On the 6th of May, 1937, the aerospace industry was changed forever. As the infamous Hindenburg airship attempted to land in a New Jersey air dockyard, a small fire broke out aboard the ship. Within a few minutes the entire vehicle was engulfed in flames and 36 individuals inside the airship were killed (1). It was that disaster that seemingly put an end to the short lived era of zeppelins and airships for quite some time.
By far the greatest flaw of early 20th century airships was their reliance on hydrogen gas for buoyancy. Although hydrogen is “lighter than air” it also happens to be extremely flammable. It was this flammability that caused the Hindenburg to burn so violently. Thankfully, modern airships make use of helium, and not hydrogen, to make themselves buoyant. The primary benefit from using helium lies in the nature of the element. Helium is an inert gas, meaning that it will never react with any other element while still being lighter than air. Fast forward to 2016, some 80 years later, and it seems as if lighter-than-air vehicles could slowly be making a comeback. While most airships nowadays are usually found circling various sporting events, one aerospace company is trying its hand at something completely different. The Worldwide Aeros Corporation is currently working on what it calls the “Aeroscraft”. This 555 foot-long experimental lighter-than-air vehicle is designed to be able to transport large amounts of cargo nearly anywhere in the world (2). At first, the concept of airships ferrying cargo may seem a bit antiquated with modern infrastructure and technology. However, lighter-than-air vehicles such as the Aeroscraft offer numerous advantages over conventional fixed and rotary wing aircraft. The greatest advantage of airships lies in their efficient use of fuel. Simply put, airships allow for larger possible payloads at significantly lower costs. The efficiency of an airship is due to its use of helium gas. While fixed wing aircraft must fight the force of gravity in order to stay airborne, airships are able to glide effortlessly through the skies while using a fraction of the energy. This means that an airship such as the Aeroscraft will require less fuel than a similarly sized conventional aircraft. Another significant advantage of lighter-than-air vehicles is their ability to land nearly anywhere. Where fixed wing aircraft require runways in order to take off and land, airships only require a relatively small landing pad. This means that airships can transport cargo in areas where airports, roads, or railroads are non-existent. For example, the Aeroscraft could deliver supplies across the expanse of the Canadian north, where roads are only operable one month out of the year (3). While the future of airships is certainly exciting, we may have to wait a little longer before it is actually here. The Aeroscraft underwent testing in 2013 and since then Worldwide Aeros has been perfecting its internal components. Although there is no date set in stone, the Aeroscraft is expected to be ready for operation on a large scale within the next five years. If the Aeroscraft is a success, it could lead to a whole new generation of modern airships.

The United States’ Military is the world’s leader when it comes to fielding cutting edge technology on the battlefield. Part of the reason behind the technological superiority of the military lies in the government backed programs that help link private research to the public sector. One such program is called DIUx or “Defense Innovation Unit Experimental”.
Founded in the Silicon Valley during April of 2015, the primary goal of DIUx is to build a working relationship between the military and private technology companies (1). With help from programs such as DIUx, the United States’ Military has been able to utilize the latest technology available today. The list of new equipment includes everything from weaponized laser systems that destroy targets with ease to injectable sponges that stop hemorrhaging in a few seconds. Many, if not all, of these revolutionary weapons owe their start to privately run research companies. As a result of the success by DIUx technologies, Secretary of Defense Ash Carter recently announced the plans for the construction of a second DIUx research center in Boston, Massachusetts. Carter and his associates hope that this new east coast hub will further expand the reach of DIUx, giving the military more access to the newest technology available. This second location also strives to implement new strategies in hopes of increasing the efficiency by which new ideas are turned into working prototypes. If all goes according to plan, this second addition to DIUx will likely bring the United States back to the level of armament research and development which it maintained during the height of the Cold War. Although some believe that this may not be necessary, countries such as Russia, Iran, and China have already begun their own innovative processes for arms development. If the United States is to maintain its position atop the world’s weapons race then it is necessary to continue bridging the gap between the public and private sectors of research.
