Open to Collaboration
Later, both BAE Systems and General Atomics announced that they had responded to Japan’s invitation to collaborate on the railgun technology.
Before its cancelation, BAE Systems was the primary contractor on the railgun program tasked to materialize the US Navy’s attempt to field the futuristic weapon. The program kickstarted in 2005 as a naval surface fire support weapon seeking to support US Marines operating ashore. The Navy later realize the weapon’s further potential, expanding the program’s scope to include intercepting missile capabilities. By 2010, General Atomics joined the bandwagon and created their prototype for the Navy and a land-based variant for the Army to be mounted on tanks or employed as long-range artillery. But like its sea-based counterpart, the land-based railgun project never came to fruition.
In an emailed statement to National Defense, BAE Systems spokesperson Tim Paynter confirmed that the company had contacted the Japanese government regarding the matter. He added, “We work closely with the US Department of Defense to support international allies and partners and provide innovative solutions to deter current and future threats.”
On the other hand, General Atomics Electromagnetic Systems Group (GAESG) has also responded via an emailed statement that the company has expressed eagerness to work with Japan on the railgun project.
“Over the last year, [GAESG] has met with both [Acquisition, Technology and Logistics Agency] and Japan Steel Works a number of times to discuss Japan’s railgun program,” said Meghan Ehlke, a GAESG representative.
“Not only would we welcome the opportunity, [GAESG] looks forward to working with the US and Japanese governments in helping Japan increase their defense capabilities,” she said.
Japan’s call for partnership on the technology makes sense considering the US experience despite failing to progress further.
“If we can demonstrate the railgun, the United States might change its mind on the technology,” Mishima said, adding that if successful, it would be a win-win for everybody.
Japan’s Railgun Program
Having to sit in an increasingly volatile region, with threats from North Korea and China, Japan has shed its previously pacifist approach and gradually ramped up its military strength and capabilities. Its efforts include doubling its self-defense budget and allocation to pursue R&D efforts on advanced technologies such as the railgun.
According to reports, the Japanese government set aside 6.5 billion yen ($56 million) last year for a railgun-based counter-hypersonic weapon system and expects to field it by 2030.
But then again, considering the long, complicated development history of the electromagnetic weapon and its demanding requirements, would this goal be feasible even with the help of American defense contractors?
Peter W. Singer, a strategist at the New America think tank, has pointed out the railgun’s significant application “in areas ranging from anti-missile to strike, you name it,” if both developers can address its existing technical issues—with emphasis on the if. Nevertheless, he remains optimistic that the fielding of railgun will one day come.
“A key is not just the potential speed and range, but the relative cost per shot versus a missile,” he added.
The railgun may have been a concept since the early 20th century, but technological development has been slow and fraught with challenges. Despite this, Japan remains committed to pursuing it as a top research priority. By collaborating with US defense contractors with expertise in railgun technology, the country hopes to take a step further in the development phase. If successful, the railgun could increase Japan’s defense capabilities and serve as a deterrent against potential threats, at the same time, a valuable asset and a dream come true to the US.
