RHS AA!

But at least your replacement pilots are good enough to land again once they take off...

It is going to be rough, without a doubt. Once we get into late 1943 I should have enough air units to be able to rotate/train and build up experience. By then you will have won the war. The ahistorical lack of attrition needed sorting, but flak is a blunt instrument. A pilot loss results to cover the fact that airframes can't be written off. Not good with the sh1te Allied replacements. I shall be crying lots and may turn to alcohol...

Well we might as well dive in instead of pussy-footing about the pool. I sent you a response regarding suprise being off. I still think with half the Nip navy @ Kwajalein suprise should b off.

Is there a special medical name for fear of flak?

Common sense.

So far I am in may 1942. My experience i.e. vs a strong point like Singapore: the Japanese usually lose (AA losses only) like 2 or 3 planes per mission. The planes fly of course at high altitude: 17.000 or 18.000 feet. I don't think the AA model is a mess. If I well understood, Carl's point is about the Japanese naval AA (too strong in his opinion, right?). I could not test that since so far no big allied air attack vs a big Japanese surface/air combat TF.

Mike and I are going for EOS. Despite any issues I have the game is brilliant and I cannot resist. [:)] Is the design now stable enough for us to be able to get all the way through without having to face restarts?

If only

If only you had not brought up this AAA stuff! I will do a microupdate of divice files to address it today or tomorrow.
Otherwise, no changes contemplated. The AAA will be slightly better - more consistent with the data. But not at all tamed - although a few are now decreased - most eratta increased range, altitude or accuracy!

Japan - Adm Yamamoto specifically long before WWII - decided NOT to use armor - as a way to get range. It was brilliant - but ultimately it didn't work out very well. Still - they KNEW the bombers were not armored (Ki-51 excepted).
So they flew ABOVE the flak at Clark and other places. [They cannot do that in many places due to better guns - but the higher they fly - the less effective the AA is]

You DO have the option of being respectful of flak. And there is NO need to fly at 5000 feet- where even 25 mm guns are effective! Even AI flies at 6000 feet. Even barrage balloons work at 5000 feet. All you are evading is .50 cals and .30 cals.

Continuing to work on AAA - I have managed to make a few things more consistent (i.e. the same device on land and sea should be identical in performance) - and I have added light and medium AAA. These use different scales - to make the AAA ratings easier to understand. It looks to me like the basic data is sound - and if you take these devices and apply them to ships and task forces - the AAA values make good sense. Sometimes the data differs from what you see in references - this is mainly the case when fusing limits ceiling. And effective ceiling defines range in RHS: range = ceiling divided by 3000 (greatest integer function). The only exceptions are very heavy guns - where surface range is their primary mission - ceilings are very low - and ROF (i.e. effect) is also very low.

Note 1: Except for Very Heavy DP guns, RHS AA gun range is ceiling divided by 3000, rounded to the nearest whole number.
Note 2: WITP Range is in thousands of yards.
Note 3: WITP ceiling is in thousands of feet. RHS uses effective ceiling rather than absolute ceiling.
Note 4: RHS uses effect = shell weight for HE and AA fragmentation type shells, but 2/3 of shell weight for all guns which have AP or SAP shells.
This is mainly for use in surface battles. For AA combat, larger effect values are probably meaningless: they will kill the target regardless.
The question that matters is: can the target be hit? The RHS AAA value scales the answer to this question objectively.
Note 5: RAN, RIN, RNZN, Commonwealth navies and RTN often use RN weapons.
Note 6: RTN often uses IJN weapons.
Note 7: Late war Soviet vessels often use USN weapons.
Note 8: 6 in/55 M1930 and 15 cm Type 5 AA Gun are true AA weapons vice Very Heavy AA weapons, and are rated as such.
