Ship Design Changes - Part Three

Bridge, Computers, Electronics.

More ship design rule changes for my current Traveller setting.

There are few changes to Bridges in this setting. Unlike CT, however, I use the Mongoose Traveller ruling for ships 200-tons and smaller. These ships require only 10-ton bridges. Costs remain unchanged.
   Mongoose rules include a number of available options for bridges, including such items as ejectable bridges, holographic displays, cramped/roomy bridges, etc. I consider most as purely military options. I also decided that ships are constructed to the basic tech available at their Tech Level of construction. In other words, any ship designed at TL 12+ automatically has a holographic-capable bridge, and so forth.

Here is an area of bigger changes. In actuality, these rules are very similar, if not identical, to the Mongoose rules. (I don't have them in front of me as I type this, so I can't verify this either way.)
   I have removed the Fib and Bin options for this setting. A computer will be constructed to the current standards of the tech level. In addition I have increased the CPU ratings for all models, though I have also kept the original Traveller ruling for computer model vs jump number (obviously).
   While I didn't wish to remove that 'hard space opera' feel of old Classic Traveller, I wished to reduce the ridiculous (to modern eyes) computer sizes and low CPU capacities.
   Computer Models 1 though 3 do NOT take up any ship volume, and are 'relatively' cheap. After this, they begin to take up more ship volume, and the costs rise sharply.

It makes no sense for any computer in any science fiction setting to NOT have a backup. After all, people's lives are dependent upon computers when engaged in interstellar travel. To reflect this, computer models 1 to 3 have a single available backup computer, at no extra cost. Models 4 and greater have two backups.
   Ship designers are free to include more backups if desired. Each extra backup requires one ton, and the full cost of the base computer must be paid in full. This provides one additional backup, and the added volume reflects consoles, storage, wiring, etc.

Model#  TL   Volume   Cost (MCr)
   1           5           -             1
   2           7           -             2
   3           8           -             3
   4           9           1            5
   5          10          2            8
   6          11          3           11
   7          12          4           15

A ship is assumed to have basic sensors, of course (inter-system and interstellar travel would be impossible without them). However, I decided that most ship sensor capabilities would be reflected in ship designs (and sensor/combat rules) based off the ship's installed computer model. This reflects processing power available to the sensor operator, which may be a far more important factor than the actual sensor arrays, when one considers the amount of background noise and interference encountered in space.
   The single exception to this is Survey Sensors. These are sensors used to conduct interstellar and planetary surveys, of course. A survey Sensor Suite requires 10 tons, and costs MCr 10.

As with Sensors, these options are based off the ship's installed Computer Model. (I didn't feel like adding a higher number of die rolls to the games I run.)
   Jamming signals and sensors is basically a military action, Civilian ships conduct these actions, but their efforts will be useless when facing a military ship. And you can bet that any military ship will have no problems countering efforts from a civilian vessel.
