#57 - Su-33 Flanker D
Kh-61 Yakhont (Air Launched Version of the P-800)
Kh-41 Moskit (Air Launched version of the P-270)
Air launched version of Oniks/Yakhont/Brahmos not ready to flight test and required strengthen central pylons on plane
So I doubt that Su-33 can use it even if can take of with this missile
About Kh-41 Moskit , yes this programm exist in early 90s, but not for Su-33, this missiles intended to be used
with Su-33KUB (two seater, new strengthen airframe,bigger wings, new PESA radar Zhuk-27 , wide range of A2G load, programm further evolved into Su-34)



Also main problem is Su-33 fire control system limited to A2A missiles, Su-33 even cant use more simple Kh-31P
and you want it to use more complex Kh-41 [:)]
In 2016 will start upgrade programm for Su-33 (something like Su-27SM upgrade for Su-27) but I dont think Su-33 will receive Air Launched Oniks or Kh-41, more like L-150 and ability to use Kh-31P/A (since this is Navy they may want A version), standard package of Kh-29,Kh-25(or even Kh-38) and ability to use new A2A missiles
