Note the wipers, one wiper for each pane.

This image got me wondering. How does the F-22, with
its large, bulbous canopy, deal with the rain?

The same question could, of course, be applied to the
F-35, F-15, etc.

Nope, they do not. They do not need it. The speed does it job and from the
bubble canopy the rain simply flows down.

There's a little more to it than that on most aircraft. A hydrophobic
surface treatment (similar to Rain-X but more persistent) is applied
to the window to (along with bleed air) help with the water-slinging
during taxi and at lower speeds. Seems like it had to be applied
every 100 hours or so, but I forget a lot these days.
