Faulty $5 Parts Cause 18-Month, $1 Billion Delay to Navy, Air Force Nuclear Upgrades
Defects found in a $5 electrical component will delay the Navy and Air Force nuclear warhead refurbishment program by 18 months and cost more than $1 billion to fix, a National Nuclear Security Administration official said during a congressional hearing Wednesday.
The faulty components are small commercially available capacitors that were to be used in upgrades to the Navy's W88 nuclear warheads. These weapons are deployed on the Trident II D5 submarine-launched ballistic missile systems. Similar capacitors are needed to upgrade the Air Force's B61-12 gravity bomb, Charles Verdon, deputy administrator for defense programs at the National Nuclear Security Administration, told members of the House Armed Services subcommittee on strategic forces during the unclassified portion of Wednesday's hearing.
When engineers evaluated available parts, they ran tests to determine if the off-the-shelf capacitors were compatible with the systems due for upgrades, Verdon said. Initial results suggested the components would work in the short-term.
“Early tests on the capacitors now in question and subsequent tests including component, major assembly and full-up integrated system flight tests demonstrated that these components meet requirement today. Industry best practices were used to stress the components beyond their design planned usage as a way to establish confidence that they will continue to work over the necessary lifetime of the warhead,” Verdon said. “During stress testing, a few of these commercially available capacitors did not meet the reliability requirements.”
The problem is, these parts used in the warhead upgrades must survive for decades, up to 30 years after production, Verdon said. However, the quality of each capacitor production lot varied, which led to the stress testing failure. Instead of using the capacitors and risking readiness in the future, Verdon said his agency decided to delay the upgrade work, initially scheduled to begin in December.
Replacement capacitors are being produced but will cost about $75 per unit, compared with the $5 per unit cost of the off-the-shelf capacitors that failed stress testing.
“The use of commercial-off-the-shelf electric components needs to be improved to reduce future COTS-related risk,” Verdon said.
The Navy is working with U.S. Strategic Command to understand how the 18-month delay will affect near-term deployments, Vice Adm. Johnny Wolfe, the director of strategic systems programs for the Navy, told the panel.
“Currently, today, based on what we're doing with STRATCOM, we will meet the requirements as we move forward,” Wolfe said.
The Navy and STRATCOM are developing a mitigation plan which includes is reevaluating how to turn around the submarine-based nuclear missile stockpile and how to schedule warheads for upgrades in the future, Wolfe said. More details on the Navy's plan to be discussed in a classified hearing.
“If you look at the age of these systems and the technology we're using, these are tough, tough issues to solve, and it's critical technology that we're learning as we modernize these,” Wolfe said.
Rep. Jim Cooper (D-Tenn.), chair of the strategic forces subcommittee, said he held the hearing because he wanted more information on what NNSA was doing to avoid more delays. He called the recapitalization “both necessary and hugely expensive” in his written opening statement.
“Maintaining Congress and the public's confidence in these programs, and their effective execution, is imperative,” he wrote.

Team Dedrone Wins USSOCOM ‘Game of Drones’ Competition
Dedrone announced that its team of Echodyne Corporation, Squarehead Technologies and Battelle, won first place at ThunderDrone's “Game of Drones” outdoor demonstration at Nellis Air Force Base and AFWERX enclave, June 18-20. Hosted by AFWERX, Team Dedrone bested five other teams in the last of three ThunderDrone rapid prototyping events focusing on countering small, unmanned aerial drones. Team Dedrone successfully demonstrated the capabilities of a layered detection, tracking, classification and mitigation solution that defends protected airspace against aerial drone threats. Initially 93 counter-drone technology companies formed teams and were narrowed down through a series of three rapid prototyping events. The Dedrone platform is a fully automatic counter-drone solution, designed to detect, classify and mitigate drone-based threats. Dedrone's software, DroneTracker, gathers intelligence from Dedrone's RF sensors, Echodyne's MESA radar and Squarehead Discovair acoustic sensor. Once DroneTracker makes a positive identification of a drone, Battelle's non-kinetic defense system, DroneDefender™, is automatically triggered to defeat the drone and eliminate the threat. The Dedrone platform combines hardware sensors and machine-learning software, providing early warning, classification of and mitigation against all drone threats. Based in San Francisco, Dedrone was founded in 2014. ThunderDrone is a U.S. Special Operations Command and SOFWERX initiative dedicated to drone prototyping, which focuses on exploring drone technologies through idea formation, testing and demonstrating efforts that are being conducted collaboratively with the Department of Defense's Strategic Capabilities Office. SOFWERX leads collaboration between special operations warfighters and select contributors from industry and academia on technology and innovation efforts to bring drones, tactical swarms and their associated data science applications to the special operations community. Team Dedrone Quotes: “Dedrone's open platform and architecture allows customers to combine the best in drone detection and mitigation technology, such as with RF sensors from Dedrone, radar from Echodyne, acoustic sensors from Squarehead, and jammers from Battelle,” shares Joerg Lamprecht, CEO and co-founder of Dedrone. “This multi-layered sensor platform ensures that all organizations, including those under USSOCOM, are provided complete airspace security that is safe from all drone threats.” “ThunderDrone provided us with our first opportunity to simultaneously engage against multiple UAVs with two DroneDefender V2 systems,” shares Alex Morrow, Technical Director of cUAS Programs at Battelle. “Battelle is pleased with another successful demonstration of our DroneDefender V2.” “Echodyne's compact solid-state radar repeatedly demonstrates an unparalleled combination of range, tracking accuracy and value in countering UAS threats,” notes Eben Frankenberg, Echodyne CEO. “We're pleased that our beam steering radar once again contributed its indispensable capabilities as part of the award-winning Team Dedrone solution.” “Discovair's directional acoustics add a near unspoofable layer of super hearing. The ability to deal with drones hinges on detection. In cluttered areas and up against any drone system, even passive ones – Discovair acoustic sensor has proven to shine,” shares Stig Nyvold, CEO of Squarehead Technology. “Discovair's importance as part in the systems of systems has once again been proved. We are very excited to be part of this team and look forward to the future.” https://www.uasvision.com/2018/06/26/team-dedrone-wins-ussocom-game-of-drones-competition/
