UAVs for Everyone: Navy Deploys Small UAV to Ships

Seapower magazine reports U.S. Navy Deploying Newly Designated RQ-20B AeroVironment Puma AE:
The U.S. Navy has tested and deployed the AeroVironment RQ-20B Puma small

unmanned aircraft system (UAS) aboard a Flight I Arleigh Burke-class guided-missile destroyer, the company announced in an Aug. 11 release. Some of these exercises included the use of AeroVironment’s fully autonomous system to recover the aircraft aboard a ship. The U.S. Navy issued a report on Aug. 3 from the Arabian Gulf describing how Puma AE is also being utilized on Navy patrol craft.


Following completion of a Puma AE intelligence, surveillance and reconnaissance mission, the AeroVironment Precision Recovery System provides for the autonomous on-board recovery of the aircraft, without interrupting the ship’s operations. Because the Puma AE is also designed to land and float in water, operators can choose to recover it from the ocean, should mission requirements dictate.

The AeroVironment Precision Recovery System occupies a small footprint and can be managed and operated by members of a ship’s crew, as opposed to requiring external contractors. It is transported in tactical packaging that can be hand-carried aboard and readily transferred from one ship to another.

“Our Precision Recovery System expands the capability of Puma AE to support maritime operations,” Kirk Flittie, vice president and general manager of AeroVironment’s Unmanned Aircraft Systems business segment, said in the release. “This solution also builds on AeroVironment’s extensive operational experience with small UAS to provide the Navy with a low-cost, hand-launched capability optimized for contested environments. Puma AE’s ability to operate from a wide variety of surface vessels ensures rapid response reconnaissance capabilities that help our customers operate more safely and effectively and proceed with certainty.”
More info from the manufacturer:
The Puma AE (All Environment) is a small unmanned aircraft system (UAS) designed for land based and maritime operations. Capable of landing in the water or on land, the Puma AE empowers the operator with an operational flexibility never before available in the small UAS class.

The Puma AE is durable with a reinforced fuselage construction, man portable for ease of mobility and requires no auxiliary equipment for launch or recovery operations. The system is quiet to avoid detection and operates autonomously, providing persistent intelligence, surveillance, reconnaissance and targeting data (ISRT).

The Puma AE delivers 3.5+ hours of flight endurance, with versatile smart battery options to support diverse mission requirements. Its powerful propulsion system and aerodynamic design make it efficient and easy to launch, especially in high altitudes and hotter climates. A plug and play power adapter is provided for easy integration of future extended endurance options, such as, solar and fuel cell solutions.

It carries both an electro-optical (EO) and infrared (IR) camera plus illuminator on a lightweight mechanical gimbaled payload, allowing the operator to keep “eyes on target.” For increased payload capacity, an optional under wing Transit Bay is available for easy integration of 3rd party payloads such as communications relay, geo locations, or laser marker to meet the diverse needs of military or civilian applications.

The precision navigation system with secondary GPS provides greater positional accuracy and reliability of the Puma AE. The UAV is operated from AeroVironment’s battle proven ground control station (GCS) with a communications range of 15 km.

A 15km range seems short for ship ops. On the other hand . . . it might meet certain needs in other ops. As in this interesting bit from here:
The UK tested ISR packages compatible with the Puma AE on board the M80 Stiletto trials ship in November 2014 under Capability Demonstration 15-1.

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:

Drone Wars: Combined Manned, Unmanned Carrier Operations



Shouldn't be surprise, should it?

I mean, that was the plan - right? USS Theodore Roosevelt Conducts Combined Manned, Unmanned Operations:
“Today we showed that the X-47B could take off, land and fly in the carrier pattern with manned aircraft while maintaining normal flight deck operations. This is key for the future Carrier Air Wing.”

Capt. Beau Duarte
Program Manager, Navy’s Unmanned Carrier Aviation office
Wave of the future.

More:
The first series of manned/unmanned operations began Sunday morning when the ship launched an F/A-18 and an X-47B. After an eight-minute flight, the X-47B executed an arrested landing, folded its wings and taxied out of the landing area.

"How to Make the Navy Bigger, Sooner, Cheaper" -A Revisit to 2008

Recently I was asked to provide some thoughts for "Corvette Week" over at
Coastal Command Patrol Boat  (U.S. Navy photo by MC2 Joshua Scott)
 CIMSEC NextWar and came up with Cheaper Corvettes: COOP and STUFT like that, in which I suggested that if "payloads" are the key to the future then the "platform" end of some naval force could allow for a different approach to getting drones of various types out to sea and, even more importantly, out to where the action might be. There is a nice follow on Non-Traditional Drone Motherships by NavalDrones.


As some long-time reader may know, that CIMSEC post was not my first foray into trying to figure out a way to pay less to get more to meet a problem identified by former Navy Secretary Winter back in 2008. One of my efforts was to suggest an anti-piracy force on the cheap, How to Make the Navy Bigger, Sooner, Cheaper
Too much ocean, too many shorelines, too many needs, too few ships. What's a navy to do?
The high-speed experimental boat Stiletto

Secretary Winter wants analysis of the right ships to build and a more efficient process to build them. All of which is fine, but - there is a faster, cheaper path to get bigger, sooner at lower cost - putting hulls in the water while awaiting that analysis.

Here's my modest proposal:
  1. Take $250 million dollars and put it aside;
  2. Of that $250 million, use $100 million to buy or lease 50 to 100 offshore crew boats as currently used in the offshore oil industry (many of them are reaching the end of their expected useful life in the industry - you might be able to pick up some bargains).
  3. Invest $50 million in refurbishing the boats and in getting weapons for their decks. Turn them into "navalized" vessels. Make 22 knots the minimum acceptable speed.
  4. Do not try to make these low cost littoral combat ships into battleships for all conditions. Talk to the LCDRs who will be squadron commanders and the LTs who will be the commanding officers about what they would need to provide a presence, fight in a low threat environment against modestly armed pirates and the like, support occasional missions ashore and interdict drug smuggler semi-submersibles. Give them what they need in terms of state of the art comms using COTS (heck, load put a communication van on board if so that no time is wasted trying to rewire the little ships more than needed). Put in some comfortable berthing suited for the sea states in which these things (I call them Special Purpose Vessels or SPVs) will operate.
  5. Under no cirmcumstance should the total U.S. Navy investment in any single SPV exceed $2 million, excluding the cost of adding weapons systems (adding a M-1 Abrams, for example) and the personnel costs.
  6. Make the project a 12 month "emergency" - and kill the bureaucracy that would ordinarily take on this job - find a hard charging Captain, make him or her report directly to SecNav and tell them what the mission and the budget will be. Then get out of the way except for monthly status reports.
  7. Over the horizon radar system
  8. Find a group of O-3s who are ready for command and who can think for themselves and train the heck out of them by letting them go to sea in the type of ships that you are acquiring, let them learn from the masters of current offshore supply and crew vessels. Find some O-4s who can take hold of the idea of being a squadron commander of a 5 ship squadron and train them in mission like that being conducted by the Africa station.
  9. Borrow some Army Rangers or fleet Marines and train them in the ship boardings, small boat ops, shipboard firefighting and ship defense. Treat them like the Marines of old. Stress people skills appropriate for counter-terrorism work.
  10. Lease some ships to be used as "tenders" for the SPVs - small container ships on which the containers can be shops, supply warehouses, refrigerator units, etc. Bladders for fuel. Use the Arapaho concept to set up a flight deck for helo ops.
  11. Be generous with UAV assets - use the small "net recoverable" types.
  12. Don't limit the small boat assets to RHIBs. Experiment with M-ships, small go-fasts captured from drug dealers, whatever. The idea is to have boats that can operate in one sea state worse than the pirates, drug smugglers, etc.
  13. Falklands war - container ship landing deck
  14. Use the MIUW van concept for adding some sonar capability. TIS/VIS is a necessity.
Start with a couple of squadrons, tell your O-6 that you want them ready in 6 months for operational testing. Unleash the budget dollars. For op testing, send one squadron off to the coast of Somalia for anti-pirate work. Send the other off Iraq. Put those expensive great big cruisers and destroyers currently in the area to work doing blue water stuff.

Paint Coast Guard like stripe on the hull of the SPVs - but make it Navy blue. If the Coasties want to join in, give them a boat and paint the stripe orange. Make the SPVs highly visible. Nothing deters crime like a visible cop on the beat.
I have made some spelling corrections and other modifications from my original post - and would probably add "offshore Gulf of Guinea" as a training zone for the force.

Further, the rapid development of drones of various types opens up lots of new possibilities for using this on-the-cheap "influence squadrons" (with apologies to CAPT Hendrix) to try out new approaches to littoral operations or inshore work. As Admiral Harvey pointed out during his recent appearance on Midrats (starting about24:20), the littorals are a complex world and even non-state actors are in possession of weapons capable of striking out at ships off shore. If you read CDR Salamander's post on a training accident in which a target drone managed to smack into a cruiser The CHANCELLORSVILLE Shrug it is worth reading the comments of Steeljaw Scribe concerning the potential issues facing ships operating close to shore facing a high speed missile threat:
What the BQM did isn't trivial by a long stretch...but consider this - take a 6,000lb+ telephone pole that has been burning liquid fuel to push it to between Mach 2.5 - 3.0; even if the large HE/SAP warhead doesn't fuse and detonate imagine the damage it would cause if C-ville had been hit in the same spot. As for the "shootshootshootshoot" the reality is if you are relying on ownship sensors and kinetic kill, you won't get past the "Oh Shit.." preamble (do the math -- 60-70 nm @ Mach 2.5 - 3.0 and 100 ft or below. And let's just say there are multiple missiles inbound because only Hollywood TTP shoots missiles in a stream raid of 1. We are fast moving beyond the capabilities of chemical-based weaponry to address an extant near-hypersonic threat in the terminal kinetic realm. We absolutely must be there to address the hypersonic threat that will begin to manifest itself before the end of this decade. Fortunately we have folks working on a number of solutions -- but I fear for I also hear a lot of whistling past the graveyard, especially at certain pay grades/GS/SES levels. w/r, SJS
CDR S and I have discussed before the realities of the short reaction window available to ship drivers who operate in restricted waters. One possibility is to come up with technical fixes that allow you to move your force sufficiently offshore to create some breathing space and allow counter-battery fire to be employed. However, if you look at the realities of the world we live on, the areas we most need to operate in are not all in deep blue water with infinite sea room to operate in. Instead, they are mostly narrow seas in which stand-off capability may, in fact, take you out of the fight and moving into the restricted area exposes large ships to numerous threats.

As I note in the CIMSEC post, one benefit of the use of smaller, cheaper ships with lots of drones is the increase it causes in targeting to your opponent. Given that no one in the fight has an infinite number of bullets, forcing your opponent to have to make hard choices on what to shoot at can only be good thing.

Influence squadrons, indeed! More platforms, more payloads, less money. Win,win, win.

Cheapening the Discussion of Corvettes (ships not cars)

CIMSEC asked for it, and I gave it to them "Cheaper Corvettes: COOP and STUFT like that"
U.S. Navy test missile firing drone
It occurs to me that we need to take the thinking that developed the WWII escort aircraft carrier (CVE) and model it down to a ship that is a “drone” carrier (and by “drone” I mean unmanned vessels of any type- surface, subsurface and aerial) – like the LCS only in the smaller economy version.

After all, if the real weapons systems toted by the LCS are its drones, then virtually any vessel capable of lowering said drones into the water or into the air and hosting their command and control system can be a “drone carrier,” too. Such a ship becomes a “mother ship” for the drones.
Read the rest here.
