Ship Design Philosophy

In case you were wondering what happened to Core/1 computers, extrapolating it woud mean that you get paid for taking one of the manufacturer's hand, probably a gift certificate worth two million credits.

It probably breaks the assumption about being an inherent part of the bridge, and adds at least a stateroom of heavy iron, resembling an IBM mainframe iconic of the 1970s.

Missiles

1. You have to wonder why no-one's MIRVed the torpedoes yet.

2. Speaking of which, for Multi-warhead missiles, I would have stuffed them full of nukes, though a more calculated approach would have been decoys and defense suppressors.

Well, ummm actually Mongoose Publishing is in posession of rules including MIRVed torpedoes... No idea when it might see the light of day though.
 
I think MIRVed weapons in Traveller are the Multi-warhead missle in High Guard plus I consider Barbettes and Bays an attempt to overload a target's Point Defense much like a ground based Multi-rocket launcher. A true MIRV system would be just packing a bunch of missiles or torpedoes on to a very large delivery system which becomes a single target before releasing a payload.

A MIRV system was originally meant to deliver a multitude of warheads over a very long distance rather than have each warhead carry a huge fuel and engine. For the Russians at the time it was a shotgun effect neutralizing their less effective targeting systems.

How about a delivery system that uses the equivalent of a launch tube and carries a multitude of autonomous fighter drones. It is fired at greater than Distant range, maybe directed to a target or targets by a forward scout, releasing the drones well out of Point Defense range. A spinal Inter Space Ballistic missile. VERY expensive and still a target as much fun as it sounds.

That sounds more like a drone missile/torpedo launcher to me. The drone is the autonomous launch platform that flies to the target and then releases it's payload out of range of the ships point defense weapons.

Most nukes would be stand-off missiles I think. Any naval ship of importance should have at least one nuclear screen, thus rendering contact nukes ineffective so long as it's up. Only after the screen was down would I use contact nukes. Otherwise you are throwing credits out the airlock.

I do hope Mongoose is going to re-working the entire set of missile rules. It needs some serious updating.

Must be one of these, though as I recall, this one tried to drill through the armour first, which in hindsight, seems a mistake.

c. factor 3 - 1334 tons ?
d. factor 4 - 1143.4 tons ?
e. factor 5 - 800.4 tons ?
f. factor 6 - 615.6 tons ?

6. Re-examining the issue of gravitic drives for largecraft, it seems that I've been subjected to a very bad case of editorial lack of oversight, since what I assumed was an example of gravitic drives for an antique hauler, turns out to be a lower tech level fusion rocket. Presumably.
 
1. What do we know about gravitic drives, if we ignore some of the funky results from the whatever algorithms were used on the smallcraft tables:

a. They are twice the tonnage of an equivalent fusion rocket.

b. They cost 2 MCr. per ton.


2. Since gravitics are only available from TL9 onwards, it might be very useful as to when inertial compensators were available, and at what TL various factors were introduced, since that would have a bearing on the actual speed human occupied spacecraft could accelerate at.
 
Minimum sizes for Fusion Power Plants for Spinal Mounts

1'000 tons - 40.02 tons

14'000 tons - 280 tons, presumably

Significant, if they are installed as planetary defences.
 
Missiles

1. I noticed that the mine drone had listed the size of the multi (six)-warhead missile warhead as one hundred kilos, which I felt was wrong, considering the standard missile probably weighs around eighty kilos.

2. the sA reaction drive has a thrust of twenty tons and weighs two hundred and fifty kilos.

3. With a required thrust of eight hundred kilos for a normal missile over six minutes, you can scale the reaction drive downwards by a factor of twenty five, which gives you a ten kilo drive for the missile; sufficient fuel for an hour run is twenty five percent of volume, so that's another twenty kilos.

4. That means, a typical payload of the standard missile is fifty kilos, including sensors and guidance.

5. A multi warhead variant travels at thrust eight, so that's six hundred and forty kilos equals a factor of 31.25, which means the engine is eight kilos, and fuel for an hour is sixteen kilos.

6. That leaves a payload of fifty six kilos, divided by six means that a warhead has a nominal weight of nine kilos, or 9.33 kilos.

7. A long range missile needs a thrust of 1.2 tons, which factors to 16.67 or 15 kilo engine; a forty two minute endurance is twenty one kilos of fuel.

8. That means a long range missile has a payload of forty four kilos, which explains the 0-5 damage.

9. So basically, the drone mine should actually have a 10 x d6 effect if it's really 0.1 tons in weight.
 
Missiles - Power Plant

1. I rather doubt you can make a fusion plant at 4.8 kilos, so it's convenient that a battery will work for an hour at the same size.

2. Actually I forgot about power:

a. normal missile - 4.8 kilo battery; 45.2 kilo payload

b. multi warhead - 3.84 kilo battery; 52.14 kilo payload; 8.69 kilo warhead

c. long range - 5.02 kilo battery; 38.98 kilo payload

If you want to, you can (sort of). I forget the sourcebook, but the suicide drone gives you the mass for a torpedo warhead independently of the torpedo, allowing you to design a multi-warhead carrying drone...
 
The drones are a tad expensive, and at that size, may need to have specially designed mini-vehicles to deliver the payload.


Trivia: if they did manage to build fusion plants at around fives kilos, fuel usage for an hour is a gramme, give or take.
 
Missiles - Torpedoes

1. On the assumption that torpedoes are scaled up versions of missiles, we scale up the sA reaction drive to twenty five tons of thrust, 0.3125 tons, with 0.635 tons of fuel.

2. Power plant sA would be factor 8, and since we only need one eighth of that, 0.15 tons and 0.002976 tons of fuel for an hour.

3. That gets us 1.100476 tons, with 1.399524 tons payload.

4. Assuming the one ton warhead is accurate, sensors and guidance would be 0.399524 tons.

5. Cost would be 625'000 Cr. for the rocket, 375'00 Cr. for the power plant, and a 100'000 Cr. for a bomb pumped laser. That would mean a torpedo costs 1.1 MCr., not counting sensors and guidance.
 
Missiles - Standard cost

1. Reaction drive sA/25 is 20'000 Cr.

2. 4.8 kilo battery is 48'000 Cr.

3. So, not counting sensors, guidance, and warhead, your typical missile costs at least 68'000 Cr.

4. All things considered, missiles and torpedoes are a bargain.
 
Missiles - CT Customized

1. 50 kilos - weight or size?

2. 1 metre long container by 15 centimetre diameter is 0.04125 cubic metres or 0.002946 tons, which seems like a shorter, fatter Stinger missile, of which you should be able to stuff hundred plus into the turret.

3. From what I see, needs to be revised.
