WWIII when?

They get used often, as part of training. All 19(there are 21, q have about 1,000 missions a year. They have been used in Iraq, Afghanistan, Libya, and Yemen. They are very outdated in stealth tech and can only safely be used against opponents that lack modern-ish radar.

They are the only plane that can use the GBU-57A bunker buster.

These planes aren't used often. They're strategic bombers and the most expensive of America's bombers too. Both in per flight hour cost and absolute cost

The B2 spirit is primarily made for the nuclear deterrence and warfare role. They are designed to penetrate air defense systems by being stealthy, A concept that was proved by the f-117 Nighthawk.

But since they have a heavy payload they're also used to drop conventional bombs occasionally. When you have to service a large amount of targets or use really big bombs, A strategic bomber is the go-to solution. They used B2 in this case for what my guess is these reasons

• stealthy means they can get past radar systems and they can shrink any warning time
• The B2 is the only plane rated to carry the gbu-57 bunker busting bomb. The facilities they were trying to destroy were fortified, so most other bombs wouldn't work.

They're the only planes that can carry the biggest bunker buster massive ordinance penetrator.

The whole point of stealth planes is not to have publicity…

The porcine Christian nationalist ones will

I guess its because of the shape of the airplane it looks like there are pixels missing. Like you sometimes see in videogames with glitches or when a TV has dead pixels.
