WASHINGTON — The Department of Defense must bolster its resilience in mission platforms in order to stay ahead of threats, a new think tank report says.
With the military's shift toward great power competition, or conflict against nation states, its systems and platforms will be under greater stress than technological inferior adversaries battled during the counterterrorism fight of the last decade-plus.
Systems and networks are expected to be contested, disrupted and even destroyed, meaning officials need to build redundancy and resilience in from the start to work through such challenges. In fact, top defense officials have been warning for several years that they are engaged in conflict that is taking place below the threshold of armed conflict in which adversaries are probing networks and systems daily for espionage or disruptive purposes.
“Resilience is a key challenge for combat mission systems in the defense community as a result of accumulating technical debt, outdated procurement frameworks, and a recurring failure to prioritize learning over compliance. The result is brittle technology systems and organizations strained to the point of compromising basic mission functions in the face of changing technology and evolving threats,” said a new report out today by the Atlantic Council titled “How Do You Fix a Flying Computer? Seeking Resilience in Software-Intensive Mission Systems.”
“Mission resilience must be a priority area of work for the defense community. Resilience offers a critical pathway to sustain the long-term utility of software-intensive mission systems, while avoiding organizational brittleness in technology use and resulting national security risks. The United States and its allies face an unprecedented defense landscape in the 2020s and beyond.”
This resilience, is built upon three pillars, the authors write: robustness, which is the ability of a system to negate the impact of disruption; responsiveness, which is the ability of a system to provide feedback and incorporate changes on a disruption, and; adaptability, which is the ability to a system to change itself to continue operating despite a disruption.
Systems, the report notes, are more than just the sum of its parts — hardware and software — but rather are much broader to include people, organizational processes and technologies.
To date, DoD has struggled to manage complexity and develop robust and reliable mission systems, even in a relatively benign environment, the report bluntly asserts, citing problems with the F-35′s Autonomic Logistics Information System (ALIS) as one key example.
“A conflict or more contested environment would only exacerbate these issues. The F-35 is not alone in a generation of combat systems so dependent on IT and software that failures in code are as critical as a malfunctioning munition or faulty engine — other examples include Navy ships and military satellites,” the authors write. “To ensure mission systems like the F-35 remain available, capable, and lethal in conflicts to come demands the United States and its allies prioritize the resilience of these systems. Not merely security against compromise, mission resilience is the ability of a mission system to prevent, respond to, and adapt to both anticipated and unanticipated disruptions, to optimize efficacy under uncertainty, and to maximize value over the long term. Adaptability is measured by the capacity to change — not only to modify lines of software code, but to overturn and replace the entire organization and the processes by which it performs the mission, if necessary. Any aspect that an organization cannot or will not change may turn out to be the weakest link, or at least a highly reliable target for an adversary.”
The report offers four principles that defense organizations can undertake to me more resilient in future conflicts against sophisticated adversaries:

By: Jen Judson ARLINGTON, Texas — The Bell V-280 Valor tiltrotor demonstrator flew autonomously for the first time Dec. 18 at the company's Arlington facility in two sorties. Over the course of the day, the V-280 met all of Bell's flight goals for the aircraft's first venture into flying autonomously. The V-280 performed an autonomous takeoff, conversion into cruise mode, precision navigation to various waypoints, loiter maneuvers, conversion into vertical takeoff and landing mode and also landed autonomously, Ryan Ehinger, Bell's program manager for the V-280, told reporters at a company demonstration of the aircraft in Arlington on January 8. Army Secretary Ryan McCarthy and Rep. Kay Granger (R-Texas) attended the demonstration. While safety pilots riding in the cockpit took over between different elements of autonomous flight throughout the sorties, the V-280 completed all pre-programmed elements “without issue,” Paul Wilson, the program's chief engineer, said. The company has yet to determine future flight tests as part of a continued effort to advance the tiltrotor's autonomous flight capabilities or whether it might specifically conduct a flight where all autonomous elements are stitched together without pilot intervention in between each maneuver. Bell developed its objective in late 2018 to run autonomous flight demonstrations with the V-280 and, just a year later, was able to execute the flight tests. The V-280 was built for the Army's Joint Multi-Role Technology Demonstration and had its maiden flight in December 2017. The autonomous flight took place on the second anniversary of the aircraft's first flight. The JMR-TD program is meant to inform the Army's Future Long-Range Assault Aircraft (FLRAA) program. A Sikorsky-Boeing team is also flying a demonstrator — the SB-1 Defiant — as part of the program but got off to a late start, flying for the first time in March 2019, mostly due to delays related to issues building the rotor blades for the coaxial helicopter. The Army is planning to modernize its fleet through an ambitious effort to acquire two new Future Vertical Lift (FVL) aircraft — FLRAA and a Future Attack Reconnaissance Aircraft (FARA) — back-to-back. The service intends to field FLRAA by FY30 following a full-and-open competition. The Army wants both FLRAA and FARA to be optionally piloted aircraft, but whether that capability comes in the first tranches when the fleet is fielded remain to be seen. Bell told reporters at the demonstration that since its first flight two years ago, the V-280 has logged over 160 flight hours among seven test pilots. It has demonstrated it can fly over 300 nautical miles in one trip and proven it can do 2G acceleration turns, can climb to 11,500 feet and has reached speeds of over 280 knots. The V-280 flew at 200 knots during the January 8 demonstration and performed other agility maneuvers while showing off its hover performance. While the JMR-TD phase is over, Bell continues to consider what could still be demonstrated with the V-280 before the aircraft is officially put to bed. https://www.defensenews.com/land/2020/01/09/bell-v-280-flies-autonomously-for-first-time

Dassault Aviation CEO Eric Trappier hinted at a new Rafale jet export contract in the making while speaking at his company's first half 2020 financial results conference in Paris earlier this week. “A potential new Rafale export contract is postponed,” he said while referring to the impact of the COVID-19 pandemic on Dassault's performance without naming the country with whom his company was close to signing the contract with. This is the first official acknowledgement by Dassault Aviation of a new Rafale export order reaching the contract stage- the first since deals were struck with Egypt, Qatar and India starting 2015. Reports of India being in talks to buy an additional 36 Rafale aircraft have been going on for a while now, but nothing has been revealed officially as yet. In addition, Dassault Aviation is in talks with UAE and Malaysia. It is in competition to sell jets to Switzerland and Finland pitted against European rivals Eurofighter and Saab. Of these prospects, India appears as the most likely candidate even as the first five Rafale jets arrive in India Monday. Earlier this year, comments by the Indian Chief of Defence Staff, Gen Bipin Rawat that a potential order for 114 jets would be “staggered” set off speculation of an additional order for Rafale fighters. A staggered purchase (of the Rafales) would ease financial burden by paying for the jets as they are manufactured. In addition, buying additional Rafales would ensure that the jets keep getting supplied to India uninterrupted beyond the end of the first contract for 36 jets. Several Indian media reports said that French aircraft manufacturer Dassault and India's HAL are in talks for possible cooperation in producing Rafale fighter jets in India for additional anticipated orders under a staggered procurement plan. The Economic Times reported in February this year that a few rounds of discussions have taken place between the two companies on possible work share for additional orders of the Rafale. In this context ‘work share' could mean local assembly of either the aircraft or some major components. It could also mean installation of some Indian components in the jet. Dassault and HAL are already implementing a contract to modernize India's Mirage-2000 jets. Additional Rafales could be cheaper than the 36 ordered in 2016 for Euro 7.8 billion. Of the total cost, Euro 195 million was spent on India-specific enhancements which will come down as the majority of the cost was for R & D, modification and certification. Besides, India had paid for setting up two bases for just 36 aircraft. These bases can easily accommodate more jets. https://www.defenseworld.net/news/27509#.XyCAdZ5KiUk
