    The US Navy wants to find ships to kill using aerial drones launched from submarines

    By: David B. Larter WASHINGTON – The name of the game in the Pacific is stand-off range. But with longer range torpedoes and anti-ship missiles in the arsenal, submariners are looking to a new domain to help them extend their deadly reach: The air. In an October request for information, Naval Sea Systems Command's Submarine Combat and Weapons Control Program Office asked industry for input into a “Submarine-Launched Unmanned Aerial System,” or SLUAS, currently in development. The Navy has been interested in sub-launched drones for some time and has been testing prototypes, but the RFI shows the service is getting serious about the idea as it adds longer-range torpedoes and anti-ship cruise missiles to the arsenal of its attack submarines. The idea for the SLUAS is an ambitious one. The drone would launch from a submerged submarine out of a 3-inch ejector tube used for sonobuoys, flares and countermeasures among other things. The battery-operated UAS would then deploy its wings and operate for an hour, well beyond the range visible from just the low-in-the-water periscope. Additionally, the UAS should have an “electro-optic capability with reliable target solution analysis,” the RFI said, adding that it should be able to “operate at ranges out to the line-of-sight radio horizon, and use a variable bandwidth encrypted datalink with at least 256-bit encryption strength. The drone should also have a degree of autonomy and “include the ability to operate in an emission-controlled environment and operate without constant radio communication links.” “Every submarine has a 3-inch launcher, so in theory, every submarine could operate with UASs,” said Bryan Clark, a retired submarine officer and senior fellow with The Hudson Institute. “The idea is that you would be about the size of a sonobuoy — it could be pretty long — and you'd put it inside a canister. Then you launch this in a canister, it floats to the surface and the USA deploys from there. “And from there it can either connect up with the submarine or it could connect with another unit, and it gives you the ability to have over-the-horizon surveillance.” “The demonstrations have been pretty successful,” Clark added. The responses to the RFI were due in November. https://www.defensenews.com/naval/2020/12/07/the-us-navy-wants-to-find-ships-to-kill-using-aerial-drones-launched-from-submarines/

    Silicon Valley investors to DoD: Dual-use tech is a bad strategy

    By: Jill Aitoro SIMI VALLEY, Calif. — Dual-use technology — that is, tech that can be adapted from the commercial market to serve the needs of the military — is core to the U.S. Department of Defense's innovation strategy. But those willing to put money toward big ideas argue it's the wrong approach. “In terms of how to build a startup and how to scale really fast, you can't have two missions,” said Katherine Boyle, an investor with venture capital firm General Catalyst, during a Defense News roundtable in California. “You can't be a 10-person startup saying: ‘OK, we're going to sell to the DoD, but we're also going to sell to these commercial customers, and it's just going to work out magically.'" For the second year in a row, Defense News hosted the roundtable to dig into Pentagon's efforts to engage with the commercial tech community — this year digging into the challenges and opportunities that come with investment in defense development. To the Pentagon, dual-use technology offers an attractive means of drawing new players into the military fold, while also leveraging the more rapid development that happens on the commercial side. But the model is evolving, said Mike Madsen, director of strategic engagement with the government's Silicon Valley outreach hub Defense Innovation Unit. With DoD, “it takes two years to get to a ‘yes,' when a lot of companies need a ‘no' in 30 days because they don't have the capital,” he said. “So we flipped it. Now we start with the DoD problem set and take it out to industry. And we've lowered a lot of the barriers to entry — we negotiate [intellectual property] for each contract, we negotiate auditability, we move quickly. We look to award prototype contracts in 60 to 90 days.” The approach also attempts to rebalance the gradual shift in research and development investments in the last couple of decades. As noted by Tom Foldesi, DIU's commercial engagement director, one-third of worldwide R&D was tied to the Department of Defense in the 1960s. That percentage has since tanked to 3.7 percent. A separate business line allows R&D to continue to iterate to the next generation of technology so the DoD can “go back to the cookie jar” and tap into the technology to solve future problems, Foldesi said. But to Trey Stephens, a partner at venture capital firm Founders Fund and a co-founder and executive chairman of Anduril Industries, the model ensures the large, traditional defense contractors continue to dominate as the small businesses only “dabble in defense.” It also means the DoD won't bear sole responsibility for the economic growth of these small tech startups. “Where I'm not on board is where a traditional defense company is being asked by the government to integrate dual-use capabilities as a way to prevent that oligopoly from being shaken,” he said. “We have to break this oligopoly. We can only do it if we find companies that are willing to own their responsibility for execution on programs.” To be clear, Stephens acknowledged cases where commercial technology companies can be primes. Lawsuit aside, he's “on board” with awarding the Joint Enterprise Defense Infrastructure contract to a commercial business — Microsoft — “because the capability is similar enough.” Microsoft was awarded the Pentagon's JEDI cloud contract, but Amazon Web Services has asked a federal court to block the department and the company from beginning work on the project, according to a Jan. 13 court filing. In terms of new capabilities, Stephens advocates for turning the model on its ear: Enable startups to first development a solution to a problem faced within the DoD, then turn that around and sell it to commercial industries. “The commercial industry is oftentimes looking to the government for aspirational solutions to some of its hardest problems, whereas the inverse doesn't really work,” he said. General Catalyst, which counts The Honest Company, Snapchat and Airbnb among its portfolio of companies, has invested in two pure-play defense companies: Anduril, and Palo Alto machine-learning company Vannevar Labs. The latter is developing a product that would bring natural language-processing technologies to support counterterrorism missions. “We actually think this is a better model,” Boyle said. “If you're scaling rapidly, you have to be very focused on your customer set. And if you're going to have to sacrifice a customer, even if you're a multibillion-dollar company, you're going to sacrifice the one who's moving the slowest. And that's usually the government.” https://www.c4isrnet.com/smr/cultural-clash/2020/01/30/silicon-valley-investors-to-dod-dual-use-tech-is-a-bad-strategy/
