The XQ-58A Valkyrie demonstrator, a long-range, high subsonic unmanned air vehicle... This joint effort falls within the Air Force Research Laboratory’s Low Cost Attritable Aircraft Technology (LCAAT) portfolio, which has the objective to break the escalating cost trajectory of tactically relevant aircraft. The objectives of the LCAAT initiative include designing and building UAS faster by developing better design tools, and maturing and leveraging commercial manufacturing processes to reduce build time and cost.
Developed for runway independence, the aircraft behaved as expected and completed 76 minutes of flight time. The time to first flight took a little over 2.5 years from contract award. The XQ-58A has a total of five planned test flights in two phases with objectives that include evaluating system functionality, aerodynamic performance, and launch and recovery systems.
“XQ-58A is the first example of a class of UAV that is defined by low procurement and operating costs while providing game changing combat capability”

At the forefront of efforts in this area is the US Air Force Research Laboratory's (AFRL's) Low-Cost Attritable Aircraft Technology (LCAAT) effort, one element of which is the Low-Cost Attritable Strike UAS Demonstration (LCASD) programme.

In July 2016, the AFRL selected Kratos to deliver the LCASD programme. Under a cost share arrangement with the AFRL, the company is contributing USD33.5 million of its own funds over the 30-month period of performance, while the government is committing USD7.3 million: the pay-off for Kratos is that it will retain the intellectual property rights on the XQ-222 Valkyrie air vehicle design under development for the programme.
LCASD cost and capability goals set down by the AFRL include a unit acquisition cost of not more than USD3 million for the first unit up to 99 units, and USD2 million or less for 100 or greater volume purchases; a 1,500 n mile mission radius with a 500 lb (230 kg) payload; and an internal weapons bay sized to carry and deliver at least two GBU-39 Small Diameter Bombs.
...
The platform under development for LCASD is using a Williams turbofan engine - the J33 - that is typically used in business jets. "[However, that is] not to say that there won't be an opportunity at some point in the future to try and improve engine efficiencies and bring costs down by considering the engine and other subsystems as attritable and rethinking how we address the reliability of some of the subsystems," Baron noted.

Likewise, if a mission will require a high-end, very-expensive payload, then attritable aircraft will not likely be the best assets to use. "From the get go that has been one of the considerations … if you've got a 15 million-dollar payload you're not going to want to put it on a 2 million-dollar aircraft," Baron explained, adding, "We're not going to do a lot of the missions that require an exquisite payload. That being said, we are working very closely with our sensor directorate to start exploring what sensor constructs can be brought forward."

Although the LCASD stresses low cost, Kratos has taken measures to reduce radar cross-section (RCS) through the incorporation of V-tails, a high-mounted engine inlet duct, and twin internal weapon bays (the option also exists to mount weaponry on wing stations albeit accepting an increased RCS). Furthermore, while the company's BQM-167 and BGM-177 target drones use Microturbo TR 60-5 turbojet engines, the Valkyrie will be powered by an internally fitted Williams International WJ-33 turbofan.
According to data released by Kratos, the XQ-222 will be able to achieve a maximum speed of Mach 0.85 and a ceiling of 45,000 ft. The fuel-efficient WJ-33 engine is intended to enable the Valkyrie to deliver a range of up to 1,850 n miles.
Kratos in May 2017 stated that it was on schedule for an estimated second quarter 2018 maiden flight.

The Low Cost Attritable Aircraft Technology Program (LCAAT) is a research area that seeks to introduce an unmanned aerial vehicle system to support warfighters with a lower cost than traditional manned aircraft, while meeting capability requirements for support in contested areas. Lower productions costs associated with the LCAAT program will allow different classes of UAVs to augment manned weapon systems and have highly optimized roles for specific missions including weapons delivery, locating targets, or communications.
“The basic problem that we’re trying to work is to address the continued escalation of costs associated with exquisite aircraft systems and when we look to the future, that trend is not going to change,” said Bill Baron, from AFRL’s Aerospace Systems Directorate at Wright-Patterson Air Force Base, Ohio, and program manager for the LCAAT initiative.
According to Stanley, “Combining low cost attritable unmanned aircraft systems with autonomy will provide a game changing capability that transforms the way we build and buy and the way we fly and fight. The design, logistics, and operations philosophy of an attritable system with autonomy is revolutionary.”

Resulta que el EdA aún está pendiente de recibir útiles básicos para la operación del Predator. Hablamos de sólo 50.000 euros en elementos como focos, generadores eléctricos, pequeñas grúas y similar, pero de las tres ofertas una quedó fuera por incumplir documentalmente, y las otras dos tenían algunos elementos que incumplían lo requerido:

MOSCOW, March 11. /TASS/. The Russian Armed Forces will commission medium-range attack drones for the first time in 2019, Russian Defense Minister Sergei Shoigu stated on Monday during a session of the Russian State Duma (lower house of parliament) Defense Committee.
He noted that since 2012, 38 military units have been formed in the Russian army, equipped with over 2,000 military drones.
"Starting this year, we will be receiving medium-range attack and surveillance systems," the minister said.
Shoigu stressed that a breakthrough in drone aviation has provided new opportunities for reconnaissance and attack operations. "Thanks to drone laser illuminators, we have managed to give a second life to precision artillery weapon systems "Krasnopol", which had not been in demand before. As a result, we have decreased their expenditure - no more than two projectiles for one target - and increased their range," the minister explained.
