"...the fuel works as a giant heat sink."

It's a big mistake to only prepare for yesterday's enemy. Existing Russian SAMs can already detect and shoot down our best stealth bombers. These systems get cheaper by the year, and are available to practically any buyer looking to keep their airspace clear.

There were experimental 'swivel' jets in the 60s that looked a bit like this. Needless to say, they weren't successful.

I just like that helmet.

Russia is seriously broke. They hate sharing with the Chinese but it's a trade off they have no choice but to cope with.

Too early. Skipping a generation of technology is Hollywood. X-47 is a step closer, but flying a bomb to target is not the same as dog fighting. The programming required for that is practically exponential and will need to be updated often.
