Steve Trimble July 07, 2020 The next combat aircraft to enter the U.S. Air Force inventory will not be a manned sixth-generation fighter or even the Northrop Grumman B-21. By fiscal 2023, the Air Force expects to deliver the first operational versions of a new unmanned aircraft system (UAS) called Skyborg, a provocative portmanteau blending the medium of flight with the contraction for a cybernetic organism. The Skyborg family of aircraft is expected to fill an emerging “attritable” category for combat aircraft that blurs the line between a reusable UAS and a single-use cruise missile. July 8 award date for Skyborg contracts Leidos is managing autonomy mission system As the aircraft are developed, Skyborg also will serve as the test case of a radical change in acquisition philosophy, with ecosystems of collaborative software coders and aircraft manufacturers replacing the traditional approach with a supply chain defined by a single prime contractor. The Air Force also plans to manage the Skyborg aircraft differently than other UAS. Although Air Combat Command (ACC) is considering the Skyborg family as a replacement for pre-Block F-16s after 2025 and MQ-9s after 2030, the aircraft is not likely to fit neatly into an existing force structure with dedicated Skyborg squadrons. “Even though we call Skyborg an attritable aircraft, I think we'll think of them more like reusable weapons,” says Will Roper, assistant secretary of the Air Force for acquisition, technology and logistics. The Skyborg is an attritable weapon, which means key components such as the jet engine will be designed with a short service life.

Starting in fiscal 2023, a concept of operations for a formation of four Lockheed Martin F-22s will include Skyborgs as part of the manned aircraft's load-out. “I expect that the pilots, depending on the mission, [will] decide: Does the Skyborg return and land with them and then go to fight another day, or is it the end of its life and it's going to go on a one-way mission?” Roper explains. In some cases, the pilot may decide a target is important enough that it is worth the loss of a Skyborg, even if its service life has not been used up, he adds. As the concept evolves, a diverse array of Skyborg aircraft designs will likely find roles beyond the air combat community, Roper says. “I don't think it'll just be fighters,” he says. “I think they'll fly with bombers. I think they'll fly with tankers to provide extra defensive capability. That's what I love about their versatility and the fact that we can take risks with them.” Skyborg is often presented as the epitome of the “loyal wingman” concept, in which one or multiple UAS are controlled or managed by a manned aircraft to perform a variety of surveillance, support and strike tasks during a mission. But the aircraft also could have the ability to operate independently of a manned aircraft, with the capability to launch and recover hundreds of such systems without the need for runways or even bases. The Kratos XQ-58A, which achieved first flight in March 2019, is one of several potential members of the Skyborg UAS family. Credit: U.S. Air Force “If [China and Russia] know that they have to target only tens or even hundreds of ports and airfields, we have simplified their problem,” says ACC chief Gen. Mike Holmes. The new class of attritable aircraft, he says, are designed so that “we can still provide relevant high-tempo combat power to be freed up from a runway.” If Skyborg is the future, it begins on July 8. The Air Force Research Laboratory (AFRL) is due on the second Wednesday of this month to award a contract to start developing the first in a family of experimental UAS bearing the name Skyborg. The AFRL already has a stable of potential concepts. The Kratos XQ-58A Valkyrie, which has flown four times since March 2019, is the most visible example of the AFRL's Low-Cost Attritable Aircraft Technology platform. Meanwhile, the Low-Cost Attritable Aircraft Platform--Sharing project quietly kept several UAS industry leaders involved in design studies, including Boeing, General Atomics Aeronautical Systems Inc., Lockheed Martin and Northrop Grumman. Each company selected will be awarded a contract with a maximum value of $400 million over a five-year ordering period. But the core of the Skyborg program is the software; specifically, the military aviation equivalent of the algorithm-fed convolutional neural networks that help driverless cars navigate on city streets. In announcing Leidos on May 18 as the Skyborg Design Agent (SDA), the AFRL selected the same company that delivered the software “brain” of the Navy's Sea Hunter unmanned surface vehicle, which navigated from San Diego to Honolulu in 2018. As SDA, Leidos' role is to deliver a software core that uses artificial intelligence to learn and adapt as the aircraft flies. The autonomy mission system core—as integrated by Leidos from a combination of industry and government sources—will be inserted into multiple low-cost UAS designed by different companies, with each configured to perform a different mission or set of missions. That is how the Skyborg program is set up today, but that is not how it started. Roper created the original “Skyborg” term and concept when he led the Strategic Capabilities Office within the Office of the Secretary of Defense in 2012-17. Roper transferred Skyborg to the AFRL, where it was renamed Avatar. A year after taking over Air Force acquisition in 2017, Roper changed the name back to Skyborg and created a program office in October 2018. In March 2019, Roper revealed the Skyborg concept to a group of reporters a week before the AFRL issued the first request for information to industry about the program. At that time, Skyborg was still organized more traditionally, with plans to select a single contractor to serve as a prime integrator. By early 2020, program officials reorganized Skyborg into modular hardware and software subcomponents built on an open architecture that requires no prime integrator. As the acquisition strategy has evolved, so has the Air Force's thinking about how to use the Skyborg family of systems. “The whole idea was [that] the contested environment is going to be challenging, it's going to be uncertain, and so it makes the most sense to have something that doesn't have a pilot in it to go into the battlefield first,” Roper says. “But once you agree that's a self-evident operational concept, it opens up the door for a lot of nontraditional thinking for the Air Force.” After a 2-3 year experimental phase, the AFRL plans to deliver an early operational capability in fiscal 2023. Follow-on operational Skyborgs could be funded within the Next-Generation Air Dominance (NGAD) project or through a separate program of record. The Skyborg concept even has links to the Air Force's architecture for the Advanced Battle-Management System (ABMS). “Attritable-ONE,” which is defined as having “multirole attritable capabilities,” is one of about 30 product lines in the ABMS architecture. “Skyborg and the AttritableONE teams are closely coordinated for planning and collaboration purposes,” the AFRL informed industry in response to questions about the Skyborg solicitation. The aircraft supplier must deliver a highly flexible design. Leidos, the design agent, will provide the autonomous mission system that will serve as the pilot, flight control computer and mission systems operator for the aircraft. But the “size, weight, power and cooling details for the Skyborg core autonomy system have not been finalized,” the AFRL told the bidding companies. “The majority of the system will be software-based and integrate with the sensors onboard the host aircraft,” the AFRL says. “Extensive collaboration between the Skyborg system design agent and the participants in this [contract] is expected.” https://aviationweek.com/ad-week/us-air-force-launches-three-year-fielding-plan-skyborg-weapons

By: Seth J. Frantzman JERUSALEM — An upgraded version of the Iron Dome air defense system has reached a “significant milestone” after contending with advanced threats in a test, Israel's Ministry of Defense announced Feb. 1. The Iron Dome is part of Israel's multilayered air defense and has been in service for a decade with more than 2,400 interceptions, mostly of projectiles launched from the Gaza Strip by militants. Two Iron Dome batteries were delivered to the U.S. Army in the last six months. “The Israel Missile Defense Organization (IMDO), in the Directorate for Defense R&D of the Israel Ministry of Defense, and Rafael Advanced Defense Systems have completed a successful series of flight tests of the Iron Dome weapon system,” Israel's Ministry of Defense said. “The Israeli Air Force (IAF) and Navy also participated in the test, which was conducted in a base in central Israel. The test campaign was held in a number of scenarios simulating advanced threats with which the Iron Dome is expected to contend during times of conflict — whether on land or in the sea.” The new system is expected to be delivered to the Israel Air Force for operational use — though it's unclear when — and then later installed on Israel's new Sa'ar 6 corvette, which arrived last year from Germany. It is expected to equip this new class of warships, which will be equipped with a variety of advanced Israeli systems in the coming years. The new ships are supposed to defend Israel's exclusive economic zone off the country's coast. Israel has expanded its infrastructure off the coast in the last several years due to natural gas discoveries in its exclusive economic zone, and the country signed a deal to build an Eastern Mediterranean pipeline to Greece via Cyprus last year. In the 2006 Lebanon war, the militant group Hezbollah fired a C-802 missile at a Sa'ar 5 ship. Egyptian and Saudi Arabian ships have also contended with anti-ship missile threats in recent years from Sinai and Yemen, respectively. Israel's Rafael would not elaborate on specifics of the test or the new capabilities. The ministry also would not provide further details beyond its statement. Video released by the ministry showed the logos of the companies involved, including the prime contractor Rafael; IAI, whose subsidiary Elta Systems is the maker of the multimission radar; and mPrest, which produces the BMC command-and-control system. The video also showed target drones launched over the water before Iron Dome intercepted them. It also showed several other quadcopter-style drones prior to takeoff, but it's unclear if they were targets in the drill. In mid-December, Israel launched an unprecedented integration test of its air defense systems, including Iron Dome, David's Sling and Arrow. During the test, Iron Dome was used to intercept cruise missiles — a new capability for the system. Drones and cruise missiles were used by Iran in September 2019 in an attack on Saudi Arabia, which led to concerns at the time over whether air defense systems were ready to confront drone swarm attacks or contend with slow and low-flying, maneuverable missiles. Iron Dome has received U.S. funding that tops about $500 million annually for joint air defense projects with Israel. In August 2020, Rafael and American firm Raytheon Technologies agreed to a joint venture to build Iron Dome in the United States. The facility builds the system and its Tamir interceptor, which is called SkyHunter, in the U.S. At the time, the system was said to be capable of intercepting cruise missiles, unmanned aircraft, rockets, artillery and mortars. When Israel completed the delivery of its second battery to the U.S. on Jan. 3, 2021, Israeli Defense Ministry Benny Gantz said he was “confident the system would assist the US Army in protecting American troops from ballistic and airborne threats as well as from developing threats in the areas where US troops are deployed on various missions.” Subsequent reports in Israeli media hinted that the U.S. might deploy the system to the Gulf where it has bases. Israel's MoD did not comment on the reports. The U.S. previously sent Patriot batteries as well as counter-rocket, artillery and mortar systems to defend against threats in the Gulf region. https://www.defensenews.com/training-sim/2021/02/02/israel-touts-upgraded-iron-dome-capabilities-against-land-maritime-threats
