41m or 41.5m, this is conclusion based on the following images.

Yes, and CSIS had since revised that estimate down to 40m in subsequent reports and imagery.

40m also corresponds with the higher resolution google imagery measurements that we've been able to have over the years.
In addition, 003 is some 15 meters shorter than Ford/Nimitz as well.

The physical measurements of 003, combined with the many years of rumours of 003's full displacement going back to the 2010s (none of which suggested that it would displace 100,000 tons, and which instead it was consistent that its displacement would be around 85,000 tons or even directly compared to the Kitty Hawk class), means until there is evidence to the contrary, there is no basis for us to speculate that 003 has a full displacement in the 100,000 ton category.


Please don't continue this line of discussion further, just accept that for now, our overwhelmingly best estimate for 003's full displacement is that it is 85,000 tons, some 15,000 tons lighter than a Ford, based on its external measurements of its length and waterline beam, as well as the years of consistent rumours.


This is going to be my last post on the matter in this thread.

I just want to remind you that full displacement of 85,000 tons cannot be estimated only according to length and waterline beam. For example, 1m of draft can cause huge displacement gap.

Well, get this thread back on track and please continue your excellent work.

We have an almost perfect measurement point, the unfinished 1143.7 class carrier, which in some way is almost a half-sister to 003.

Her dimensions are within meters of what was known about 003 (just a bit smaller in everything), and her displacement (79'758 t full per design) is very well known.
So 003 realistically won't be below that number, and won't go too far away from it either.
85'000 is, above all, just reasonable.

How is 003 'almost a half sister' of a non existent carrier? Did China buy the plans?

They were developed from more or less the same starting point (Liaoning), they have very similar dimensions. Stepsis is still a sis.
And yes, while it isn't exactly verified, most probably her plans also went to China.

We've debated long and hard about whether 003 can be narrower or needs to be as wide as a Nimitz-class aircraft carrier. We looked at pictures and made drawings. Everything can be found here in the forum, I don't bother to dig everything out. In a few weeks, the next unbeliever will come and have everything chewed out again. If you want to know how it really is, you can find out for yourself.

... and question and challenge the notion that 003 is conventional, instead of nuclear ... lol.

So, my view is that I think the PLAN had likely began designing their CVN a number of years ago, derived from the 003 design. Keep in mind the design of 003 would've been already largely set in stone years ago now, probably sometime after 2015, with only the minor redesign for the EM catapults.
In the case of the CVN, they could've started its design work (derived from 003) anytime in the mid to late 2010s.
I suspect the design of the CVN at this point, as of mid 2022, is likely nearly complete, if not complete.

.... However, I believe the design work for the CVN (again, as derived from 003) would've likely still taken a good 3-4 years.


Going from a conventional CV to a CVN is already a fairly significant difference, even if your hull was already designed around the dimensions of the reactor compartment. You'd still need to ensure that the rest of the hull's structure is adequately redesigned, such as ensuring you have sufficient berthing for how much crew your CVN now needs, ensuring that you can use up any new free space efficiently (such as more volume for aviation fuel, if any), slimming down the size of the island based on no need for an exhaust vent running through it given your ship is now nuclear... etc.

But we aren't just talking about going from a "conventional CV" to a "CVN". It is more accurate to say that they are going from "conventionally powered 003" to "nuclear powered 004".
That is to say, I think we should all expect 004 to have some significant differences and improvements over 003 (even if 004 is derived from 003), which would require substantial time for redesign/expansion:
- adding another catapult on the waist (for 4 catapults rather than 3)
- slimming down the size of the island and perhaps repositioning it to the rear
- redesigned flight deck including lengthening of the overall flight deck and ship length (which requires lengthening of the overall hull), and widening parts of the flight deck too, for better deck handling
- likely adding another elevator to the ship, namely on the port/aft position
And of course, all of the modifications in relation to adding nuclear propulsion:
- replacing the conventional steam turbines with nuclear propulsion
- electrical generation overhaul associated with said nuclear propulsion
- vents and piping modifications/removals
- redesign (or expansion) of ship's aviation fuel capacity


.... all of the above, for a notional 004 derived from 003, is not something that I can see take less than 3-4 years.
I realize that your central view is that 004 is a design derived from 003. That is 003 is the base, 004 needs to do the change, therefor extra design work.

On the other hand, I think that it is possible that PLAN started 003 and 004 in parallel. PLAN may want a CVN as its target ship. But anticipating that their reactor design is new while their conventional power-plant is ready, so PLAN ordered 003 as a "backup" to fit the potential gap or delay of 004. They have two design works started simultaneously around the same displacement and armament, but around different power plant. In this scenario 004's design work isn't anywhere behind 003. The only time gap is the reactor's readiness.

That is also possible.

The important part, which I think we both agree on, is that if they want to start building 004 anytime in the next few years, it means its design should already be completed
