The U.S. military unleashed B-2 stealth bombers to target underground bunkers used by Yemen’s Houthi rebels early Thursday, a major escalation in the American response to the rebels’ attacks on Mideast shipping lanes that appeared to be a warning to Iran as well.
While it wasn’t immediately clear how much damage the strikes caused, the attack appeared to be the first use of the B-2 in combat in years and the first time the flying wing targeted sites in Yemen.
In announcing the strikes against the Houthis, who have been attacking ships for months in the Red Sea corridor over the Israel-Hamas warin the Gaza Strip, U.S. Defense Secretary Lloyd Austin made a point to offer a warning likely heard in Tehran as well.
I don’t think that the Houthis have S-400s (and I can’t imagine that Russia has been providing them to anyone in the last couple years, given as how they have a shortage themselves, and it’s probably one of the more-critical shortages that they face).
I can’t find any reference to the Houthis having them online, at any rate.
I think it’s more of a general confidence that there really is no system capable of detecting it. It flew halfway across the world, and radar systems usually have very high ranges. It wouldn’t necessarily need to be the Houthis that have the system.
If you remember, they didn’t let Turkey buy F-35s because they also had S-400s. They didn’t want it to be “public” knowledge how they match up. The US now knows, hence more confident stealth aircraft deployments.
It’s just my theory anyways.
