24 Navy | Spring 2018 is called Razorback, which is a mid-sized unmanned undersea vehicle (UUV) program that aims to produce mid-sized UUVs for deployment on submarines. Another similar, but larger, vehicle known as Snakehead — which is technically an accelerated acquisi- tion program rather than a prototyping effort — involves a large-displacement UUV. e Navy hopes to go to competition for those projects in the next one or two years. ere are other examples of prototyping programs that have made it to the fleet, like the Navy's REMUS 600 Autonomous Under- water Vehicle (AUV), which provides mine countermeasures to the fleet. REMUS was first used in 2003 during Operation Iraqi Freedom for mine detection, and it also found the black boxes from Air France Flight 447. ere's also the Mark 18 Mod 2 Kingfish, a UUV used for mine-detection missions. It was first deployed in 2013 and is meant to replace the Swordfish system. Another tool that has proved helpful in the Navy's prototyping process: 3D printers. Grant said Naval Undersea Warfare Center Division Newport has two 3D printers, and they have access to a third machine that can do metal 3D printing. In the past, if the Navy wanted to build a part for a system, it would need an engineer to design a part, which would then have to be sent to manufacturing, and then it would require a fit test and possibly have to be sent back and forth for tweaks. "Now, believe it or not, we literally have an intern design the part, we print the part overnight and then we install it," Grant said. "And it only costs $2 to $3 worth of materials. It's quite useful for prototyping." Bradley Martin, a senior policy researcher at the RAND Corporation, said the Navy and Marine Corps have "come to realize that technology is moving quickly, and there is less ability to go through a long, drawn-out Dr. David Walker, right, Research and Development Portfolio director at the Office of Naval Research, moderates a Naval Research Enterprise leadership panel discussion on accelerating innovation to be first to field during the 2018 Sea-Air-Space Exposition April 10 at National Harbor, Md.
