The comparable figure of radius for the Super Hornet is about 800 miles, compared to 630 miles radius for the F/A-18A-D -- and the gold standard of comparison is the F-14D's CAP radius of 1240 miles (footnote: when armed with AIM-7's vice -54's). The F-14A's is about 1000 miles.
Bottom line, Chinese PLAAF Su-30MKK's now enjoy an advantage over fleet CAP's in both radius and reach.
Bottom line, we're asking Naval and Marine aviators to stand up to people driving better airplanes armed with rangier missiles. The AIM-120 AMRAAM has a range of about 50 miles; its MRAAM competitors carried by the Su-27 "Flanker" family, the R-27/AA-10 "Alamo" and the R-77/AA-12 "Adder" (sometimes called the "AMRAAMski"), have ranges from 42 out to 78 miles depending on the variant, and they're backed up by the aforementioned LRAAM.
I wonder just how accurate the range figures are for US-made A2A missiles. The data never seems to update as new revisions come online. Frankly I think it's like the top speed figures on many US aircraft -- they just give you a nominal figure.
