Hello all,
Here is material from HG 1e Softcover and PDF Capital Ship Design Rules and the Capital Ship Design Example pp. 69-72 and Traveller HG 1e Errata that I believe that is incorrect based on the rules as I understand them. Hopefully I am not as has been mentioned creating "fan fiction". Note: The softcover HG 1e in my collection is the printing with the Mercenary Table of Contents, which is the material below references HG 1e PDF.

In Step 2, the Power Plant tons equation in the text should be (0.05 x 0.75 x 75,000) 2,812. 5 tons versus (0.05 x 0.75 x 7,500) 2,812.5 tons
Proof:
(0.05 x 0.75 x 7,500) = (0.0375 x 7,500) 281.25 tons
(0.05 x 0.75 x 75,000) = (0.0375 x 75,000) 2,812.5 tons
2. HG 1e PDF Page 70
In Step 2, the TL 15 Power Plant cost in the text and Summary So Far table should be MCr14,062.5 versus MCr7,031.25
Proof:
HG 1e PDF p. 63 Power Plant Cost per ton is as follows:
Chemical power plants MCr 1.25
Fission power plants MCr 1
TL8–10 Fusion MCr 2
TL11–14 Fusion MCr 2.5
TL15 Fusion MCr 5
Antimatter plants MCr 2.5
(2,812.5 x MCr5) MCr14,062.5
3. HG 1e PDF Page 70
In Step 2, the Summary So Far Table Running Total cost should be MCr42,211.25 versus MCr35,180 due to the corrected cost of the TL 15 Power Plant price.
Proof: 19,250 + 7,500 + 1,218.75 + 14,062.5 + 180 = 26,750 + 1,218.75 + 14,062.5 + 180 = 27,968.75 + 14,062.5 + 180 = 42,031.25 + 180 = MCr42,211.25
4. HG 1e PDF Page 70
In Step 3, the equation for the fuel processor tons in the text should be (33,750 / 20 / 2) 843.75 versus (37,500 / 20 / 2) 843.75 and the cost of MCr42.1875 is correct.
Proof:
Jump Fuel (0.4 x 75,000) 30,000 tons
Power Plant Fuel (2,812.5 x 2/3 x 2) = (1,875 x 2) = 3,750 tons
Jump Fuel 30,000 tons + Power Plant Fuel 3,750 tons = 33,750 tons
Fuel Processor tons = (33,750 / 20 / 2) = (1,687.5 / 2) = 843.75 tons.
Fuel Processor price = (843.75 x MCr0.05 per ton of fuel processor) = MCr42.1875
5. Delete the Traveller HG 1e Errata change for calculating the fuel processor tonnage and cost which is using the incorrect total fuel tonnage of 37,500 tons versus 33,750 tons.
6. HG 1e PDF Page 70
In Step 3, the Summary So Far Table Running Total for tonnage is correct and the cost should be MCr42,254.4375 versus MCr35,223.1875 due to the corrected cost of the TL 15 Power Plant price in Step 2.
Proof:
From Step 2: MCr42,211.25 + Fuel Scoops MCr1.000 + Fuel Processor MCr42.1875 = 42,212.25 + 42.1875 = MCr42,254.4375
7. HG 1e PDF Page 70
In Step 4 the text for the bridge cost modifier should be MCr0.1 versus MCr1 and the Traveller HG 1e Errata entry of "the bridge should cost MCr150 (the table is correct)" should be used.
Proof:
HG 1e PDF p. 63 Capital Ship Section Table: A 75,000 ton hull has a Hull Code of CK the number of section for a hull code of CK is 4.
HG 1e PDF p. 65 Command Module/Bridge Tonnage: Number of sections x 0.5 x Ship's total tonnage
HG 1e PDF p. 65 Command Module/Bridge Cost: Command module/bridge tonnage x MCr.1
The HG PDF 1e PDF Capital Ship Design Command Module/Bridge text p. 63 MCr multiplier could either be MCr1 as shown or MCr0.1. By using the Traveller HG 1e Errata entry that the bridge cost is MCr150 the command module/bridge MCr multiplier can be determined by manipulating the cost equation with the bridge tonnage and the cost of MCr150 per the Traveller HG 1e Errata entry.
Command Module/Bridge 1,500 tons x MCr? = MCr150 = MCr? = MCr150 / 1,500 tons = MCr0.1.
8. HG 1e PDF Page 70
In Step 4, the command bridge cost should be MCr48 versus MCr2,250 in the text and in the Summary So Far Table
Proof:
HG 1e PDF p. 44: A command bridge costs 50% more than a conventional bridge of the same size. Capital ship command bridges take up 80 tons per section of ship and located in a single location (which may be separate from the main bridge).
HG 1e PDF p. 63 Capital Ship Section Table: A 75,000 ton hull has a Hull Code of CK the number of section for a hull code of CK is 4.
Command Bridge tonnage = 80 tons x 4 sections = 320 tons.
Command Bridge Cost: Per the rules the cost of a command bridge is 50% more than the cost of a conventional (command module/) bridge of the same size. A 320 ton conventional (command module/) bridge cost is 320 tons x MCr0.1 = MCr32.
The command bridge cost is 50% more than a 320 ton conventional (command module/) bridge of MCr32 which would be MCr32 + (MCr32 x 0.5) = MCr32 + MCr16 = Command Bridge Price of MCr48.
9. HG 1e PDF Page 70
In Step 4 the holographic control cost should be MCr49.5 versus 937.5 in the text and in the Summary So Far Table
Proof:
HG 1e PDF p. 46: Holographic Controls: This bridge design incorporates advanced interactive holographic displays, reconfiguring itself to adapt to the current situation. A bridge with holographic controls is always optimised, and gives a +2 bonus when rolling for Initiative. A holographic bridge adds 25% to the cost of the bridge.
Command Module/(Conventional) Bridge Holographic Control Cost 0.25 x 150 = MCr37.5
Command Bridge Holographic Control Cost 0.25 x 48 = MCr12
Total Holographic Control MCr = MCr37.5 + MCr12 = MCr49.5
10. HG 1e PDF Page 70
In Step 4, in the Summary So Far Table Running Total Cost should be MCr42,538.3375 versus MCr39,947.0875.
Proof:
From Step 3 MCr42,254.4375 + Bridge MCr150 + Command Bridge MCr48 + Holographic Controls MCr49.5 + Armored Bulkheads MC36.4 = MCr42,404.4375 + MCr48 + MCr49.5 + MC36.4 = MCr42,452.4375 + MCr49.5 + MC36.4 = MCr42,501.9375 + MCr36.4 = MCr42,538.3375.
11. HG 1e PDF p. 71
In Step 5, change the Summary So Far Total Cost to MCr42,925.3375 versus MCr40,334.0875.
Proof:
From Step 4 MCr42,538.3375 + Computer MCr315 + Software MC72 = MCr42,853.3375 + MC72 = MCr42,925.3375.
12. HG 1e PDF p. 71
In Step 6, change the Summary So Far Total Cost to MCr43,222.375 versus MCr40,631.0875.
Proof:
From Step 5 MCr42,925.3375 + Sensor MC297 = MCr43,222.3375.
13. HG 1e PDF Page 71
In Step 7 the Summary So Far Table Cost of Small Craft should be MCr152 versus MCr112.
Proof:
HG 1e PDF p. 71 Step 7 Other Components:
Full Scale Hangars for 4 cutters and 2 pinnaces (4 x 50 x 1.3 + 2 x 40 x 1.3) totalling 364 tons and costing (364 x 0.2) MCr72.8.
Small craft costs are MCr152 and require a total of 18 crew.
CRB 1e p. 111 Vehicles and Drones Table:
A single 50 ton cutter costs MCr28 and the price of single 40 pinnace is MCr20.
Total small craft cost = (4 cutters x MCr28) + (2 pinnaces x MCr20) = 4 cutters MCr112 + 2 pinnaces MCr40 = MCr152.
14. HG 1e PDF p. 71
In Step 7, change the Summary So Far Total Cost to MCr43,600.6375 versus MCr41,009.3875.
Proof:
From Step 6 MCr43,222.3375 + Luxuries MCr1 + Probe Drones MCr0.5 + Repair Drones MCr150 + Briefing Rooms MCr2 + Cutter Hangars MCr52 + Pinnace Hangars MCr20.6 + Cost of Small Craft MC152 = MCr43,223.375 + MCr0.5 + MCr150 +MCr2 + MCr52 + MCr20.6 + MC152 = MCr43,223.8375 + MCr150 +MCr2 + MCr52 + MCr20.6 + MC152 = MCr43,373.8375 +MCr2 + MCr52 + MCr20.6 + MC152 = MCr43,375.8375 + MCr52 + MCr20.6 + MC152 = MCr43,427.8375 + MCr20.6 + MC152 = MCr43,448.4375 + MC152 = MCr43600.4375.

Change the 2,880 torpedoes = MCr14.4 to 2,880 basic torpedoes = MCr14.4.
Proof:
Traveller HG 1e Errata corrected Torpedo Types Table: Cost per Torpedo
2,880 Basic Torpedoes x MCr0.005 = MCr14.4
2,880 Nuclear Torpedoes x MCr0.015 = MCr43.2
2,880 Bomb-Pumper Laser Torpedoes x MCr0.018 = MCr51.84
2,880 Ortillery Torpedoes x MCr0.012 = MCr34.56
16.Traveller HG 1e Errata
Change the 6,000 missile MCr90 to 6,000 basic missile MCr7.5
Proof:
CRB 1e p. 111 Missiles Table
Cost per 12 missiles (Cr.) the costs below are converted to MCr.
(6,000 basic missiles / 12) x MCr0.015 = 500 x MCr0.015 = MCr7.5
(6,000 smart missiles / 12) x MCr0.03 = 500 x MCr0.03 = MCr15
(6,000 nuclear missiles / 12) x MCr0.045 = 500 x MCr0.045 = MCr22.5
Traveller HG 1e Errata corrected Missiles Types Table: Cost per 12 missiles (Cr) the costs below are converted to MCr.
(6,000 Shockwave missiles / 12) x MCr0.035 = 500 x MCr0.035 = MCr17.5
(6,000 Ortillery missiles / 12) x MCr0.035 = 500 x MCr0.025 = MCr12.5
17. HG 1e PDF p. 72
In Step 8, add the following costs to the text and Summary So Far Table per the Traveller HG 1e Errata;
2,880 Torpedoes = MCr14.4
6,000 Missiles = MCr7.5
12,000 Sandcaster Barrels = MCr6
18. HG 1e PDF pp. 71-72
In Step 8, change the text and Summary So Far table entry of triple particle beam turrets to beam turrets.
Proof:
Traveller HG 1e errata for HG 1e PDF Page 47:
Under Changes to Core Rule Book, add:
Only one particle beam may be fitted to a turret, but this turret must be a triple beam turret.
19. HG 1e PDF pp. 71-72
In Step 8, change the text and Summary So Far table cost entry from MCr2,000 to MCr720.
Proof:
Traveller HG 1e errata for HG 1e PDF Page 47:
Under Changes to Core Rule Book, add:
Only one particle beam may be fitted to a turret, but this turret must be a triple beam turret.
CRB 1e p. 111: Triple turret cost MCr1 x 80 turrets = MCr80
CRB 1e p. 111: Particle Beam MCr 4 x 80 single particle beam weapons = MCr320
HG 1e PDF p. 71 Particle Beam Weapon is TL 11.
HG 1e PDF p. 53 Particle beams are available at TL 8 and the design example has upgraded them to TL 11 which doubles the cost per the Armaments and Screens Table.
80 particle beam turret MCr = Turrets MCr80 + (Particle Beam MCr320 x TL Cost Mod 2) = MCr80 + MCr640 = MCr720
20. HG 1e PDF pp. 71-72
In Step 8, add the following costs to the text and Summary So Far Table per the Traveller HG 1e Errata;
2,880 Torpedoes = MCr14.4

In Step 10, change the Summary So Far Total Cost to MCr56,874.8575 versus MCr55,535.7075.
Proof:
From Step 8 MCr56,473.6575 + Armories MCr22 + Staterooms MCr316 + Escape Pod MC63.2 =
MCr56,495.6575 + Staterooms MCr316 + Escape Pod MC63.2 =
MCr56,811.6575+ Escape Pod MC63.2 = MCr56,874.8575 with ammunition
MCr56,846.96 without ammunition
Standard Design: MCr56,846.96 without ammunition - (.1 x MCr56,846.96) =
MCr56,846.96 without ammunition - MCr56,84.696 = MCr51,162.2618
I am still trying to determine the maintenance cost, unfortunately I am not sure which of the three calculated total costs to use:
MCr56,874.8575 with ammunition
MCr56,846.96 without ammunition
Discount for standard design: MCr51,162.2618 without ammunition
