The Barracuda (which I assume is what you're referencing to) is not nearly as performant as the Tomahawk. The largest Barracuda has a range of ~500nm, and carries a 100lb warhead, and is air launched (there claims to be a ground launched version, but it might result in reduced range). The Tomahawk has a range of like ~900nm carries like a 700lb warhead and can be ship/land launched (so it needs extra booster).

The Barracuda would be really really useful a lot (probably most) of targets and missions, but we can't pretend like there's no tradeoff in performance and additional limitations. Very roughly a Tomahawk has twice the range, and 7 times the payload.

Will they work reliably if they're being fired at someone Thiel likes?
