Did you ever create anything to park in the hangar?

Superb ship. Using mine as a long-range space prospector, to which end I've actually built a matching ion miner that fits neatly into the hanger instead of a rover.
If you are careful, the tanks last a very long time and are easy enough to refill once you put the drill on a piston, which I'd highly recommend. I had none of the air-leak issues other people have mentioned, was tight from the get-go.

Very happy with this ship. Was simple to build, easily modified to suit specific needs, has excellent lift capabilities (with every container filled + a miner docked inside and another one on a roof mounted connector I added, it still lifted easily enough at 1.00 gravity). Would absolutely recommend this ship to those who are looking for something that can do a bit of everything (I'd stay well away from combat with that many hydro tanks on display though).

Funny, I have an airtight hangar (even though I can see under the door through the wide crack), but the bridge area is not sealing. Haven't figure it out yet, maybe I too missed a block somewhere.

Same experience as @PaladinDrake. I stumbled onto the search keyword exploration, which led me here. Finally, a jump drive ship that isn't huge. Looks good too!
PaladinDrake 15 Feb, 2023 @ 1:48pm 
I was searching the workshop for hours for a ship like this. I wanted a pretty small large-grid ship with space for quarters and a hangar, something like the MSR from Star Citizen, and this fits the bill exactly. Thank you for posting it. It's going to be my main ship going forward.

This is my favorite ship honestly. I was able to retrofit the upstairs with a bed, shower, toilet. Added 4 solar panels that still makes it look good. I think I did a few more things but I can't remember. Lol.

I absolutely love this ship, it is continually my go-to for exploration. Aside from that, what is the station in the screenshots?
[Alt-tron] 13 Aug, 2021 @ 6:13am 
The Reclaimer has come a long way from it's humble exploration ship beginnings. I must thank you for designing such a nice hull shape. Although it's glaring weaknesses, it has evolved into one of the most formidable stealth combat ships to ever maraud on the official servers.

Just found one buried in ice, with the bodies of two engineers. I look forward to refurbishing it, and making it fly again.

Perfect Ship, I really like it so much. thx @Major Jon
Major Jon  [author] 2 Apr, 2021 @ 3:02pm 
It's meant to be airtight. I would look around the cryo pods, if there's a leak, it's probably there. Btw the build info mod can find air leaks for you.
ZazaOni 2 Apr, 2021 @ 10:18am 
Hey man we need help with something, we have a airtight bridge but the hanger is not airtight?
Is it not meant to be or did we just miss a block?
Major Jon  [author] 14 Mar, 2021 @ 6:40pm 
There's two passages there, they are supposed to be beds. They were pretty common before the dlc beds and I wanted to keep it dlc free. You can switch them out for the new ones ofc if you like.
Ben2069 14 Mar, 2021 @ 6:36pm 
Best design i've seen. One question though: what is the room above the bridge for? You have a nice set of stairs leading up to it, but the room is empty (or did i miss something?).
Major Jon  [author] 2 Mar, 2021 @ 8:49am 
Uh I don't know, it has 2.5 g's, should be plenty for every planet. Even with all the cargo containers filled to the brim with ores it should be easily enough. Did you perhaps forget to fill the tanks and only put some ice inside? cause the 4 o2/h2's can't produce hydrogen fast enough for all the thrusters.
Top_Flight 2 Mar, 2021 @ 7:44am 
Having trouble getting the ship to even get off the ground. I have fully built it and double checked everything and all the engines are working. Any ideas?
Major Jon  [author] 26 Jan, 2021 @ 5:00pm 
Maybe you just don't have enough ice? You need 3000 tons to complete fill it. Even with its drill it takes a long time. I would recommend setting up an ice quarry with a tank farm and filling it from there. If you do have enough ice, make sure it's powered (via batteries or hydro engine), and look at the small tanks. They are set to stockpile in order to serve as an emergency reserve.
honestonion 26 Jan, 2021 @ 4:03pm 
I cant get this ship to go anywhere. Im unsure what im doing wrong.
It is all built and ive put ice into the storage compartments and its been pulled to the o2/h2 generators but my hydrogen tanks arent refilling. ive turned off all thrusters and set all tanks to auto refill but nothing is happening?
What am i doing wrong D:
Panda 24 Jan, 2021 @ 7:42pm 
I lifted this ship off of Earth planet full of ice. It has no problem getting to space.
Major Jon  [author] 12 Jan, 2021 @ 1:25pm 
I'm like 99% sure that's enough, 4 big tanks is a lot for such a small and light ship. If you use the thrust override to save some fuel, you can probably make it with 3% or so hydrogen used. You should charge the batteries though, so you wont need any hydrogen for power generation.
X99 12 Jan, 2021 @ 12:55pm 
How much hydrogen does this ship need to get to space from a 1g planet? I built a slightly modified version of it on one of the official servers, and since I'm nowhere near an ice lake, fueling it is taking forever (after a week straight of mining ice veins nearby, with all thrusters and engines off since it's still connected to my base's turbines, it's only at 11 percent capacity)
Sturmtiger 28 Dec, 2020 @ 9:37pm 
So i tested the Ship. After some Days to fuel it up with the on board O2/H2 Generators XD. I have to agree, it didnt have the Thruster-Power to lift from earthlike planet with full cargo containers. Thats what you have to keep in mind. If you try to land after mining some asteroid dont be to greedy with ores or you will leave a good mark onto the surface. But this ship is all you need to have a bit of everything. Maybe a little warning in the discription, to not overload this ship would be nice.
Sturmtiger 25 Dec, 2020 @ 1:15pm 
Thx again to: Major Jon found it at first try! I was blind maybe that i missed it. It sits right behind the hydro thruster between the hydro engine and the hydro tank. Portside ( left side for me with no naval background^^ ). I will give this ship a Test in the next few days. And will leave you my thoughs about it. Thx again for your help. And like the rest i love the design. Good job. o/
Major Jon  [author] 24 Dec, 2020 @ 8:29pm 
The grav gen is on the portside behind the hydro engine and wedged between the stairs. You should be able to reach that spot without grinding anything down. Or just cut down one of the stairs :)
Sturmtiger 24 Dec, 2020 @ 8:15pm 
Short question i building this ship at the moment and im in the last phase. the Projektor tells me there should be a grav generator in that Ship? I build it by hand. Block after block. Did i miss the grav gen or it wasnt implemented yet? If i missed it pls... tell me where it belongs to, then i didnt find the place in the projektion. friendly greetings and merry X-mas to you all!!!
DNBANB 20 Dec, 2020 @ 2:47pm 
1200 hours in and I've finally found an exploration ship I can build early enough for system exploration to be worth while. One of the top ships in the workshop and by far the best exploration ship. Clean, easy to understand design with no wasted space. I slapped a connector on the nose of one of this author's speeder bikes which fits perfectly in the hanger and had a complete planetary exploration package. I use this set up as my advanced scouting platform to scope out rare ore and ideal building sites. I haven't had any issues with fuel, but the drill is perfect for scraping out enough ice from the surface if your stock gets low. Excellent work sir.
Major Jon  [author] 17 Dec, 2020 @ 1:31pm 
It has enough thrust to lift 2.5 times its weight and enough fuel to hover for about 4 hours on earth (1x inv). Did you put something in the hangar and didn't connect it to the connector? Cause that will make it slowly fall to the ground and tip over. Gyros and thrusters in this game only compensate for the grid they're on and subgrids, not for any additional weight.
Nomad 17 Dec, 2020 @ 1:12pm 
This ship doesn't seem to have enough power to hover on an Earth-like planet. If you let it hover for an hour or so it lists and eventually falls to the ground.
[4DVIP] MrM 15 Dec, 2020 @ 9:22pm 
this is seriously a great ship. We currently have one turned jump ship with reactors and 3 jump drives and one as is one a new play as our first ship to leave the planet. Its so rare to find such a good ship that can be used in early game and would love to see more hydro powered designs!
Major Jon  [author] 14 Dec, 2020 @ 10:31am 
Grinders only grind blocks on different grids. I just had some space left and didn't really know what to put there tbh. They're kinda like trex arms, I know :)
I think they are still nice to have though, you can push stuff into them with a tugboat, or just fly next to the welder with a damaged ship. Large grid welders and grinders have a fairly large radius after all, much less annoying to repair stuff with them than with you hand welder.

Also yes, the one from the piston gun is I think the fifth iteration of this in the last screenshot.
Septimus 14 Dec, 2020 @ 9:52am 
btw, isn't it like a final iteration of the ship featured on your Piston Jolt gun ? love the aesthetic and shape overall
Septimus 14 Dec, 2020 @ 9:48am 
I don't get the welder/grinder placement. The welder at least can be used to repair the missile launcher and the drill, but the grinder seems to be too far on the back to be properly used and, most importantly, doesn't it hurt his surrounding while being used ? no offense, genuine question
hobart 12 Dec, 2020 @ 11:10am 
fixed it! it turns out that it was merely an unfinished conveyor junction above the medical station
whoops!
Major Jon  [author] 12 Dec, 2020 @ 10:29am 
It's definitely airtight on my end, you must have missed to weld up a block. I would suggest removing the prog blocks (they are not needed). The issue is probably around there. The airvent is also there, so you can find the leak with the buildinfo mod.
hobart 12 Dec, 2020 @ 10:07am 
why is the front of the ship not airtight? is this a problem on my end, or yours?
Major Jon  [author] 9 Dec, 2020 @ 1:46pm 
I checked and there was indeed a small problem with the conveyoring. I switched some small hydro tanks out for hydro engines mid building and forgot to change the conveyoring, fixed it now. It only affected the welder and grinder though, the thrusters were already fine, I guess you missed to weld up a block somewhere.
Nicole Morningstar 9 Dec, 2020 @ 1:21pm 
looks a lot like the Mercury Starrunner I love it :3
tuks 9 Dec, 2020 @ 12:21pm 
built this in survival the other day and noticed the front hydrogen engines didn't seem to be connected (and with that the grinder/welder too I think)? I replaced them with 4 reactors anyway and moved the grav gen and vent 1 further out for this... same should work if you just replace the grav/vent and curved conveyor tubes though to stick with your design!
sweet ship though, thanks! :)
Snakewitch 7 Dec, 2020 @ 9:56am 
Fair enough, my nomad ship design took me easily around 6 hours and it still has a weird yaw when under speed that I still haven't figured out.
Thanks for responding, it is always nice to discuss these things with more experienced workshop creators. :)
Major Jon  [author] 7 Dec, 2020 @ 9:52am 
It's definitely a lot harder to detail large grid ships, especially the interiors, but certainly possible (subgrids). I think the shape is far more important than the detailing though. And the best way to get a good shape is to try out a lot of different things and iterate on your design. Since a large grid block is the equivalent of 125 small grid blocks, it just takes me way to long to change the shape on large small grid ships. I would only try that if I already had a shape in mind that I know will work.
Snakewitch 7 Dec, 2020 @ 9:33am 
I am in love with your ship design and am a big fan, I have a question for you.
What is your opinion on large, small grid ships?
I find them to be time consuming to design, but I think their larger opportunity for detail makes up for it. (Transparent LCDs for actual HUDs, vents that aren't the size of a small house, single buttons)
Procedural Texture 7 Dec, 2020 @ 9:14am 
Despite more than 2000 hours in this game, I was always unhappy with my builds until I started pulling apart your ships and learning your tricks. Now I'm merely dissatisfied. Thanks for the lessons!
This looks like a fitting tribute to the Mercury Star Runner, but with a Major Jon flavor.

Hehe something nice to fit with luma
(also make new planets, you make one of the best)
Isley of the North 6 Dec, 2020 @ 7:46pm 
Woow Looks amazing! How did you learn to build like this? You're insane
Locomotor79 6 Dec, 2020 @ 8:58am 
hmmm nice compact it has everything
and you main drill is good for ice and gravel since you got only basic reff's on the ship
