The Navy has to get software updates and patches to the fleet within days if it's going to win in the future, the Department of the Navy's acquisition boss said Sept. 25 at Modern Day Marine.
James Geurts, assistant secretary of the Navy for research, acquisition and development, said the fleet has been working on the rapid development of software to get needed upgrades to the ships ahead of pier-side availabilities, a pace he said was too slow for the modern battlefield.
“We recently did one of our proof-of-principles to say: ‘How do you take ... software, get it system certified, get it cyber certified then get it out over the airwaves, uploaded on to a ship and into the combat system in 24 hours,” Geurts said.
“My view is unless we get to the point where I can identify a software requirement, whether it's an [artificial intelligence] algorithm or something, find the solution, get it checked out on the network, give it whatever cyber-proofing it needs and get it into the fight in less than a week, we are not going to be successful in the long run.”
The Navy has increasingly found that its current systems are capable of adjusting to new threats through software upgrades rather than buying new systems and installing them, a time-consuming and cripplingly expensive process that has been the norm in years past.
Geurts said the Navy had to have a software architecture that was amenable to rapid upgrades so that developers would not need to re-test the underlying architecture each time a patch or fix is uploaded.
Furthermore, the service also has to develop cyber security standards that don't just weigh whether or not something can be compromised but begin to think of it more in terms of risks associated.
“The answer isn't yes or no, it's ‘Commander here is your risk.' And then weigh the risk of doing that [upgrade] versus a potential cyber impact so that commanders can make reasonable command decisions. Because there is always a risk to not doing something. We often talk about the risk of doing something, we don't often talk about the risk of not doing it.”
Geurts told a gaggle with reporters after the talk that he was not talking about uploading whole new programs that sailors might be unfamiliar with but more iterative upgrades.
"Don't take that to an extreme to where we will load on something that nobody has ever seen before, but it could be that there is a particular issue or new need, and you can envision us testing and training that shore-side, making sure it's right – we don't want to wait for the ship to come home we could potentially blast that out [to the fleet.]"
The Navy is also working more with having digital doppelgangers of its combat system on board its ships so that new technologies can be tested by the crew and commanders before its uploaded into the main combat system, a hedge against reaping unintended consequences by uploading a feature or patch without knowing exactly how it will fit into the ship's systems.
"The other thing we are doing a lot with is digital twins, where [the ship] might have the combat system that it's fighting with as well as a digital twin,” Geurts explained. “So you might be able to upload that new feature in the digital twin so you could have both, then it's up to the commander whether it's something you adopt or not.”

The Air Force is close to testing an experimental vertical takeoff prototype under its new program. The first contract in the U.S. Air Force's bid to acquire flying cars has gone to a company whose design harks back to a pioneer in the field. California-based Sabrewing Aircraft Company received a $3.25 million Phase II Small Business Innovative Research earlier this month to test its Rhaegal-B, a four-rotor craft that the company says can carry up to 5,400 pounds up to 200 knots some 1,000 nautical miles. With its four electric rotors, two on either side of the aircraft, the 60-foot Rhaegal-B somewhat resembles the M400X Skycar from Paul Moller. Moller is, in many ways, the Nikola Tesla of the flying car field. In the early 2000s, the Moller International Skycar became the first non-helicopter vertical takeoff and landing aircraft to actually get off the ground. The four motors would lift the car up and then swivel to propel it forward, like a V-22 Osprey. Even though the design worked, it never made it into showrooms. “For the engine, the most critical element is power,” Moller told The Futurist magazine in 2008. “Once you reduce the diameter of the propulsion system [making the propellor smaller] you go from a helicopter to a fan system. So you're moving less air, and the less air you move, the more power it takes to generate a certain kind of thrust. If I took a helicopter and made it one-half the diameter, I would have to immediately add 60% more power. I halve the diameter again, I have to add 60% more power, again. The M400 Skycar has over 1,000 horsepower.” Given the high cost to power it, the M400 Skycar was impractical for most locations outside of the Middle East, where oil sheiks would use them to traverse wide distances, Moller said at the time. Sabrewing CEO Ed De Reyes, who once worked for Moller, said his former boss was restricted by the engines of his time. The best-suited for the purpose were Wankel rotor engines, and internal combustion engines, which offered high speeds but limited torque. The electric motors that have arrived in recent years are far more promising: smaller, lighter, yet capable of producing more torque than an internal combustion engine. The Rhaegal-B design is highly but not fully autonomous, De Reyes said. A controller will command it from a ground station, but with the sort of low-effort, push-button interface you would encounter on a Northrop Grumman Global Hawk, rather than the more hands-on piloting needed for General Atomics MQ-9 Reapers. Something else that's come a long way since the early 2000s is the ability to detect and avoid objects in mid-air. Ssense-and-avoidance systems are a major stepping stone to more widespread use of drones in U.S. civilian airspace. A lot of drone manufacturers are hoping for the FAA's blessing for their versions. The Rhaegal-B combines radar and nine other sensors to give the aircraft a picture of the environment around it. It can take evasive action without any human control. (In fact, humans can't override it to accidentally steer the vehicle into something else.) If communication is cut off, it can continue to its destination with no additional imput from the ground operator. The appeal for the Air Force has to do with versatility and even detectability. During a webcast on Monday, Air Force Col. Pete White, with Air Force Warfighting Integrating Capability, said that traditional helicopters are noisy compared new vertical-lift aircraft. Thanks, in part, to the new electric motors. “Within feet of an enemy, they can't hear you,” He said that new, nimble electric air vehicles that could take off and land without a runway could help the military “maneuver around the battlefield at a pace that would be impossible today” The Air Force says it wants flying cars to evacuate wounded soldiers from the battlefield, among other missions. That means that they could be operating under fire. De Reyes says the military version of the aircraft has a Kevlar coating to protect it from small ballistics and can operate even when one of the motors is damaged. Air Force officials have also said that they are looking to fund and support U.S. flying-car companies, lest they migrate to China or accept lots of foreign investment. De Reyes says he's often approached by Chinese investors looking to gain a foothold in his company and other entrepreneurs in this space are as well. Sabrewing will test the Rhaegal-B at the Air Force's Edwards Air Force Base, hoping to meet safety requirements that will clear it for more military work and perhaps even commercial use. A June flight demonstration with its prototype has been postponed due to travel restrictions https://www.defenseone.com/technology/2020/04/flying-car-future-looks-flying-cars-past/164995
