Why should one use B-17 or B-52 instead of mini bomber in case of using non expensive engines?
My thoughts about that(prices are per bomb):
mini: gateable, one missile per bomber to kill, worst fuel
B-17: 10% or so cheaper(non-gateable version) than mini, one missle per bomber to kill,best fuel
B-52: same price as mini or slightly more, can have shields and jammers, has protection against beamers and missles and can be protected by freighter chaff
Looks to me, that unless enemy beamers threaten my bombers(in which case i'll have problems anyway), mini bombers are best, since their missile resistance is better than that of other bombers, except for B-52 with freighter chaff and they are gateable, so they are more likely to be where i want them.
Did i miss something?

On the other hand, if you want to play the numbers game straight, as you have done with resource cost, it may be worth mentioning that the mineral cost per bomb housing is *significantly* lower in the B-17 and B-52 hulls...
|
For B-17 yes, for B-52 only a bit(min cost of B-52 is around 60-70, mini is , their main mineral advantage is from the less engines needed(B-52 3, B-17 4, mini 8 for same amount of bombs), which gets less important, when either using fuel mizer or prop23 engine.
Which i obviously forgot is mixing bombs and mine field safety.
Mine field safety is also useful with non exploding fields, 50 B-52 can risk a 36LY jump, 400 minis can't.
About mixing bombs, are there any spread sheads to calculate how more efficiently mixed bombing is in case of goal to asap either emtpy the planet or have a small defenseless number of colonists(200000-)?
I'm unable to think up a straightforward calculation, because adding LBU reduces amount of pop killed, but increases amount of facs and mines bombed, so the ability of planet to produce next turn defenses is hampered, which then might yield more pop killed per 2 years than with only normal bombs. What i would guess is that half LBUs half smarts is more inefficient, than just normals.
What if Robber Baron is avaible, then a bombed planet is normally depleted of minerals the same time, which also hinders defense rebuilding. Which means that the ratio LBUs/normals would have to shifted more to nomrals.
Any good rule of thumb?
And if i'm planning to use enough bombers for 1 turn kills, then pure normals is best isn't it?

Can't point you in the direction of a decent bombs spreadsheet utility... I'll leave that to someone else..
But as for views on bomber cost - I Object, your honour!
Mineral Useage per Bomb Housing
Hull / I / B / G
Mini / 9.0 / 2.5 / 4.5
B17 / 6.875 / 1.25 / 1.25
B52 / 5.625 / 0.9275 / 0.625
So successive bomber hulls do use minerals a lot more effectively than their predecessors.
Of course, these aren't the only things to take into consideration. If you want to make a proper formula for the whole thing, then you have to not only take a look at resources (as you have done), but then also the basic armour, weight vs fuel efficiency, basic engines, and the perceived value of the extra slots.
Of course, if you start putting jammers on the spare slots, then that reduces the likelihood of being destroyed by a missile hit, and so makes B17s (for example) more resilient than the Minis...
If anybody really wants to make their head hurt, I suggest thinking about this for a while...
Just out of interest, has anybody else used used the strategy of sticking Super Cargo Pods on B17s/B52s and filling them full of pop in order to execute bomb/pop-drop missions, with any degree of success?

IMO price per bomb doesn't matter so much, as usually you need 100-200 bombs in orbit, but several hundred (or thousands) of weapons to bring bombers there alive.
I'd say minis are more appropriate for close quarters and early attacks, but for long operations in enemy's space you need more fuel and protection. That's what the B-52 hull offers. IIRC B-17 I used in only two games. The first one was slow tech / 15 planets per player, the second one was "primitive" (basically slow tech again ) / no gates. But again, in the later I moved to B-52 after the hull was available.
I can make a list of pros/con's of both hulls. Then you decide what's more important for your way of playing.
Mini bomber
Pros:
- low tech enables early attack,
- gateable, with single bomb even through 100/250 gates,
- easily replaceable (can be built on docks and gated to front).
Con's:
- low armor and fuel,
- no additional protection,
- two designs usually needed,
- can't survive single minehit,
- IS-10 engine cost is a big portion of its price
B-52 bomber
Pros:
- more fuel,
- can mount additional protection (jammers, shields),
- with shields it survives single minehit,
- the cheapest hull per bomb,
- only one design needed,
- IS-10 engine friendly .
Con's:
- not gateable (even B-26 (half loaded B-52) is gateable with damage/losses),
- hard to gather and replace,
- can't be built on docks.

Sure you can, if you don't mind splitting them up in smaller groups and want to risk loosing some of them. They're cheap and easily replaced, aren't they?. You can even use those 400 mini's to chaff sweep.

Check out the Stars! Calculator, it has a bombing section.

I wouldn't use smarts unless you have a CA helping you to reduce defenses with their OAs. I would use cherries+LBUs, either a 3/1 ratio, or possibly 2/2 ...
With a robber baron you might conside to only use cherries? Trying to save some factories/mines ... ? Play with the Stars! Calculator a bit.
Your bombing strategy might also vary depending on who you are up against, a HP or a -f ... Of course you can't build a different bomberdesign for each player.

1 turn kills are expensive. What you can do is bring enough cherries and get done with it. They have a set value of pop that they can kill. Add those up untill you get 1100000 and that's the number of cherries you need.

You forgot minituarization, at max tech it's this:
Hull / I / B / G
Mini / 2.5 / 0.5 / 1
B17 / 1.75 / 0.25 / 0.25
B52 / 3.125 / 0.5 / 0.375
Unless some mins are more important and cheap engines are avaible, B17 is cheapest, then comes B-52 without shields/misc then mini and then B-52 with shields/misc.
But since bomb costs are the main cost about a bomber, the actual costs differ rather slightly, B17 is 10 % cheaper than mini which is 5% cheaper than B-52.

|
As there are 4 minis per B-17, whatever jamming is used, the B-17 will take no more than 1.5-1.8 missles to destory, while the minis need 4.05.
Situation is only better with bomber chaff, but i do not think, that'll work with B-17s, no shields and little jamming for the res and bor cost(decide attractiveness), so against missles either minis or B-52 with chaff.

I think it's better to bring freighters along, you'll need one slot for them anyway, and LF can be protected with freighter/bomber chaff.

Just did it and detected something i did not know:
Defenses only act half against installation destruction, e.g. full neutron shield, 97.9%, 20 B-52 with 16 cherries destroy according to stars calc 1633 installations, while undefended planet of course losses 3200 installations.
That means that 48.97 %=0.5*97.9% of bombs are stopped from installation destruction, while against pop destruction they are fully effective.
Is stars calc correct in that respect?

I started looking for different source and in SBPosey's excel sheet (or at least a modified version of it) I found for 100 Neutron defenses:
Coverage
Normal: 97,92%
Building: 48,96%
Smart: 85,31%
So regarding the protection of installations it indeed seems that defenses are less effective ...

Ok, most things are said, most numbers crunshed... but still I would like to add a few things
First of all someone mentioned SS cloaks can make the B52 overcloaking, which I guess does not matter as any smart SS would use his stealth-bomber-hull anyway - right?
Next thing is that we speak about minefield resistance, and with one exception (the B-17 with non-ramscoop and MT cargo pod) the B-52 is the only bomber that survives a minehit (or detonation).
As the B-52 is not gateable (unless you are IT) it is a simple trade-off between gateability and minefield resistance, which - as usual - depends on the game settings. If you are IT and the enemy is SD it is simple: use the B52 - but in most cases I personally prefere the minis.
I play non-IT with IFE (so got the mizer and can reduce the main cost for the engine) most of the time - also I believe that minis have advantages in minefields - in the example of the 36ly jump I would simply split up my bombers and see that most of them arrive at the planet - no big deal
Another issue was the usage of multiple designs, so you need 2 slots for the minis. I personally (I might be wrong here) use only one design most of the time when you run out of slots. I really like to mix packets and bombers to get 1-turn-kills (or be close to that). The case that the enemy planet I plan to attack is not in 253jy from one of my massdrivers is... unlikely
If you really need more efficient bombing, then bombing with allies is the (by far) best way to go, because bombers do their job in order of player numbers (and seperatly), so low number player can "prepare" the planet with say LBUs, while the higher number player can kill it with cherry-bombers. If you want to take over the planet intact smart bombs are great with several parties bombing (it just takes too long bombing alone if defs are up).
Anyway - what I tried to say it that a lot depends on the game settings and there is no easy way to tell which is the best way to go - as usual. But wouldn't Stars be boring if it was?
I personally pray for the MT hush-bomb and meanwhile build as many mini-cherry with mizer engine as I think I need. The main reason for me to do this is the vulnerability to enemy missiles - and all other issues are much less relevant to this (usually). There are many other ways to sniper bombers - think about the battle-board-setup trick and cheap missiles on the base. If you fight in alliances you can end up losing your B-52s _very_ quickly in such a situation against a high-init cheap starbase. Something like that... To kill bombers with beamers is always expensive for the enemy as well and much harder to achieve.
Ok, not much new stuff here - but maybe I could give some more hints...
Thanks
Robert

Minis can be much cheaper. Much depends on your tech levels and whether you have BET.
Smart bombing only takes one bomb type slot.
Normal bombs designed to take out pop in one shot while leaving many factories/mines intact only takes one bomb type/slot.
Leaving factories/mines intact can be extremely powerful, your new planet can defend itself better and in a tit for tat war you are gaining as much as you lose while your enemy has to rebuild any of his gains.
I was playing as BET HE with lots of mini-colonisers with nothing in mech slot as fuel boosters/generators/minefield crash sweepers. Minis often worked the best.

Yes - as Micha pointed out, the SS cloak is the Super Stealth cloak. Not a super stealth race cloak. Obviously, anybody playing SS will simply use stealth bombers and ultra stealth cloaks - great overcloaking there.
Using a B52 with a nice 'mix' of bombs - stuff available at the weaps 14/15 time frame, lets take the following config:
B52, Interspace 10 (or Transwarp drive), 2 slots of LBU 32's, 1 slot of Cherry Bombs, 1 slot of Enriched Neutron bombs 2 shields and 2 super stealth cloaks. This is a nice mix of blasting power for a 'general purpose' bomber. (I'm not getting into 'best bomber designs' or 'best bomb mix' discussions here - just a flat description of the overcloaking potential)
The above listed design weighs 937kt. With the 2 ss cloaks the bomber is 72% cloaked BUT, more importantly, it has 262,360 cloak units! A few of these b52's will cloak a lot of smaller support ships to that same 72% - i.e. super fuel transports, some chaff, a couple freighters..... Add a couple galleon overcloakers and you can make your fleets pretty hard to find.
See my section on overcloaking in the forum. I have posted maximum overcloaker designs for several hulls.

I just took a look at the Hush-A-Boom, it specifies that it kills appx. 3 % of pop and 2 installations. There is no mention of a minimum kill value.

Yes - sorry... I was not careful enough and should have known you know very well what you are talking about - my mistake.
I guess I was confused by the "overcloaking", because when I say overcloaking I mean one ship has better cloaking than 98% and can "overcloak" other non-cloaked ships so the whole fleet still has 98% cloaking... guess from that mistake I assumed you must be talking about SS and ultra-cloaks or something... anyway - I will check out your overcloaking posts cause I did some serious tests on SD and IS overcloaking once with speed-trap-mines in nubians... Have to check if my results are ok...
And I really like the "guts of bombing" article somewhere else up there - great summary!!!
