Radar, the BARS is probably still better as the F-15K does not have an AESA.
Payload, the Eagle is getter,
Pilot interface is probably similar, both have helment cueing systems and ergonomics is similar on both, although US planes are know to have better ergonomics. Weapons capability is in the favor of the Eagle which has a huge variety of weapons available to it. JDAM, JSOW, SLAM-ER, and others.

Without Russia, US would dominate, even without carriers, just flood the area with SSNs. But with Russia, and if their stuff still works, then the large Russian submarine force would cause a lot of problems.

Battleship: Yamato or Iowa, but I pick Iowa cause it could kill the Yamato 🙂

Carrier: Gotta love the behemoth Nimitz all the way

Cruiser: Hmmm. since there are only two choices, I pick Kirov it is definitely a looker. The other choice on the other hand…cough…Ticonderoga…cough.. is rather ugly

Destroyer: Gotta go with the Arleigh Burkes, the raked sail is beautiful

Frigate: nod goes to the Dutch and the LCF

Smaller vessel: Visby for now, but I’m rooting for the General Dynamics version of the LCS

Submarines: Seawolf class, the sail is so good looking.

That’s one of the reason’s why the old Tico are retiring, that and the fact that they don’t have VLS, but the new SPY-1C and SPY-1D radars are still some of the world’s best radars. The AEGIS is also the only battle tested, naval mounted, phased array. Since everyone thinks that the Smart-L is so great, you would have to include the SPY-3 AEGIS in there as well because it has been built and tested, just not deployed on a vessel yet.

I am pretty sure some of the Russian SSM’s could knock out a battleship. One of them, carried by the TU-22M Backfire, has a 1000kg warhead and flies at Mach 3+.

What was the secondary armament for the Yamatos? 20×5″ Mk 38s for the Iowas, right?

That’s why they put so much equipment and fancy toys into the planes. For A2G, the pilot really doesn’t have to think anymore. Its more like fly and press the red button because you don’t have to aim A2G ordinance anymore. It is just release it in the weapon’s envelope and it will hit. This is why the USAF is adding A2G capability to the F-15C. It is not hard to train fighter jocks to do ground pounding anymore.
