Apoc's Spacecraft Design Worksheet

Great sheet. I noticed one thing. I choose a third upgrade to a weapon by mistake and couldn't clear that cell.

Try copying a blank (though the same type of cell) into it. Works a treat.
 
Thanks for the updated file. One question that I have regards screens. My copy of High guard seems to suggest that you can have Screens equal to your Power Plant Rating, but your spreadsheet suggests that it is 1/2 your power plant rating, if I am understanding correctly.

Is it possible that I have an out of date copy of High guard, or perhaps am somehow misunderstanding something?

Thanks

Screens are limited to power plant / 2 except for capital ships. Also limited by TL. (High Guard Pages: 50, 64 and 65).
 
Thanks for the clarification. I see the reference on pg 50 (that I hadn't seen before) that says "The number of active screens that a spacecraft can support is limited to the power plant divided by 2, rounded up."

And I also see on page 65 that there is a table relating "the number of screens that may be combined together depending on the Tech Level of the screens", where;

TL - Nuc Dampers - Meson Screen - Black globe
12 - 1 - 1 - 0
13 - 2 - 2 - 0
14 - 4 - 4 - 0
15 - 6 - 6 - 3

However, on pg 64 there is a table above which it states "The power plant rating also determines what weapons and defensive screens of each type in each screen group the ship may carry." This table shows:

P-Plant Rating - # Screens
1 - 1
2 - 2
3 - 3
4 - 4
5 - 5
6 - 6

So I guess the Table on pg 64 is what had me confused. Since I hadn't seen the note on pg 50 I had interpreted the Table on pg 64 to mean that for a Power Plant Rating of 2 you could have a total of two screens.

The example on pg 50 under screens is a bit confusing because it talks about a 20% flicker rate for a single group of two black globes but the accompyaning table appears to indicate that this might actually be 30% (if I am understanding correctly).

Anyway, this example shows that for a ship with a power plant rating of 4, but fitted with 3 nuclear dampers and 2 black globes "Due to the size of the power plant the maximum number of screens in each group is 2" (presumably the power plant rating of 4/2). It then goes on to note that the designer breaks the number of dampers into two groups, where the primary group has two units and the backup group has only one unit. It also notes that the two black globes are grouped into a single group "enabling a flicker rate of 20% to be maintained."

Although I had previously overlooked the info on pg 50 before, when trying to lay out a ship, reading it now it kind of seems that the references on pg 50 and pg 64 kind of seem to contradict each other, unless maybe pg 64 is talking about the total number of each type that a ship may carry, and pg 50 is talking about how many may be active at a given time (or something like that).

Since I'm very new to MGT Rules, I'm not real sure I'm fully understanding this. If anyone can help clarify I'd be very greatful.

Thanks

Page 50 is referring to spacecraft of 100 - 2,000 tons. The chart on page 64 is for capital ships (2,001 - 1,000,000) tons.

As for this part you've got an older High Guard. You should get the High Guard Errata available on the main Traveller page. This corrects it to 30% (also updated in LBB2: High Guard).
 
Thanks. I found the errata and that helps alot.

Looking now at High Guard and the errata, if I am understanding the example correctly, non-Capital ships can have more than PPlant Rating/2 fitted in their hulls, but only PPlant Rating/2 of each type may be active (any others beyind this would be backups).

Also, I see in the errata that for non-captial ships Nuclear Dampers and Meson Screens each take up 20 dtons of space with Nuclear Dampers costing MCr 30 (and a Meson Screen costing 60 Mcr as per the original Core rulebook).

Looking at Apoc's latest spreadsheet though, it appears that the costs of screens for non-capital ships is listed as 50 MCr for either a nuclear damper or meson screen and that the displacement is listed as 50 dton for each.

In addition in cell E250 it appears to suggest that the total number of screens (active or inactive) allowed on the ship is PPLant Rating/2 rather than the number of active screens as described in the text and in the example on page 50, if I am understanding correctly.

Thanks again for all your help. I'm really enjoying messing around with the Mongoose ship design rules but sometimes they can be a little confusing, so I really appreciate any help that anyone can provide in helping me better understand them.

Regards

PF

PS. Once I get a better handle on some of this, I'll try and go back and relook at my design, and maybe make some changes.

No problem, if you have more questions feel free to ask.
