Delta IV Heavy already does 27 tonnes to LEO. LM-5 is the Chinese response to that.

Wow, which mission?I didn't meant to imply that DIVH had actually launched such a heavy payload. Only that it does has such capability and thus LM-5 won't be the most powerful rocket, at least to LEO. GTO depends on the Chinese definition of GTO. DIVH does 14.2 tonnes to 1,800m/s and 10.1 to 1,500m/s GTO.BTW, NROL-49 and NROL-65 did launched to LEO and DIV M(5,4) can do 11.5 tonnes to SSO, so they were surely heavier. Atlas V551 can do 15, so they might be even heavier.LM-5B is tasked with launching the space station modules, which are probably more than 20 tonnes each. Something that Proton has done a lot, but USA only did with the Shuttle. But could easily do with Delta IV Heavy, Atlas V and will be able to do with Falcon Heavy and Vulcan or the OrbitalATK solid LV.So, LM-5 will be up there with the big boys, but is nothing Earth shattering.
Delta IV Heavy already can do 28.8 tonnes to LEO, according to their Payload Planning Guide. LM-5 is the Chinese response to that.

You are leaving out the lone Saturn V launch with Skylab 1 (Skylab A).

The LM-5 needs a certain capability because their space projects match US and Russian space assets. Thus, LM-5 had to at least match Proton, Delta IV, Atlas V and Shuttle payload. The LEO capability is up there with Proton, DIVH and Shuttle (give it or take it) and the GTO is about the same as the DIVH.

I don't like to over quote messages, but the context was of activated launch vehicles at LM-5 debut. FH will probably surpass it and SLS will make it look like a medium launcher. But that was not the context of the original post.In other words, it is not a response, it's China building a capacity they need to develop their own objectives. It's an engineering choice, not a mythical keeping up with the Jones approach.

Any reports of what Shijian 17 will be doing?I hope there won't be a few hundred "orbital spam" cubesats as well!
SJ-17 Shijian-17 to be launched on the maiden flight of the CZ-7.
