Subject: Tugs and Tenders, example of shipdesign based on new and modified rules

A section describing Tugs and tenders could be found in 'New And Modified
Rules' page 8. The rules are simple. Tenders uses 1.5 MASS of hangar space for
every 1 MASS of carried ships whether the carried ship are
FLT-capable
or not. For tugs even simple rules is used: Tugs need a drive that is capable
of 10% of their own MASS plus additional drive MASS equal to 20% of the total
MASS of ships they can tow. Needed a ship of 100 MASS being towed the drive of
the tug should be capable of additional Jump drive capacity of MASS 20. If the
tug itselves have a MASS of 50, the total Jump drive capacity is equal to MASS
25.

Now let say that I need a tender to carring my Manchuria class of a TMF equal
to 94 from a battle inflecting lose of the battleships FLT. I will need hangar
space equal 94*1.5 MASS = 141 MASS. If the tender should
have an average hull and a FLT plus THRUST-4 we would come to something
like this:

TMF(tender)=hangarspace+TMF(tender)*30%(average
hull)+TMF(tender)*10%(FLT)+TMF(tender)*4*5%(THRUST-4)
=>
TMF(tender)=141MASS+0.30*TMF(tender)+0.1*TMF(tender)+0.2*TMF(tender)
=>
TMF(tender)=0.60*TMF(tender)+141MASS
=>
1=0.60+141MASS/TMF(tender)
=>
0.40=141MASS/TMF(tender)
=>
0.40/141MASS=1/TMF(tender)
=>
TMF(tender)=141/0.40MASS
=>
TMF(tender)=352.5MASS

is that so? - let try reversed:

352.5MASS

Average hull 30% => 352.5*30/100=105.75
FLT equal 10% => 352.5*10/100=35.25
THRUST-4 equal 4*5% =>352.5*20/100=70.45

TMF(tender-hangerspace)=105.75+35.25+70.45=211.45+141(hangerspace)=352.4

This is of cause without any defence installations! Now is there any rules
that prevent my tender of carring fighters in peachtime? This tender is also
cable of launching 94 fighters! This is quite a big tender! remember that the
ESU Superdreadnought Komarov class only have a TMF
of 220:-) So shipdesign of tenders carring battlecruisers is quite
unrealistic but this was only for the cause of an example:-)

No. Why should there be? There are no rules forbidding today's fighter
aircraft from being based at civilian airports either - indeed, many
"civilian" Swedish airports do host two or four fighters... and the gigant
tender costs just as much as a gigantic, defenceless carrier (but with one
single, huge bay).

I think you mean peacetime rather than peachtime, though :-)
