  • As private-sector investment in defense-technology research rises, the Navy’s chief science office is refocusing its efforts on areas that companies are ignoring, but that will be relevant 15 years into the future, the head of the Office of Naval Research says.

    “It's our goal to actually help folks see not just what the Navy needs now, but what the Navy will need in the next three” future years defense program, or FYDP, cycles, Rachel Riley, who heads the office, told the audience at the Sea-Air-Space symposium Tuesday. “What we're trying to identify is: what are the things that industry cannot or will not solve?” 

    These include new undersea technologies and novel forms of power and energy.cIt also means artificial intelligence that delivers answers in a way that is transparent and understandable to humans, and especially commanders.

    Riley’s priorities reflect the Trump administration’s decision to spend less on military-led basic scientific research—an ONR specialty—and more on applied research.

    “We have roughly $3 billion a year. That's a lot as a taxpayer; as an innovation leader like you, you can do a lot with it, but maybe not as much as you might want to. And so what we're trying to identify is, what are the things that industry cannot or will not solve,” Riley told the audience.

    In the past, Riley said, ONR hasn’t done a good job of surveying private-sector research so it can focus its own efforts on challenges unlikely to be solved for the commercial market. 

    “Interestingly enough, a reaction that I get a lot [from ONR colleagues] is, ‘We just don't know what industry will do.’ If there's a large addressable market, if there's dual use, if there's a short time in terms of from flash to bang, then that's really right for investment” by the private sector, she said. 

    Correctly choosing ONR’s projects, she said, “requires us to be a little humbler in terms of—you know, some of the things that historically have been only our problems aren't anymore. I think that's a success story.”

    One of those areas is explainable AI. While the cost of a false positive, or “hallucination” in AI-speak, might be low in a commercial setting, the consequences can be far higher in military operations. A growing body of research indicates that such errors are inescapable in commercial large language models, so the military needs a new approach—one that has no immediate market need.

    “If you are trusting an autonomous system with American lives, then you need to make sure that you have full confidence in what that does. And a lot of times that requires looking inside the black box. That's actually harder from a technical perspective and requires more work up front,” Riley said. “How do we invest in encouraging people—don't just train this thing and say, ‘It's a great idea.’ Let's actually be able to give the operator confidence.”

    The office plans to launch a series of “innovation-to-industry days” to “influence industry [internal research and development or] IRAD investments, to help educate our folks about capabilities that may be more mature in industry than we know today, and also to help you all see the things that may be dual use coming down the pike.”

    ONR’s Naval Research Laboratory, led by Capt. Randy Cruz, is also refocusing on research areas that the commercial sector is ignoring.

    “Of our one and a half billion dollars of revolving funds, about 80 percent of it is someone telling us what to do, as in ‘I need you to solve this problem,’” Cruz told the Sea-Air-Space audience on Monday. “Another 20 percent roughly is our researchers coming up with these ideas,” based on post-deployment reports and market research trends.

    That process has led to new programs like the Mission Robotics Vehicle, a satellite with arms to repair other satellites. NRL, working with Northrop Grumman, will launch the satellite in July. Cruz called it a tow-truck for satellites. It’s an area that private space companies have ignored, since their business model is based on more launches to put more satellites in orbit, not fixing old ones. “The cost of these exquisite systems is unbearable, so the idea of servicing them… is looking very, very appealing.”

  • Navy Secretary John Phelan, the service’s top civilian leader, is leaving his role, the Pentagon announced Wednesday. His departure was announced as the Navy takes part in an unprecedented blockade of Iranian ports, and the day after Phelan spoke at the nation’s largest naval-themed conference.

    “Secretary of the Navy John C. Phelan is departing the administration, effective immediately,” Sean Parnell, the chief Pentagon spokesman, said in a post on X. “On behalf of the Secretary of War and Deputy Secretary of War, we are grateful to Secretary Phelan for his service to the Department and the United States Navy. We wish him well in his future endeavors.”

    Phelan, a businessman with no prior naval experience, was in the role for just over a year. He spoke to reporters on Tuesday during the Navy League’s Sea-Air-Space conference, as the service unveiled its $378 billion budget proposal. The request focuses on buying 18 battle force ships and 16 auxiliary ships as part of the administration’s “Golden Fleet” initiative.

    “This is a strategy-driven budget,” Phelan said in a Tuesday press release. “It's not about business as usual—it's about making generational investments in real, usable capability for our warfighters."

    The White House and a Pentagon spokesman did not immediately return a request for comment asking for more details about Phelan’s departure. 

    It comes weeks after Defense Secretary Pete Hegseth pushed Army Chief of Staff Gen. Randy George to retire. One defense insider told Defense One the Navy secretary’s vision for the service and personality clashed with other Pentagon officials.

    “Long-rumored but still, wow,” the source said. “Insiders did not see him a minute past July 4 and even this late was borrowed time.”

    Mark Montgomery, a retired Navy rear admiral and a senior fellow at the Foundation for Defense of Democracies, said Phelan did not leave a strong legacy as a service secretary and specifically criticized his battleship and frigate initiatives.

    “Not knowing why he left, I’m careful to not be too critical. But I would just tell you he was not a successful service secretary,” Montgomery said. “Way too many of his good ideas haven’t developed enough and his bad ideas are hurting the force.”

    In early February, CNN first reported that Phelan had flown on a plane from London to New York with convicted sex offender Jeffery Epstein in 2006. A copy of the flight manifest, which shows six redacted names of other passengers, was reviewed by Defense One

  • Plans to field a next-generation replacement Air Force tanker are being pushed aside in the latest budget request as the service looks to invest in upgrades and new technologies for existing refueling systems instead. 

    Funding for the Next-Generation Air Refueling System, or NGAS, was zeroed out in the 2027 budget request. The prior year, the initiative to develop a future refueling aircraft received nearly $12 million. 

    Instead, the service requested $13 million under a new budget line titled “Advanced Tanker Systems,” service officials told reporters Tuesday during a Pentagon budget briefing. That money, if approved, will go to “mission systems as opposed to platform,” while analysis on a future replacement aircraft continues. The funds would come directly through the baseline budget, not additional supplemental funding from Congress.

    “We are shifting to what's called advanced tanker systems,” Maj. Gen. Verdugo, the Air Force’s deputy assistant budget secretary said. “It’s looking to offer more options than just NGAS, and to make sure that our future advanced tanker systems are more resilient and can operate in contested environments.”

    Some defense experts fear the service’s delayed push for a tanker replacement will create a future imbalance between crucial support aircraft and the service’s growing combat fleets. The Air Force’s latest budget request includes asks for 24 F-15EX and 38 F-35 jets as well as a multi-billion investment for development and production of the next-generation F-47 fighter and B-21 bomber. Though the service is also requesting funds to purchase 15 KC-46s, it plans to retire around 20 of its aging KC-135 tankers—which are already taking heavy battle damage in the Iran war. 

    Recent calls for a new tanker began in early 2023, but little progress has been made to make the next-generation replacement a reality. One former military official said having a fleet of lethal combat aircraft is important, but not having a modern tanker to support them could be detrimental to a future fight.

    “When you don't make it a priority, this is as fast as you can go,” the former military official said. “When, when bombers and fighters are the priority, and I'm not saying that they shouldn't be, and that you don't understand how the mobility can fit into the programming strategy, this is what happens. You just get eked along.”

    Current and former air mobility leaders have raised concern in recent weeks over the aging refueling fleet and have also called for much-needed upgrades to the service’s legacy KC-135s after six airmen died last month in a tanker crash during Operation Epic Fury. 

    “I cannot have a 90-year-old tanker refueling a B-21, and if you do the math, as we reach the end of programs for things, that’s the reality,” Lt. Gen. Reba Sonkiss, the interim head of Air Mobility Command, told reporters in February.

    Air Mobility Command leaders have warned that the service’s mobility fleet lacks the key communications and connectivity upgrades needed for full awareness of enemy and friendly aircraft in chaotic combat zones. Those upgrades are one of the initiatives being looked at under the Advanced Tanker Systems budget line, a service spokesperson told Defense One.

    “Overall, the Air Force continues to explore options based on NGAS Analysis of Alternatives that will enable resilience and persistence of aerial refueling in a future, highly contested conflict,” an Air Force spokesperson said. “This includes pursuit of platform-agnostic capabilities focusing on connectivity, battlespace awareness, and survivability.”

  • The Navy is getting its turn this year to get an independent assessment on its future with a congressionally-mandated commission on its future. While the commission’s mandate is wide, there’s one overarching question the group will need to answer: What can Congress do to support the aging fleet as the defense industrial base works to catch up to demand?

    Though the service’s ideal ship count is a moving target, the real problem is that too few of the ships it does have are actually able to get underway, commissioner Trip Barber, chief analyst for Systems Planning and Analysis, Inc., said Wednesday at the Navy League’s Sea-Air-Space conference.

    “The problem is that there are so many demands and there's so little Navy to meet them,” Barber said. “The Navy we have today is smaller than the demand and the level of pressure on the force, as a result, is unsustainable.”

    Just over the past year, Navy ships have been engaged in combat operations in the Red Sea, the Caribbean and now in the Persian Gulf, putting strain on the service’s notoriously overextended carrier strike and amphibious ready groups.

    “Part of the reason the Navy is too small is that the deployable part of the Navy is too small,” Barber said. “Too much of it is stuck in maintenance. It's not being recapitalized at the rate at which it's wearing out.”

    The service is in the midst of a plan to streamline its maintenance periods and has bumped its request for shipbuilding funds up 50 percent this year, but those are longer-term plans that will take years to pay dividends as the fleet continues a relentless deployment schedule.

    “The Navy is as busy as I’ve ever seen it in my career, just as an observer,” said commissioner Mackenzie Eaglen, a senior fellow at the American Enterprise Institute.  “And it's historically way too small.”

    It’s going to get smaller, the commissioners said, while the defense industrial base ramps up to meet the service’s demand. 

    “How do we cover that risk?” Barber said. “In the interim, we've been looking at unmanned options, because that's really the only way we can get more capability out there.”

    But the Navy needs a clear unmanned strategy, he added.

    “So if unmanned is key to the near-term, because we can't build enough large ships fast enough to meet the capability needs, we're going to have to use smaller things that are unmanned,” he said. “How are we going to focus and manage that? And I don't think the Navy currently is doing a very coherent job of doing that.”

    If remote and autonomous systems are not only the bridge to a higher ship count, but the future of warfare, the Navy needs to start thinking about what that means beyond the capabilities they could bring, said commissioner Tommy Ross, head of global public policy at Alteryx, Inc. 

    “We need to think about not just the equipment, not just the platform, but also the people that are needed to support,” he said. “Even though they're uncrewed, there's going to be a lot of people that support these systems.”

    Details like where they be home-ported and what they need in terms of maintenance facilities have yet to be worked out, he said. 

    “I can go on, but I worry that … we’re much further ahead in our thinking about the technology than we are thinking about all those other elements,” Ross said. “So I think that's an area that I hope the commission will dig into.”

    And though the Navy and presidential administrations have often focused on ship count, Barber said it’s a meaningless number if it isn’t the right balance of ships, from carriers to amphibs to submarines.

    “Each of them has a number that makes sense, and having too much of one doesn't compensate for having too few another. We need to have a set of numbers that, in the aggregate, describe what the Navy needs to be able to do,” he said. “And whatever they happen to add up to at the bottom line does not matter, because you have to hit each one of those to have the right Navy, with the right capability.”
