You could get very early SY-BB. And that is worth it. ;)

Okay, that might be worth it. I currently have a single rather bumbling SYM FT4 wandering around doing some picket station construction, although the first one was slow enough that I need to reconsider methodology.

Re: Thinking of a new 'Hull Class Availability' House Rule

Here is the penultimate version of my Optional House Rule for Pushing the EL limit on Hull Classes allowed.

Vandervecken’s House Rules V2.32

Optional Rule: EXTENDED HULL CLASS AVAILABILITY – This rule extends the standard Ship/Base Classes available for you based on your EL to be modified so that you can build Ship Classes as listed in AA.CON up to 3 EL early, but you pay the following penalties to do so:

If 1 EL higher than your current actual EL: 2.0 x Hull cost, 1.25 Engine cost, +3% Maint. Cost,and +1 Turn Mode
If 2 EL higher than your current actual EL: 2.5 x Hull cost, 1.5 Engine cost, +5% Maint. Cost, and +1 Turn Mode
If 3 EL higher than your current actual EL: 3.0 x Hull Cost, 1.5 Engine cost, +7% Maint. Cost, and +2 Turn Mode

In addition:
* A Ship/Base hull size is considered to be +(5% x EL difference) in Hull size before doubling the hull size when building a Prototype/First of Class.
* Due to the inefficiencies in the engine design due to the hull's advanced nature, there is a -1 to transit size for Table C4.02.2.
* The ‘First of Class’ fee for any Ship/Base using the Extended Hull Class Availability optional rule that is also a Prototype is 25% instead of 20%.
* Emergency repairs are harder to do on a ship/base build that is even 1 EL higher than the normal maximum class allowed in the AA.CON table and therefore receive a penalty of -1 when rolling for Emergency Repairs. The Emergency Repair -1 penalty cannot be refitted out of any ship or base that had its construction began earlier than the AA.CON table would normally allow.

The difference in EL from your standard maximum Ship Class needs to be noted on that vessel's Ship Control Sheet.

When building a ship/base using this optional rule, use the above table for units that are 1 to 3 EL above your current EL in lieu of M1.03.4.1 - Early Prototypes. If the scan or captured unit is 4+ EL higher than your current actual EL, you will need to get your empire’s EL level raised high enough so that the ship/base design you captured or scanned is only 3 levels (or less) above your EL before you can use the Extended Hull class availability optional rule. So when using Extended Hull Class Availability, no 4 or higher EL Hull Class can be researched/built using M1.03.4.1.

Having a Scan of a unit or a Captured unit will remove the +(5% x EL difference) in Hull size before doubling the hull size when building a Prototype/First of Class. In addition, having a Captured unit of a higher EL will return to 20% instead of the 25% fee for 'First of Class' used normally when extending the normal Hull Class availability of an empire.

On the Ship Control Sheet, the Ship/Base hull class is listed with a +1, +2, or +3 after the abbreviation to denote the difference in EL at the time the ship build is paid for and given to a Shipyard to be started.

On the Ship Control Sheet, Turn Mode modifiers from using this optional rule are notated immediately after the ship’s Turn Mode Number with one Asterisk if the Turn Mode has been adjusted by +1, and 2 asterisks if the TM has been adjusted by a +2 to the TM.

Example, a EL2 empire that builds a Battlecruiser (3 EL above what that empire could normally build) might build a warship that looks like this:
Frieda Class Battlecruiser – A 3 EL early design of an EL2 empire.
BC+3 / 80 HS / 51 HTK
2208.0 / 331.2 MC
[6**] S S S S S S S S A A A A A A A Qa Hs Mgs Ra Qa Mg Ra Qa (ia Ia Ia) <M1> Ra Ra Qa (ia Ia Ia) Ra H Mg <M1> Ra Fa Ra Qa (ia Ia Ia) Fa Ya Ra Qa (ia Ia Ia) [4]
Considered 184 HS equivalent for Prototype/First of Class shipyard usage. If both Prototype and 1st of class, it costs 4363.2 MC to build.

If your empire was at EL3 when you built this BC ship, the example would look like this:
Frieda Class Battlecruiser - 2 EL early design of EL3 empire
1970.0 / 295.5 MC
BC+2 / 80 HS / 51 HTK
[5*] S S S S S S S S A A A A A A A Qa Hs Mgs Ra Qa Mg Ra Qa (ia Ia Ia) <M1> Ra Ra Qa (ia Ia Ia) Ra H Mg <M1> Ra Fa Ra Qa (ia Ia Ia) Fa Ya Ra Qa (ia Ia Ia) [4]
Considered 176 HS equivalent for Prototype/First of Class shipyard usage. If both Prototype and 1st of class, it costs 3792.0 MC to build.

If your empire was at EL4 when you built this BC ship, the example would look like this:
Frieda Class Battlecruiser - 1 EL early design of EL4 empire
1682.0 / 252.3 MC
BC+1 / 80 HS / 51 HTK
[5*] S S S S S S S S A A A A A A A Qa Hs Mgs Ra Qa Mg Ra Qa (ia Ia Ia) <M1> Ra Ra Qa (ia Ia Ia) Ra H Mg <M1> Ra Fa Ra Qa (ia Ia Ia) Fa Ya Ra Qa (ia Ia Ia) [4]
Considered 168 HS equivalent for Prototype/First of Class shipyard usage. If both Prototype and 1st of class, it costs 3160.8 MC to build.

If your empire was at EL5 when you built this BC ship, the example would look like this:
Frieda Class Battlecruiser
1156.0 / 173.4 MC
BC / 80 HS / 51 HTK
[4] S S S S S S S S A A A A A A A Qa Hs Mgs Ra Qa Mg Ra Qa (ia Ia Ia) <M1> Ra Ra Qa (ia Ia Ia) Ra H Mg <M1> Ra Fa Ra Qa (ia Ia Ia) Fa Ya Ra Qa (ia Ia Ia) [4]
Considered 160 HS equivalent for Prototype/First of Class shipyard usage. If both Prototype and 1st of class, it costs 1958.4 MC to build. But if this was a refit design of a vessel you made at an EL that was 1 or more EL before you could normally build this ship, the cost for 1st of Class would be 25% instead of the normal 20%.

Note: Hopefully, your empire will have developed better SL in your weapons and other ship systems as you go up in EL, but I kept the components the same on the 4 examples above to show the increased cost of building higher EL Ships/Bases than you could normally make without using this optional rule.


Refits that include engines whether the original generation or a newer engine generation that are made to a vessel that was built before their class was at the needed EL will always have the engine penalty cost associated with the difference in EL at the time the construction of that vessels Hull was started. It will always cost an extra amount of MC to properly and safely install any engines on that ship due to the EL difference. If you remove the engines from a ship that has an EL penalty, that EL difference penalty does not transfer with the engines. It will use the standard cost and task size to emplace on a non-above EL ship or it will use the penalty cost associated with the EL difference of the new ship and still the standard task size to put on another vessel that was made before the Hull type could normally be made according to AA.CON.

If using the optional AA.CON.04 Generational Hulls rules, note that you cannot EVER refit a ship that uses these Extended Hull Class Availability rules to refit to another generation of Generational Hull. Only ships built at normal EL Hull Class availability can use AA.CON.04.4.

Once you go up a EL, you can re-compute the cost of the Ship design; and all ships built from that turn forward use that re-computed cost based on the new difference in EL. If the EL difference has gone down to zero, the costs will be the standard costs The newer version also may have some of the other penalties reduces or removed. The first vessel of the Hull class that has reduced its EL difference whether by 1, 2, or even 3 EL levels will get a 25% (Instead of 20%) ‘First of Class’ fee. If you make an new design for a Hull class that originally at 3 EL higher but then became 2EL higher, and then do the same at 1EL higher, and finally make a design for that same hull class when it is your actual EL (or lower). In this example you will pay a 25% ‘First of Class fee’ 4 times, the original build and at all 3 of its EL improvement stages. Buying another ship design at the same EL difference of a Hull Class you already have one ‘First of Class’ bought already at the 25% Fee difference has the standard 20% cost the First of Class fee.

It is important to note that any of EL difference penalties that older versions of ships and bases have cannot be refitted to remove their original penalties out. The penalties (including higher maintenance) will be with those ships/bases for the lifetime of their existence. Think of those relics as being ‘Gloriously Archaic’ and they will probably be mothball bait if you aren’t in any pressing wars just years after they are commissioned.

The more ‘Time Decompression’ House rules you may be using that affect EL and SL, the more valuable this optional House Rule will be.
I weary of the chasssse. Wait for me. I will be mercccciful and quick.
