for a face-to-face meeting with Goldfein on Jan. 15. According to Goldfein, the meeting went well.

“[Calhoun] committed to me in the meeting that the KC-46 was his top priority and he was going to put the talent, the resources and whatever the company needed to do to get it on track, so now I'm holding him to his word,” Goldfein said.

“I don't want to go into too many details because we're in a pretty intense negotiation, but I've seen a behavior change,” he added. Goldfein declined to provide examples of specific improvements but said he had seen “a different level of intensity from the leadership at Boeing on getting a serious fix for the KC-46.”

In a statement to Defense News, Boeing said it valued its partnership with the Air Force and is committed to delivering a KC-46 that matches the service's expectations.

“We're engaged in productive discussions with the Air Force about enhancements for the KC-46 Remote Vision System. We expect those discussions will establish a collaborative plan through which we can improve the aircraft's already robust capabilities,” the company said.

Having a finalized RVS fix on the books could be crucial for defending the Air Force's fiscal 2021 budget. The service plans to retire 13 KC-135 and 16 KC-10 tankers in FY21, but Congress has been skeptical of making reductions to the Air Force tanker fleet when demand continues to outpace supply.

An agreed-upon fix could also bring some financial relief for Boeing.

The Air Force is currently withholding $28 million per aircraft upon delivery of each tanker with the hopes of inducing Boeing to arrive at an RVS fix sooner rather than later. However, officials have said the service would be open to rolling back the amount of money the service withholds if it sees progress.

According to the terms of Boeing's fixed-price contract for the KC-46 program, the company is responsible for all costs past the award's $4.9 billion ceiling. Boeing has already eaten more than $3 billion in cost overruns, and the final price of the RVS redesign is still unknown and will likely trigger further penalties.

So far, 31 KC-46s out of the 179 planned for purchase have been delivered to the service. The Air Force indicated in 2019 that it would take three to four years to develop a fully functioning RVS.

    Countering missile threats means addressing the present while planning for the future

    By: Ian Williams In 2017, I helped author the CSIS report “Missile Defense 2020,” a broad look at the history, status and future of the U.S. homeland missile defense system known as Ground-based Midcourse Defense. The report argued that the establishment of GMD had put the United States in an advantageous position relative to the North Korean missile threat, but this advantage would be short-lived if the United States failed to improve GMD through incremental milestones and regular testing. GMD has had some notable achievements with this strategy. The Pentagon, however, seems to be moving away from this proven approach to GMD, attempting great leaps rather than manageable steps. This riskier approach could make the United States less secure over the near and long term. Until recently, GMD had been following a well-defined road map, with good results. After a series of flight-test failures from 2010-2013, the Missile Defense Agency began a rigorous effort to root out anomalies within the system's Ground-Based Interceptors, or GBI. MDA carried out a successful intercept in 2014, followed by intercepting an intercontinental ballistic missile-class target for the first time in 2017. In 2019, GMD engaged an ICBM target with a salvo of two GBIs, marking another first for the system. MDA also expanded the fleet to 44 GBIs and is constructing a new Long Range Discrimination Radar in Alaska to provide the system much-needed sensor support. These achievements were supposed to be followed by an incremental modernization of the GBIs. The plan was to incorporate a new Redesigned Kill Vehicle around the year 2020. The RKV would be similar in concept to those currently deployed but incorporate new technologies and nearly 20 years of lessons learned. Another part of the plan was to give the GBIs a new booster, one that gave the war fighter the option of using either two or three stages, thereby providing the system more time and space to engage incoming missiles. MDA also set its sights on a set of longer-term objectives. These goals included a space-based sensor layer for tracking missile threats, and a GBI equipped with multiple kill vehicles that would greatly expand the capacity of the GBI fleet. While the volume kill concept had great appeal, MDA recognized the need for a developmental step between the current kill vehicles and a more advanced, unproven concept. Historically, U.S. missile defense has done best when pursuing steady, achievable goals. The highly successful Aegis Ballistic Missile Defense program, for example, has consistently adhered to the mantra: “Build a little, test a little, learn a lot.” The RKV program, however, ran into delays. Yet, rather than continue trying to fix the program, the Pentagon opted to abandon it and skip directly to a more advanced, multi-kill vehicle approach called the Next Generation Interceptor. NGI is an ambitious, 10-plus year endeavor that carries significant risk. In the near term, it means that the president's goal to add 20 more GBIs to the fleet will go unmet, as those GBIs were supposed to be capped with RKVs. Any expansion to the GBI fleet before 2030 will require the design and construction of a modernized unitary kill vehicle of some kind. Absent any effort to expand or modernize the GBI fleet, homeland missile defense will likely fall behind the North Korean missile threat while NGI matures over the next 10 years. The decline will increase U.S. vulnerability to coercion by North Korean leader Kim Jong Un at a time when the U.S. military is scrambling to address Chinese and Russian aggression. Furthermore, a major delay of NGI a decade from now (or worse, a failure for NGI to materialize at all) would leave the United States with a fleet of GBIs falling rapidly into obsolescence, squandering decades of resources and effort. To be clear, the United States should continue developing NGI. Missile threats to the U.S. homeland continue to grow at an alarming pace, in quantity and complexity. But the Pentagon and Congress should support these longer-term efforts while still investing in nearer-term options that keep U.S. homeland defenses current to North Korean missile capabilities, hedge against NGI failure and preserve U.S. investments in the GMD system. A potential path forward may lie in the Senate's version of the fiscal 2021 National Defense Authorization Act, which contains draft language that would require the deployment of 20 additional GBIs equipped with an interim, unitary kill vehicle by 2026. Three years ago, we titled our study of GMD “Missile Defense 2020” because we believed that this year would be the start of a new chapter in U.S. homeland missile defense. Obviously, much has changed with the cancellation of RKV. Yet, despite all its challenges, this year may still provide the opportunity to make the kind of decisions that will strengthen our national security in the near and long term. https://www.defensenews.com/opinion/commentary/2020/06/24/countering-missile-threats-means-addressing-the-present-while-planning-for-the-future/

    Watchdog: 75 percent of sub and aircraft carrier maintenance ended late in recent years

    Geoff Ziezulewicz While the U.S. Navy has spent nearly $3 billion to improve shipyard maintenance performance in recent years, “the shipyards continue to face persistent and substantial maintenance delays that hinder the readiness of aircraft carriers and submarines,” according to a government watchdog report released this week. Three-quarters of the 51 aircraft carrier and submarine maintenance periods from fiscal 2015 to 2019 were completed late, resulting in 7,425 days of delays, according to the report by the Government Accountability Office. The Navy's four shipyards — in Portsmouth, Virginia; Kittery, Maine; Honolulu, Hawaii; and Bremerton, Washington — provide vital maintenance that includes ship overhauls, nuclear refueling, alterations and refits, among other duties. The aircraft carrier maintenance periods that ended late exceeded their deadlines by an average of 113 days, the GAO reports, while submarine maintenance periods ending late missed the mark by an average of 225 days. Such availabilities last anywhere from six months to three years, and when they don't end on time, it gums up the entire system, delaying other maintenance periods, deployments and other needs. The main factors leading to the tardiness had to do with shipyard workforce performance and having enough people to perform the vital work, the GAO found. Unplanned work, or tasks identified after finalizing maintenance plans, was also cited as a significant factor resulting in the delays. While the Navy has taken steps to address such delays, the sea service has yet to fully address the unplanned work and workforce factors causing the majority of delays, according to the GAO. https://www.navytimes.com/news/your-navy/2020/08/21/watchdog-75-percent-of-sub-and-aircraft-carrier-maintenance-ended-late-in-recent-years/

    Stop China’s predatory investments before the US becomes its next victim

    By: Jeffery A. Green An ancient Chinese stratagem instructs military leaders: “Chen huo da jie,” or “loot a house when it's on fire.” The tactic is simple and self-explanatory — strike when your enemy is most vulnerable. As America's people and industries reel from the impact of a global pandemic, the United States must take immediate action to protect our economic interests from being looted by a uniquely opportunistic adversary. Many U.S. companies have been substantially weakened in both market cap and revenue by the COVID-19 pandemic. With countless companies struggling to survive this crisis, the U.S. should institute a temporary but immediate and total ban on the sale of any U.S. company deemed “critical infrastructure,” whose value has been materially impacted by the pandemic, to a Chinese-owned or controlled entity. Until the president certifies that the economy has fully recovered from the effects of COVID-19, this ban should remain in effect. This crisis necessitates action far beyond the existing review process of the Committee on Foreign Investment in the United States. China's aggressive weaponization of its economy is no secret. Whether through currency manipulation or the withholding of critical materials, such as rare earth minerals, from the global supply chain, China has a reputation for using its economy in a targeted manner to further its ambitious global plans. Be it overtly or obliquely, through direct ownership or by de facto monopoly, China has encroached on or outright assaulted nearly every meaningful sector of the U.S. economy. There is ample evidence of China's exploitation and deception related to COVID-19. Credible reports are emerging that Beijing has taken donations of personal protective equipment and sold them to Italy and possibly other foreign countries. Further, the dubiously low official infection and death figures released by China are being juxtaposed with higher U.S. infection and death rates to enhance the narrative that China is the more competent nation and should therefore be regarded as the preeminent global leader. But China's infiltration and manipulation of the American economy and psyche began well before the COVID-19 crisis. From a national security perspective, Chinese companies have taken ownership of U.S. companies critical to the strategic supply chain, such as cutting-edge battery technologies and microelectronics. The U.S. is entirely dependent on China for segments of the supply of rare earth minerals, which are necessary for everything from cellphones to critical weapon systems. In 2013, a Chinese company purchased Smithfield Foods, simultaneously making the company the owner of both the largest pork producer globally and more than $500 million of American farmland. Beyond industries like defense and agriculture that form America's economic and national security backbone, China has opened new fronts to project soft power as well. The Chinese conglomerate Tencent began a 2015 push, as Tencent Pictures, into Hollywood with significant investments in major U.S. films, including quintessentially American films, such as “Wonder Woman” and “Top Gun: Maverick.” The Cold War era was rife with films juxtaposing an American hero and a Soviet enemy. With Chinese investment in the U.S. film industry and the growing importance of the Chinese market for these films, it's no coincidence there is a dearth of communist Chinese government villains in today's entertainment market. In 2004, China launched the Confucius Institute program, with the stated goal of promoting Chinese culture and language overseas. With mounting concerns about the spread of Chinese Communist Party propaganda through these institutes, as well as fears of possible espionage originating from them, universities across the world began canceling their affiliations. To date, more than two dozen U.S. universities have cut ties with these programs. While America seeks to recover from the economic impacts of this pandemic, Congress and the administration must take swift action to ensure China is not afforded any opportunity to enhance its economic foothold in the U.S. As distressed companies desperately look for funding and investment, the U.S. needs to send a message that financial exploitation by China will not be tolerated, especially if it involves companies working in industries critical to national security and our broader industrial base. As part of this infiltration of our business community, defense enterprise and culture, China will likely hire an army of lobbyists and lawyers to oppose this proposal. This, too, should be prohibited for the length of the economic crisis in the U.S. For millennia, Chinese dynasties have employed the tactic of looting a burning house as they vanquished enemies all around them. America must act before we become China's latest victim. https://www.defensenews.com/opinion/commentary/2020/04/17/stop-chinas-predatory-investments-before-the-us-becomes-its-next-victim/
