I would clarify one point because I have considered the same question.
The process used to manufacture the gun has a significant impact on the environment. The company is proposing a method that has much lower impact at the stage at which the metal used in the device is treated. This method has potential defence system applications that go beyond the F-35 itself.
This is also a small company testing an idea. We are facilitating the interaction between that company and a department that may use the product.
