Is The Zumwalt’s Stealthy Design Ultimately Seaworthy?

The Navy’s massive destroyer, the Zumwalt, has been designed to be stealthy, powerful, and equipped with some of the most impressive defensive technology.

It’s design is anything but ordinary and plays a key role in its impressive capabilities, as well as its reduced operational costs, low radar profile, and energy efficiency.

However, the Zumwalt’s unconventional structure have led some to question just how seaworthy this massive warship will be when faced with certain conditions. Is this massive ship ready for everything the ocean and our naval enemies might throw at it?

Stealth And Stability
The Zumwalt’s hull is most notable for the angular and sloping structure of its hull. Its trapezoid-like shape has been chosen for its ability to cut through waves and deflect radar signals, making the 600 foot long and 15,000 ton warship look like a small fishing vessel to enemy radar.

The hull’s design is a modern take on pre-dreadnought battleships that has been engineered and tested for the demands of today’s naval ventures.

Although a large scale model has already been tried as a proof of concept and the Navy has run extensive computer modeling and virtual simulations on the Zumwalt in a range of conditions, there are still concerns over just how stable the ship will be in unpredictable, real world circumstances.

Critics have said the ship’s stealth features could also amount to stability issues if the Zumwalt were to sustain battle damage.

A Lot Riding On This Ship
With a $4.4 billion price tag on the first ship alone and an important role to play in the Obama administration’s Asia-Pacific naval strategy, there’s a lot riding on the Zumwalt and the Navy’s assurance that its indeed seaworthy.

Bath Iron Works, the Zumawalt’s shipbuilder, will be completing performance tests and making necessary modifications this winter and is aiming to turn the ship over to the Navy in 2016.

Military Autonomous Vehicles Reduce Personnel Threats But Raise Ethical Questions

Just as developers of autonomous vehicles for civilian roads grapple with programming life-and-death decisions, the defense industry must contend with when and if autonomous equipment should strike a target. Will autonomous military vehicles have an independent ability to make firing decisions or always require human approval for lethal action? With autonomous technologies advancing rapidly, military leaders are now confronted with practical instead of theoretical questions.

West Point Student Smart Machine Exercise

An exercise at West Point had students consider ethical scenarios while testing the other military benefits of autonomous military equipment. Students largely felt uncertain about the amount of authority the machines should be given. The possibilities for independent machine actions have also left military leaders pondering how much control to give up to autonomous machines on a battlefield.

Supportive Military Role

Short of firing weapons based on nonhuman algorithmic decisions, autonomous military vehicles have clear roles to perform in military environments. Rheinmetall, a Canadian defense contractor, has designed a modular unit that soldiers can outfit for different purposes.

Attachments for the autonomous vehicle offer reconnaissance and surveillance functions. The vehicles can also transport personnel in or out of operational areas. They could retrieve wounded people and evacuate them. Other attachments aid in fire fighting or enable detection of radiological, chemical, or biological hazards.

Protecting Personnel From Harm

Autonomous vehicles would reduce risks for military personnel. They could send the machine to perform reconnaissance or sweep for hazardous materials. Machines could enter hostile zones and exchange fire with opponents.

Air, Sea, And Land

Engineers have proposed many uses for autonomous vehicles. Unmanned naval vessels could pursue submarines underwater or fire weapons from offshore to support Marines on a beach. The U.S. Army is currently experimenting with machines that locate enemies and supply tanks with targeting information. The U.S. Air Force has plans for advanced drones that would work in conjunction with fighter planes.

Do you think that military scientists will achieve the next breakthroughs in autonomous vehicles? Comment with your thoughts on where this will lead.

ABOUT West Point

West Point’s role in our nation’s history dates back to the Revolutionary War, when both sides realized the strategic importance of the commanding plateau on the west bank of the Hudson River. General George Washington considered West Point to be the most important strategic position in America. Washington personally selected Thaddeus Kosciuszko, one of the heroes of Saratoga, to design the fortifications for West Point in 1778, and Washington transferred his headquarters to West Point in 1779.

The U.S. Military Academy at West Point’s mission is “to educate, train, and inspire the Corps of Cadets so that each graduate is a commissioned leader of character committed to the values of Duty, Honor, Country and prepared for a career of professional excellence and service to the Nation as an officer in the United States Army.”

ABOUT Rheinmetall

Rheinmetall Canada offers innovative solutions for vehicle systems and integration, air defense as well as weapon, command and communications, soldier and robotic systems. Furthermore, the offering includes airport ground support equipment. Rheinmetall Canada also customizes systems to the evolving operational needs of military forces in Canada and on selected international markets and is principally engaged in long-term, in-service support for the broad range of solutions.

In addition to offering its own solutions, Rheinmetall Canada provides the Canadian market with Rheinmetall’s broad portfolio of system solutions, services and technologies in the areas of mobility, reconnaissance, management, effectiveness, simulation, and protection.

U.S. Air Force Embraces Digital Twin Technology

Military weapons designers within the WeaponONE program at the Air Force Research Laboratory can now analyze real-time feedback from in-theater weapons within a digital engineering environment. Known as digital twin technology, it mirrors the activity of a weapon or other machine and analyzes incoming data for the purpose of fine-tuning future operation. This allows researchers to identify problems and test solutions digitally so that they can be adopted rapidly during military operations.

Rapid Weapon Adaptations and Improvements Possible

Powerful computers supported by artificial intelligence look for ways to upgrade hardware performance and precision based on the data supplied by real-world conditions experienced by a system in action. The discoveries revealed by a concurrently running digital twin can translate into immediate or near immediate software adjustments that increase weapon efficacy.

Air Force Research Lab rocket engine test stands at Edwards Air Force Base, Mojave Desert, California.

Gray Wolf Demonstration

The WeaponONE program demonstrated this marriage of hardware and machine-learning software on Jan. 21, at Eglin Air Force Base in Florida with the Gray Wolf prototype. Gray Wolf is an experimental cruise missile meant for clustered deployment against enemy air defenses.

Gray Wolf involves a 24-hour Air Tasking Order cycle that enables the missiles to collaborate. During the demonstration, officials saw how WeaponONE gathered in-flight data and cross-referenced it with information about the battlefield. This data went through the Advanced Battle Management System and then entered the digital twin for analysis.

New Era of Digital Weapon Engineering

Military scientists expect the digital twin concept demonstrated by WeaponONE to herald the next generation of military weapons engineering. The process speeds weapon development and results in products capable of rapid adaptations in the face of fluid military operations.

Digital twins certainly have applications beyond military purposes. The insights possible by analyzing a virtual representation of a real-world operation can assist manufacturers in many industries by helping them speed up product assembly and increase factory efficiency. Which military and nonmilitary sectors do you think have the most to gain from digital twinning?

DARPA Wants To Engineer Plants That Serve As Spies

In combat, unconventional sources of intelligence can provide a major advantage when completing a mission and keeping troops safe. DARPA is now working on a technology that could enable the military to gain tactical insight from a very unexpected source: plants.

Detecting Hazards In The Field

By modifying the genes of certain plants, the Defense Department hopes they can be turned into valuable indicators of battlefield conditions, such as the presence of chemicals, pathogens, radiation, and even buried explosive devices. Such capability would rely on plants’ natural responses to environmental changes and various stimuli. DARPA has devoted a new program, Advanced Plant Technologies (APT), to turn plants into reliable battlefield spies.

Tough And Discrete Enough For The Military 

One challenge for making this a reality is creating strains of plants that provide a reliable and readable response to specific stimuli while also ensuring the plant is hardy enough to survive in nature. While previous attempts have successfully produced plants that behave like sensors, they haven’t been as robust as required for this type of defense application. The Department of Defense is now calling for proposals from scientists who can contribute to APT with ideas for cultivating a hardy, healthy plant that appears natural in its environment and can also dependably reveal combat hazards.

An Open Call For Contributions

Potential contributors to the program will have an opportunity to share their proposals at a special DARPA event to be held on December 12th in Arlington, Virginia. Will the APT program ultimately yield plants that rival advanced intelligence gathering technology?

Tell us what you think about this DARPA pursuit in the comments.
