Lets get some photos all up in here.
Sukhoi-22 fighter jet of the Syrian air force. These were reduced to rubble in the attack, as it was this air force that dropped the chemical weapons.
Russia's Navy is extremely outdated, though the frigate seen here is one of Russia's newest and most advanced ships. They have sent the Admiral Grigorovich frigate from it's base in the Black Sea to Syria, to have a "presence" near the two US Destroyers.
The US Navy has two older destroyers; the USS Ross, and USS Porter, in Syria. These two ships, while older then the Russian frigate, are still more advanced and more capable in every way possible.
The Syrian Navy is not ver strong and made up of old Chinese and Russian ships. They are no match for anything the Russians or American's have in the waters. A single US destroyer could wipe our a major chunk of the Syrian Navy... so don't expect them to get involved.
