Here's a set of RIMPAC 2014 pictures I am putting together. There will be more, and I will have a Flickr album for it too.
The US Navy was going to have the USS Independence participate virtually, but decided to have her go over to Hawaii to actively participate there, while the USS Coronado, LCS-4, actively participates off of San Diego.
The US Navy vessels (including US Coast Guard) are always the largest participant. This year, these vessels will participate (including in a separate operation of RIMPAC 2014 being conducted with other nations off San Diego)

That's 28 vessels. The US will also have well over 100 aircraft involved.
26 vessels from 16 other nations are participating with several dozen aircraft as well.
And which nations have the second largest active participants in terms of vessels?
Why that distinction goes to only two. Both China and Canada will have four vessels participating.
Korea will have three, and several nations will have two vessels participating.
