The United States is boosting the presence of strategic bombers and missiles in Japan and South Korea.
Four B-1-B Lancers, the most powerful bomber in the US arsenal, have on April 15th been deployed to Japan for the first time.
Reports suggest the US may for the first time, also soon directly deploy a squadron of its own F-35s to an American superbase in South Korea. Experts say these moves are meant to send a message to China and Russia, raising fears of military escalation.
I’d there data for how well US systems perform? Do they use them against Russian targets?
If you want data on how NATO stealth/low observable cruise missiles fair against the Russian air defence network during wartime, you can look at Storm Shadow/SCALP-EG (British/French cruise missile) strikes against Russia by Ukraine. There have been a number of successful strikes. Russia intercepts some, but there still have been some notable strikes. It’s not realistic to intercept all. The US has not given JASSMs or LRASMs to Ukraine.
The main problem the Ukrainians have with their cruise missile attacks is not the effectiveness of the missiles themselves, but getting their aircraft in position to launch an attack, due to the superiority of the Russian Air Force vs the Ukrainian Air Force, long range Russian ground based air defences like the S-400 and S-300V4, and the reduced range of the export variant Storm Shadow/SCALP-EG (290km/180mi). Also because Ukrainian Su-24 aircraft can only carry 2 cruise missiles each, the amount of missiles fired in each attack is not that large.
The USA will not have those issues, they have strategic bombers capable of launching dozens of missiles at a time which Ukraine do not, the JASSM or LRASM has a range of 1000km and US escort fighters (F-22 and F-35 stealth fighters with AIM-120s, F-18Es with air launched SM-6s, EA-18G electronic warfare aircraft) will be able to get the bombers within 1000km of frontline targets. That’s why I compared a potential US bomber attack to current Russian bomber attacks on Ukraine, thry are much more alike than Ukrainian attacks on Russia. I don’t think there are many differences between Russian systems and US systems that would effect the outcome that much.
