U.S. Navy Has a Coastal Mine Detection System

U.S. has a coastal mine detection system reports Megan Eckstine at USNI News

The Navy completed the first phase of its initial operational test and evaluation on the AN/DVS-1 Coastal Battlefield Reconnaissance and Analysis (COBRA) airborne mine detection system and is awaiting Littoral Combat Ship availability to complete the remaining testing.

COBRA is a sensor payload that operates onboard the MQ-8B Fire Scout and can detect beach zone mines in the daytime to help plan amphibious landings. An eventual block upgrade would add nighttime and surf zone detection capabilities.

Using air vehicle operators and mission payload operators from Air Test and Evaluation Squadron (VX) 1, maintainers from Helicopter Sea Combat Squadron (HSC) 21 and operators from USS Independence (LCS-2) and the LCS Squadron (LCSRON) 1, the LCS program proved to the Operational Test and Evaluation Force that COBRA can effectively and reliably meet its mission requirements.

“Right now, in order for us to do the kind of reconnaissance you need in advance of an amphibious landing, you’ve got to put sailors and Marines, you’ve got to put somebody in there with eyes on target to see what’s there, see if there’s any obstacles. People are involved in it,” Taylor said.
“With this capability, you’re able to go from the LCS with an unmanned vehicle, you’re able to recon a whole line of beach – not just one or two areas, you can look at the whole beach, you can look at all the lanes that are possible without putting somebody there – which allows you to come back and look at that and choose which lane or lanes are available and which are not.”

More on COBRA here:

The COBRA airborne payload will be carried on the MQ-8 Fire Scout unmanned air system. This allows operators and other personnel to remain at a safe distance from the mine and obstacle belts and enemy direct and indirect fire. COBRA will be embarked in the Littoral Combat Ship (LCS) as part of the mine countermeasures (MCM) mission package (MP).

Wonder who will protect the LCS at its "safe distance." And what is that distance in today's battlespace?

A New Generation of Fighter Aircraft Engines?

Aviation Week reports GE Advances Future Fighter Engine

Development of revolutionary engines at GE Aviation is setting the stage for the next 50 years in military aircraft propulsion, engineers there believe.

The engine can adapt in flight to give maximum thrust or long-range cruise, while a third stream of air will cool both the engine and the aircraft’s systems, explains Jean Lydon-Rodgers, vice president and general manager of GE Aviation’s military systems.

“The sixth-generation fighter engine is a big piece of the future of the business. That’s why we’re investing heavily in it,” says Lydon-Rodgers.

That investment also involves materials including ceramic matrix composites and titanium aluminides, and techniques such as additive manufacturing, to make the engines lighter and more robust while running hotter and providing more power. The military engines are benefitting from GE’s huge investment in such materials and manufacturing readiness for its next generation of commercial engines, which helps keep the costs down for the warfighter, she says.

Innovation! More range for fighters? Will this allow aircraft carriers greater stand-off range and improve our maritime security? Sure sounds like it.

Let me recommend again Vaclav Smil's Prime Movers of Globalization: The History and Impact of Diesel Engines and Gas Turbines, now available for Kindle:

What makes it possible for us to move billions of tons of raw materials and manufactured goods from continent to continent? Why are we able to fly almost anywhere on the planet within twenty-four hours? In Prime Movers of Globalization, Vaclav Smil offers a history of two key technical developments that have driven globalization: the high-compression non-sparking internal combustion engines invented by Rudolf Diesel in the 1890s and the gas turbines designed by Frank Whittle and Hans-Joachim Pabst von Ohain in the 1930s. The massive diesel engines that power cargo ships and the gas turbines that propel jet engines, Smil argues, are more important to the global economy than any corporate structure or international trade agreement.

Save the Whales: NOAA has an app for that

NOAA announces that a "New iPad, iPhone app helps mariners avoid endangered right whales":

Mariners along the U.S. east coast can now download a new iPad and iPhone application that warns them when they enter areas of high risk of collision with critically endangered North Atlantic right whales. The free Whale Alert app provides one source for information about right whale management measures and the latest data about right whale detections, all overlaid on NOAA digital charts.

“Whale Alert represents an innovative collaboration to protect this critically endangered species,” said David Wiley, NOAA’s Stellwagen Bank National Marine Sanctuary research coordinator and project lead. “Whale conservation is greater than any one organization and this project shows how many organizations can unite for a good cause.”

A key feature of Whale Alert is a display linking near real-time acoustic buoys that listen for right whale calls to an iPad or iPhone on a ship’s bridge showing the whale’s presence to captains transiting the shipping lanes in and around Stellwagen Bank National Marine Sanctuary. “The idea that right whales are directly contributing to conservation through their own calls is pretty exciting,” said Christopher Clark, whose team at the Bioacoustics Research Program at the Cornell Lab of Ornithology helped develop the acoustic detection and warning system.

North Atlantic right whales, which live along North America’s east coast from Nova Scotia to Florida, are one of the world’s rarest large animals and a species on the brink of extinction. Recent estimates put the population of North Atlantic right whales at approximately 350 to 550 animals. Collision with ships is a leading cause of right whale death.

Way cool.

Gotta love the technology.

Somali Pirates: A Techno Fix?

DefenceWeb suggestions for modern ways of fighting Somali pirates in "Technology there to find, fix, finish pirates":

Finding pirates before they can launch attacks requires a fully integrated intelligence, surveillance and reconnaissance cycle: Intelligence to build an initial picture of the situation; surveillance to develop and update that picture; and focused reconnaissance to add detail and follow up leads to further refine that picture.

UAV

The key elements required to perform this function will include shore-based radars, maritime surveillance and patrol aircraft and unmanned aerial vehicle systems (UAVS); patrol vessels of several types, with embarked helicopters or UAVS; shore-based fixed and mobile sensors, including radar and optronic sensors, and electronic intelligence gathering systems to monitor radar emissions and communications signals.

Fast Manned Patrol Boats

Fast Unmanned Boats

Money to fund this work is, of course, the drawback. The rest of it is essentially correct. As has been discussed here before, the key is to, one way or the other, blockade the pirate operating areas. See, Somali Pirates: U.S. Senator Proposes Legislation for Counter Piracy, Somali Pirates: Hmmm . . . is a pirate port blockade coming? and the links therein. In the latter post, by the way, I touched on the use of UAVs, USVs and more to help in the blockade:

Manned Patrol Aircraft

Anti-Pirate "Mothership"

Containment involves limiting the damage that can be caused by pirates. This can be carried out by naval patrols, convoys, establishing safe routes and blockades of pirate ports, the very sort of activity we now see by naval units in the area.

Drones, patrol aircraft and lots of small fast boats to run down anything that leaves known pirate hangouts.

It could work.

Computer Modeling to Fight Sea Pirates

While I don't pretend to understand all the aspects of what this involves, the Agent Technology Center is employing its process to aid in the anti-sea pirate fight, as set out in Agentc - Projects:

We explore how multi-agent systems, a branch of artificial intelligence, can be used to improve maritime security, with particular focus on fighting maritime piracy. Our ultimate objective is to develop an integrated set of algorithmic techniques for maximizing transit security given the limited protection resources available. We achieve this by improving the coordination of the movement of merchant vessels and naval patrols, while taking into account the behavior of pirates.

In order to evaluate the proposed techniques and to gain better insight into the structure and dynamics of maritime piracy, we also employ agent-based simulation and machine learning techniques to build dynamic models of maritime transit and to model and assess piracy risk.

All methods are implemented within a modular software testbed featuring a scalable simulation engine, connectors to real-world data sources and powerful visualization front-end based on Google Earth.

Got that? Well, here's a video:



UPDATE: Nice visual of sea lanes, a thwarted pirate attack and more. Suggest using full screen mode. Setting of optimal patrol sectors on transit lane is interesting.
