Note 1: This = A7M2 as built, because the Navy rejected the designer's request for a larger engine. In EOS the designer's preference was honored so it is the 1 model.
Note 2: The "Operational Ceiling" is an RHS concept: it is approximately halfway between Service Ceiling and Optimum Operating Altitude. It is defined as 80% of Service Ceiling for normal piston engines; 90% of Service Ceiling for turbosupercharged piston engines;
and as 95% of Service Ceiling for jet engines or rocket engines.
Note 3: A6M2 and A5M4 get the "Zero bonus" in EOS family.

Building these spreadsheets revealed that the problem of later Japanese carrier fighter performance was no longer addressed.

In CVO and BBO, the Ki-44 III is available as a carrier fighter, because of JAAF plans to use it in that role on escort carriers. While the first of these did indeed see operational service, apparently they mainly operated Ki-76 and Ka-1 aircraft with ASW armament. In any case, the Ki-44 is not a JNAF aircraft, so the historical problem remained there.

RHSEOS family is supposed to address such issues - to the degree more rational planning might have done that. The original concept here was to simply let the Ki-44 III serve in JNAF - and indeed it was implemented that way. BUT we changed the slot to land based - so the Me-109T could serve on carriers early in the war. Thus - we defeated the idea that the later Ki-44 could address the carrier fighter problem.

When Mifune brought up the problem, I looked at the wrong file, and wrongly reported the Ki-44 III was a carrier plane. It is not - in EOS - although it IS a JNAF aircraft - ONLY for land based use.

So I revisited this matter. I remembered the A6M4 - and investigated it. We have the designer's word (long after the war) that it was for a turbosupercharged modification of A6M3. This late (third) A6M3 variation approximates the A6M5 - and the first A6M5s were A6M3s modified - before yet another wing was adopted for the difinitive A6M5. But while this results in better altitude performance, it does not seem to solve the problem otherwise.

I then examined the A7M program. This was indeed concieved in a timely way - with a 16 Shi specification - but the Navy withdrew it. It was reissued in 1942 as a 17 Shi specification. The Navy refused to honor the designer's intent engine wise - and forced Mitsubishi to build the A7M1 with a smaller engine. Tests showed the designer was right - and so then they finally built the A7M2 as he originally intended. Here we show the aircraft as A7M1 - because it is the first A7M built - although it is identical to the A7M2 except for availablity date - which is somewhat better.

An alternative possibility would be to evolve the A7M1 from the 16 Shi specification - a year sooner. But then there would be problems of engine availability - and I think the A7M1 as built would be the form it would take - a form rejected for its performance IRL - and presumably worthy of rejection by our fictional planning body (if they could properly estimate performance). Nevertheless, it is a better fighter - 310 knots (vice 288 knots for A6M2) - better protection and armament - and maneuverability.

NO possible aircraft can rival the range of the A6M2 - except oddly a variation of A6M3 - which has even more range!

Bottom line: The table above is correct in all respects for aircraft data per se in all forms of EOS. However, the name change and date change for A7M will only be in sync with 7.7873 (not yet issued) and later releases. There are at this time no plans to update Level 5 or Level 6 until after a Matrix update. However, the files at source are updated, and if we ever update 5 and 6 - this change will apply to EOS scenarios in them as well. The aircraft data for A7M does NOT change - just the name (from A7M2 to A7M1 in EOS family) and the date (from 2/45 to 8/44).

Note 1: In EOS the A7M1 is built to the 16 Shi specification - which was cancelled. The A7M2 is built to the 17 Shi specification without the need to develop the lower powered A7M1 first - which is what happened IRL. Better planning moves up the availability.
Note 2: The "Operational Ceiling" is an RHS concept: it is approximately halfway between Service Ceiling and Optimum Operating Altitude. It is defined as 80% of Service Ceiling for normal piston engines; 90% of Service Ceiling for turbosupercharged piston engines;

Note 3: A6M2 and A5M4 get the "Zero bonus" in EOS family.

Above is the final final final form for RHSEOS Japanese fighter statistics.

The A7M2 is back with its original name. The A7M1 is present - done to a 16 Shi specification - so a year earlier -
and replaces the A6M5. The Ki-45b is replaced by a variation of the Ki-61 - the one with German 20mm guns.
This aircraft follows Me-109 in production - with the same engine - and in turn is followed by Ki-64 - with the same engine - a unique German inline one.

ORIGINAL: el cid again

Bottom line: The table above is correct in all respects for aircraft data per se in all forms of EOS. However, the name change and date change for A7M will only be in sync with 7.7873 (not yet issued) and later releases. There are at this time no plans to update Level 5 or Level 6 until after a Matrix update. However, the files at source are updated, and if we ever update 5 and 6 - this change will apply to EOS scenarios in them as well. The aircraft data for A7M does NOT change - just the name (from A7M2 to A7M1 in EOS family) and the date (from 2/45 to 8/44).

Hi el cid again,

Do you have plans to release a 7.7873 upgrade to EOS prior to December or is the plan to wait until after the Matrix update?

My plan - shaky - is to release today. The version number is 7.7872. I regret that I will also release updates for Level 5 and Level 6 - not quite at the same level - but in order to keep aircraft and certain other things in sync (as with art pointers). They will be 5 & 6.7863.

Looks like RHSEEO may be delayed by a day or so - at a minimum.

Otherwise everything will release tomorrow or the next day. I work today - but not tomorrow - and this should be it - for everything.

There won't be more updates until after Matrix update - whenever that is - and I don't know (and probably they don't know) when that will be in any absolute sense. [Updates need to be tested and possibly corrected before release] But the rumor in the Forum was sometime in December. I figure we may do an update a few days after they do - as this update may affect some things which require we make changes.

Which fighters are carrier capable?
A5M, A6M, A7M, Ki-44, Myrt. Any more?

It depends on the scenario:

In CVO and BBO Ki-44 is carrier capable - but in EOS family it is not.

In EOS family Me-109 is carrier capable - but it is not even in CVO or BBO families.

A5, A6, A7 are always carrier capable in all scenarios - BUT

in CVO and BBO families there are more kinds of A6s and fewer A7s - which appear very late

but in EOS family from the next release A7s will appear sooner (and in 2 versions) -

one on a 16 Shi specification that was cancelled (costing a year) and the other on a 17 Shi specification which did not have to wait for the 1 model to develop on a by then too underpowered engine.

Myrt is not really a carrier plane at all - although it was designed as such - IRL. It appears in small detachments on larger carriers late in the war - IF there are any larger carriers late in the war. [IRL the carrier force was abandoned after a certain point and plans were not implemented]. This is similar to the early war Kate recon variant - which is only found in small detachments in EOS family. IRL the concept was developed, rejected, and then reimplimented again with the D4Y1-C recon plane - which had one detachment at Midway - and flew in small units thereafter. In EOS our planners decided to implement the original idea - and to upgrade to the D4Y later.

Note that the A7M1 is not a good performer - but it is a much better armed and protected aircraft than any A6 -
a stopgap waiting for the development of the engine which makes the A7M2 a potential star. JNAF had the forsight to know it would need a follow on carrier fighter - and then it shot itself in the foot - twice! The first time, it decided it could wait a year - and would invest design resources on variatios of A6 - bad mistake. The second time, after that delay, it failed to listen to the designer, and insisted on using a less powerful engine than was ideal for the weight of the airframe - and got a poor preformer no longer acceptable by the time it could be fielded. Finally it let the designer do what he wanted to do - and it was too late for the war.

When will the next update be published?

Plan: Today (but I am half a world away from you remember - GMT plus 9 hours)

Otherwise Tomorrow

EEO will be Tomorrow in any case
