Why is that? It won't work as a marine vessel to board enemy vessels?
Let me preface my answer by referring you to the
How Crunchy do you like your Traveller thread and poll. I describe
MTU as "Rocky Road; it's hard and soft, crunchy and gooey, all depending on what aspect we're discussing. When it comes to zero-gee, vector movement, and the like
MTU is as crunchy as all hell.
You are
not docking with a vessel which can still maneuver, you are
not docking with a vessel which can still yaw, pitch, or roll, and you are most certainly
not ramming the nose of your only ride home into the crystal-iron hull of another vessel just to try and make a hole through which your marines can board.
If a vessel is incapable of movement, you can "dock" after a fashion and send out parties with breaching charges to make all the holes you need. You aren't, however, going to be piloting a flying jackhammer, auger, drill press, cutting torch, chisel, or other "tool" big enough to cut, punch, grind, or burn it's way through another vessel's hull because you're aren't going to be suicidal enough to risk damaging your only source of life support and your only ride home.
Yes, I know some referees think forcibly docking with a vessel able to maneuver is somehow possible. One idiot even suggested it's the same as a moving plane landing on a moving carrier, apparently and perhaps deliberately overlooking the fact that the carrier
wants the plane to land safely. Forcibly docking with a vessel able to maneuver is not possible, however.
It may be fun somehow for the referees and players involved, it may be the most operatic form of space opera, but it's not possible and no one can seriously claim otherwise.
Keep in mind that I am not showing the civilian variant that removes the acceleration benches and has lots of cargo space.
They may be perfectly logical and workable designs which will be well received. This flying jack hammer, however, taints the entire product IMHO. You might as well publish a shuttle design which reaches orbit thanks to the efforts of eight tiny reindeer.
I'm sure some other people will like it, but the science part of
Traveller's science-fiction dies a little more with this design.
