NAIS for Command and Control/”The USCG RDC & Electronic Aids To Navigation”–Marine Link

Marine Link has an excellent overview of the increasingly useful Nationwide Automated Identification System (NAIS) and the R&D Center’s role in its development.

As for the Coast Guard’s own use of the system, we have this press release from FLIR.

WILSONVILLE, Ore., October 16, 2018 – FLIR Systems, Inc. (NASDAQ: FLIR) announced today that it has been awarded a contract from the United States (U.S.) Department of Homeland Security (DHS) in support of the U.S. Coast Guard’s (USCG) Second Generation Automatic Identification System (AIS-2) program. The indefinite delivery indefinite quantity (IDIQ) contract has a ceiling value of $9.9 million to provide second generation Automatic Identification System (AIS) transponders, associated peripherals, and spare parts for nearly 1,774 boats and 282 cutters in the USCG’s active fleet.

The government anticipates the purchase of vessel class-specific kits and spare parts to equip all USCG vessels with AIS-2 over the next five years.

“We are pleased to provide AIS hardware and software technology to support the US Coast Guard’s mission,” said Jim Cannon, President and CEO at FLIR.  “Our technology will provide enhanced levels of secure communication and coordination between Coast Guard boats, cutters, and shore stations (emphasis applied–Chuck). This award further extends our technology partnership with the Coast Guard, providing next-generation communication capabilities to complement their Raymarine SINS-2 navigation systems.”

I was a little surprised to see reference to secure communications in conjunction with AIS because I don’t associate those two things, but it is apparent we are finding new uses for the system, including as a blue force locator.

It looks like we will be putting these systems on even our smallest boats. Ran across a study that may provide an indication (Note this is apparently a Russian URL) of where we are going with this.

Icebreaker Communications Requirement

A 4ISRnet report confirms that the Coast Guard intends to have a full range of communications equipment on the new Heavy Polar Icebreaker, up to an including military secure satellite communications.

“Communication is severely degraded at higher latitudes, beyond 65 degrees north and south,” said Eric Nagel, a spokesman for the Coast Guard’s acquisition directorate. “Coast Guard polar icebreakers need to be able to communicate in Polar Regions with a wide range of groups from commercial shipping and recreational boaters to scientific researchers. The polar icebreakers also need to maintain network connectivity with the Department of Homeland Security, Department of Defense and other federal and international partners.”



JPALS landing aid for Coast Guard?

The Navy has already chose Joint Precision Approach & Landing Systems (JPALS) and BreakingDefense reports Raytheon is offering it to the Air Force and Army. Perhaps the Coast Guard should take a look. Like the Navy, the Coast Guard operates aircraft from moving ships, with perhaps even more  “pitch, roll, surge, sway, heave, yaw, and translation”

JPALS fills the role of a TACAN, giving bearing and range to the landing area, but does it with much greater accuracy, directing the aircraft to a 20 cm (7.8″) square area, using differential GPS. It does it all in any weather and zero visibility with very low probability of intercept and in an encrypted format by data link, minimizing the need for radio communications.

Every time we turn on TACAN we broadcast the position of ship. 

Potentially it can provide a autonomous recovery for aircraft and UAVs.

“What’s more, Raytheon is finishing development of a capability for JPALS to take over the flight controls and bring the aircraft in for an automated landing with no input from the pilot – or potentially with no pilot on board at all. That is why the Navy has contracted with Raytheon to put JPALS on its future MQ-25 carrier-based drone.”

Maybe our over-the-horizon boats could use it too.

JANUS, the Standard Underwater Language

NATO has announced,

The NATO Science and Technology Organization’s Centre for Maritime Research and Experimentation has developed a standard for underwater acoustic communications called JANUS, which is recognised as a NATO standard by all NATO Allies since 24 March 2017. This marks the first time that a digital underwater communication protocol has been acknowledged at international level and opens the way to develop many exciting underwater communication applications.

I think this might become important to us. It is not just a military system.

Thanks to EagleSpeak for bringing this to my attention. 

Equipment for the Offshore Patrol Cutter


The National Fleet Plan had some clues regarding equipment that we can expect on the Offshore Patrol Cutter (OPC). Apparently there will be a lot of commonality between the Navy’s LCS and future generation frigates, the Coast Guard’s Offshore Patrol Cutters (OPC), and the Bertholf Class NSCs. My last discussion of the equipment on the OPC can be found here: “Offshore Patrol Cutters (OPC), the Other LCS” which contains information not addressed here. Generally the information below does not look much different but I will try to point out any significant differences.

Command, Control, and Communications (Ref. Section 5.5):

The recommended NTNO (Navy Type Navy Owned–Chuck)systems to meet C3 commonality and interoperability for the OPC are as follows: MIL UHF LOS 225-400 MHZ (Digital Modular Radio (DMR), ARC-210, PRC-117); MIL UHF SATCOM (DMR, ARC-210, PRC-117); Messaging (DMR SATCOM, ARC-210, PRC-117); Tactical Data Link (LINK 11; Joint Range Extension (JRE) Link-16, forwarded LINK 22); VACM (KY-100M, KY-58M, KYV-5M). (p. 22)

I am very pleased to see LINK 11, 16, and 22 on the list although this is probably a “junior edition” of these systems. These systems are becoming so ubiquitous if you don’t have them, you are more of a burden than an asset. The table on page 24 seems to indicate that the OPCs will not have an airsearch radar, but will have a multi-mode radar that will be common with Navy systems (p.50). Its not clear what that will really mean for the ship’s capabilities. As far as I can tell, the only air search on the NSCs is the EADS 3D TRS-16 which is also a multimode radar combining air search, surface search, and fire control functions. This radar is likely to be replaced by the newer EADS Cassadian TRS-4D multi-function radar.

Sensors (Ref. Section 5.6): The OPC will have a multi-mode radar, Electronic Warfare Systems, Decoy launching system, Sensitive compartmented information Network, TACAN, and CCOP (Cryptologic Carry-On Program).

 The recommended systems to meet Sensor commonality and interoperability for the Offshore Patrol Cutter are as follows: TACAN; Multi-Mode Radar; IFF; SEWIP (SLQ-32/SSX-1 replacement); and MK-160 Gun System. (p. 25, 5.6.b.2)


Weapon Systems: The OPC will have a 57mm, 25mm, and .50 cal guns. (It is not addressed in this document, but there have been indications that two of the .50 cal. are to be mounted in stabilized remotely controlled weapon stations. The 25mm will presumably be a Mk38 mod2 or 3) The OPCs will not incorporate either a CIWS or degaussing (p.32). (I do have reason to suspect that the OPC is fitted for upgrade to include CIWS.)

It will also have ADNS (Automated Digital Network System), Sensitive Compartmented Information Network (SCI-Networks), Consolidated Afloat Networks and Enterprise Service (CANES).

Notes on the Ship’s Signals Exploitation Equipment System and Unmanned Aircraft System, “OPC has the same space, weight and power requirements (as the NSC–Chuck) reserved but a system has not been selected.” (p. 24)

It appears the gun firecontrol system, may include only Electro-Optical control cued by the multimode radar, and that it will not include the AN/SPQ-9B which is used on the National Security Cutters (I think this may be a change).  There is a note on the Gun Fire Control System: “OPC will have a fire control radar capability (MMR-presumably multimode radar–Chuck) to provide tracking information and slew of the GWS camera, but slew and fire of the GWS cannon remains under manual control.” (p.24) Hopefully, an integration of the multimode radar with the weapon 57mm and perhaps the 25mm will permit blind firing of these systems, otherwise some visibility conditions may preclude effective fire control and certainly reaction times, particularly against air targets, will not be as good as they might have been.

Keep a Camera on the Bridge

MarineLog passed along a recommendation that a good camera be regarded as essential bridge equipment.

Their advice:

…as a minimum:

  • a digital compact camera with at least 8X optical zoom, built-in flash and video function; camera image quality of at least 10 megapixels;
  • two 8GB or larger blank SD cards (preformatted) and checked for operation;
  • spare battery pack;
  • mains charger with ship-compatible plug

“The camera should be kept on the bridge, fully charged with an empty storage card. Most cameras have an internal clock which should be checked and set to UTC. This time-stamp is used when the image file is stored, essential when the chronology of events could be questioned,” says Mr. Harrison. (Mike Harrison of marine consultancy Solis Marine Consultants, Ltd.–Chuck)

Their focus is on insurance claims, and while that certainly applies to the Coast Guard, we have other reasons to want video documentation. Good video is useful for public information and for training. It can help with evaluating and passing along lessons learned. It can also become valuable evidence in criminal cases.
