I'll bite - where is F135 listed as a '43,/28k'? I can answer 'where' but you will have to ask LM 'why'.

Any idea, why is F135 in March 2012, listed as 40k/25k lb class engine, instead of 43k/28k?

Maybe 40k/25k is what the engine must do, but we all know it can really do is 43k/28k.

PW has 43k lb listed on their site > http://www.pw.utc.com/products/military/f135.asp
Didn't quite follow, so do you have any idea when that changed?

At the link 'cola' provided the info is this: (under the 'characteristics' tab). 'TEG' will probably have an explanation whilst 'g3143' seems to be close, perhaps engine control software limits engine output for prolonging engine service life? Anyway:

Thanks SWP. My Acrobat Reader 10.1.3 generates an error message on page 3 indicating perhaps that information is missing from that page. Anyway here is another example page (edited) from same PDF. Page 3 (with error message not shown) also attached. Plus now 'candidate weapons for Block 4' page attached.

Page 3 looks like that for me and I get no errors (version 10.1.3)

OK thanks. Probably a 'font thing' I'll mess around with whatever I can (currently testing Acrobat 11 which generates same message also). Using Windows 7 64 bits and I can test it in Windows 8 wappidywap 64 bits candidate BETA release. Too much info I'm sure. Very Happy
