We have an A-4 and a B-52 on the airport here. Neither seems to have
an anti-ice system as far as I can see (of course the B-52's wing is rather
above my head, and currently covered in snow).

Do Air Force/Navy planes have de-ice equipment? What happens
when the radar dome gets coated in ice while flying through cold clouds?

IIRC the A-4 had engine anti-ice and heated windscreen and pitot tube. No wing
anti-ice. Don't know about the B-52.

Engine anti-ice is necessary in more environmental conditions than is wing
anti-ice. WAI installations are also comparatively heavy and power-hungry.

FWIW, I turned on the WAI in the 747 for the second time in 5 years just the
other day -- more out of curiosity than need; we use nacelle anti-ice routinely.
We were picking up a bit on the descent into ANC, and wanted to see if it made
any difference. Found that the ice on the outboard leading edges melted
first...
