Navy Turns To AI To Save Billions In Fight Against Rust

By

ALBUQUERQUE: The Navy is using Google Cloud to speed up a basic but time consuming task: finding and identifying rust. This approach has already been applied to inspect wind turbines and find potholes in roads, and promises advantages both in speed of inspection and in future predictive maintenance.

“The AI technology behind this enabled the US Navy to quickly and seamlessly examine tens of thousands of images to prioritize the needs to be repaired immediately and or later on,” Mike Daniels, vice president of Global Public Sector, Google Cloud, told me in an interview.

While Google was unwilling to disclose the exact value of the contract, the promise is that speedy, AI-enabled inspections will lower labor and material costs of inspection and repair enough to more than justify the expenditure on inspection AI.

“The tools we're providing can not only save the Navy billions each year, but significantly improve readiness and speed deployment,” said Daniels. “And this is a physical job right now. We're improving results for the inspectors.”

If AI-facilitated rust inspection can reduce the amount of time a ship needs to stay in harbor for repairs, it can narrow the window in which catastrophic disasters, like the fire which tore apart the Bonhomme Richard, can happen.

This work is being done through Simple Technology Solutions (STS), who was awarded the work as a Phase 1 Small Business Innovation Research project. To train the AI, STS flew a drone on inspections to get images of rust. Next, STS combined these drone-filmed images with public domain images of ships, and uploaded both sets to a Google Cloud server.

Specifically, the inspections will look for broad area rust and corrosion, as well as subtler damage that human eyes might skip over, like pitting or focused damage.

Using native machine learning built into the Google Cloud, STS could then train the algorithm to process, understand and identify rust in the images. This is an iterative process, one where every uploaded inspection improves the accuracy of the next inspection.

“There's no classified data that's going to be handled as part of this project,” said Daniels, noting that Google offers a high level of protection for images stored in its cloud by default.

As we have seen in the past, aggregated unclassified data can sometimes be enough to reveal classified information, but the immediate utility of cloud-powered inspections should offset any distant concern of weakness revealed through corrosion maintenance.

Most importantly, the inspection tool promises savings in time. A widely-cited 2014 report from the US Navy attributed the cost of fighting rust and corrosion at $3 billion.

Some of that cost is hard to shake: the paint used to cover rust-scrapped areas can cost as much as $250 a gallon. Catching corrosion quickly and early shortens the amount of time humans need to work to fix a vessel, and should reduce the area that needs repair for each inspection.

    Dassault Aviation receives order for 12 Rafales for French Air and Space Force

    Saint-Cloud, January 29, 2021 – Eric Trappier, Chairman and CEO of Dassault Aviation, today signed a contract for the sale of 12 Rafale aircraft with Florence Parly, French Minister of the Armed Forces. These aircraft will replace the 12 Rafales of the French Air and Space Force (FASF) sold to the Hellenic Air Force. The contract was signed during a visit by the French Minister of the Armed Forces to the Argonay plant in Haute-Savoie which has produced the flight control systems for all Dassault aircraft since 1963. Dassault Aviation and its industrial partners would like to thank the French Ministry of the Armed Forces, the French defense procurement agency DGA and the Armed Forces for their renewed confidence. “This contract for 12 new aircraft will enable our Air and Space Force to continue the Rafale build-up while awaiting the fifth tranche, which is scheduled for delivery between 2027 and 2030. The contract is a great satisfaction for Dassault Aviation, Thales, Safran and the 500 French companies involved in the program, in the particularly difficult conditions facing our aeronautics sector in the context of the Covid crisis“, said Eric Trappier. ABOUT THE RAFALE The only totally “omnirole” aircraft in the world, able to operate from a land base or an aircraft carrier, capable of carrying 1.5 times its weight in weapons and fuel, the Rafale has been designed to perform the full spectrum of combat aircraft missions: Interception and air-to-air combat using a 30-mm gun, Mica IR/EM missiles and Meteor missiles. Close air support (CAS) using a 30-mm gun, GBU laser-guided bombs and AASM GPS-guided bombs. Deep strike using Scalp/Storm Shadow cruise missiles. Maritime strike using the Exocet AM39 Block 2 missile and other air-to-surface weapons. Real-time tactical and strategic reconnaissance using the Areos pod. Buddy-buddy in-flight refueling. Nuclear deterrence using the ASMP-A missile. The Rafale entered service with the French Navy in 2004 and with the French Air and Space Force (FASF) in 2006, gradually replacing the seven types of previous-generation combat aircraft. It has been combat proven in different theaters: Afghanistan, Libya, Mali, Iraq and Syria. Of the 192 aircraft ordered by France to date, 152 have been delivered. A total of 114 Rafales have been ordered by Egypt, Qatar, India and Greece. ABOUT DASSAULT AVIATION With over 10,000 military and civil aircraft (including 2,500 Falcons) delivered in more than 90 countries over the last century, Dassault Aviation has built up expertise recognized worldwide in the design, development, sale and support of all types of aircraft, ranging from the Rafale fighter, to the high-end Falcon family of business jets, military drones and space systems. In 2019, Dassault Aviation reported revenues of €7.3 billion. The company has 12,750 employees.

    US Air Force components partner on low code, no code pilot programs

    Andrew Eversden WASHINGTON — The 16th Air Force and an Air Force cyber software development unit are partnering together on a “low-code, no-code” pilot program that will allow airmen with minimal training to develop software applications they need. Right now, the DoD is working on developing personnel into expert level coders, but that's not an easily scalable solution, according to Col. William Waynick, director of the Air Force's CyberWorx program, an Air Force office that works with industry and academia to deliver new tools to meet user needs. Hence, the pilot program, called the “Other Airmen,” which aims to get airmen just the basic skills they need to get a job done. “So we're looking at technology out there that will allow anybody with minimal training to develop applications that they need,” Waynick said at C4ISRNET's CyberCon virtual event. “Now, they probably want to go into the complex applications like they would have software houses. But we do believe that a majority of applications out there that the users need can actually be taken care of by low-code, no-code.” Waynick said the team currently has 20 people from across the Air Force and Army working with five vendors on the project. The teams are currently working on applications for equipment tracking, and readiness and training trackers. Another team is working on a contracting pilot to make it easier for industry to submit pitches to acquisition professionals. “They're interested in making an application for pitch decks from industry,” Waynick said. “So industry can, instead of just sending a white paper to an acquisition office, they can actually send the entire pitch. And so that way, they have video, and they can do maybe some Q and A's maybe live, but they're making an application to to provide a capability for industry to provide pitches as well.” The airmen and soldiers working on the project participate on the side of their normal jobs, including piloting, logistics or finance. In March, Waynick said that the team will brief Lt. Gen. Timothy Haugh, commander of the 16th Air Force, on the results of the pilot. CyberWorx is centered on delivering tool the user can actually us, not focusing on the technology for technology's sake, Waynick said. Airmen have an abundance of tools to choose from, he said, but the tools don't always do what the airmen need them to do. “The issue that I've seen, and I'm seeing still, is that there are too many tools. And I would just say, you know, each has a specific function,” Waynick said. “But not everything that the user needs so they have to go to another tool. And a lot of the times these tools aren't exactly what the user needs.” https://www.c4isrnet.com/show-reporter/cybercon/2020/10/29/us-air-force-components-partner-on-low-code-no-code-pilot-programs/
