CHS 1.07 Suggestions so far

You mean there are others? [&:]

[el cid again]

Two things - remember that each phase (two per day) is 12 hours long. Second, as of a recent patch the number of escorts conducting an ASW attack has been limited to 4. The number contributing to detection is unlimited (IIRC).

Interesting. Are all escorts identical in detection capability? Or identical by type (DD, PC, etc)? In a way the number contributing to detection should be unlimited - BEFORE the engagement - simulating the screen. But AFTER the attack begins it is not important how many you have after a certain number. And only ONE ship can attack at a time. I said two - one to track and one to attack. It too is crude and oversimplified, but you must do something short of put a fleet to sea. What about airplanes? A single observer plane with no weapons or sensors vastly increases the chance for success in an ASW attack. And forces the subs to submerge if they are not.

Not sure if it's been mentioned but in going over the Chinese Army OOB for the leaders, it looks like there are some duplicated Chinese Corps but they are in different locations but same name - 36th, 49th, 93rd & 96th. Not sure if the one or both of the 93/96 should be Divs as my last CHS OOB had a 93/96 Chinese Corp & 93/96 Div unit. Also the 10th Chinese Corp has a typo, in DB it's 10th Corp so in game it comes out as 10th Corp Corp instead of 10th Chinese Corp.

Checked the database I still have and the 36th, 49th, 93rd & 96th are all correctly listed as separate Divisions and Corps and are not duplicates. The vast majority of Chinese units were repositioned to their historical starting position. So the 96th corps will be in a different starting position than it had in previous editions. Yes the 10th corps is a typo and should be the "10th Chinese" instead of the "10th Corps".

As far as my absence from WitP... I became frustrated with the bugs and felt that the game was taking up much too much of my life for me to devote anymore time to it. The bugs included disappearing units and Task Forces that would start to load one turn and start to unload the next...

That's the point of noting that it's a 12 hour phase. 'An' attack by (up to) 4 escorts is actually a series of separate attacks.

I hear you. Keep things in balance! Glad you're around.

Joe,

The engines are not a typo nor is the George arrival date. The N1K1 was quite ready to fly and kick some allied butt except it didn't have an engine.

If you the player do not accelerate production of the engines you will not get aircraft.

I will admit i was hoping that the production system worked like BTR where Germany could build and store airframes for use when engines were available. I loved being able to build sepperate airframes.

Hello hello hello !!! Welcome back !!!

Ah ... btw don't know how to accelerate production of engines !? !?

Yes it is. But it might well be the SAME escort over and over. Consider the case of USS England. She had a whole ASW group in support - but they let her make the runs - because she was so good at placing them well. [USS England did in an entire patrol line in a few days and holds the all time record for sub sinkings. Usually an escort has ZERO kills of subs. Usually is seems random if this one gets a kill. But with USS England it is clear they DELIBERATELY got kills.]

The number of attacks in 12 hours is finite. A late war ship might have over a hundred DC and other weapons - while an early war ship might only have charges for 3 runs. But the total number of runs in 12 hours (assuming no ammunition limit because you have enough ships) is constant - possibly in the neighborhood of 12. [It depends on the average time to reacquire the target plus the time to get into position for the next run.] The number of ships (over 2) does not matter - IF you have 2 the chances of his escaping undetected from the noise of your run are poor. But it DOES matter if there is only one escort, and it DOES matter if you have air observers or not present.

I responded (only) to your point that ASW attacks should be limited to 2 because only 2 ships can attack at once. Because it is abstracting a 12-hour pulse, 4 ships can certainly attack.

There are limits to the detail of the ASW combat model that we are dealing with.

[Ron Saueracker]

From the sounds of the reworked ASW model (not air ASW yet but hopefully) I think I'm satisfied. People keep harping that I'm wanting tactical in a strategic game. Well, if one is going to model a game down to individual planes, I can't help but wonder why some might want the tactical feel abstracted at least. The new model sounds like it does this for ASW. Good enough and on to the next issue.

I find it remarkable the game tracks single .30 and .50 cal hits, pilots and commanders by name, and then claims NOT to be a tactical level sim. The air combat model (which works for less than 50 vs 50 plane encounters better than any other yet devised) tracks INDIVIDUAL planes. [Further, it USED to be better, until Matrix listened to its Forum, and REMOVED ammo limits from fighters: a fighter cannot go on shooting all day long in real life - but WE imposed that on the modely by asking for it!]

I don't remember any ammo limits...where did you see this? Ammo limits do seem to be something that is sorely needed.

[Ron Saueracker]

Just a thought...

Before pushing for Nik's A2A mod being inserted into the CHS, shouldn't it be tested more? I have not seen how it performs with large numbers of opposing aircraft, and this is where the biggest problem lies. I'd like to see a test where the exact same number and type of planes (ideally the size of the Artez AAR battle I utilized in the main forum in that CAP ribbing thread) are first tested using stock values and then using Niks.

Be cool if it was a huge improvement.

Ancient history - so ancient I had forgotten about it until Joe reminded me. It happened in the days UV was the vehicle for developing the engine. The Forum said "fighters are not effective enough" and specifically asked the ammo feature be removed. The dissenters were not numerous enough - and the forum got what it asked for.

In this case Matrix original code was RIGHT, and too bad they listened to us (although I am assuming guilt by association only - I personally did not agree with removing ammo limits - which I ALWAYS use if I do a model). A fighter plane in WWII typically could shoot three times at full value and one more time with a short burst. Bombers had more shots - naturally - and highly skilled pilots might get a few more bursts than green ones could - but that is the general principle. Letting a fighter shoot down 10 bombers is nuts.

Well maybe, maybe not, Ron, but this is yet another fix that needs to be tested further. As it stands subs are now going to be extremely difficult to "hard kill". What it will do is limit the damage of uber-asw groups. Will have to see if it gives any kind of historical results, or if it is just a leaky badly applied band-aid.

Notes:
Note 1: The first batch of 24 model 32 production machines was made in 6/42.
[Appendix F, Zero, Robert C. Mikesh (Forward by Saburo Sakai)]
Note 2: The first batch of 76 A6M5 production machines was made in 8/43. Ibid.
Note 3: The first batch of unknown size was made in 10/44. Op. cit. See also
text discussion on p. 90, same source.
Note 4: The first prototype completed in 4/45. The A6M5 went from prototype to
production in 2 months. It is optimistic to assume operational status in 8/45. Included ONLY because this aircraft ALREADY part of CHS.
Note 5: The first batch of unknown size was made in 7/43. Francillon.
Note 6: This aircraft was prematurely sent to the Philippines for operations in 1/44,
in spite of problems with engines and undercarriage that normally would not
have permitted service acceptance. Actual IOC used. Francillon.
Note 7: This aircraft was plagued by engine problems in spite of being sent to an
operational unit to such an extent production was long restricted. Francillon.
In spite of this, the actual IOC is used.
Note 8: While the first flight did not occur until 8/45, the first prototype completed in
4/45 and under normal conditions could have occurred then. Using the logic of
Note 4 above, we add 4 months to 4/45 to get 8/45. Francillon.
Note 9: The first production batch of unknown size was made in 8/43. Francillon.
Note 10: The first production batch of unknown size was made about 5/44. Francillon.
Note 11: This transport is intermediate between a Ki-34 and a Ki-57 in performance. The
Ki-56 is derived from the LO (Lockheed 14). If DNKKK (All Japan Air Lines) is
it has about 32 machines (including 7 similar performing DC-2s). Francillon,
Gunston and Weal.
Note 12: Historical production delayed by an earthquake not imposed on players! This
IOC date estimated on the same basis as Note 4 above.
Note 13: Probably the worst bomber in the game, even worse than the Ki-36! This type added for use in ASW groups on Army carriers – in which role it might be useful.
It COULD be added to certain JAAF HQ groups as well – for recon. Francillon.
Note 14: Accepted for production in 3/43. Production probably began that month (as the
failed D4Y1 was already in production). Francillon.



Note 15: Added to permit creation of Army carrier air groups. This aircraft may also be
used in regular fighter groups – but historically the Ki-84 was used instead.
This aircraft was also intended for Army escort carriers. Sources differ about the production of this aircraft. IOC estimate based on 6/43 flight. Bueschel & Francillon.
Note 16: Pre-production until 4/44. Production “began in the spring” interpreted as 5/44.
Francillon.
Note 17: The first production batch of unknown size was made in 6/43. Francillon.
Note 18: The first production batch of unknown size was made in 5/44. Francillon.
Note 19: The first production batch of unknown size was made in 8/43. This aircraft was
designed to function as a dive bomber. It was code named as a fighter by the
Allies and was capable of marginal fighter operations. Francillon.
Note 20: The first production batch of unknown size was made in 7/43. Francillon.
Note 21: IOC based on first flight in 10/44 using the logic in Note 4. Francillon.
Note 22: IOC based on first flight in 8/43 using the logic in Note 4. Problems with the
hydrolic system and engines prevented combat use until 1945, but this is ignored.
Note 23: The first production batch of unknown size was made in 6/44. Francillon.
Note 24: The first production batch of unknown size was made in 8/42. Francillon.
Note 25: The first production batch of unknown size was made “in the spring of 1944” –
interpreted to mean 3/44. Designed to dive attack subs. Had MAD. Francillon.
Note 26: First mission in 3/42. Production began about 1/42. Francillon.
Note 27: Production began in 1943 with one previous H8K1 conversion. Francillon.
Note 28: Represents navy and civil variants of Ki-34, including AT-2 and DC-2.
Note 29: 4 machines built and served to this specification. Francillon.
Note 30: The first production batch of unknown size was made in 10/44. Francillon.
Note 31: IOC based on first flight in 8/45 using logic in Note 4. Francillon.
Note 32: For bomb load data see Bueschel. Other data confirmed by Francillon.
Note 33: 16th Sentai took first delivery of operational machines in 8/42. Guns were
all Allied types; added missing guns (tunnel 20mm and rear). Francillon.
Note 34: The first production batch of unknown size was made in 4/44. Francillon.
Note 35: IOC based on actual issue to 23rd Fighter Company. Bueschel.
Note 36: The first production batch of unknown size was made in 10/44. Francillon.
Note 37: IOC based on first flight in 11/33 using logic in Note 4. Francillon.
Note 38: IOC based on transfer of 22nd Sentai to China for operations. Francillon.
Note 39: IOC based on actual issue to 244th Fighter Sentai. Bueschel.
Note 40: The first production batch of unknown size was made in 10/44. Francillon.
Note 41: The first production batch of unknown size was made in 2/42. Francillon.
Note 42: IOC based on actual issue to JNAAF 98th Torpedo Regiment. Bueschel.

Originally for the "Fairy B-29" threat, but I found it more appropriate here.

XXI Bomber Command flew 26,401 effective sorties, dropping 157,985 tons.

XXI BC: 157,985/26,401 = 5.98 tons pr. sortie

Presuming they're short tons, that's 11,960 lbs.

In CHS, B-29's have a load of 14,000 lbs. Japan is extended range from the Marianas, meaning that the effective load delivered pr. B-29 will be 7,000 lbs, or 58.5% of the historic average.

Timtom,

The B29 load will stand in CHS. You are failing to look at all the data. The only way the US got the lift they did with the B29 as an average for the war was by restricting max altitude so you are not wasting fuel climbing and by tearing out 90% of the guns. Early, armed B29 sorties flying at high levels averaged 7-8000lbs.

From the sounds of the reworked ASW model (not air ASW yet but hopefully) I think I'm satisfied. People keep harping that I'm wanting tactical in a strategic game. Well, if one is going to model a game down to individual planes, I can't help but wonder why some might want the tactical feel abstracted at least. The new model sounds like it does this for ASW. Good enough and on to the next issue.

Well maybe, maybe not, Ron, but this is yet another fix that needs to be tested further. As it stands subs are now going to be extremely difficult to "hard kill". What it will do is limit the damage of uber-asw groups. Will have to see if it gives any kind of historical results, or if it is just a leaky badly applied band-aid.

I am under the impression that there is a possibility of a critical hit on subs by ASW devices. Given the number of hits that are now being scored but with low yield affect I am hoping the sub losses will fall in line with DC expenditures.

Notes:
Note 1: The first batch of 24 model 32 production machines was made in 6/42.
[Appendix F, Zero, Robert C. Mikesh (Forward by Saburo Sakai)]
Note 2: The first batch of 76 A6M5 production machines was made in 8/43. Ibid.
Note 3: The first batch of unknown size was made in 10/44. Op. cit. See also
text discussion on p. 90, same source.
Note 4: The first prototype completed in 4/45. The A6M5 went from prototype to
production in 2 months. It is optimistic to assume operational status in 8/45. Included ONLY because this aircraft ALREADY part of CHS.
Note 5: The first batch of unknown size was made in 7/43. Francillon.
Note 6: This aircraft was prematurely sent to the Philippines for operations in 1/44,
in spite of problems with engines and undercarriage that normally would not
have permitted service acceptance. Actual IOC used. Francillon.
Note 7: This aircraft was plagued by engine problems in spite of being sent to an
operational unit to such an extent production was long restricted. Francillon.
In spite of this, the actual IOC is used.
Note 8: While the first flight did not occur until 8/45, the first prototype completed in
4/45 and under normal conditions could have occurred then. Using the logic of
Note 4 above, we add 4 months to 4/45 to get 8/45. Francillon.
Note 9: The first production batch of unknown size was made in 8/43. Francillon.
Note 10: The first production batch of unknown size was made about 5/44. Francillon.
Note 11: This transport is intermediate between a Ki-34 and a Ki-57 in performance. The
Ki-56 is derived from the LO (Lockheed 14). If DNKKK (All Japan Air Lines) is
it has about 32 machines (including 7 similar performing DC-2s). Francillon,
Gunston and Weal.
Note 12: Historical production delayed by an earthquake not imposed on players! This
IOC date estimated on the same basis as Note 4 above.
Note 13: Probably the worst bomber in the game, even worse than the Ki-36! This type added for use in ASW groups on Army carriers – in which role it might be useful.
It COULD be added to certain JAAF HQ groups as well – for recon. Francillon.
Note 14: Accepted for production in 3/43. Production probably began that month (as the
failed D4Y1 was already in production). Francillon.



Note 15: Added to permit creation of Army carrier air groups. This aircraft may also be
used in regular fighter groups – but historically the Ki-84 was used instead.
This aircraft was also intended for Army escort carriers. Sources differ about the production of this aircraft. IOC estimate based on 6/43 flight. Bueschel & Francillon.
Note 16: Pre-production until 4/44. Production “began in the spring” interpreted as 5/44.
Francillon.
Note 17: The first production batch of unknown size was made in 6/43. Francillon.
Note 18: The first production batch of unknown size was made in 5/44. Francillon.
Note 19: The first production batch of unknown size was made in 8/43. This aircraft was
designed to function as a dive bomber. It was code named as a fighter by the
Allies and was capable of marginal fighter operations. Francillon.
Note 20: The first production batch of unknown size was made in 7/43. Francillon.
Note 21: IOC based on first flight in 10/44 using the logic in Note 4. Francillon.
Note 22: IOC based on first flight in 8/43 using the logic in Note 4. Problems with the
hydrolic system and engines prevented combat use until 1945, but this is ignored.
Note 23: The first production batch of unknown size was made in 6/44. Francillon.
Note 24: The first production batch of unknown size was made in 8/42. Francillon.
Note 25: The first production batch of unknown size was made “in the spring of 1944” –
interpreted to mean 3/44. Designed to dive attack subs. Had MAD. Francillon.
Note 26: First mission in 3/42. Production began about 1/42. Francillon.
Note 27: Production began in 1943 with one previous H8K1 conversion. Francillon.
Note 28: Represents navy and civil variants of Ki-34, including AT-2 and DC-2.
Note 29: 4 machines built and served to this specification. Francillon.
Note 30: The first production batch of unknown size was made in 10/44. Francillon.
Note 31: IOC based on first flight in 8/45 using logic in Note 4. Francillon.
Note 32: For bomb load data see Bueschel. Other data confirmed by Francillon.
Note 33: 16th Sentai took first delivery of operational machines in 8/42. Guns were
all Allied types; added missing guns (tunnel 20mm and rear). Francillon.
Note 34: The first production batch of unknown size was made in 4/44. Francillon.
Note 35: IOC based on actual issue to 23rd Fighter Company. Bueschel.
Note 36: The first production batch of unknown size was made in 10/44. Francillon.
Note 37: IOC based on first flight in 11/33 using logic in Note 4. Francillon.
Note 38: IOC based on transfer of 22nd Sentai to China for operations. Francillon.
Note 39: IOC based on actual issue to 244th Fighter Sentai. Bueschel.
Note 40: The first production batch of unknown size was made in 10/44. Francillon.
Note 41: The first production batch of unknown size was made in 2/42. Francillon.
Note 42: IOC based on actual issue to JNAAF 98th Torpedo Regiment. Bueschel.
