Valkyrie

The Air Force Research Laboratory (AFRL), along with partner Kratos Defense & Security Solutions, Inc., completed the successful fourth flight test of the XQ-58A Valkyrie low-cost Unmanned Air Vehicle (UAV) demonstrator January 23, 2020, at Yuma Proving Ground, Arizona.

During the test event, the Valkyrie demonstrator’s flight successfully met all of the test objectives, and the envelope was expanded beyond prior tests before safely landing in the Arizona desert. According to AFRL XQ-58A Valkyrie Program Manager Michael Wipperman, flying at higher altitude allowed researchers to gather data in an operational environment more representative of real-world flight conditions.

«Flying at this altitude helped us gather important data such as vehicle response to temperature and vibration, which will prepare us as we move toward our next flight test», said Wipperman.

This test event represents a return-to-flight for the XQ-58A Valkyrie, which experienced a mishap upon landing after a successful 90-minute flight in October 2019. Following a Safety Investigation Board probe into the mishap, Wipperman says the resulting information was outbriefed to the convening authority, and the recommendations were taken and approved to ensure the success of this latest test.

«We’re very pleased with the outcome of this fourth flight test», said Wipperman. «We were able to show recovery for a successful flight at even higher altitudes. Given that we have overcome these challenges, we have confidence that the aircraft can continue its progression into flying in more representative conditions».

Developed as part of AFRL’s Low Cost Attritable Aircraft Technology portfolio, the XQ-58A Valkyrie is designed to be a runway-independent, reusable unmanned air vehicle capable of a broad range of operational missions. The XQ-58A Valkyrie was developed through low cost procurement and is designed to be significantly less expensive to operate than traditional piloted or unpiloted vehicles, while capable of achieving the same critical missions. Taking only 2.5 years from contract award to first flight, it is the first example of a class of unmanned air vehicles developed through this time-saving process, which seeks to break the escalating cost trajectory of tactically relevant aircraft.

A total of five flights are planned for the XQ-58A Valkyrie, with objectives that include evaluating system functionality, aerodynamic performance, and launch and recovery systems. The fifth flight, scheduled for later this year, will be a capability demonstration showcasing the ability of the vehicle to support operational needs.

Multi-Band,
Multi-Mission

Lockheed Martin, Ball Aerospace, and Kratos Defense & Security Solutions, Inc. were awarded a $7.2 million prototype agreement by the Defense Innovation Unit to develop a new Multi-Band, Multi-Mission (MBMM) prototype phased array as part of a broader initiative to modernize the existing Air Force Satellite Control Network and bring new technology faster to warfighters. MBMM enables multiple satellites to simultaneously connect with a single array antenna over multiple frequencies, a significant performance improvement compared to traditional single contact parabolic dishes.

The Lockheed Martin team is building prototype transmit and receive Electronically Steerable Arrays (ESA). Each array uses Ball’s advanced phased array technologies and supports L- and S-band frequencies initially. Signal processing is accomplished with Kratos’ digital Intermediate Frequency (IF) technology and cloud-enabled quantumRadio.

«MBMM is a smarter way to quickly and affordably scale satellite transmission while lowering long-term maintenance costs for the Air Force», said Maria Demaree, vice president and general manager of Lockheed Martin Mission Solutions. «Today, when a parabolic antenna goes down, it can take days to repair; with MBMM, it will take hours and won’t take the entire site offline – that’s a tremendous advantage».

Extensive industry research comparing the costs of parabolic antennas to phased arrays over time show that while parabolic antennas have a lower upfront cost, they become much more expensive to maintain. Phased arrays avoid the mechanical maintenance and keyhole effects of parabolic antennas while providing graceful degradation and electronic agility in matching aperture performance to constellation demands.

«One electronically steered antenna can replace multiple dishes, enabling better performance, connectivity and affordability», said Rob Freedman, vice president and general manager, Tactical Solutions, Ball Aerospace.

«Software modems deployed in virtual machines gives MBMM an advantage because it is easy to scale signal processing on a much faster timeline than previously», said Frank Backes, senior vice president of Kratos Federal Space.

Future operational MBMM systems will offer new cyber resilience while reducing long-term sustainment costs for the Air Force. MBMM may eventually support multiple orbits from Low Earth Orbit (LEO) to Geosynchronous Equatorial Orbit (GEO) and can perform multiple missions at the same time, including Command & Control (C2), launch pad and ascent operations, radar and mission data transmission. The Lockheed Martin/Ball team is one of several teams building prototypes for the government.
