 ===== Unofficial errata =====

+Airlocks: The table on p.42 and the Free equipment box on p.10 have different sizes for airlocks for SM 6-15 ships.
+===Star flower===
+seems to have wrong listed load of 301 as it has 6 cargo for 300 tons, 43.5 cargo in the tertiary battery and 20 people. The correct load should be: 345.5
+Also the price seems to be wrong:
+|number|module|Total price|
+|3	|metal laminate armor		|3|
+|1	|control		|2|
+|2	|stardrive		|20|
+|2	|standard reactionless		|2|

+|1	|enhanced sensor		|2|
+|1	|engine room		|0.3|
+|1	|fusion reactor		|10|
+|6	|cargo		|0|
+|2	|habitat		|2|
+|	|artificial gravity		|1|
+Is only 42.5 million with the listed price of 44.5 million.
+=== Jet fuel price ===
+The $4000/ton price of Jet fuel on spaceships p46 seems way too high.
+Of course such values will depend on how plentiful such is in the setting but it is off by a factor of >10 compared to 2016 refinery prices. The monthly average refinery price of jet fuel/ton has varied from 350 to 450 usd. That corresponds to about 280 to 360 Gurps dollars. As comparison the prices for liquid hydrogen and rocket fuel seem about right for current prices.
+So in a fairly plentiful oil scenario like current earth 1/10 of the price or $400 would seem fairly good approximation.
+As a side note: The $400/ton would make the Molniya-class ramjet from spaceships 8 more reasonable. At $4000/ton the fuel cost would be almost $12000 each and yet the Transhuman space base book says that such transit costs $2000, so the $1200/passenger fuel cost would make it closer to that $2000 in total expected operating costs.

 Not an errata, but if using half systems then installing half size power plant would allow 3000 ton more cargo and installing a much smaller habitat and the remaining in cargo would allow bit more cargo as well totally.
+=== Regulus-class ===
+Is listed as having: \\
+Hot Reactionless Engine (50G acceleration) and Move 50G/c
+But Hot Reactionless engine only has 2G/c acceleration. So the engine is Super Reactionless not Hot Reactionless or the acceleration in only 2g/c

 === Baikonur ===
+Baikonur Third Stage STV is listed as TL 8, but has control room computer and sensors calculated as TL7 and has no other components that are above TL 7, so should likely be TL 7.
 Not really an errata as such more an observation. In the end the first stage is thus controlled by a control room 2 sizes too small for it. Should this not cause a penalty?

+Has listed airspeed of 2450mph, but at 3 modules of 0.5g each it should be 3100mph
 Definitely not an errata, but an observation: This design is also inefficient due to too much armor.

+The descriptive text says: "The barge’s interior is devoted to 255 tons of cargo capacity." But the correct cargo capacity is 85 tons.
 ==== Spaceships 3 ====
+Collision formula on page 32 seems to produce too high values. Collisions according to the formula do about 3.6 times the value they should do.  Just use the Spaceships p.64 formula to fix.
 ===Admiral-class===
 Is missing module 5 in central hull.
-Has 2 Fuel tanks with 15mps listed delta-V each but the table says 1G/15 mps. It should be 1G/39 mps or if the missing module is fuel tank 1G/45 mps.

+Sword-Class Heavy Cruiser in SS3 page 14. The stat-line is listed as having a DR of 100/100/50, but the design has 140/140/70 (which seems to fit the actual stats for streamlined diamonoid)
+Also, it has 10 fixed rear-mounted missile launchers. Does it expect to be running away often? and if so why is the rear armor weakest?
+=== Eclipse-class ===
+The crew listing has "plus all necessary small craft pilots and flight crews." But it does not carry  any small craft as it has no hangar bay or external clamps.
+=== Trinity-class ===
+Has a single Fission Reactor providing one Power Point, but two high energy systems (Major Battery and Secondary Battery), so it should have a note saying it cannot operate both at same time. Alternatively upgrading the fission reactor to a Fusion reactor would solve the problem.
 ===Azrael-class===
 The price is obviously wrong. A quick calculation would indicate 1,901.5 million could be the right ballpark instead of the listed 1,901.5 billion.

+But its ability to operate in high-G worlds is severely limited by the low D-v.
-It can only take off or land on planets with more than the 0.6g if they have atmosphere. Further the d-V is just enough to reach low orbit of 1g planet with a minimal reserve for docking maneuvers,de-orbiting and similar, so it could not operate from larger planets. So no real "high-G" world capability and only limited earth size world support requiring an atmosphere.

+Says that: "Personnel include four control crew, six scientists, and one technician." and yet it has life support only for max 6 people.
+Simple solution is to swap out the three cabins with total life support with something giving more such. Just using 6 cabins allows for that to be carried but maximally one more person. Three cabins and three bunk rooms would allow it to carry the normal crew of 11 and have extra space for maximally 7 others.

+Has 3 factory modules total each requiring a power point, but only 2 power points produced: Solar Panel Array (one Power Point) and Fusion Reactor (de-rated; one Power Point).
