Vertical lift drones brigades are assessing fly quieter with more survivability, soldiers say

Soldiers assessing aerial drones to help the Army replace its aging RQ-7 Shadow said the systems they've piloted can launch almost anywhere, offer a better chance of survival in combat against a peer adversary and have quieter motors that will prevent targets from detecting their presence.

“There have been times where the Shadow is too loud to fly too close to an enemy, so we can't get many details on them,” said Pfc. Jacob Owens, a drone operator at the 1st Infantry Division who has been testing Arcturus UAV's JUMP 20 at Fort Riley. “Quieter can be a huge advantage to us because we can get closer to get details on the camera, like read a license plate on the back of a car.”

Five brigades across the Army were selected to test unmanned aircraft systems and provide feedback to Army leadership looking to replace the RQ-7 Shadow, which was introduced in the mid-2000s. Owens and other soldiers spoke about the assessments they've participated in during a telephone call on Wednesday.

Information gleaned from the assessments will inform the Army's future vertical lift cross-functional team as they develop specifications for a a future tactical unmanned aircraft system, which is supposed to sport advances in maneuverability, agility, lethality and reach, according to Army Futures Command.

Futures Command began fielding the new drones to the five brigades across the force this spring, with 1st Infantry Division at Fort Riley, Kansas, receiving Arcturus UAV's JUMP 20 in mid-March.

JUMP 20 is the largest of the four drones being tested, weighing in at 210 pounds with an 18-foot wingspan, which is roughly similar to the Shadow.

The 17-hour flight time, vertical takeoff ability and reduced noise while in-flight will be a game-changer, said Sgt. 1st Class David Rodriguez, a platoon sergeant and standardization operator.

“Without the noise, it allows us to get closer to targets and identify them over longer periods without being identified by the sound of the motors as we fly overhead,” Rodriguez added.

The Army is looking for a Shadow replacement with reduced noise signature to retain the element of surprise and prevent targets from scattering if they see or hear the drone, noted the 1st Infantry Division Combat Aviation Brigade commander Col. Bryan Chivers, citing his experience in Afghanistan.

“You could have a Gray Eagle or Predator [drone] on station, observing a particular target, and when the Shadow would come on-station, you knew because somebody announced it and if you were privy to the operation, you could see them looking up to the sky and sometimes hearing this system,” Chivers said.

Vertical take-off is another specification the Army is seeking. It will allow launch and recovery at more locations, including austere ones without runways, and it should reduce the amount of equipment needed by soldiers.

Soldiers at the 101st Airborne Division at Fort Campbell, Kentucky, have been testing out Martin UAV's V-BAT. The V-BAT is unique in that it sits on its tail end during launches. It has a lot less equipment, soldiers said, but its flight time is roughly the same as the Shadow.

“We can pretty much operate it anywhere; We don't need a runway,” said Spc. Alexander Albritton, a drone operator at Fort Campbell.

A lot of the requirements the Army has put forth stemmed from an increasingly important operational need to be more “expeditious,” according to Maj. John Holcomb, the future tactical unmanned aircraft systems assistant product manager.

“One requirement we looked at for all the systems is the entire system could be loaded up on two Air Force 463L pallets and fit inside of a CH-47 [helicopter],” Holcomb said. “A Shadow system takes C-130s to get into theater and move around all the equipment that's required.”

These future drone systems will allow tactical commanders to not rely on airfields, noted Lt. Col. Brian Angell, a squadron commander at Fort Riley involved in the tests.

That could be important in a future fight against peer competitors like China and Russia that are able to pound stationary airfields and hangers with long-range weapons.

“It opens up options,” Angell said. “We'll be less predictable. We'll be able to maneuver this system on the battle space quicker, set it up, operate it and move it to another location faster. So that's a survivability standpoint, as well, that we'll gain with this system.”

A brigade at the 2nd Infantry Division on Joint Base Lewis McChord, Washington, began their own assessment of a third drone, Textron Systems' Aerosonde HQ, this week, according to Army Futures Command.

Later in the summer, the 1st Armored Division at Fort bliss, Texas, is scheduled to test L3 Harris' FVR-90 drone. Futures Command hopes to complete the fielding process with a brigade from the 82nd Airborne Division in September, when the paratroopers will test a second version of Arcturus UAV's JUMP 20 with different payloads.

The assessments will culminate with brigade-level combat training center rotations at Fort Polk, Louisiana, or Fort Irwin, California. Army officials have tentatively stated previously that the plan is to have the first unit equipped with a Shadow replacement sometime in fiscal year 2024.

    Done deal: Boeing will have to rip and replace KC-46 sensor and camera systems on its own dime

    By: Valerie Insinna WASHINGTON — Boeing and the Air Force have finalized an agreement to fix the KC-46 aerial refueling tanker's most serious technical problem, Defense News has learned from multiple sources familiar with the matter. The agreement puts an end to years of negotiations between the Air Force and aerospace giant over the nature and extent of redesign work needed to correct the Remote Vision System, the collection of cameras and sensors that provide boom operators the imagery needed to steer the boom into another aircraft and safely transfer fuel. Perhaps more importantly, the deal paves a path that will allow the service to deploy the KC-46 in combat in the mid 2020s — something Air Force leaders have bristled against with the tanker in its current form. The Air Force and Boeing have agreed on a two-phased roadmap to address RVS technical issues, said one source familiar with the agreement. The first phase allows Boeing to continue providing incremental improvements to software and hardware that will fine-tune the imagery seen by the boom operator, the source said. The second phase — which will take years to complete — involves a comprehensive redesign of the RVS where its hardware and software will be almost completely replaced with new color cameras, advanced displays and improved computing technology. Boeing and the Air Force both declined to comment on the matter. Unlike legacy tankers, where boom operators can look out a window in the back of the aircraft and rely on visual cues to steer the boom, operators in the KC-46 are completely dependent on the imagery provided by the RVS. Although Air Force operators say the system works in most conditions — and provides a safer way to offload fuel during nighttime conditions or bad weather — certain lighting conditions can cause the RVS imagery to appear warped and misleading, contributing to cases where the boom accidentally scrapes the surface of another aircraft. That could be a safety hazard for the pilot of the plane receiving gas, and it could also potentially scrape the stealth coating off a low observable jet, eroding its ability to evade radar detection. Under the terms of Boeing's fixed-price firm contract and previous agreements with the service, the company will be financially responsible for paying for the entirety of the redesign effort. The company has already exceeded the $4.9 billion ceiling on the contract, and has paid more than $3.5 billion in cost overruns as technical problems have mounted. Boeing is the system integrator for the RVS and designs its software, while the system's cameras and sensors are primarily designed by Collins Aerospace. Air Force's acquisition executive Will Roper is expected to brief congressional staff on the deal this afternoon, sources said. Afterwards, the service is expected to release additional information about the deal. Boeing delivered the first KC-46 tanker to McConnell Air Force Base, Kan., in January 2019, but the Air Force has withheld $28 million per aircraft upon delivery due to the RVS issues. So far, the company has delivered 33 tankers to the service. https://www.defensenews.com/breaking-news/2020/04/02/done-deal-boeing-will-have-to-rip-and-replace-kc-46-sensor-and-camera-systems-on-its-own-dime
