Phased arrays are everywhere. An incredibly common example are many cellular base station antennas. They are fancy but nothing particularly special these days. Active phased arrays, e.g. steerable with either analog phase / delay shifters or with digital front ends are less common but still much more common than the BAE Systems phased arrays in F35's.

They are used for satellite based internet in commercial aircraft also.

Isn't MIMO beam forming that modern wifi base stations use basically a phased array?

I guess the Starlink dish's ~1200 antennas is way way closer to a fighter jet radar than it is to a six antenna Netlink wifi base station...

There are speaker companies that sell phased array loudspeakers for tuning the sound in e.g. a specific corner of a concert hall, where you can't just put extra speakers anywhere you want.
