I’m surprised they seem to think that Tomahawks ain’t vastly outdated and would have any chance against Russian SAMs and their air defense network. The Tomahawk is far too slow and old to get thru S400’s or even S300’s IMO.
Russia has always had a leg up on us when it comes to missiles and rocket engines. They had to, because they knew they could never compete with our USAF. Hence, since the 50’s, they’ve put a ton of effort into their missile programs and that has paid dividends as seen by their hypersonic missiles which we really have no counter for, along with their IADS.
