Second in a series on the Maritime Security Advisor role created by the SHIPS for America Act.
In our last piece, we made the institutional case for why the Maritime Security Advisor role matters: a new Executive Office of the President post, chairing a Maritime Security Board with authority spanning Defense, Commerce, State, and the Coast Guard—the closest thing American sea power has ever had to a single point of accountability [1]. That piece deliberately named no candidate. This one does.
We believe Captain Brent Sadler (U.S. Navy, Retired) is the right person for this role. Before laying out why, we want to address something directly rather than let it surface as a discovery later.
He Didn’t Just Study This Problem. He Proposed the Solution.
Sadler is a Senior Research Fellow at the Heritage Foundation’s Allison Center for National Security. In a July 2025 report, “Reviving America’s Maritime Strength: Comprehensive by Necessity,” he wrote the recommendation that a Maritime Security Advisor be named—co-equal to the National Security Advisor and the Director of the National Economic Council—and argued the President “should not wait” for legislation to make it happen [2].
That means the case we’re making here isn’t “a qualified person happens to be available.” It’s narrower and more direct: the person who designed this office is also, in our view, the person suited to run it. We think that’s a strength worth stating plainly, not a coincidence to talk around. Anyone can point to a resume. Few people can point to the institutional argument for the job itself, in their own name, a year before the position existed in statute.
The Rest of the Case
Set the authorship point aside, and the conventional qualifications are still substantial. Sadler was nominated by the White House for MARAD Administrator in March 2025—a nomination later redirected to another candidate, but one that means the hardest part of any new appointment, a completed White House vetting process, is largely already behind him [3].
His career built the cross-agency fluency this specific role demands: 26 years in the Navy, including operational tours as a nuclear submariner and service as a military diplomat in the Indo-Pacific helping direct billions in regional defense funding under the rebalance initiative [3]. That is not a resume built around one narrow lane of maritime policy. It’s built around coordinating defense, diplomatic, and industrial priorities simultaneously—precisely what the Maritime Security Board exists to do.
It’s also not a case he’s making for the first time under pressure. Sadler is the author of two books laying out this same argument at length: U.S. Naval Power in the 21st Century: A New Strategy for Facing the Chinese and Russian Threat (2023 Naval Institute Press Author of the Year, National Security Book Award finalist), and the more recent Naval Power in Action: Seizing the Initiative in the New Cold War with China [5]. He has also testified before Congress, including before the House Foreign Affairs Committee [6]. Between the books, the Heritage report, and his record of testimony, this is a case he has been building in public, consistently, for years—not a position adopted for the occasion.
The Maritime Security Advisor isn’t a research fellowship. It’s an execution role. The strongest evidence someone can do it isn’t that they’ve written about the problem—it’s that they’ve already been trusted to act on it, at exactly this altitude, before.
Where This Stands Right Now
The FY27 NDAA, which carries the SHIPS Act’s core provisions, remains stalled in the Senate as of this writing [4]. As we noted in our last piece, that’s not actually a reason to wait: Sadler’s own 2025 report argued the President could name this Advisor today, tied to the existing April 2025 executive order on maritime dominance, without Congress acting at all [2]. If that argument was right then, it’s right now—a stalled bill doesn’t change who should hold the chair once it exists, whether that happens by statute or by executive action.
What We’re Asking
We’re not asking for a formal nomination process to be short-circuited, and we’re not claiming inside knowledge of how this decision will be made. We’re making a public case, on the merits, for a specific person—because we think the public argument matters as much as the private one, and because decisions like this benefit from being made in the open rather than settled quietly.
If you agree, add your name. We’ll be sharing the count as it grows, and using it to make the case directly to the people who can act on it.
