Most people can pick a Chinook out of a lineup even if they couldn’t name another helicopter on Earth. It’s the big twin-rotor machine shaped like a flying banana, it’s been in service since the 1960s, and the Army still hasn’t found anything it likes better for hauling heavy loads into ugly places. The special operations version, the MH-47G, belongs to the 160th Special Operations Aviation Regiment, the Night Stalkers, and it’s about as serious as American rotorcraft gets. Which is why it caught my eye that one of them just landed on a barge with nobody on it.<\/p>\n
Sea Machines Robotics, a Boston company that builds autonomy systems for ships, announced the flight in late September. An MH-47G from the 160th SOAR set down on one of the company’s uncrewed, self-driving barges and was replenished right there on deck. Naval News<\/a> carried the story on September 23 and called it the first time the public has been told about a US helicopter landing on and resupplying from this kind of vessel while it was running autonomously.<\/p>\n The announcement itself was a LinkedIn post, which is a pretty low-key way to reveal something this strange. The company hasn’t said where or when the flight happened. The barge’s dimensions and the number of landings didn’t make the post either, and that’s a lot to leave out of an announcement about parking a helicopter on a robot barge. What we do have is a photo of a very large aircraft sitting on a very empty deck.<\/p>\n And “very large” is underselling it.<\/p>\n The MH-47G runs just about 99 feet long with its rotors turning, each of those two rotors spans 60 feet, and the aircraft can lift off at a maximum gross weight of 54,000 pounds. Frankly, that’s a lot of helicopter to trust to a flat steel deck that’s holding position all by itself.<\/p>\n The military calls this kind of setup a FARP, a forward arming and refueling point. It’s basically a gas station with an ammo counter that you plant close to the fight so aircraft don’t have to fly all the way home between missions. A FARP normally sits on land, and somebody has to secure that patch of ground, truck in the fuel, and defend the whole operation for as long as it’s there.<\/p>\n Put the FARP on a barge and you can park it anywhere there’s water. Put it on a barge with no crew and nobody has to live on a slow, flat, extremely visible target. If an enemy finds the barge and sinks it, you’ve lost a barge and some fuel, and nobody has to write a letter home.<\/p>\n You may be thinking the MH-47G can already refuel in midair, and you’d be right. It has a probe for exactly that. But aerial tankers are scarce, expensive to keep on station, and they can’t hand you ammunition or cargo. A deck you can actually land on gives you rearming, resupply, and somewhere to set the aircraft down if a warning light comes on over open water. As far as I can tell, that last one alone justifies the concept.<\/p>\n None of this came out of nowhere. In October 2020, the Defense Innovation Unit, which is basically the Pentagon’s office for buying commercial tech quickly, hired Sea Machines to convert ordinary commercial barges into exactly that: a floating pit stop, as Marine Log<\/a> reported at the time. The program is called the Amphibious Maritime Projection Platform, and the barges are meant to serve as FARPs for military aircraft.<\/p>\n The clever part is that Sea Machines doesn’t build the barges. It builds a kit, called the SM300, that bolts autonomy onto vessels that already exist. The 2020 contract teamed the company with Foss Maritime for the naval architecture, plus shipbuilder Huntington Ingalls and helicopter maker Bell Flight. By August 2021 the work had moved into a second phase, with $3.1 million going toward a full-scale ocean-going replenishment platform, according to a Sea Machines release from back then.<\/p>\n Then the whole thing went quiet for about five years. Naval News says the company kept at it with the Defense Department, away from public view, which, for a special operations logistics program, is pretty much how you’d expect it to go. Per Naval News, the kit has since been demoed on everything from barges big enough to take a Chinook down to boats roughly 20 to 30 feet long.<\/p>\n Two weeks before the Chinook photos surfaced, this had already turned into a real acquisition. On September 8, Sea Machines announced a five-year indefinite delivery, indefinite quantity contract to get its SM300-SP autonomy kits into the hands of US Special Operations Forces, as Army Recognition<\/a> reported. An IDIQ basically means the government opens an account and orders kits as it needs them instead of committing to a number up front.<\/p>\n The pitch is the same idea pushed further. The kits go on “vessels of opportunity,” which is defense speak for whatever boat happens to be around. A deployed team could take a commercial craft or a partner force’s boat, install the package, and have an uncrewed vessel running surveillance or hauling supplies. The company hasn’t disclosed a dollar ceiling for the deal. Army Recognition noted the announcement leaves out the planned purchase volume too.<\/p>\n We’ve been watching this same logistics problem get solved one piece at a time. A 38-foot drone boat took on fuel through a probe and basket<\/a> at sea, because an uncrewed boat that can’t top off has to come home, and coming home is what these programs are trying to eliminate. There’s even a whole job built around the technician who has to be the last person to step off<\/a> before a drone boat leaves. Refueling and rearming are arguably the least glamorous corner of the uncrewed fleet, and from the looks of things, they’re where the actual money is going.<\/p>\n Sea Machines says its barges can replenish surface ships and shore positions along with helicopters, and its five-year special operations deal landed on September 8, 2026, fifteen days before the Chinook pictures went public. For a program that spent half a decade out of sight, that’s a pretty loud September.<\/p>\n","protected":false},"excerpt":{"rendered":" Most people can pick a Chinook out of a lineup even if they couldn’t name another helicopter on Earth.

The Pentagon has been building toward this since 2020<\/h2>\n
And special operations already signed up for the kits<\/h2>\n
