Solid Rocket Boosters for SF?

The space shuttle had them why not SF?<div><br /></div><div>Any ship up to HS 5 can be mounted in a gantry with solid Rocket Boosters attached. And launched into space. One booster per engine that the hull requires. Thing is thatvit does take time to mount a ship in a gantry and mount Boosters (die roll in days but die roll is different for each planet determined by economy type and population code. </div><div><br /></div><div>Benefits: atomic powered craft don't pollute the environment and may proceed directly to jump acceleration. </div><div><br /></div><div>Chem drive ships don't have to refuel and proceed directly on to their mission/journey. Ion power ships can be built and launched from ground but extra cost and time for gantry mounting due to their longer ion drives having to be accommodated.</div><div><br /></div><div>Other benefits: game master needs to enforce a less rail road reason to force the PCs to remain on this planet for the plot hook he has planned, &quot;oh, bummer, it's going to take 10 days for your ship to cue up to a launch gantry. Meanwhile do you wish to try the local canteena?&quot;</div><div><br /></div><div>Some planets may outlaw all atomic drive launches and require chemical boosters</div>
