Yes, I remember the difficulties with component tracking and part numbers. For some reason REACH didn't see to cause the same consternation. At least not that I noticed. I guess it's becasue REACH was more of a reporting function.
Actually, among the high-end embedded board-level products we covered, RoHS seemed to affect most the manufacturers that served both mil and commercial customers, since they often ended up running two separate lines for two different versions of the "same" product. Mil-only board manufacturers were not affected much until later. One thing that did affect them both was the nightmare of components tracking and part numbers changing.
Since there were only two of us, myself and the editor-in-chief, I did a little of everything. Mostly we did not address distribution, but design and development technologies for HW and SW, comms, and a lot of board-level products and technologies. I wrote several features on RoHS, too.
As I learned working for COTS Journal, COTS doesn't just mean actual end-system computers and apps software. It can also refer more broadly to both software and hardware design and development platforms, specifically for creating end-system hardware and software used in the field. Ruggedization is taken for granted for military field use; that feature doesn't determine whether a machine is COTS. A COTS-based machine may also be further tweaked--and usually is--for specific apps. The big difference is that the military is no longer spending zillions of dollars on proprietary, entirely customized systems.
What I've heard is that the COTS stuff is used for office and support functions. When it comes to electronics out in the field, the electronics are ruggedized (and leaded) so they can withstand a difficult environment over many years.
The COTS systems, platforms, networking technologies, and software are, as the term says, commercial off-the-shelf hardware and software, meaning stuff that's originally designed and built for the rest of us. Basically, that means the military is using Windows-based laptops and other standard commercial hardware and software, as well as standard networking protocols, which is actually kind of scary. This is instead of spending zillions of dollars on designing their own stuff, like in the "good old days." Even the NSA buys a lot of standard signal-processing equipment.
Interestingly, many of the older "antiques"--more like family heirlooms--in my house are made of bio-based materials, such as wood and paper (which also used to be considered sustainable materials until we nearly used them up), or ceramics and brick, which are sustainable. Even metals were sustainable, and still are. Most of these materials are commonly found in the rubbish heaps of our ancestors, and give archaeologists a lot to study. Much of the problem with materials becoming non-sustainable has occurred in more recent times because of overuse (due in part to enormous population growth), as well as because of newer materials with complex processes and polluting wastes.
Optomec's third America Makes project for metal 3D printing teams the LENS process company with GE Aviation, Lockheed, and other big aerospace names to develop guidelines for repairing high-value flight-critical Air Force components.
A self-propelled robot developed by a team of researchers headed by MIT promises to detect leaks quickly and accurately in gas pipelines, eliminating the likelihood of dangerous explosions. The robot may also be useful in water and petroleum pipe leak detection.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
