The U.S. military buildup for a possible attack on or from Iran took another step forward Monday as the USS Abraham Lincoln Carrier Strike Group (CSG) entered the U.S. Central Command region, a U.S. official confirmed to The War Zone Monday morning. Meanwhile, Iran on Monday said it was “prepared to defend itself against any new aggression” while its proxies in Yemen and Iraq have vowed to enter the fight on Tehran’s behalf. The Houthis on Monday released a video suggesting an attack on the Lincoln. More on that later in this story.
Elements of the Lincoln CSG were dispatched to the region from the South China Sea by U.S. President Donald Trump, who has repeatedly threatened to strike Iran over its brutal crackdown on anti-regime protests, resulting in thousands killed. The carrier, along with three Arleigh Burke guided missile destroyers escorting it (and usually a fast attack nuclear submarine), is currently located in the Indian Ocean, a U.S. Navy official confirmed to The War Zone.

The arrival of the Lincoln CSG to the region follows a U.S. Air Force Central (AFCENT) announcement on Sunday that it will be conducting Agile Spartan, “a multi-day readiness exercise to demonstrate the ability to deploy, disperse, and sustain combat airpower across the U.S. Central Command area of responsibility.” AFCENT told us that Agile Spartan is “part of its regular exercise schedule and not in response to current tensions.” However, the optics of the timing are hard to avoid.
All these moves come amid a large surge of offensive and defensive assets to the Middle East. As we have previously reported, at least a dozen additional F-15E Strike Eagle fighters have been deployed to Muwaffaq Salti Air Base in Jordan, along with cargo jets and aerial refueling tankers across the region. In addition, online flight tracking indicates the movement of new air and missile defense systems to the Middle East as well. As we projected, the U.S. is sending additional Patriot and Terminal High Altitude Area Defense (THAAD) systems to the Middle East for increased protection from any Iranian attack, The Wall Street Journal reported.
