150-dTon J2 M2 Pioneer Class Survey Ship

Hi all,

Robert Pearce from Yet Another Traveller Blog has been busy. Together we have been creating new vessels using his geomorph system. The most recent ship is a 150-dTon Pioneer Class Survey Ship. This an old Solomani class now out of service and found in large numbers on the used ship market.

You can find the PDF here: https://travellerrpgblog.blogspot.com/2025/07/pioneer-class-survey-ship.html

Enjoy

One person on Facebook asked "where is the fuel." This was my answer:

The central section of the ship (SC-13 in the geomorphs book) is 68 dTons. Dividing that by a 3m thick deck, you get 22.3 tons per metre of a 3m deck. If the fuel total is 32 tons and you subtract 7 tons for the taper between the main deck and the cargo deck (the triangular blue sections shown in this cross-section), then you still need 25 tons of fuel. I would add 0.4m of fuel (about 9 dTons) in a thin deck above the main deck, 0.4m of fuel between the main deck and the cargo deck (another 9 dTons), some in the wings like a plane (4 dTons), and some behind the fuel scoop (3 dTons).

The fuel is in blue.

That'll be fun to be on the main deck when some laser goes poking through the top of bottom of the ship and start venting LHyd into the main cabin space!

That’s why professionals suit up and go to vacuum in battle. No pesky oxygen.

This isn't an uncommon arrangement for deck plans, of course. The handwave is that the fuel is a combat damage buffer; really, it's an easy way to skip over transitions between square elements like staterooms and angled or curved ones like the hull shape

Yea, I was more thinking "Boy, it sure is getting REAL COLD, REAL FAST right now!"

"Can't move aft, sir, leaking LHyd froze the hatch, heck the entire corridor and the galley, solid."

This is another reason to purge atmosphere -- no air, no humidity, no ice when you slosh a few hundred liters of H2 into the room.
