I would also say that space tugs would have oversized powerplants, so as a hero ship, they could add heavier shields or weapons than would be expected for a vessel of that size.

[@timeforgottenprince8271]

I'm imagining a scene where a group has to move a gigantic fortress bristling with weapons so that it can get into position to destroy its enemy, but can't do so on its own, so it has a tug pulling it while all weapons on the fortress are firing at all of the enemies around it.

[@Nostripe361]

I could also see tugs being used to move small debris in an asteroid field. Asteroid fields are really poorly portrayed in sci fi though. An asteroid field would be a cool place to have a battle if your ships were running at high impulse though

The sci-fi story I'm writing actually introduces the hero ship for the first time while in port. Its an old cargo ship that has been made obsolete by larger and newer cargo vessels, so now it has basically specialized in delivering luxury goods in record times in order to remain competitive.

[@IN-tm8mw]

@@twandepan I got the idea by combining Startrek with a game called Suikoden. I wanted the ship to start off relativity empty but fill up with shops and crewmen as the plot advances. This way, each "Guest" could be potentially a new friend or foe.

I love the idea that the Millennium Falcon is a kind of barge tug, because it explains so much that otherwise doesn't make sense. It's a small ship with massively overpowered engines designed to push huge pallets of freight around the galaxy. Now that is something you could turn into a speedy blockade runner while making it continue to look like a tramp "freighter" (really a freight tug).

[@komo6103]

You know what, I really like this idea. So many hero ships are either small freighters or ex-military, so one that's a tug is pretty neat. Imagine a small ship, with a pair of small high-efficiency engines rigged beside the huge main thruster that's like 50% the entire thing. The crew goes around doing jobs for various organizations to salvage ships and clean up convoy lanes, while doing some off the book jobs on the sides. If there's an active conflict in the area that they can operate around, all the better. Imagine all the stories you can tell without even getting into stuff that's personal to the crew!

[@Halo1Buff]

The Salvage Corvettes and Resource Harvesters of the Homeworld games fit in here perfectly and deserved a mention. Several missions use them as integral to the plot.

[@rohanhalle580]

Also for their shocking combat effectiveness. What's that, an attack fleet? It's mine now te he he.

[@winterscrescendo]

If we're looking at Homeworld, the Junkyard Dog needs a mention. They made a tug something to be feared. Another example from videogames could be the Trains from Freelancer. They're just a tug with a pair of engines hanging out at the sides and an attach point at the back for cargo units. As the name implies, you'd have a long train of cargo units with a single tug at the front used to move bulk cargos around in a system. Their appearance was reflected in gameplay as well - instead of destroying the tug itself, you could smash the cargo units it was pulling to loot them without killing the crew. Edit to add: Just remembered another one from Homeworld 2 - the Progenitor Movers. The 'hero' fleet didn't have a dedicated tug ship anymore, but their mining ships had small multi-purpose arms that could be used for repair work or pulling other ships around.

[@tba113]

Given how rarely they're given as examples, Spacedock must have to pay a fee or something for each mention of a ship or concept used in Homeworld.

[@Uzarran]

The Star Trek scenes I never skip.

[@Imperial_Lizardgirl]

Mine would be, the ones similar to 1979 movie, mysterious and spooky. With semi/pseudo realistic designed ships.

[@ParanoidMarvinMk2]

An interesting take on this is in the Honorverse. Since any large vessel that can get up to a decent speed is a potential weapon vs. stations or planets, and the universe has some mind control shenanigans going on, ships have to power down their engines and wait for a tug WAY out. The tugs have dual pilots and the pilots are very highly cleared and screened.

[@f38stingray]

This was the kind of purpose I was thinking of. On a related note, tugs might be helpful since engine exhaust (or even thruster exhaust) could damage parts of a station or docking craft. The space shuttle, for example, had to select specific thruster groups to dock with the ISS. Tugs could offer a way to temporarily add thruster groups in strategic locations to spacecraft in areas where they avoid damage. It could be interesting to see how different cultures might circumvent the need for tugs in a universe like that.

[@ParanoidMarvinMk2]

@@f38stingray In the case of the Honorverse, there is the complication that the main engines of most ships are powerful gravity warping devices (gravity manipulation being the main applied phlebotinum of the Honorverse) that would shred any other ship within a range of a few (dozen maybe? EDIT: looked it up, hundreds for large ships) kilometres of the main ship. Ships have reaction thrusters as backups of course, but their main drives would destroy the space station (of course invoked in one book where the heroes use the gravity drive of a shuttle to destroy a battlecruiser). For this trope of space tugs, the idea that while ships COULD dock on their own, they would have to use secondary drive systems which might be weak, etc., would be super relevant. A writer could then use this as a plot point. A random dramatic idea I just had while writing this might be something like the Honorverse example, where bringing up the main drive would destroy the station and kill your friends onboard, but might be necessary to get going in time to stop the ship on a kamikaze run towards the main planet. Of course, this is kind of a forced sacrifice and an engineering/planning idiot ball a la Cold Equations. You'd hope in your universe people would be smart enough to have some sort of rapid (but dangerous and semi-destructive) emergency undock and "push clear" system, or just picket ships ready to deal with such things.

[@crazyterran11]

@@ParanoidMarvinMk2 The Honorverse has tugs to move around things around the planets too; in addition to pulling ships to the scrappers and occasionally things out of the shipyard (the ones we see get out are getting out on reaction thrusters, like the second Fearless and the Nike if I remember right) we see the perspective of a tug during the destruction of Hephaestus station where the tugs turn on their own wedges and use it to intercept large pieces of debris from falling onto Landing and other cities.

[@JWQweqOPDH]

I assume you mean they must come to a stop long before reaching their destination. You described this as "turning their engine off", but it would be the opposite, they'd have to turn their engine on full throttle to decelerate. Without drag, either the whole of cruise is zero thrust for efficiency, or the entire second half of cruise is decelerating (first half accelerating)(perhaps 1G for comfort). It takes as much effort and time to safely slow down as it does to speed up. An interstellar ship could accelerate to relativistic using laser sails over a century, still be a small fraction of the way to its destination, and be without thrust the rest of the way, and wipeout life on the planet it strikes, even though it had been essentially derelict for a millennia.

[@ParanoidMarvinMk2]

@@JWQweqOPDH This was specific to a particular fictional universe, as I said, where the main engines of ships are capable of destroying everything within a hundred kilometers or so, because reasons. They are also very powerful, so ships generally travel at high speeds (0.6-0.8c) for cruise, and can accelerate up to those speeds quickly. The point was that those cruise speeds and powerful engines give a role for tugs. If you ever read the Honorverse, you would know that David Weber is VERY VERY aware of the scale of space and the role of coasting to get somewhere.

I like the concept of an orbital tug basically being a small vessel with a very big engine whose whole purpose is to ferry cargo between the ground and orbit

[@DarthBiomech]

My setting has something similar, orbital barges. Though they're not tugs, rather they're optimize for lobbing huge amounts of cargo down and up from a gravity well, and are basically just huge platforms with powerful antigravs but not so great engines - just good enough to achieve orbital speeds once they're in space, but that's about it.

5:36 In Nebulous Fleet Command, tugs are actually one of the ships you can outfit and bring into combat. They're decently fast and maneuverable but have basically paper armor, but they can fit a pretty deadly 250mm autoloading main gun and punch up against heavier ships if you fit them with missile launchers or rocket launchers. They can also fit a fully sized reactor and act as jamming, early warning, and electronic warfare platforms.

This just reminded me of the Planetes anime, where the main job of the main cast is to clean up space debris.

Either between stations and orbital mining platforms and fabrication factories. Delivering bulk cargo to interstellar ships. You'd also have the rough and tumble subculture of space truckers/tuggers.

I was thinking of this as well.

[@thomasrdiehl]

One more for your list: The Eureka Maru from Andromeda is first introduced into the series pulling the Andromeda from a black hole. While officially designated a cargo ship, the Eureka Maru was used as a salvage ship and is probably more aptly described as a tug in actual function. At the very least, it's equipped to work as one.

[@twudotJam]

In a little sci-fi concept a friend and I have been bouncing around as part of a potential writing project, we've decided to use a Ground-to-Orbit launcher as the 'hero ship' (kind of). In the setting, most ships are built for pretty limited conditions, and many settlements and such exist on planets with higher gravity than Earth, so on most of them some variation of a 'small ship that is 90% volatile engine' is pretty common. The main one, just known as Racker, has the thrust capabilities of a ship 7-8 times it's size. The crew meant to be aboard is essentially a pilot and 5 engineers to keep the thing working as it tows vastly larger ships into space, where the larger ship can then get on it's way. I'm glad I'm not the only one who thinks the tug concept is VERY underutilized in sci-fi.

[@mervjohnson8010]

I think there's even MORE case for tugs in space than on the sea. In space there's lots satellites or other space infrastructure which needs to be placed in long term orbits. Giving each sat their own drive is costly and wasteful. A tug is basically a freighter whose cargo is on the outside.

Having a couple small, cheap, powerful ships to help with docking large craft, salvaging debris in places too tight for bigger ships, or helping large ships that have run out of fuel or power get back to a station is extremely useful. And since they're relatively cheap, losing one or two isn't a huge material setback like losing a bigger rescue vehicle would be.

[@EndoAvecDesChiffres]

The hull series of ship from star citizen and the Srv are two good exemple of what you're explaining in this video one is a freighter and the other one a tow ship

[@maurenovick]

I am so happy you actually finally did a video on this!

[@bsquaredbundles]

Star Citizen's ARGO SRV tractor beam tug ship should be in game in a few months. Very excited for that.

[@warmachine5835]

3:15 I came here because one of the things I did in KSP was create manned and unmanned 'tugs' for moving stuff around a space station, since each tug could provide more thrust to move big objects better than an RCS thruster, and by not bringing those engines with me for "the last mile" it saved payload mass. Space plane goes up, tugs unload the supply payload and attach it to the station. Or "giant interplanetary engineering section" goes up, tugs drag it to the craft and attach it since it can't maneuver on its own.

[@jacara1981]

The video of the Enterprise D saucer recovery shows tugs being used to lift it from the surface. I know from early design and story boarding for TNG they wanted to show a "tug" that would be as big as a ship, It would essentially wrap around and grab the ship. Mostly it was all structure and warp drive. This was back when Tractorbeams couldn't work at warp. However due to the same old "costs to much" they just went with glossing over and using Tractorbeams at warp.

[@thaelindarkfyre4112]

The Spaceship Hunter-Gratzner from Pitch Black is a sorta modular ship / tug where the back and the front are detachable and cargo / transport pods are carried in the middle

[@Arianoch]

Star citizen is getting a tug ship later this year. Already has a few great industrial ships like the Reclaimer salvage ship seen near the end of this video.

[@kend6232]

Great piece, I agree on the utility hero ship, an Expanse spin off would be awesome for that. Thanks for mentioning the Nostromo, its the first one I thought of, Go Tugs!

[@starpilot101]

On the topic of barges and tugs, I really love the "detachable head" concept where the majority of a ship's mass is skeleton structures for housing containers and the cockpit is the only fully capable vessel. This is a perfect main character vessel because you got the home base and the adventure ship. The cargo section has limited mobility and controls, but the cockpit section contains the hyperdrive and more powerful engines. It's not really a "barge and tug" but not a single continuous ship either.

[@davidtuttle7556]

My favorite ship class to use back in my SFB days was the Kzinti CGT battle tug variant with battle pods. It was essentially a monitor of sorts. Slow af but armed to the teeth and could take a beating.

[@Vinemaple]

As a professional mariner, I have a deep respect for all tug and towboat operators. We definitely need more working vessels, and working people, in science fiction! As a KSP player, while I don't use my RCS-powered station tugs, or my rescue and salvage vessels, very often, when I need them they are crucial, and can mean the difference between reverting/restarting and continuing. I think it's dubious to call them tugs, but what I do use a lot of are recoverable drones that deliver modules or cargo to space stations or other vessels, then de-orbit and splash down on Kerbin. It started with the need for something like the Soviet _Progres_ freighter, and now they're almost half of my launches.

[@a-blivvy-yus]

I've been playing Starsector recently, and it has a ship class called the "Ox" which is labelled as a "tug" and gives your fleet a small boost in its travel speed at the cost of very high fuel use when you use it in FTL travel. Really cool if you have the fuel supply to run it, and helps keep your bigger ships moving more like smaller ones do.

[@nobody8717]

you can have multiples of the ox to stack the speed bonus. penalties stack too, but just get another prometheus for the fleet to solve that.

[@a-blivvy-yus]

@@nobody8717 Thanks, I thought that would probably work, but never tried it!

[@DrBunnyMedicinal]

Great work as always folks, many thanks to hoojiwana and all the rest of the Spacedock crew!

[@lazulenoc6863]

I remember the tugs in Treasure Planet: Battle at Procyon. You can use them to pull around your ships, enemy ships, ally ships, ram light craft out of existence. All sorts of fun things. Mostly, you tow ships on your team so it can be repaired. Sometimes you haul a barge.

[@helmerhernes2330]

Honestly such tug vessels would be very useful for transporting space stations from star system to star system as most space stations would be difficult to store in aregular freighter and it plainly makes more sense to tug them there with an FTL tug than building them on the spot if advanced machine parts and the like are required.

[@trollsmyth]

One of your most inspiring and thought-provoking videos. Thanks!

[@bub1974]

Love this one! I've always had a special place in my heart for tugboats.

[@JPEight]

One of my favourite emergent gameplay elements of Aurora 4x is that the optimal solution to moving cargo around is with barges and tugs. This is because the sheer size of the cargo volume makes the ships take a long time to build. The other factor is that ships wear out or become outdated relatively quickly in that game, but the barges don't change much so you only need to overhaul/replace a moderate sized tug rather than an entire tanker.

[@Aederex]

That wave piercing anchor handling ship (an Ulstein SX157 apparently) is absolutely gorgeous. Might have to fire up From the Depths and try to replicate that. On a more relevant note, The Culture, one of the highest tech sci fi settings out there, has tugs. Ironically, their job is largely to help small ships get up to the speeds that only larger ships can reach normally, as top speed and acceleration in the Culture universe is pretty much entirely dependent on the shear quantity of matter you have dedicated to your engines. The fastest ships are also the largest, in the hundreds of kilometers long.

[@raf74hawk12]

Was getting worried that the Nostromo wasn't going to get a mention as the video went on. Gald I was wrong on that! I love that ship.

[@wickerbotterthewizard707]

Conventional Naval Tugs FOR towing space craft in and out of the ocean also makes a lot of sense! If you land your Acclamator, or other large buoyant spacecraft, at sea having an set of TUGS to guide and dock them makes a lot of sense. Another very useful kind of TUG in atmosphere would be the ones pulling cloud cities and large floating structures. In Science Fiction setting some of the most common barges for a tug to tow is the flying barge.

[@owenstim799]

Thunderbird 3 from the latest version of thunderbirds has a tug style feel when it's 3 arms unfold and utilises grappling lines to drag debris, other ships etc around in space

[@pauljensen5699]

Extraordinarily well thought out, and underrated video.

[@someonewithsomename]

Nice video! I'm actually developing a hard sci-fi setting around those types of spaceships. The thing that gets really weird, is that I don't think it quite works physics wise. (apology for the long read below) Tug boats and trucks/trains all have powerful engines optimised for torque. It's basically the amount of weight you can pull. And your speed and acceleration depends on how fast you can transfer your engine power to mater you are pushing against. Propellers for air ships, water vessels, wheels for ground vehicles. The faster your go, the less torque you have. And the stronger the forces you are working against become. As drag scales exponentially with higher speed. That all means that in general, you have either machines, that can haul heavy loads, or fast stuff. It is basically the thing everyone knows and takes for granted, right: hyper cars are small, slick and fast, trucks are big, slow but can pull a lot of weight. Now, if you try to create a space ship with the same mentality - slow, but powerful ship, that can pull heavy weight - you realise when you plug the numbers into formulas, that there's no difference between a truck and a hyper car in space. If your spacecraft can effectively pull a gigantic barge, it also becomes a death-trap accelerating at 20gs when it is not. Simply because there is (almost) no drag in space. And you do not have to transfer power to different matter to push against it to accelerate. You just accelerate by throwing the matter from your ship, so don't have to be concerned by friction and so on. Oh, and also the matter you are throwing from your ship - unlike air and water - is extremely fast and hot. That means, that if you do a similar manoeuvrer as the tug boat makes at 00:35, you leave a scorched hell of molten space station materials behind your ship. If that was not enough, the space engines in real life are very propellant (fuel, to simplify) hungry! Currently, you have like two options: either burn a lot of fuel really quickly and go fast (or pull a lot of weight). Or do it very effectively but barely accelerate. If you pick the first option, you have to bring with you a huge amount of propellant also, which means you are not only pushing a massive weight of some transport ship, you also add massive weight of your own tug-spacecraft, that it became. If you picked the second option, it means that it takes weeks or months for your massive space barge to dock with anything. That is why, even in the most hard sci-fi heavy settings like The Expanse, there is still some almost magical technology, like infamous Epstein drive, that is both crazy effective and super powerful. Which in theory is just a fusion torch drive, that is not beyond our scope of understanding of physics, like some Jump drive would be. But it is in a similar vein to a combustion engine, that can accelerate your car to 1000km/h, drive through the whole continent while use only like 10 litres of fuel. To conclude, it all means, that there is no space for a tugboat-like spacecraft in space (what a pun, oh my!) And in sci-fi setting, either the setting itself does not care about physical constrains (which is fine, it's a creative choice) to include day-to-day mundane technology, show how ports work and all that. Or the setting is too physically accurate and the authors understand those limitations I described above. I myself have a solution, that works for me. If you are interested, ask a question in the reply. Also, if you've read all of this, you are a legend and I applaud you! :)

[@delcox8165]

1:14 They're used constantly. You just don't notice for reasons that are twofold: It would've been a _heavy_ cost in labor, budget, or both to add in the effects causing the ship to maneuver (considering CGI was a new concept), and it would've made the shots look too "busy" when completed. Take the impulse engines, for example. They're intentionally rendered without an exhaust plume, but that doesn't mean they're inactive.

[@shagiephoto]

Have you looked at the Solar Clipper series by Nathan Lowell? It's mostly industrial hauling ships. There are small 'tractor' class ships with an officer with a crew of 8 that haul cans. There's also a barbell class ship that has bulk undiversified freight that clips on to a very large single can. And there's a number of other ships too - just those are the two most tugish... well, aside from the actual tugs (but those aren't hero ships in the story).

[@hat6885]

1:24 HE DID IT HE SAID THE THING

[@TenakuMihara]

The Starfinder tabletop RPG introduced 'Hauler' frame vessels; capable of fielding Oversized engines meant to haul things bigger than themselves, but also capable of getting a speed boost from them when unencumbered, with room for on-board maintenance expansion bays or other modifications meant for repair and rescue. I introduced a pair to the fleet my crew is a part of and named them Nomadic and Traffic. Bonus points if you know what that references.

[@nonoyobizness9090]

The hero ship in my trek fanfic is a converted heavy tug... this was super helpful. Thank you

[@k-874]

One of my favourite sci-fi spaceship ever is definitely the largely forgotten Tug-314 interstellar tug from Star Wars. Instead of using mechanical arms, it uses two massive powerful tractor beam projectors mounted on each side of the vessel. It also comes in two different flavours, the standard small variant and the large variant. The standard variant is the most commonly used around space stations and posts used to move around light cruisers and frigates, while the large version is utilized on major space ports used to move around star destroyers. Not only is this ship so damn gorgeous, it also serves several other roles such as search and rescue(literally saved R2-D2 and the universe as a result), firefighting, and salvage operations.

[@chase-2-2]

Pretty much one of the first things i always build once i get to building a multi module space station in KSP is an orbital tug. A tiny automated craft with a powerfull monopropellant thruster and a bunch of rcs and gyros. This thing is super usefull to move around cargo or station modules that, while having their own rcs thrusters, may not have their own monoprop tanks, control systems or are just too weak to easily rearrange.

[@Tuning3434]

Yes. Whenever I have some excess dV in my ships, my munar transfer stage quickly becomes equipped with at least a docking port so it can function for a while as an orbital tug, potentially upgraded with a grapping claw in order to do intercept missions. A bit later I add a nuclear tug to handle Kerbin / Minmus and Mun transfers + a refueling station on Minmus. That and a dedicated nuclear personal shuttle allows me simplify crewed launches by SSTO's into LKO instead.

[@slothysoap4589]

Hanving lots of smaller engine drones for salvage and towing makes a lot of sense. Most ships won't have towing in mind for long trips, so we won't have the hard point needed for the tug ship to get a hold without damaging it. Thing towing a car that doesn’t have a tow hitch. If you wrap a rope around the hood or something, something is gonna get damaged. But if you spread the force across the ship's surface with lots of smaller drones, you can exert the same total force to the ship, while applying not as much to each point of contact.

[@random9q]

The Homeworld series also featured tugs. They were a significant tactical option, one which was sometimes mandatory for several campaign missions, and were a great way to put your opponent on their back foot if you could execute a grab of a major capital ship. Then there’s the “junkyard dog”. Which is a mission-specific _enemy_ tug, one that does what you normally try to do with your own, but far more powerful. It takes any of your capital ships on its own and hauls them away in order to reprogram them as part of its own stockpiled, salvaged fleet. The mere _capability_ of being able to drag other larger things around, including _unwilling_ other larger things (if you piled onto them with several tugs), could make for great plot pivots. And it has. Though it’s… not actually a tug… the Deathstar being able to execute massive long-range tractor beams made it… a tug. A really, really awkward pull-things-in-to-devour-them kind of tug (think of it like a really, really sluggish Pac-Man). Finally, if you’re showing a tractor-trailer arrangement as a tug, there’s a closer analogy: a terminal tractor. These things have an even smaller profile than most tractors, often only one seat and an accordingly smaller cab, and a much faster hitch that can engage and disengage from a trailer comparatively rapidly. They’re used for moving trailers about in a trailer yard, including both docking and undocking them from loading bays and just plain shuffling things around in the yard as needed. Those are your real “tugboat”-style workhorses. Fewer in number, but where they’re in use they’re way, way busier.

[@barghest2367]

My hero ship is a tug! The sci-fantasy novel I've been brainstorming for years uses a decommissioned fleet tug as the heroes' HQ. The Parhelion fits into the story's themes in that it isn't the fastest ship around, but makes up for it by being nigh unstoppable. Not sleek or sexy by any means, but sturdy and utilitarian with massively powerful engines for its size.

[@PurpleRhymesWithOrange]

Even the Star Trek TOS technical manual included a tug. I kitbashed one myself based on that book.

[@DarkVoidIII]

One of my favorite tugs was from a TV series the ABC here in Australia ran on it's free to air channel. It was called "Escape from Jupiter" and there may have been a series called "Return to Jupiter" as well. They featured a space tug that was not much more than rocket propulsion systems and a swivel mounted maneuvering system for adjusting travel in other directions. I'm not sure if it was on both series, but it was quite literally a basic space tug. I quite liked the design, very simple and elegant to animate. It might not have looked like much but it got the job done.😁👍👍

[@DarkVoidIII]

This was from before they figured out that Jupiter was a gas giant. I think back then everyone thought Jupiter was a massive planet with lots of atmosphere.

[@AtomicHombek]

AHTS former crewperson. Can confirm how awesome they are. Moved rigs and cargo, it does everything and they are tough as nails. Squish most other ships because of the ice rated armoured hulls. If you get a chance to tour one, do so. Especially the bridge with the forward and rear control stations. Right out of science fiction, MFD touch screens and joysticks. LIDAR, GMDSS, two types of RADAR, GPS, and GMDSS radios. Very high tech, arguably the highest, industry. Trust me on checking out the bridge, throw some green paper over the windows and it could be straight out of Firefly.
