America is good at throwing away useful tools when times get easy. The latest example? Seaplanes. A recent Task & Purpose piece makes the sensible, even obvious, case: the U.S. should stop pretending oceans are easy to tame with only runways and big ships. Buying or partnering for a modern flying boat—like Japan’s ShinMaywa US‑2—would give the services a low-cost, high-utility option for Indo‑Pacific logistics, search and rescue, and disaster relief. It’s clever. It’s practical. And yes, it would annoy anyone who likes pretending logistics magically fix themselves.
Why seaplanes matter for Indo‑Pacific logistics
The Pacific is mostly water. Our doctrine recognizes that—Expeditionary Advanced Base Operations and Multi‑Domain Operations both depend on moving supplies to small, dispersed teams without relying on big, fixed airfields. A seaplane can land in a lagoon, a bay, or a large river and take off again. That’s not romanticism; it’s practical reach. The US‑2 reportedly has long range, short water takeoff needs, and the ability to operate in rougher seas than old flying boats. That means fewer headaches moving fuel, medevac patients, or inserting resupply to forward teams when runways are shot up or don’t exist.
The ShinMaywa US‑2 is ready-made—but not without caveats
Task & Purpose points to the ShinMaywa US‑2 as a ready candidate, and there’s a reason for that: Japan keeps building them, and the company has talked about exports. The US‑2’s numbers—long range, modest cruise speed, short water takeoff and landing, and even slow-flight control tricks—make it useful for search and rescue and humanitarian missions as well as military logistics. Other countries in the region are looking at amphibians too. India has been asking about leasing amphibious planes and China is producing its own AG600. If we don’t take this seriously, our partners and competitors will set the terms for operations in the Pacific—and that’s a bad place to play catch-up.
Don’t fall for the “seaplanes are fragile museum pieces” line
Yes, flying boats are slower and bigger targets than stealth fighters. Yes, they would be vulnerable in high‑end fights without control of the air. These are real problems. But they are not show-stoppers. Survivability can be managed with tactics, escorts, unmanned logistics, and basing choices. More importantly, buying a handful of amphibians is not about tilting alone at carrier groups; it’s about filling gaps in peacetime and gray-zone operations, humanitarian response, and the messy logistics that win wars. We retired the last U.S. flying boats decades ago and threw away the training pipeline and spare parts. Rebuilding that is doable and worth a sober cost-benefit check—not a reflexive dismissal.
What Washington needs to do next
Congress already nudged the Pentagon to study seaplanes. That study should not be a paper tiger. The Department of Defense must deliver a clear, unvarnished analysis: mission lists, cost estimates, survivability modeling, and industrial‑base options (buy off the shelf, co‑produce with a partner like Japan, or develop a new design). War Secretary Pete Hegseth and President Trump should give this a fair hearing. If we want supply lines that survive the first salvo, we need to fund options that don’t vanish when the runway does. Buying a few US‑2s or starting a pilot program would be cheap insurance compared with losing an island or a brigade because we refused to think beyond concrete runways. Let’s stop pretending the Navy and Air Force can do everything from carriers and bases alone—sometimes a big, ugly, reliable seaplane is exactly the kind of problem solver we need.
