U.S. Naval Research Lab Good Stuff: Multiple Unmanned Air Systems Launched By U.S. Navy

New Unmanned Air System tested on USS Coronado

“Nomad, is a low-cost rotary wing vehicle in which researchers can test remote control, autonomous flight control, station keeping and safe coordinated flight supporting any number of possible future payloads,” says co-principal investigator Steve Tayman, senior aerospace engineer with NRL’s Vehicle Research Section (VRS). “The unique form factor provides compact, light-weight storage in an integrated launch tube, and allows for storage in a ready-to-use condition for quick reaction deployment.”

The Nomad is a highly affordable expendable design, allowing for execution of its mission without concerns for returning to the ship. This new upgrade retains the original affordable expendable design, but now has a recovery feature that allows operators to retrieve and reuse the Nomad vehicles multiple times in support of development, testing, training, and potentially future operational missions.
***
The system now has multi-launch capability, deploying multiple Nomads in quick succession instead of singularly, while retaining the system’s safe CO2 ejection system design. Tayman states that this creates an equally safe launching mechanism that can support a higher quantity of Nomads.

The Nomad test on Coronado marks the first time this multi-launch and retrieval technology has been tested on a U. S. Navy ship. “We’re excited to demonstrate this technology utilizing forward deployed fleet personnel and assets, testing one of our newest technologies on the Navy’s newest class of ships,” says co-principal investigator Aaron Kahn, a senior Guidance, Navigation, and Control researcher also with the VRS.

“During this test we were able to show multiple Nomads can safely operate in the same airspace and fly in a coordinated fashion. The ability to retrieve Nomads back onboard the ship opens up future opportunities for testing and fleet training with more expensive payloads – an aspect of affordability that can easily be overlooked” says Kahn.
But wait, there's more - how about a Nomad that flies to a location and then turns into a "swimmer?" Behold the "Flimmer" --




100+ mile range, several days or "weeks" of endurance, maybe.

A flying sensor that is expendable like a sonobouy.

Fun with Drones: Autonomous Undersea Vehicles Operating Cooperatively

The Ocean News headline understates the import of the exercise in Iver3-AUV Plays Active Role in Unmanned Warrior (UW) 2016
***
Multiple Iver AUVs were put in active roles by members of the Royal Navy, US Navy and the Defense Research and Development Canada (DRDC). The Iver-3 systems were used in a segment of Unmanned Warrior known as Hell Bay, during which groups of underwater vehicles demonstrate how they collaborate to carry out autonomous tasks like target location and recognition.

Several of the Iver3 AUVs were equipped with SeeByte Neptune, an open architecture enabling autonomous multivehicle collaboration. Designed to enhance Mine Counter-Measure (MCM) missions, the system offers launch and recovery software management, water column flight management, static and dynamic exclusion zones, survey and re-acquire tasks, and real-time progress and status monitoring. The Iver3 MCM systems come equipped with high resolution side-scan sonar, RDI Explorer DVL w/ADCP, WHOI Micro modem, Iridium Communications and an operator console.

The ON report is based on a Iver3-AUV manufacturer, OceanServer press release.

This is very cool stuff. Autonomous cooperation and deconfliction of the water space are vital for future ops.

More, please.

Gremlins? Really? Retrievable and Reuseable UAVs to Add to Air Mission Packages

DARPA has contracts out to explore unmanned air systems (UASs) that are air recoverable and reusable as set out in this news release "Gremlins Takes Flight to Provide Air-Recoverable Unmanned Air Systems":
DARPA has awarded Phase 1 contracts for its Gremlins program, which seeks to develop innovative technologies and systems enabling aircraft to launch volleys of low-cost, reusable unmanned air systems (UASs) and safely and reliably retrieve them in mid-air. Such systems, or “gremlins,” would be deployed with a mixture of mission payloads capable of generating a variety of effects in a distributed and coordinated manner, providing U.S. forces with improved operational flexibility at a lower cost than is possible with conventional, monolithic platforms.
***
Named for the imaginary, mischievous imps that became the good luck charms of many British pilots during World War II, the program envisions launching groups of UASs from existing large aircraft such as bombers or transport aircraft—as well as from fighters and other small, fixed-wing platforms—while those planes are out of range of adversary defenses. When the gremlins complete their mission, a C-130 transport aircraft would retrieve them in the air and carry them home, where ground crews would prepare them for their next use within 24 hours.

The gremlins’ expected lifetime of about 20 uses could provide significant cost advantages over expendable systems by reducing payload and airframe costs and by having lower mission and maintenance costs than conventional platforms, which are designed to operate for decades.
My impression of airborne gremlins was shaped by my youth and Bugs Bunny:

Well, it is the 21st Century: "Third-Gen Electric Laser Weapon Now Ready"

Not a prototype
Aviation Week report by Graham Warwick, General Atomics: Third-Gen Electric Laser Weapon Now Ready
The company has responded to an Office of Naval Research (ONR) solicitation for a 150-kw laser weapon suitable for installation on DDG-51-class destroyers to counter unmanned aircraft and small boats using only ship power and cooling.

Under ONR’s Solid-State Laser Technology Maturation program, the weapon is to be demonstrated in 2018 on the USS Paul Foster, a decommissioned Spruance-class destroyer that now serves as the U.S. Navy’s ship-defense test vessel at Port Hueneme in California.

GA-ASI has proposed its Gen 3 High-Energy Laser (HEL) system, which recently completed independent beam-quality and power testing for the U.S. government. The Gen 3 system is the third generation of electrically pumped laser using the architecture developed for Darpa’s Hellads program.
Some info from General Atomics:
DDG 51 with frickin' lasers
General Atomics Aeronautical Systems, Inc. (GA ASI), a leading manufacturer of Remotely Piloted Aircraft (RPA) systems, radars, and electro-optic and related mission systems solutions, today announced that an independent measurement team contracted by the U.S. Government has completed beam quality and power measurements of GA-ASI’s Gen 3 High Energy Laser System (HEL) using the Joint Technology Office (JTO) Government Diagnostic System (GDS).

“These measurements confirm the exceptional beam quality of the Gen 3 HEL, the next-generation leader in electrically-pumped lasers,” said Claudio Pereida, executive vice president, Mission Systems, GA-ASI.

The new laser represents the third generation of technology originally developed under the High Energy Liquid Laser Area Defense System (HELLADS, Gen 1) program. The Gen 3 Laser employs a number of upgrades resulting in improved beam quality, increased electrical to optical efficiency, and reduced size and weight. The recently certified Gen 3 laser assembly is very compact at only 1.3 x 0.4 x 0.5 meters. The system is powered by a compact Lithium-ion battery supply designed to demonstrate a deployable architecture for tactical platforms.

The Gen 3 HEL tested is a unit cell for the Tactical Laser Weapon Module (TLWM) currently under development. Featuring a flexible, deployable architecture, the TLWM is designed for use on land, sea, and airborne platforms and will be available in four versions at the 50, 75, 150, and 300 kilowatt laser output levels.

The GDS was employed by an independent measurement team to evaluate the beam quality of the Gen 3 system over a range of operating power and run time. According to JTO’s Jack Slater, “The system produced the best beam quality from a high energy laser that we have yet measured with the GDS. We were impressed to see that the beam quality remained constant with increasing output power and run-time.”

With run time limited only by the magazine depth of the battery system, beam quality was constant throughout the entire run at greater than 30 seconds. These measurements confirm that the exceptional beam quality of this new generation of electrically-pumped lasers is maintained above the 50 kilowatt level.
What's it mean? Try this "Tactical Laser Weapon Module Can Laserify Almost Anything" the title of an Evan Ackerman post at the IEEE Spectrum:
The thing in this picture (you have to follow the above link to see it) isn’t a photon torpedo. But, it’s close. It’s a photon cannon, currently under development by General Atomics. Small, versatile, and completely self-contained, it turns anything onto which you stick it into a powerful laser weapon. And at just two cubic meters in volume, you should have no trouble mounting it on the roof rack of your Volvo.
***
What we were able to find out about this thing is that it’s a laser weapon with output energies (that's output, not total power in the system) ranging from 75 kilowatts all the way up to 300 kilowatts. To put that in perspective, about a year ago we wrote about how Lockheed was using a portable fiber laser to shoot down rockets at a range of 1.5 kilometers using just 10 kilowatts of power. Suffice it to say, 300 kilowatts is rather a lot. The weight of the system is dependent on its output power and the number of shots you want, but General Atomics engineers say that they’ve gotten it down to just 4 kilograms per kilowatt.

New 3rd Generation Model Introduced in the Eagle1 Series

We are pleased to announce that a new, improved, model has been introduced into the Eagle1 family as the Generation 3 lead model.

In keeping with tradition, the new model was delivered while part of his design team (Generation 2) was deployed at sea.

All Generation 1 models are ecstatic with this first model of the Generation 3 series, and their "cooing" functions are being activated.

Both the Generation 2 co-designer/production chief and Gen 3 Mk1, Mod 0 are doing well.

UPDATE: And the real deal -

Confusion to the Foe: U.S. Drone Swarms

From the Office of Naval Research:



ONR News:
Office of Naval Research officials announced recent technology demonstrations of swarming UAVs — part of the Low-Cost UAV Swarming Technology (LOCUST) program ...

LOCUST can launch swarming UAVs to autonomously overwhelm an adversary. The deployment of UAV swarms will provide Sailors and Marines a decisive tactical advantage.
Way cool. Now we need some applied imagination to work on how to best use these things - and not to make it "doctrine" but allow for ad hoc uses based on ground realities.

Another cool reveal at the Sea-Air-Space gathering, MDUSV
MDUSV: ONR’s Medium Displacement Unmanned Surface Vehicle (MDUSV) program will be to autonomous surface vessels what LDUUV-INP will be to the undersea autonomous realm. The technology will be joined with an emerging new platform called the Antisubmarine Warfare Continuous Trail Unmanned Vessel (ACTUV), in partnership with the Defense Advanced Research Projects Agency. This joint, modular platform is designed for multimission capabilities and modular payload options — and will bring new advances in speed, endurance and sea-state capabilities. On display is a model of the future 130-foot long vessel. The project will include the use of ONR-sponsored autonomous technologies similar to those used in autonomous swarmboats.

And then there is the Large Displacement Unmanned Underwater Vehicle (LDUUV) INP, described in 2014 by the Director of Disruptive Naval Technologies:
Why LDUUV: Develop fully autonomous long endurance UUVs capable of 60+ days of operation in the littorals, extend and multiply the current Navy platform’s capability.
• Ability to extend the reach of the Navy into the denied areas
• Focus Areas: Endurance, Autonomy, Advanced Energy
• 5x –10x Current UUV Energy Density
• Open Architecture
• Open Ocean/Over the Horizon Operations
Why is LDUUV Hard:
• LDUUV operates in complex ocean environments near harbors, shore, and high surface traffic locations that change significantly over relatively short periods of time.
• Need to dramatically increase power and endurance from current capability.
• Need to mature autonomous systems to compete complex missions and remain navigationally safe without human intervention.
Solution Attributes:
• Development of advanced air independent UUV energy systems to provide months of operations
• Focus on technologies that enable full autonomy in a cluttered maritime environment
• Conduct pier to pier fully autonomous operations to demonstrate increased mission flexibility
Update: LDUUV releases part of a "payload" (USN image)
• Defined interfaces and standards to payload and autonomy capability
development
• Leverage technologies from Navy Enterprises
Approach:
• Two BAAs, one addressing Autonomy and Endurance (individually), the other addressing Advanced Energy
• Potential for synergy with other UUV energy initiatives
• Leverage legacy and developmental autonomy technologies
How's all this unmanned stuff supposed to work? There was vision put out in 2013 by the U.S. Department of Defense "Unmanned Integrated Systems Roadmap with this image:


A very good read at Naval Drones "Robot Ethics and Future War" by CAPT (ret) Wayne P. Hughes, Jr:
*** Lucas described a common concern in ethical debates about the use of unmanned aerial vehicles (UAVs, or when armed, UCAVs). He put due stress on the future of autonomous lethal platforms, in other words robots, and on the development of cyber weapons. These and other emerging technologies such as autonomous or unmanned underwater vehicles (AUVs or UUVs) carrying mines or torpedoes might render war itself less destructive and costly, raising concern that it would be easier to rationalize their employment in inter-state conflict. This would lower the threshold for going to war, which then might expand in unanticipated, unintended, and deadly ways.
Read it all.
