Western navies are adding new technologies to counter mines
Printed headline: LIFEGUARDS
Unmanned and autonomous underwater vehicles are playing a greater role in the technology and tactics of mine countermeasures, even as Western navies evaluate different ways of dealing with these weapons.

The U.S. Navy, for example, is embracing new concepts such as modular capabilities incorporated as an organic part of the combat system of major warships and submarines, while getting rid of many dedicated mine countermeasure (MCM) vessels, particularly the Italian-designed Osprey-class. Most European navies, on the other hand, still put their money on the proven 1980s concept of the dedicated minehunter, despite the complexity and expense, on a cost-per-ton basis, of these vessels.

Meanwhile, industries in various parts of the world are proposing their own concepts and technologies for the detection, classification, identification and destruction of mines. Some even claim that a small support vessel and a rigid-hull inflatable boat are all that's needed to take a containerized MCM system to sea and operate it effectively. In all these approaches, unmanned and autonomous underwater vehicles are emerging as critical components of operations.

The state-of-the-art in the minehunting navies of Europe is based on dedicated vessels equipped with an advanced MCM combat-management system, hull-mounted minehunting sonar, forward-deployable, variable-depth minehunting sonar on a tethered, remote-controlled unmanned underwater vehicle (UUV)-like the Double Eagle Mk II or Mk III from Saab Underwater Systems-and a mine-disposal system. The latter is normally based on a smaller UUV that either places a disposal charge or blows itself up next to a mine. Examples include the Atlas Elektronik Seafox, BAE Systems' Archerfish, ECA's K-Ster and the Kongsberg Minesniper. Among suppliers of mine-disposal charges is Nordic Defense Industries of Denmark, which supplies the Damdic system.

The minehunting command-and-control and sonar market is dominated by Atlas Elektronik of Germany and by Thales Underwater Systems of France. Other leading suppliers include Kongsberg in Norway, which teams up with that country's FFI defense research institute, and EDO Systems, Lockheed Martin and Raytheon in the U.S. Major suppliers of UUVs include Atlas Elektronik, France's ECA, Gaymarine of Italy and Saab Underwater Systems in Sweden.

The next generation of minehunting systems will likely be based on autonomous underwater vehicles (AUVs), the first of which are already in use. Norway, for example, has deployed Kongsberg's Hugin 1000 AUV on the minehunter KNM Karmoy since 2004. After deployment from a ship, AUVs are typically capable of performing fully autonomous minehunting missions, rapid environmental assessments or other reconnaissance for up to 24 hr.

Of the leading minehunting sonar manufacturers, most are developing side-looking synthetic aperture sonar (SAS) systems for AUVs and towed bodies. These are based on the same principle as synthetic aperture radar: they use the forward movement of the platform to artificially lengthen the aperture of the antenna, thereby enhancing the resolution of the sensor. Under ideal conditions, the result is near-photographic sonar images of the seafloor, in which operators or target-detection algorithms can detect and classify minelike objects.

Kongsberg and FFI have developed an SAS system that has been extensively sea-tested on the Norwegian navy's Hugin 1000 AUV. Thales Underwater Systems is also working on SAS minehunting sonar for AUVs. Thales has teamed with U.S.-based Bluefin Robotics, which provides the AUV technology on which the Thales sonar has been demonstrated and tested.

In addition to these programs, Atlas Elektronik's main thrust in MCM is to develop a family of AUVs, of which the most significant model is planned to be the Sea Otter Mk II. Development of the vehicle takes place in partnership with the Danish-based Atlas Maridan Co. (a subsidiary of the German company), and has recently been speeded up so that sea trials begin in mid-2007 and can be completed by the end of the year, says Margitta Hohmann, Atlas Elektronik's senior executive for mine countermeasures activities. "It is planned that Sea Otter Mk II will take part in the NATO-sponsored harbor protection trials that will be hosted by Germany in mid-2008," she says.

Two minehunting sonar technologies are in line to equip the Sea Otter Mk II. These were developed in the late 1990s for the German navy's Minehunting 2000 program that was canceled for budgetary reasons. "Atlas Elektronik has been able to salvage both technologies, which will become the baseline of our new generation of minehunting sonars that we are offering to the German Navy for incorporation into its upcoming AUV program," Hohmann says.

That program is expected to be for 12-15 Sea Otter Mk II vehicles, which will be procured by 2009. The vehicles will have a modular payload. A minehunting sonar payload is to be acquired for some. "The German navy has in mind to form a pool of AUVs that will be brought into service on dedicated minehunters or other ships, probably support ships on which a containerized control center could be installed," she notes.

The Sediment sonar, or "Sedis," is designed to detect mines that are buried beneath the seafloor, says Hohmann. "This can be coupled to our Seawolf UUV for the disposal of buried mines. Whether this capability will be required by the German navy is not yet certain. For now, the focus seems to be on the Proud Mine sonar (Promis), which is designed to detect mines placed on the seafloor or in the water column."

The Promis sensor is not based on synthetic aperture sonar, although it does incorporate SAS processing as a secondary capability. It relies primarily on what Hohmann calls multibeam, multi-aspect processing. This technique carves up the reflected acoustic signal received from the seafloor into multiple beams to cover a large sonar sector and "looks" at objects on the seafloor from multiple aspect angles. To do this, the sonar array developed by Atlas Elektronik features a high number of small sensors.

"During extensive sea trials for the Minehunting 2000 program, we found that synthetic aperture sonar requires ideal conditions, otherwise it does not work as well," says Hohmann. She describes ideal conditions as those in which the receive array can be positioned in the water with an accuracy of 1/16th the wavelength of the acoustic signal used by the sonar. "More often than not, wave action and current make this difficult in real operations."

Despite the advent of MCM mission modules, dedicated minehunters will continue to be needed, Atlas Elektronik believes. "Of course, there is new technology such as AUVs, but these are just little vehicles and have their limitations," says Hohmann. "Navies will always require a mix of systems, including AUV-based systems that can be operated from any craft as well as dedicated minehunters." According to Tronje Schneider-Pungs, a former German navy officer with minehunting experience who now leads Atlas Maridan, future minehunters will have a key role to play in post-conflict area-clearance operations. "With AUVs that would take too much time," he says. "AUVs, however, are ideal to provide a naval task group with an organic, fast-response capability to make sure a key channel is free of mines or to conduct a rapid environmental assessment prior to an amphibious landing. This is more about detecting to avoid the mines rather than actually clearing up a minefield."

Other companies have a different opinion. "We believe that the three Finnish minehunters may well be the last dedicated vessels of this type," says Jan Cederlund, sales manager at Saab Underwater Systems. "Future programs will favor containerized MCM systems that can be rapidly installed on almost any type of ship when needed, or be operated from the shore."

Saab is working closely with SwedeShip Marine and Abu Dhabi Ship Building (ADSB) on a Maritime Security Vessel concept that is based on the 26-meter (85-ft.) fast-supply vessel designed by SwedeShip. Four of these high-speed, shallow-draft ships are being built by ADSB for the UAE navy. In 2006, Saab successfully performed an in-country MCM demonstration on the first-of-class.

"The idea is to use the vessel's versatility by placing a containerized MCM system on deck and installing an operator console based on our 9LV Mk 4 combat management system in the space below decks," Cederlund says. "Using the crane that is fitted standard on the craft, our Double Eagle Mk III minehunting UUV can be deployed into the water and recovered."
