A Combined Air/Surface Search Radar for Boats

Saabs-Sea-Giraffe-small-boat-radar-debuts-in-USA-320x179

The illustration here appears to show the system on a Combat Boat 90 (CB90) which is only a 52 foot long boat. 

I don’t see an immediate need for this, but it is an interesting new type of radar sensor.

Naval Today reports Saab is offering, “…a 3D, active electronically scanned array (AESA) radar offering simultaneous surface and air surveillance capabilities,” and “…the entire system weighs less than 650 pounds (294 kilograms) in total, which makes it suitable for smaller patrol ships.”

Apparently they are thinking UAVs, “To combat the growing UAV (Unmanned Aerial Vehicle) threat, Sea Giraffe 1X features Saab’s Enhanced Low, Slow and Small (ELSS) surveillance function. This feature allows the radar system to detect and classify small, low-flying, slow-moving air targets.”

I suppose this might also be used to control small UAVs, putting them over surface targets of interest. The Coast Guard is looking at small UAVs.

Common (Unmanned Unit) Control System

It now seems obvious that Unmanned Systems (air and possibly surface and subsurface) will play a part in the Coast Guard’s future, but the service has been, perhaps understandably hesitant to commit to any particular system.

Because of the variety of proprietary systems, integrating the control systems into the organization of the controlling unit, particularly ships and aircraft, and then integrating the resulting information into a common operating picture has been problematic.

Eaglespeak reports, it looks like DOD, through the Office of Naval Research, is moving in the direction of a platform agnostic software application that will permit common hardware to control different unmanned system.

This might permit Coast Guard units which commonly control small unmanned aicraft (sUAS) to be quickly adapted to

  • Control a much more capable UAS.
  • Hunt for mines using unmanned surface (USV) or subsurface (UUV) systems.
  • Control optionally manned surface craft to search for smugglers or enhance asset protection.
  • Control UUVs towing acoustic arrays, searching for submarines.
  • Direct a USV equipped with AIS, lights, and signals into position to serve as a temporary aid-to-navigation.

 

 

New ISR Sensor

Australia's Maritime Safety Authority will induct new search and rescue aircraft in the near future, with enhanced capabilities. Four Bombardier Challenger 604 jet aircraft will enter service from August 2016 and onwards.

Navy Recognition reports installation of a new type of sensor on four Australian medium range search aircraft. (Looks a lot like an HU-25 doesn’t it? It is a contracted SAR resource.)

This new sensor, Sentient Vision’s Kestrel Maritime ViDAR (Visual Detection and Ranging), is apparently a computer aided visual recognition system intended to detect objects as small as people in the water. A claimed advantage over human lookouts is that system performance does not degrade due to fatigue like human observers.

Apparently this technology is being tested on Scan Eagle and Firescout Unmanned Air Systems too. It is claimed that the system improves the search function on these UAS as much at 80 times that of unaided Electro-Optic systems.

It was reportedly tested by the USCG  “in 2014 and managed to detect small targets at a distance of more than 20nm.” I tried to find out a little bit more about the Coast Guard test, and apparently it was associated with the experiments with an aerostat deployed from the Healey.

Anyone know if this system has a future in the USCG?

Unmanned SAR Assets

sUAS

MarineLink has a short post about a European effort to use networked Unmanned Air and Surface Vehicles (UAVs and USVs) to do SAR. I don’t find their particular scenario persuasive, but there probably are roles for these systems.

Unmanned systems have some potential advantages over Manned assets although they are unlikely to ever replace them.

  1. It may be possible to have UAVs more widely distributed than manned CG Air assets.
  2. UAVs operating from SAR stations might also be able to get into the air more quickly  than manned aircraft because they do not have to contend with other air traffic that may be operating on the field.
  3. At least for some applications they may be cheaper to operate.

Frankly, I had thought of unmanned systems as primarily Law Enforcement assets, but the Coast Guard is looking as the possibility of locating personnel in the water using small UAVs.

USVs:

I have a hard time visualizing a use for Unmanned Surface Vessels (USV), but perhaps there might be a benefit in dropping a USV to a distressed vessel or person(s)  in the water either from a fixed wing or a UAV.

UAVs might be used:

  1. For communications relay.
  2. To deliver medication or medical equipment.
  3. Small UAVs might be used to confirm the location of vessels in distress before other units arrive.
  4. To deliver pumps, communications equipment, or other even inflatable liferafts.

Any Other Ideas?

Any other potential uses?

Small Unmanned Aerial Systems (sUAS)

The Acquisitions Directorate reports that the Coast Guard is at least looking at small UAS (UAVs for us traditionalists).

“The demonstrations are part of the RDC’s Robotic Aircraft for Maritime Public Safety project, which aims to determine the risks, benefits and limitations of operating commercial off-the-shelf sUAS technology in conjunction with Coast Guard cutters other than the national security cutter.”

Tests of seven systems were conducted on USCGC Chock (WYTL 65602), a 65 foot tug, so you know the systems had to be small. In fact, I have radio controlled airplanes bigger than these. Still, hopefully these are smarter.

An interesting aspect of the trials is that it included test specifically intended to determine if the sUAS would be useful in finding a person in the water. To do this they used a dummy with an enhanced IR signature comparable to that of a person they refer to as a “thermal Oscar.”

While UAVs of this size may have uses, ultimately, I think they will find that the system we need will be something with a radar that will fit on a Webber class, that means something similar to Scan Eagle. Smaller vessels don’t actually need their own UAS, they can be supported by UAS from ashore. Perhaps every SAR station should be able to launch their own UAS to get to scene before the boat arrives. That would require SAR stations to coordinate with Air Traffic Control. USCGC Chock’s sistership, 65 foot tug, USCGC Swivel, by Windwork50

Towed Airborne Lift of Naval Systems (TALONS)

DARPA’s Towed Airborne Lift of Naval Systems (TALONS) effort seeks to develop a low-cost, fully automated parafoil system to extend small ships’ long-distance communications and improve their maritime domain awareness. DARPA developed TALONS as part of Tern, a joint program between DARPA and the U.S. Navy’s Office of Naval Research that seeks to enable forward-deployed small ships to serve as mobile launch and recovery sites for medium-altitude, long-endurance unmanned aerial systems.

Navy Recognition reports on two initiatives that are part of the TERN,  “a joint program between DARPA and the U.S. Navy’s Office of Naval Research that seeks to enable forward-deployed small ships to serve as mobile launch and recovery sites for medium-altitude, long-endurance unmanned aerial systems.”

We have talked about TERN before, it is intended to allow the LCS and similar sized ships to have persistent overhead surveillance by Unmanned Air Systems (UAS). The post talks about a launch and recovery system for fixed wing UAS, “SideArm,” but there is also this discussion of a towed system that looks like it might be applicable to units as small as WPBs and give them many of the advantages of a UAS with far less overhead.

DARPA’s TALONS effort seeks to develop a low-cost, fully automated parafoil system to extend small ships’ long-distance communications and improve their maritime domain awareness. Towed behind boats or ships, TALONS could carry ISR and communications payloads of up to 150 pounds between 500 and 1,500 feet in altitude—many times higher than current ships’ masts—and greatly extend the equipment’s range and effectiveness. Following successful ground-based tests, DARPA will conduct at-sea testing this year and potentially transition the technology to the U.S. Navy.

Why is this important? With a mast head height of say 36 feet the horizon distance is only about 7 nautical miles. Go to 500 feet and it is over 26 miles. Go to 1500 feet and it is over 45 miles. Effectively search widths could be multiplied several times over.

It doesn’t take much power to keep a parafoil up. In my neighborhood, there is a good sized man who flies a powered foot launched version out of our local open space. He has the engine and prop on his back, launches into the wind with just a short walk or run. Landings are frequently at walking speeds. That people (admittedly braver than I) are willing to entrust their lives to these things has to say something about their reliability.

(Historical note: During WWII, the Germans used an manned unpowered autogyro, the Focke-Achgelis FA-330, that was towed behind U-boats in an effort to extend their visible horizon.)

Observations on the New Naval Strategy

I know many of you do not have the time or inclination to read the strategy, although it is not particularly long for such a document, so in addition to commenting on the contents, I will provide a Coast Guard “Readers Digest” version outlining the elements that are specific to the Coast Guard.

AN OVERVIEW:

In considering this strategy, it would be good to keep in mind this is not a strategy for war; it is a strategy for maintaining the peace, the sometimes violent peace that has become the new norm. As such, it assumes the Coast Guard will continue exercising its normal peacetime priorities. It does not define Coast Guard wartime roles or suggest how the Coast Guard might be shaped to be more useful in wartime.

If you look at the title, “A Cooperative Strategy for 21st Century Seapower: Forward, Engaged, Ready,” the words cooperative, forward, and engaged are particularly relevant in describing the thrust of the strategy.

It expects US naval forces to cooperate and engage with allied and friendly force both to improve relations and strengthen and encourage these friendly forces. The Coast Guard has a major role in this, in bringing expertise in a board range of governance functions that friendly navies and coast guards can relate to.

The Navy also expects to have a substantial part of its force “forward.” Not only forward but also geographically widely distributed. This violation of the Mahanian maxim to keep your battle force concentrated has been the norm for decades, but it has been a reflection of the preponderance of the US Navy that may be eroding. It is a calculated risk that the benefits of working with allies and being on scene to deal with brush fires, outweighs the potential risk of having an isolated Carrier Strike Group or Amphibious Ready Group overwhelmed by a concentration of hostile forces.

The strategy talks about surge forces, but frankly the potential is far more limited than it was when the Navy was larger. For the Coast Guard this “forward” strategy, combined with the apparently ever increasing concentration of US Navy forces in only a few homeports, has important implications. There are long stretches of the US coast that may be hundreds of miles from the nearest US Navy surface combatant.

If a suspicious vessel is approaching the US, that must be boarded to determine its nature and intent, the boarding is likely to be done by a Coast Guard cutter, and not by a National Security Cutter, but by something much smaller. The cutter is also unlikely to have any heavily armed backup.

ORGANIZATION:

Section I THE GLOBAL SECURITY ENVIRONMENT, talks about geopolitical changes since the strategy was last issued, and current military challenges.

Section II FORWARD PRESENCE AND PARTNERSHIP, looks at the specific areas of operation, specifically the Indo-Asia-Pacific, Middle East, Europe, Africa, Western Hemisphere, and the Arctic and Antarctic.

Section III SEAPOWER IN SUPPORT OF NATIONAL SECURITY, talks about the strategy in terms of missions, broken down as “All Domain Access,” Deterrence, Sea Control, Power Projection, and Maritime Security.

Section IV FORCE DESIGN: BUILDING THE FUTURE FORCE, attempts to describe the future force that it contends will be “Flexible, Agile, and Ready.” It goes on to talk about Forces, People, Concepts, and Capabilities.

GEOGRAPHIC PERSPECTIVE: The plan starts getting into specifics regarding the Coast Guard when it talks about specific regions.

Indo-Asia-Pacific Region

“The Coast Guard will rotationally deploy National Security Cutters and deployable specialized forces with the Navy and Marine Corps to safeguard U.S. territorial waters and the Exclusive Economic Zone (EEZ). Additionally, the Coast Guard will work with regional partners and navies using joint and combined patrols, ship-rider exchanges, and multinational exercises to build proficient maritime governance forces, enhance cooperation in maritime safety and security, and reduce illegal, unreported, and unregulated fishing. These multinational efforts are furthered through the Oceania Maritime Security Initiative and participation in the North Pacific Coast Guard Forum.”

Now I’m not sure what the first sentence is getting at. Usually when DETs deploy with the Navy, it is not for operations in the US EEZ, unless perhaps they are talking about the occasional deployment with ships transiting the US EEZ around islands in the Western Pacific, if so they might have been more specific. I don’t know why the strategy in several places refers to the National Security Cutter rather than simply cutters. I think this might have been an attempt to sell the NSC, which is a job now complete, but it frankly does nothing to justify the Offshore Patrol Cutter which can also do this type of work.

This is the first of several mentions of the Coast Guard’s potential for capacity building with navies and coast guards of friendly nations.

Middle East

The Coast Guard will deploy personnel to build partner nation capacity for maritime governance and simultaneously conduct maritime security, infrastructure protection, and Port State Control activities. Coast Guard patrol boats and deployable specialized forces on Navy and coalition ships will counter illicit maritime activity.

It does appear that the Coast Guard patrol boats in Bahrain are expected to remain there. Does this mean these now overage boats will be replaced in the future? Will they or their replacements receive weapons upgrades similar to those of the Navy Cyclone class counterparts?

Europe–No mention of the Coast Guard. Even so the CG will probably be involved in capacity building in Eastern Europe, as it has been in the past.

Africa–the Coast Guard is again mentioned in terms of capacity development and partnership station type activities. There is also interestingly a statement that a base will be developed in Africa.

Coast Guard District and Area Organization

Coast Guard District and Area Organization

Western Hemisphere

We will strengthen partnerships and capacity in the Western Hemisphere to protect the homeland and to counter illicit trafficking and transnational criminal organizations. Coast Guard recapitalization efforts will produce a fleet of highly capable, multi-mission ships and aircraft, including the Offshore Patrol Cutter and the C-27J Spartan maritime patrol aircraft to counter threats, particularly in the Caribbean Sea, Gulf of Mexico, and eastern Pacific Ocean. The Navy will maintain its base at Guantanamo Bay, Cuba, to support joint and combined military operations and to enhance interagency efforts to develop regional security and cooperation. The Marine Corps will employ task forces or SPMAGTFs to support security cooperation activities that increase interoperability with regional partners and strengthen their capacity to interdict transnational criminal organizations. We will employ amphibious ships and other platforms, including Littoral Combat Ships, Joint High Speed Vessels, Afloat Forward Staging Bases, hospital ships, other Military Sealift Command ships, and Coast Guard platforms, to conduct humanitarian assistance and disaster response missions. We will also employ maritime patrol aircraft such as the P-8A Poseidon and unmanned aerial vehicles. Other ships and aircraft will provide periodic presence for recurring military-to-military engagements, theater security cooperation exercises, and other missions.

That is the entire section. Surprisingly no specific mention of using Navy ships for drug interdiction. Use of Navy vessels is mentioned only in the context of “humanitarian assistance and disaster response missions” and “military-to-military engagements, theater security cooperation exercises, and other missions.”

Competing claims in the Antarctic

Arctic and Antarctic:

Consistent with the predicted growth in maritime activity, the Sea Services will assess Arctic access and presence needs, improve maritime domain awareness, and pursue cooperation with Arctic partners to enhance the maritime safety and security of the region. This will require us to further develop our ability to operate in the Arctic, including in ice-covered and ice-obstructed waters. The Coast Guard will apply the multi-mission capabilities of the National Security Cutter to provide a tailored seasonal presence for command and control and aerial surveillance, and will begin the design process for a new, heavy icebreaking capability to support operations in both the Arctic and Antarctic. The Coast Guard will also pursue the formation of a maritime assistance, coordination, and operations group, open to members of the eight Arctic Council nations. The purpose of this group will be coordination of multinational search and rescue operations, training exercises, maritime traffic management, disaster response, and information sharing.

Again this is the entire section. DOD Maritime Domain Awareness is going to be very important here, and apparently it is already good. Looks like the Navy is content for the Coast Guard to be the face of US Naval presence in the Arctic. Again there is reference to the NSC which is not ice-strengthened and no mention of the OPC which is.

MISSION PERSPECTIVE: The Strategy refers to five essential functions–all domain access, deterrence, sea control, power projection, and maritime security.

All domain access: Not surprisingly there is no mention of a Coast Guard role in kicking in the door.

Deterrence: “The Coast Guard maintains a continuous presence in our ports, internal waterways, along our coasts, and offshore, providing an additional layer of defense against maritime threats.”

Sea Control: There is no mention of a Coast Guard role in Sea Control. There should be. Sea Control frequently involves Visit, Boarding, Search and potentially Seizure of non-military vessels, e.g. merchant and fishing vessels. The Coast Guard is ideally suited for this role and has conducted this type of operation in war zones in the past, notably the Markettime Operation during the Vietnam War. In fact the common Coast Guard missions of drug and alien migrant interdiction are forms of sea control that potentially protect the US from non-state actors, but these missions are reflected in the Maritime Security mission.

When it comes to counting assets that might be used to exercise sea control, the Navy has roughly 110 cruisers, destroyers, frigates, LCS, and patrol craft and many of these, particularly the 85+ cruisers and destroyers, probably will have higher priority missions. The Coast Guard includes over 100 patrol boats and about 40 larger patrol vessels that routinely exercise sea control on an almost daily basis.

Force Projection: No mention of a Coast Guard role in Force Projection.

121203-G-XX000-001_CPO Terrell Horne

Maritime Security: It is here that the Coast Guard truly comes into its own.

We conduct maritime security operations by locating and monitoring vessels suspected of carrying illicit cargo or persons. If required, we intercept and board these vessels in support of U.S. law or international sanctions. Operating with the Coast Guard’s unique legal authorities, naval forces combat the illegal drug trade, human trafficking, and the unlawful exploitation of natural resources, particularly in the Western Hemisphere. Maritime security operations further support the broad maritime governance activities of the United States. These include assuring access to ice-covered and ice-obstructed waters in the Arctic and Antarctic.

Because all nations share in the collective benefits of maritime security, it is a promising area for expanded cooperation with our allies and partners. Through multinational exercises and training, we will conduct maritime security force assistance to combat transnational organized crime and protect fisheries and maritime commerce. This function supports the naval missions of defending the homeland, protecting maritime commons, and strengthening partnerships.

FORCE DESIGN, BUILDING THE FUTURE FORCE

There is not a lot here specific to the Coast Guard. There is discussion about acquisition and personnel policies, but they appear to reflect Navy Department aspirations.

There is potential in the concept of modularity for allowing Coast Guard assets, particularly cutters, to more rapidly transition to a wartime outfit.

This section includes a listing of projected required capabilities tied to each of the missions discussed above. It is in the Maritime Security section that we find statements relevant to the Coast Guard and its missions:

To combat terrorism, illicit trafficking, piracy, and threats to freedom of navigation in the maritime domain, we will:
■ Increase our capabilities in integrated maritime detection, monitoring, and intelligence, along with those of our allies and partners, to improve global maritime domain awareness. This involves exploring more stringent Automated Identification System reporting requirements for vessels weighing less than the currently mandated 300 tons, as well as fielding innovative technologies that enhance effectiveness against the small vessel threat.
■ Strengthen the International Port Security Program to further ensure the integrity and legitimacy of commercial vessels and cargo traveling to our shores.
■ Enhance our interoperability and capability to perform visit, board, search, and seizure in contested environments.
■ Improve interoperability between Navy and Coast Guard vessels, aircraft, and shore facilities, in accordance with the National Fleet Policy to maximize sea control and maritime security capabilities.
■ Support our allies and partners through training, exercises, and the provision of capabilities, via foreign military sales and financing, to increase their capacity to address maritime security challenges.

EVALUATION:

This is not a war plan so much as a plan for preventing war. From a Coast Guard perspective, it has largely canonized the status quo and the existing recapitalization program of record. It recognizes the Coast Guard’s unique authorities and its ability to contribute to capacity building. It seems to promise greater integration of a multiservice Maritime Domain Awareness.

On the other hand it does nothing to define Coast Guard wartime missions or how it might transition to a wartime footing. The force structure section does nothing to inform the design of Coast Guard equipment so that it might be more useful in wartime. It also does nothing to help that Coast Guard patrol boat I talked about at the beginning that is about to attempt to stop and board a potential hostile vessel that may be about to make an unconventional attack on a US port.

This is only the second iteration of the three service cooperative strategy. It is a marked improvement in specificity over the previous document. Hopefully there will be a process of continual improvement in succeeding editions.

Office of Naval Research, “Naval Future Force Science and Technology Expo”

Don’t often mention “trade shows.” I don’t think I ever have, but this is one that the CG might want to attend.

What: Naval Future Force Science and Technology EXPO
When: Feb. 4-5, 2015
Where: Walter E. Washington Convention Center in Washington, D.C.

Among the things the Coast Guard might benefit from are developments in Maritime Domain Awareness, ship design and survivability, and developments in unmanned systems.

Perhaps not immediately applicable to the Coast Guard, but looks like they will also have a good discussion on development of electromagnetic railguns. These might have the advantage for the Coast Guard of being effective ship stoppers, while having the advantage of requiring no explosives be carried on the ship–a good reason for the new ships to have robust generator capacity.
