Note: For the examples of spacecraft design posted on this blog, I mostly use 2ed. Mongoose Traveller rules, but some examples using 1ed. rules will persist until they can be upgraded.

Look at the side column for variant rules I use in my campaign.

10dt Launch, TL8 to TL12; 5.0dt or 4.5dt payload.

10dt Launch

This vessel is the smallest of the interplanetary craft in regular commercial use. Early versions include the use of reaction drives with fusion power plant to heat H2O to plasma state. These lower tech models are cheaper and tend to be used for landers, planetary utility craft, and emergency lifeboats.
Tech level 10 and newer craft will tend to use gravitic drives, and are generally more reliable and capable, though more expensive.





Hull:
     10dt, streamlined cylinder, 4HP, 0.6Mcr.
          {TL8~0.39McrImp.; TL9~0.42McrImp.; TL10~0.45McrImp.;
