Topic: 4513 Tech Law: Vehicle Manual Errata

[Marc R]

(All errata thanks to Defendi)
   
Torpedo tubes were left out of Vehicle Manual. A torpedo tube takes the same volume and mass as a pallet. Add to this the mass of all the torpedoes in the magazine. The volume of the torpedoes is the same as their mass. It is assumed that any torpedo can be loaded into any tube the same size or larger than the torpedo.

[Marc R]

Fighter Racks were also left out of Vehicle Manual. A fighter rack has a mass of 1.1 times that of the fighter it carries (essentially, .1 times the mass, plus the fighter itself.) It has a volume equal to the fighter mass, which essentially accounts for the flight deck, the area inside the ship adjacent to the racks, where the flight crew operates.

A fighter rack has the cost of mass of fighter*20/3 and a crew of mass of fighter/200.  Fighter racks are not one size fits all.

Cramped: This ability cannot reduce a critical below an A in severity.

[Marc R]

[pg 42] The Terrain Effects Chart. The headings under the chart description are listed as

Wheel / Terrain, Walker / Track, Hopper, Surface / Jumper, Effect and Gravitic.

They should read

Wheeled / Tracked, Walker / Hopper, Jumper, Surface Effect and Gravitic.

[Marc R]

If you have multiple weapons in a mount, you multiply the damage done by that number, but not the critical. For instance, is you have six blasters, and you roll of 26B, you actually cause 156B damage.

[Marc R]

[pg 99], Armor Belt Mass should be divided by 100 in the equation.

[Marc R]

I never say how to repair hits on ships.  Use the following rules:  The cost multiplier of the armor belt in credits per hit, times the multiplier for the CAT, per hit.  If it has no armor belt, use 100 credits per hit multiplied by the cost multiplier of the CAT. If it has a superior quality bonus, multiply the cost by its multiplier of the CAT and the quality multiplier.

[Marc R]

The attack charts were poorly modeled in the Vehicle Manual. New ones are available for download at the Iron Crown website (www.ironcrown.com). Do NOT use the errata directly above without these attack tables, the ones in the book do too much damage at the lower levels.

[Marc R]

Security levels on ships:  Unless otherwise noted, assume 3 on normal ships and 5 on military ones.

[Marc R]

Missiles do not close range by a mark number.  Handle them the same as torpedoes.

[Marc R]

There is no fuel cost for a fission reactor.  As a rule of thumb, figure 100 for nine months usage, per point of energy.

[Marc R]

For cost, a Torpedo Launcher is the same as a pallet with multiple shots.
   
A launcher can multiple magazine of different types of ammo, and can fire a different type every round.
   
A torpedo launcher takes the same power as a pallet.

[Marc R]

You don't round up when determining strong points.

[Marc R]

When using EW to counter another ship's EW, you only drop the other ship by the sam value as the EW you used.  For example, if a ship has +50 in defensive EW and you successfully counter with +10, you drop theirs to +40.

[Marc R]

Torpedoes add +50 to their attack rolls in addition to their mark numbers.

[Marc R]

Weapons are fixed unless otherwise stated.

Recap of Possible Errata submission with recommendations that, I hope, makes more sense over my original comment;-):

There seems be an disconnect between the Select Hard & Strong Points (4) and Select Payload Pallet (10) vehicle construction rules.

Select Hard & Strong Points (4) states that:

1 - Hard points are necessary to mount a missile launcher, auto/projectile cannon, or payload pallet.

2. All vehicles have a minimum number of valid strong points, just as a side effect of solid construction. This number is equal to the mass of the vehicle (in metric tons) divided by 100. All vehicles have at least 2  strong points.

3. Example 1: Gary is satisfied with the two free strong points. He doesn't buy any others.

In the example on p. 109 after Determine Targeting Bonus (9) Gary appears to mount both Blaster Cannons on one of the two inherent strong points.

From the example associated with Select Payload Pallet (10) p. 110

Example: Gary’s TMAC will not be used for delivering payloads, nevertheless, it should have something. Gary selects a single compact torpedo, which at his tech level is Mark 10. The pallet masses 1 metric ton and has 1 kiloliter of volume. The torpedo weighs a mere .25 metric tons. It takes 1 power to target and fire, and ¢26,000 (¢1,000 for the pallet, ¢25,000 for the torpedo).

From the example on the payload pallet Gary appears to have incorrectly mounted the compact torpedo/payload pallet on a strong point per

Hard points are necessary to mount a missile launcher, auto/projectile cannon, or payload pallet.

Adding a hard point at either Select Hard & Strong Points (4) or Select Payload Pallet (10) is required. This adds 2 tons, 2 kiloliters, and a cost of ¢800 to the design as part of the new construction.

If the payload pallet is a modification after the hull frame has been completed the cost is going to be, I think, ¢6,800 (CAT Cost Mult for XVI x Hard Point XVI Cost), per

Adding after the fact requires more work, and the cost is multiplied by the cost multiplier of the material (the base, not the total).

Recommendation 1:
Insert text to the Payload Pallet example concerning the need to add a hard point.

Example: To accommodate the payload pallet Gary must add a hard point to the TMAC. Referring to the Strong and Hard Points chart on page 98 installing a hard point to a CAT XVI hull frame requires 2 tons, 2 kiloliters, and a cost of ¢800.

Recommendation 2:
Insert text to the Hard & Strong point example to include the possibility of carrying non-energy weapons.

Example: Gary wants a little more flexibility in the TMAC's weapons mix and buys a hard point. Referring to the Strong and Hard Points chart below he installs a hard point to the CAT XVI hull frame which requires 2 tons of mass, 2 kiloliters of volume, and a cost of ¢800.

By adding the hard point the intermediate and final calculations will be adjusted by the appropriate amounts.

Step 20 Select Maneuverability cost formula is

Total Cost of Maneuverability: (# of Drive Units) x 20K

In the example on p. 115 the cost is

¢100,000 ( 10,000 x 10),

Is the base cost 20K per the formula p. 114 or 10k per the example on p. 115?

I would go with the non-example version.

Thank Defendi,

Total Cost of Maneuverability is equal to (# of Units) x 20k per the equation on SM: P VM p. 114.

The use of 20k adds another ¢100,000 to the price.

Errata to the Fusion Drive Fuel rule on p. 115 from:.

Fusion Drive Fuel
Most of details of liquid deuterium are outlined under the fusion drive. For refueling purposes, use this equation:
Cost of Liquid Deuterium per Metric ton: ¢50,000

to:

Fusion Drive and Reactor Fuel
Most of details of liquid deuterium are outlined under the fusion drive p. 103 and/or reactor p. 116. For refueling purposes, use this equation:

Cost of Liquid Deuterium per Metric ton: ¢50,000
