Stealthy UAS Unveiled For USAF Target, Loyal Wingman Needs
Steve Trimble
A small start-up company in California has unveiled a new proposal for a stealthy unmanned aircraft system (UAS) to offer the U.S. Air Force as a “fifth-generation” target drone or a low-cost attritable aircraft.
Tehachapi, California-based Sierra Technical Services, a company founded by previously retired Lockheed Martin Skunk Works engineers, unveiled the first photos of the completed Fifth Generation Aerial Target (5GAT) prototype after completing engine tests on the ground. A first flight of the 5GAT is scheduled in early 2020.
The name of the aircraft is derived from its origins as a prototype funded by the Defense Department's Director of Operational Test and Evaluation (DOT&E), says Roger Hayes, president and CEO of Sierra Technical Services.
Several years ago, DOT&E recognized an emerging gap for a new target drone that could fly as a surrogate for fifth-generation fighters emerging in Russia and China such as the Sukhoi Su-57 and AVIC Chengdu J-20. In 2017, DOT&E awarded Sierra Technical Services a $15.9 million contract to develop the 5GAT prototype, Hayes said.
The pace of assembly has been dictated by the availability of parts cannibalized from other military aircraft, such as the engines and metallic components from the Northrop T-38 trainer and F-5 fighter, as well as aileron actuators from the Boeing F/A-18, Hayes said. Sierra Technical Services supplemented its revenue as assembly continued by working on other programs, including supplying components for the Kratos XQ-58A Valkyrie.
As development continued, the Air Force started to develop interest in a fifth-generation target. The service has awarded Lockheed Martin a contract to develop the AIM-260 Joint Advanced Tactical Missile, which is being designed to counter the PL-15 missile fielded on China's J-20 fighter. The Air Force needs to test the AIM-260 and other missiles against a representative threat. Last May, the Air Force released a request for information for the Next Generation Aerial Target, which included a version that can replicate fifth-generation fighter attributes, such as a stealthy airframe with canted tails and serpentine inlet ducts.
The Air Force also is developing a concept to pair manned fighters such as the F-22 and F-35 with an unmanned partner, known sometimes as a Loyal Wingman. The Air Force Research Laboratory (AFRL) funded Kratos' XQ-58A, which completed a first flight in March.
AFRL also plans to demonstrate a UAS controlled by a “software brain” using artificial intelligence. This Skyborg program is sometimes considered a follow-on for the XQ-58A program, but Hayes said Sierra Technical Services could offer the 5GAT for the Skyborg contract.

This mobile comms unit has people talking
By: Mark Pomerleau The Army has a slew of ongoing efforts to modernize its tactical network, including a focus on a pilot unit that moves quickly through the world and spectrum to tailor critical communications systems support. The Expeditionary Signal Battalion-Enhanced (ESB-E) supports units that don't have organic comms capabilities. These could include military intelligence battalions, chemical battalions, engineering battalions or air defense artillery branches. The ESB-E can also augment regular Army units, as a renewed focus on great powers requires all units to be much more mobile and expeditionary. What that means for signal battalions is their gear will have to be easily carried and set up to enable them to maneuver with units in a rapid manner. “The Army's transitioned to focusing on data environment and near-peer threat. The need for those logistical tails and for the enablers to move rapidly has increased, which is part of the demand signal that has gotten us away from” the Warfighter Information Network-Tactical of the past, Maj. Jeff Forry, S-3 50th Expeditionary Signal Battalion, told C4ISRNET during a demo of Army network modernization efforts at Fort Myer June 18. Forry said they've provided much more modular and scalable capabilities than the Humvee-mounted, satellite transportable terminal-based capabilities of year's past. In March 2018, the Army authorized the beginning of the ESB-E pilot, which is intended to create more mobile and agile kits for signal brigades. As part of the pilot, three companies under the battalion have been outfitted with capabilities from three vendors. This includes basebands — made by DTech, PacStar and Klas — with accompanying Tampa Microwave or L3 satellite terminal dishes of varying diameter depending on the users the unit needs to accommodate. Overall, the battalion has packages to provide communications for a variety of users. “When I plan a mission, less than 20 users, I'd start looking at small [packages] ... when we start pulling 20 up to 48 I'm looking at medium, and then after that we'd either use multiple mediums or start looking at the [large] package,” Forry said. The modularity of the kits mean, in many cases, just adding more users merely involves just sliding a small router into the baseband and utilizing a slightly larger satellite terminal. This is easier than the old WIN-T way of doing things where teams needed to bring full transit cases to add more users and bandwidth. One user noted that the modularity of the kit allows teams to mix and match based on the requirement. For example, if they only need connectivity to the Pentagon's secret network, as opposed to the unclassified network, they only need to bring those services with them. During a recent event at Dugway Proving Grounds, members from the signal battalion supported a chemical brigade, which had to get in and out of affected areas very quickly. The team took a small package and was able to get communication up in less than 10 minutes. They were onsite for 20 minutes, packed up and moved to the next site. The Army is continuing to utilize training events, combat training center rotations and exercises such as Saber Guardian in Europe to evaluate systems within the pilot program and execute operational tests for the gear. “The different approach we took for this prototype that we're doing is we didn't go set off a dedicated unit to do an operational test,” Col. Greg Coile, project manager for tactical networks at Program Executive Office Command, Control, Communications-Tactical, said. “Their operational test is when they go to Saber Guardian, when they go do the operational support, that is how we're testing and ... we use that user feedback going forward.” Coile added that this ongoing experimentation also allows units to get more repetitions as opposed to the old way of doing things, where the unit would get the equipment two weeks ahead of an operational test at something like the Network Integration Evaluation. Now units get an entire year with the equipment, which means the value of feedback is much higher, Coile said. The capabilities for the ESB-E unit will be part of the Army's first delivery of capability in 2021 for its network modernization the service is calling capability set 2021. Coile said the pilot will run until September, after which the Army will begin to make decisions on down-selecting vendors and outfitting actual units with the kits. The plan is to have every unit have the same equipment, as opposed to three companies currently outfitted with different vendor equipment for the prototype. A battalion will be complete in 2019, Coile said, and they are funded for three more in 2020. Moreover, they'll buy more in late 2020 to early 2021 and field those three. In 2021 there is funding for another three units, but the Army leadership will have to make a decision on what units get that. https://www.c4isrnet.com/battlefield-tech/2019/06/19/this-mobile-comms-unit-has-people-talking/
