Typhoon’s 'Digital Stealth' Can Evolve To Meet Changing Threat

Mark Hewer, Leonardo's v-p for the Integrated Mission Solutions Business Area, believes that the company's open/reprogrammable electronic warfare (EW) suite for the Typhoon represents what he calls “digital stealth.”

This will confer a high degree of survivability, even in a threat environment whose lethality is growing exponentially, with the emergence of a plethora of high-end, software reprogrammable, multi-spectral threats, including surface-to-air missile systems. These threat systems are being updated more regularly and are frequently networked, allowing them to share intelligence of the air situation.

EW systems are able to evolve to deal with this dynamic and rapidly changing threat, in a way that fifth-generation stealthy aircraft cannot. While stealth aircraft are hard to detect, they are not invisible, and counter-stealth technology is developing rapidly. Moreover, the skin, internal structure, and configuration of an aircraft cannot be easily altered. “You cannot easily modify a stealth platform to counter new high-end threats,” Hewer said.

Typhoon's EW capabilities are provided by Leonardo's Praetorian Defensive Aids Sub-System (DASS), which incorporates an onboard podded ECM system and off-board ECM, with a towed radar decoy, as well as missile approach, laser, and radar warning systems and a flare and countermeasures dispensing system.

These systems will soon be augmented by the new BriteCloud, an active, highly programmable Digital RF Memory (DRFM) decoy that will allow the Typhoon pilot to better counter the highest-end threats. BriteCloud will give a discriminatory capability that is not on any other platform, providing a world-leading expendable active decoy capability on the Typhoon that none of its rivals will have. The MoD's Desidermagazine has predicted that initial operational capability on Typhoon will be declared in late 2019.

Arguably more important than the performance of the individual hardware elements within Typhoon's DASS is their ability to be reprogrammed. “What is really important for the high-end customer buying Typhoon is that their EW system is highly programmable,” Hewer said. “There's no point in directing your ECM if it is going to be ineffective against a threat because you're not exploiting its vulnerabilities.”

The Typhoon's EW system is undergoing continuous evolution, with regular upgrades to the hardware and a spiral software development process, but the most important factor is getting the right threat intelligence or “mission data” into the system. This is used to interpret the information that the sensors receive, and drives the behavior of the EW system.

Mission success will often depend on having the most up-to-date data set to ensure relevance to the environment. This makes the rapidity of the upgrade cycle of paramount importance.

Leonardo believes that many customers want a sustainable sovereign mission data capability, and it can offer to provide this as a service or as a fully tailored sovereign solution. The company can help customers to set up a national EW database or an aircraft specific database and has a suite of software tools available to customers.

While F-35 naturally incorporates advanced EW systems, there is still a very heavy reliance on the U.S. for mission support, with a relatively cumbersome mission data cycle. Hewer believes that Typhoon is “many years more mature in its operational use of programming for EW.”

While Leonardo's emphasis is currently on highlighting its ability to produce robust and agile high-end sovereign mission data generation capabilities for customers, the company is already looking to the future. Greater automation and machine learning promise a solution to the increasing complexity of the threat environment, and the company is also looking at the potential for sharing information across platforms as well as the possibility of reprogramming an EW system in flight.

DoD Awards Contract To Break Its Security Clearance Logjam
By BARRY ROSENBERG Can artificial intelligence, machine learning, and agile development help clear the massive backlog? WASHINGTON: The Pentagon hopes that a newly announced $75 million, 24-month contract will clear up its chronically backlogged security clearance system. The plan: develop prototype software that uses artificial intelligence to analyze routine data instead of humans running laborious background checks, freeing investigators to concentrate on the genuinely critical cases. How big is the mess? Hundreds of thousands of would-be federal employees and defense contractors wait an average of 221 days for a Secret clearance and 534 days for a Top Secret clearance, according to the National Background Investigations Bureau. The clearance backlog makes a day in line at the DMV look fast. It's a problem that costs the government millions of dollars and, in many ways, wastes the talent of countless individuals who give up and seek employment elsewhere. “The bottom line is we need to get cleared people to work in their job faster; we're not doing that job well,” said Terry Carpenter, the Program Executive Officer for the National Background Investigation Service, part of the Defense Information Systems Agency (DISA). “Whether you're in an agency, the federal government, or an industry partner .... we need to make sure those companies and agencies can get those people to work because they have their clearance.” The DoD's Defense Security Service (DSS), which runs the clearance process, and DISA, which runs much of the military's networks, jointly awarded the contract to Perspecta Enterprise Solutions of Herndon, VA, using the Other Transaction Authority process to bypass much of the traditional acquisition bureaucracy. Perspecta was formed in 2018 through the merger of the public sector business of DXC Technology, Vencore, and KeyPoint Government Solutions. Over the next 24 months, Perspecta will create a prototype “architecture” that can be scaled up to a full-sized security-check system, with two main features: Data ingestion and analytics using techniques like machine learning and natural language processing, which are both subsets of artificial intelligence; and A “software factory” to develop new vetting capabilities as needed. This will employ a software methodology called DevSecOps (Development-Security-Operations) that quickly delivers functionality that is then constantly improved through user feedback, while injecting security into all interactive phases of development, so usable software is delivered in weeks instead of months or years. Software development will be guided by a framework known as SAFe, which is an online knowledge base made available by an organization called Scaled Agile. The “factory” will continually develop, test, secure, and deploy new software in a government-run cloud, using what's called continuous authority to operate so its products can be used immediately, without a laborious certification process. The new architecture is being designed to transform three mission areas in the clearance process: initiation, investigation, and adjudication. Explained Carpenter: “There are several activities around the initiation part. [For example], you're a new employee coming in or a transfer coming in from a different agency. The initiation process engages with the subject and collects their information in a standard form that feeds the process. Then there's the investigation process. Under the old process, a full investigative package was prepared, which took a lot of time and labor. That was handed over for adjudication to an appropriate business function with the credentials to do the adjudication, and they would make the decision on that clearance. “What we are looking at today is continuous vetting as a way to use data to minimize the amount of labor force that has to knock on doors to get information. The more we can get done with data, the more effective we are at delivering the capability of a clearance, the more confidence we have in it, and the less it costs.” Data analytics will also facilitate continuous vetting throughout the work life of cleared individuals to address possible insider threats. “With this data-driven model, we can get into a continuous evaluation model rather than the current model, which is periodic investigation that looks at somebody every 5 or 10 years,” said Patricia Stokes, director, Defense Vetting Service, DSS. “We can utilize technology available today to initiate processes and capabilities to (gather) information on a real-time basis (to determine) your need for access and your risk.” https://breakingdefense.com/2019/05/dod-awards-contract-to-break-its-security-clearance-logjam

Air Force Announces Newest Red Tail: ‘T-7A Red Hawk’
Official Designation For Boeing's T-X Trainer The Air Force's all-new advanced trainer aircraft, the T-X, has officially been named the T-7A Red Hawk. Acting Secretary of the Air Force Matthew Donovan made the announcement during his speech at the 2019 Air Force Association's Air, Space and Cyber Conference in National Harbor, Sept. 16. Donovan was joined on stage by one of the original Tuskegee Airmen, Col. Charles McGee, who flew more than 400 combat missions in World War II, Korea and Vietnam. Also seated in the audience were members of the East Coast Chapter of the Tuskegee Airmen. After a short video highlighting the aircraft's lineage, Donovan said, “ladies and gentlemen, I present to you the newest Red Tail!” A drape was then lifted to reveal a quarter-scale model of a T-7A Red Hawk painted in a distinct, red-tailed color scheme. “The name Red Hawk honors the legacy of Tuskegee Airmen and pays homage to their signature red-tailed aircraft from World War II,” Donovan said. “The name is also a tribute to the Curtiss P-40 Warhawk, an American fighter aircraft that first flew in 1938 and was flown by the 99th Fighter Squadron, the U.S. Army Air Forces' first African American fighter squadron.” The Tuskegee Airmen subsequently painted their Republic P-47 Thunderbolts and North American P-51 Mustangs with a red-tailed paint scheme. The T-7A Red Hawk, manufactured by Boeing, introduces capabilities that prepare pilots for fifth generation fighters, including high-G environment, information and sensor management, high angle of attack flight characteristics, night operations and transferable air-to-air and air-to-ground skills. “The T-7A will be the staple of a new generation of aircraft,” Donovan said. “The Red Hawk offers advanced capabilities for training tomorrow's pilots on data links, simulated radar, smart weapons, defensive management systems, as well as synthetic training capabilities.” Along with updated technology and performance capabilities, the T-7A will be accompanied by enhanced simulators and the ability to update system software faster and more seamlessly. The plane was also designed with maintainers in mind by utilizing easy-to-reach and open access panels. The T-7A features twin tails, slats and big leading-edge root extensions that provide deft handling at low speeds, allowing it to fly in a way that better approximates real world demands and is specifically designed to prepare pilots for fifth-generation aircraft. The aircraft's single engine generates nearly three times more thrust than the dual engines of the T-38C Talon which it is replacing. “The distance between the T-38 and an F-35 is night and day,” said Air Force Chief of Staff General David L. Goldfein. “But with the T-7A the distance is much, much smaller, and that's important because it means the pilots trained on it will be that much better, that much faster at a time when we must be able to train to the speed of the threat.” A $9.2 billion contract awarded to Boeing in September 2018 calls for 351 T-7A aircraft, 46 simulators and associated ground equipment to be delivered and installed, replacing Air Education and Training Command's 57-year-old fleet of T-38C Talons. The first T-7A aircraft and simulators are scheduled to arrive at Joint Base San Antonio-Randolph, Texas, in 2023. All undergraduate pilot training bases will eventually transition from the T-38C to the T-7A. Those bases include Columbus Air Force Base, Mississippi; Laughlin AFB and Sheppard AFB, Texas; and Vance AFB, Oklahoma. http://www.aero-news.net/index.cfm?do=main.textpost&id=ee428ce4-f656-4eb1-9167-ae750094f54f
