Not many military jets offered yet; so let me jump in!
The VRS Super-Hornet was recently released. AMAZING bird from what I've seen and heard, and for the moment is an FS9 exclusive!
The Alphasim F-22A Raptor is another amazing bird. Highly maneuverable as far as the sim goes, able to do power loops, high AOA flight, and all the other nifty little tricks that the real bird can do! Excellent VC, looks downright AWESOME, and just fun!
Another bird from Alphasim... The Su-33! The Naval version of the Su-27 and Su-35, the package also comes with Russia's only Aircraft Carrier... the Admiral Kuznetsov. And yes, You can take off from the carrier! And LAND! The bird itself is a bit tricky to handle, but you'll pick it up quickly!
More Alphasim birds...
Their Eurofighter Typhoon is another great one... Fully modeled VC, including the rear cockpit on the two seater models; and excellent flight dynamics. Plus, the entire plane; inside and out; looks real enough to drool on! :P
If you like heavier birds, they also have the C-5A Galaxy and B-1B Lancer. Both have "Simplified" flight dynamics available if you'd like, as they can be quite tricky to land... considering their massive weights! Both are amazingly fun to fly (From tactical landings in a C-5, to high speed, low level "bombing" runs in the B-1B!). Much fun has been had with both birds for me

If you like the B-1B, you can also try out their Tu-160! Very similar... a little faster, and a lot bigger
