Hello Phil,

Adding 40 tons of fuel in drop tanks bumps the hull up to 140 tons which technically is a custom hull using the next larger hull size which is 200 tons. The Type-A drive for a 200 ton hull gives a performance of J1, M1, and P1. If the tanks are retained I think that the performance would be two one parsec jumps which empties the tanks and would allow a third jump of two parsecs.

Yes, a Model/1bis computer would allow a 2 parsec jump. A Model/1bis computer can run 4 points of programs and has no storage capacity. In order foe a Model/1bis computer to make a 2 parsec jump the generate program would be loaded to generate the flight path (1) feeding the data into the navigation program which in turns interfaces with the Jump 2 program. The generate program would be unloaded and the maneuver program would be installed to make the run to the 100-D limit. To calculate a 1 parsec jump the following four programs could be installed and running in the CPU: Maneuver (1); Generate (1); Navigation (1); and Jump 1 (1).

I thought I had typed Model/2bis which would allow 6 points of programing to be loaded at one time without storage capacity. The programs I would load into the CPU at one time would be Maneuver (1); Generate (1); Navigation (1), Jump 1 (1); and Jump 2 (2). The Maneuver program allows the ship to use the maneuver drive while heading to the 100-D limit while the generate program is creating the flight plan which is in being fed into the navigation program which interfaces with the J1 or J2 program.

At TL 9 I would probably use the Model/2bis computer since it can handle 6 points of programs but a Model/3 computer would be an alternative since it has storage capacity. At TL 10 I would upgrade to a Model/4 computer since it has more CPU and storage capacities.

Right!

24Dt's for the first jump plus 12 for the second & there's still 4 left over.

In my example I was thinking of an ex-scout 'borrowing' the use of the j-tanks from a local Scout Base with the caveat that he would leave them behind for recovery.

It also occurs to me that keeping the tanks would allow the Scout to to effectively possess J3 capability.

Could come handy on certain survey missions.

Would it be possible for a Scout to carry & retain enough external tankage to allow J2+2?

With 20dT's internal & 40 external, a Scout could use 28dT's for each J2 with four left over, I believe.

p.s. wouldn't a Model/1bis also work just fine for either of our examples?

Evening from the Pacific Northwest Phil,

With the tanks retained the scout courier could make an initial jump of 2 followed by a second J1 jump using a Mode/2 computer.

That would provide an initial J2 (dropping tanks) & then another J2 w/o having to refuel thus making a total of 4 parsecs possible even if a 'void jump' occurs.

As far as the cargo goes, I think it would be quite possible & probably even routine to use any 'extra' staterooms to store cargo thus giving a possible total of 6dT's if travelling solo or five if travelling with a partner.
