Design Gets Underway on DARPA’s ‘LongShot’ Drone

Feb. 8, 2021 | By Rachel S. Cohen

Development of a new breed of unmanned aircraft is now underway, as three major defense companies earned contracts to start designing a future system known as “LongShot.”

The LongShot program wants to create an unmanned weapons porter that can be shot from another plane before firing multiple air-to-air missiles itself, according to the Defense Advanced Research Projects Agency, which runs the effort.

DARPA announced Feb. 8 it has funded General Atomics, Lockheed Martin, and Northrop Grumman to start design work in the project's first phase, but did not disclose how much money is part of those contracts.

“The objective is to develop a novel [unmanned air vehicle] that can significantly extend engagement ranges, increase mission effectiveness, and reduce the risk to manned aircraft,” DARPA said in a release. “It is envisioned that LongShot will increase the survivability of manned platforms by allowing them to be at standoff ranges far away from enemy threats, while an air-launched LongShot UAV efficiently closes the gap to take more effective missile shots.”

The project first appeared in DARPA's fiscal 2021 budget request as a prospective addition to the Air Force and Navy's inventories. The budget called for a plane that uses “multi-mode propulsion” to tackle multiple airborne threats at once, Air Force Magazine previously reported.

The program called for $22 million in its first year.

“LongShot will explore new engagement concepts for multi-modal, multi-kill systems that can engage more than one target,” DARPA wrote. “LongShot can be deployed either externally from existing fighters or internally from existing bombers.”

Last year, the research agency suggested the aircraft could fly slowly toward its target at first to save fuel, then speed up once it gets close.

“This approach provides several key benefits,” DARPA said. “First, the weapon system will have a much-increased range over their legacy counterparts for transit to an engagement zone. Second, launching air-to-air missiles closer to the adversary increases energy in terminal flight, reduces reaction time, and increases probability of kill.”

The Pentagon hasn't said what weapons LongShot would carry, or how autonomous its software might be. On paper, LongShot appears similar to other efforts like the Air Force's previous Gray Wolf missile program, which looked to create a munition that could carry other weapons inside. That was discontinued in favor of the service's Golden Horde swarming bomb project.

Later in the LongShot program, DARPA said, the companies will fly a full-scale prototype that is “capable of controlled flight before, during, and after” it is fired. The agency did not immediately answer how long the initial design phase will last.

The fiscal 2021 budget also called for a new program entitled “Gunslinger,” a new air-launched missile armed with a gun that would be designed for Air Force and Navy missions. But that appears to have a murkier future than the LongShot.

“The Gunslinger program has yet to formally launch and, at this time, we have no information on when that may happen,” DARPA spokesman Jared Adams said in December.

3-D printer keeps F-35B flying during USS Wasp deployment
MARINE CORPS AIR STATION IWAKUNI, Japan — State-of-the-art parts fabrication is keeping America's most advanced stealth fighter in the air during its first deployment aboard the USS Wasp. When a plastic bumper for a landing-gear door wore out this month on an F-35B Lightning II embarked on the amphibious assault ship, a 3-D printer was used to whip up a new one. The Iwakuni-based jet from Fighter Attack Squadron 121 later flew successfully with the new part, a Marine statement said. Called “additive manufacturing,” the process from Naval Air Systems Command allowed the Marines of Combat Logistics Battalion 31 to create the new bumper and get it approved for use within days, the statement said. Otherwise, they would have had to replace the entire door assembly, which is expensive and time consuming. “While afloat, our motto is ‘fix it forward,'” Chief Warrant Officer 2 Daniel Rodriguez, CLB-31's maintenance officer, said in the statement. “3-D printing is a great tool to make that happen.” The Navy said parts created using the 3-D printer are only a temporary fix, but it kept the jet from being grounded while waiting for a replacement from the United States. Lt. Col Richard Rusnok, commander of VMFA-121, lauded the use of the new technology. “Although our supply personnel and logisticians do an outstanding job getting us parts, being able to rapidly make our own parts is a huge advantage as it cuts down our footprint thus making us more agile in a shipboard or expeditionary environment,” he said in the statement. Marine Sgt. Adrian Willis, a computer and telephone technician who created the bumper, said he was thrilled to be involved in the process. “I think 3-D printing is definitely the future — it's absolutely the direction the Marine Corps needs to be going,” he said in the statement. The printer has been used multiple times during the patrol, the Navy said, including to create a lens cap for a camera on a small, unmanned ground vehicle used by an explosive ordnance disposal team. Templates for the parts will be uploaded to a Marine Corps-wide 3-D printing database to make them accessible to other units. bolinger.james@stripes.com Twitter: @bolingerj2004 https://www.stripes.com/news/3-d-printer-keeps-f-35b-flying-during-uss-wasp-deployment-1.522987

Google Drops Out of Pentagon's $10 Billion Cloud Competition
By Naomi Nix Alphabet Inc.'s Google has decided not to compete for the Pentagon's cloud-computing contract valued at as much as $10 billion, saying the project may conflict with its corporate values. The project, known as the Joint Enterprise Defense Infrastructure cloud, or JEDI, involves transitioning massive amounts of Defense Department data to a commercially operated cloud system. Companies are due to submit bids for the contract, which could last as long as 10 years, on Oct. 12th. Google's announcement on Monday came just months after the company decided not to renew its contract with a Pentagon artificial intelligence program, after extensive protests from employees of the internet giant about working with the military. The company then released a set of principles designed to evaluate what kind of artificial intelligence projects it would pursue. “We are not bidding on the JEDI contract because first, we couldn't be assured that it would align with our AI Principles," a Google spokesman said in a statement. "And second, we determined that there were portions of the contract that were out of scope with our current government certifications.” The spokesman added that Google is “working to support the U.S. government with our cloud in many ways.” The Tech Workers Coalition, which advocates for giving employees a say in technology company decisions, said in a statement that Google's decision to withdraw from the cloud competition stemmed from “sustained” pressure from tech workers who “have significant power, and are increasingly willing to use it.” Read more: Google Won't Renew Pentagon AI Drone Deal After Staff Backlash Google is behind other technology companies such as Amazon.com Inc. and Microsoft Corp. in obtaining government cloud-security authorizations that depend on the sensitivity of data a service is hosting. The JEDI contract attracted widespread interest from technology companies struggling to catch up with Amazon in the burgeoning federal government market for cloud services. Final requirements for the project were released in July after a months-long lobbying campaign in Washington by tech companies including Microsoft, International Business Machines Corp. and Oracle Corp. that opposed the Pentagon's plans to choose just one winner for the project instead of splitting the contract among a number of providers. “Had the JEDI contract been open to multiple vendors, we would have submitted a compelling solution for portions of it,” the Google spokesman said. “Google Cloud believes that a multi-cloud approach is in the best interest of government agencies, because it allows them to choose the right cloud for the right workload.” In a report to Congress, the Defense Department said making multiple awards under current acquisition law would be a slow process that “could prevent DoD from rapidly delivering new capabilities and improved effectiveness to the warfighter that enterprise-level cloud computing can enable.” The department also said it expects “to maintain contracts with numerous cloud providers to access specialized capabilities not available under the JEDI Cloud contract.” — With assistance by Ben Brody, and Josh Eidelson https://www.bloomberg.com/news/articles/2018-10-08/google-drops-out-of-pentagon-s-10-billion-cloud-competition
