Hey Skaran,

Here are my comments:

Personally I think that anything which has a volume should have mass if it doesn't it has a density of 0 and is therefore a perfect vacuum.

I agree in the real world the adding of the adapters should add a small amount of mass and volume in addition to cost. However, the amount may be relatively small when compared to the overall payload pallet as not to be really needed for the game universe.

The torpedo description seems closer to sea going types rather than the general purpose (TL20+) ones carried by spacecraft.

A sea going torpedo is propelled through liquid and a space going torpedo is propelled through vacuum. To me they are pretty much the same.

Incidentally in real life torpedoes could be carried externally on grapples by aircraft. Missiles in TNE/FF&S can also be carried this way. Perhaps I'll just port grapple rules in from this system.

A bomb rack is basically a grapple type system, which is what I think the SM payload pallet simulates.

Thanks snrdg051306.
On another matter if I'm putting a point defence system on a ship like a destroyer escort it says to multiply all numbers by 10 and designed as a 6 attack, so if I'm interpreting this correctly a rating 5 system would have a mass of 45x10=450 tons occupying 450 kiloliters and would cost 150 million. Power required would then be 450x6=2700. Power seems a high to me even a rating 2 system would require power of 300*6=1800 if I have this right. Of course this system can fire as needed but I cannot see small escorts being able to generate the power for this and all their other systems.

  Torpedo Note: IIRC either in SM:P or Traveler it states that after a specific tech level when torpedoes can be fired in any medium all such weapons are referred to as torpedoes. So after a specific TL even missiles are referred to as as torpedoes.
  I will check my files on my game PC and see if I can find the info about torpedo launchers and other things.

Sorry to say Skaran, that I haven't gotten to the SM: P Point Defense System yet, but I check the rules out and get back to you.

[snrdg051306]

MarkC being a long time Traveller, Original to Mongoose versions I haven't checked out Traveller 5 yet,  gear head I don't recall, but I could be in error, torpedoes being any different than missiles except maybe damage. Besides a torpedo is really a missile designed to be launched in a liquid. IIRC weren't early missiles called air torpedoes. I'll have to check some sources.

Ok torpedo tubes are listed in the collected rules on SM under the SM:P VM errata and are on both the ISC and J carriers on Data Net #1.

Skaran, my calculations with the exception of power matched yours

Why did you use 450 as the rating for the Escort sized PDS?

The total Point Def. Power Cost, SM: P VM p. 114, formula is written as (Rating) x (Attacks) which I take to mean the rating, available from 2 to 8, times the number of attacks, which can be from 1 to 6. Per the formula a non-escort PDS system would have a power cost of (5) x (6) = 30. Using the PDS on an escort the formula is (5) x (6) x (10) = (30) x (10) = 300

Unfortunately, I don't appear to have any material that has a escort size vessel to verify my understanding.

Thanks snrdg051306.

Thanks MarkC for finding both. I am really going get my eyes checked seeing as how I looked at the errata on the armor belt and total missed the torpedo tube reference.

[markc]

The carriers also have escort sized PD.

For my calculations on PD it looks like I multiplied using the revised mass of the system why I did this is unclear at the moment.

I have now redone the Moth class away boats in another thread to incorporate the hardpoints required for the pallets. I will repost these shortly back in the SM section.
