Considering Syria’s advanced anti-aircraft capabilities (thanks Russia!) I’d guess the B-2 stealth bomber is the most likely choice in the initial campaign.

WASHINGTON (WSJ) —A key Senate panel on Wednesday backed President Barack Obama’s request to strike Syria, while the Pentagon prepared to employ greater firepower to reach a shifting array of military targets.

The revised options under development, which reflect Pentagon concerns that Syrian President Bashar al-Assad has dispersed his military equipment, include the use of Air Force bombers to supplement the four Navy destroyers armed with missiles that are deployed in the eastern Mediterranean. Initially, Pentagon planners said they didn’t intend to use aircraft in the proposed strikes.

The Pentagon shift came amid an accelerating tempo toward U.S. military action in response to the Assad regime’s alleged use of chemical weapons on a large scale Aug. 21, an attack U.S. officials say killed more than 1,400 people, including hundreds of children.

The Navy destroyers in the Mediterranean carry about 40 Tomahawks each. Air Force bombers could carry dozens more munitions, potentially allowing the U.S. to carry out follow-on strikes if the first wave doesn’t destroy the targets.

Among options available are B-52 bombers, which can carry cruise missiles; low-flying B1s that are based in Qatar and carry long-range, air-to-surface missiles; and B-2 stealth bombers, which are based in Missouri and carry heavy guided bombs.

Like Mr. Assad, the Pentagon is trying to take advantage of the extra time before a U.S. strike. A senior U.S. official said that Mr. Assad’s movement of equipment has helped the Pentagon identify additional targets at previously unknown locations.

“Could the delay remove a target? Yes. But it is also creating targets. We are finding things we didn’t know existed,” said the senior official, who declined to specify the types of targets.
