It depends on whether the DT#1 refers to the first test of the JSF on WASP or the first test of the JSF with Thermion on the WASP.

btw AG, I knew it's more than just paint.

ps. The pics show Thermion as beige, not dark. Could they paint over it or would they mix some sort of dye into it?

That is true also, though it's been 16 months since that PDF was created and we know that the flight deck was repainted at least to redraw the tramline markings to accomodate the extra wing span of the F-35b and then there are throw away lines such as this doing the round:

For the past several weeks, Wasp upgraded part of its flight deck to land fixed-winged aircraft during this underway period for the AVCERT facilitated by Afloat Training Group (ATG).
Sailors No. 1 Mission: Return USS Wasp to Sea

So it's definitely possible they are testing both at the same time...

Amy from AW scored a day on Wasp and found out that
"the rear portion of the deck had been poured at a later time than the front, accounting for the difference in color. Both are made of standard nonskid material used on ship decks. However, there is a small portion in spot 9 of Thermion,
The Thermion is in the area where you see the lighter yellow centerline. "

Not sure as the article says 90. Maybe the yellow area is the 90 part. If you look closely at the original photo (attached) you will see a slightly lighter area where my red square is. Notice that the black lines that run the length of the deck do not pass through the area that I outlined.

Does anyone know how far apart the tie-downs are spaced on the deck of the Wasp?

--Edit--
A couple of quick calculations (based on a tiedown every 5 ft.)

The yellow section is about 90ft² (less than 1 tiedown [~4.5 ft] squares in width and 4 deep)

The whole section I outlined is about 600ft² (a grid of 6 wide x 4 deep tiedown squares)

It looks like it's just the yellow area that is Thermion.

Isnt the Thermion only on the yellow line.

Because what you have outlined there is closer to 900sq ft..
And only a small patch of it under the touch down point. Since without a ski jump the take off mode for the F-35B on an LHD is with the nozzle down the rest of the tram line is going to get a solid workout without the thermion. After 60+ landings and takeoffs in a few days it all looks pretty good. Chalk down the melting decks and the like to the rest of the F-35 hate crime.

An Update on the F-35B Transition | SLDInfo

The much reported problems with heat on the deck and other issues appear to be non-issues. Noticeably, the F-35B needs only about 50% of the WASP deck to take-off, which is a clear indication that there are many ships on which this bird can land and take-off.

Kudos to the Program for what appears to be an outstanding sea trial for the B. Now if only they can work out the bug with the night vision on the HMD...

VSI recently won a development contract to continue development of their helmet solution so all is not lost. IOC isn't planned for most models until at least 2016, so they've got years left before this shortfall will actually affect capability.

I would not be surprised to see this "massive" hurdle cleared well before any user gets close to IOC and just like the "exploding concrete and melting decks" hyperbole, turn out to be just more hot air the naysayers are promoting, hoping that someone listens to their rubbish opinions.

Just my 2 cents.

The whole flight deck has to be stressed for static load of the CH-53E. Which is 33 tonnes on six wheels. That isn’t including the strength to resit a CH-53E and maximum downwards velocity before impact. This is a considerable extra load in the landing area. 18 tonnes spread other two much larger down blast patterns (compared to the wheels) is not going to be a serious challenge to a deck with strength to land on CH-53Es.:rolleyes:.

No arguement on static load am more interested about the dynamic loads applied by the jet wash which will be concentrated below the jet pipe and ducted fan.

And aluminium has much higher reflectivity than steel so it is harder to heat up.

No one is talking about flying in and out F-35Bs on a regular basis (well I’m not) but the heat loads from lily pad type operations are not going to be excessive. Said lily padding is not going to be a part of any typical operational mission but it also won’t be an end of flying emergency type recovery. It will be much like that one SHAR that had to come down on an LPD deck during the Falklands. It flew home the next day when otherwise it would have ended up in the drink. It just provides an extra level of safety in the argy bargy of expeditionary operations.
Again we are looking at the same point and my comments focus mainly on the suggestions (not by yourself) that LCS could operated F-35B ..... rather than the "oh bugger we have to land issue". Sorry if this came acros the other way.

Aluminium has higher reflectivity but is more readily stress beyond it elastic limit and heat dow not help.

As I said..... just observations.

Here is a graphic from the above Nikkei article (thanks Slowman for providing).

The first category is "Operability/Maneuverability", the second category is "Industrial Participation", the third category is "Relations with the US".

Biggest surprise for F-35 haters is that it placed the F-35 above the F-18 and Typhoon in "Operability/Maneuverability"

Can't interpret those circles and triangles so I'll take your word for it, Spudman. The "X" given to the EuroFighter I assume to be a bad thing.LOL. I'd expect Boeing to get more points for industrial participation.

Interesting how quickly the Japanese seem to be going about their evaluation compared with the plodding pace characterizing the Indian MMRCA deal.

Tks slowman, The first category is "Operability/Maneuverability", the second category is "Industrial Participation", the third category is "Relations with the US".

I think highest = double circle, then single circle, then X , and lowest = triangle

gf, yep one and the same idiot, but he did put up the pic and then ranted how japan could be so silly

spud, yeah it may well be that way but I put japan/uk relations above the f-35 Industrial Participation with japan, perhaps there will be more explanation later

who can forget this 17 page gem.. :dbanana
US demands Japan $10 million for the access to F-35 capability information
TOKYO —The U.S. government has asked Japan to pay around 1 billion yen for information related to the capabilities of the U.S. F-35

Well, the US DoD is pushing Japan into the arms of Eurofighter...said slowman
That's probably because they were only selling the "export" version of the F35 with remote software kill switch and added radar reflectors :)
