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.

The B-52 uses bleed air to prevent ice build up on the inlets, inlet
guide
vanes, EPR inlet probes and, on the H model, the cowling. I'm not sure
if
you
can see anything visably though, most of it is internal.

The Argus (ASW aircraft slightly bigger than a C-130) was used in
severe icing conditions (low level over the North Atlantic) and
was well equipped with anti-icing and deicing equipment. They had
huge gas fired heaters (600 BTU each) one for each wing and one
for the tail, plus a 300 BTU one for cabin heating. They also had
numerous anti-ice mats for cowlings and other air-scoops plus
electrical prop deicers and 'Nesa windscreens'. I've flown
through some horrendous icing conditions believe me. The
replacement aircraft for the Argus (P-3 Aurora/Orion) has great
wing anti-icers utilizing engine bleed air, very effective
indeed.

The engines on the P3 also Anti-ice "themselves". One switch per engine
opens two solenoid valves, one of which directs air to the air scoop, the
other causes a pressure imbalance in two valves fitted at the nine and three
o clock positions on the air inlet housing. These two valves anti-ice the
air inlet housing, IGV's CIP and CIT probes and the torque meter shroud. The
solenoids are energised closed so are fail safe. Two thermal switches wired
in series, are fitted to the air scoop and torque meter lines, they
illuminate an anti-ice light in the flight station within 60 -90 seconds of
selection when the temperature of the pipe reaches 93 Degs C. A TIT increase
of approxamately 22 Degs C and a SHP drop of Approx. 9% will also be noted.
The props are electrically de-iced with the first 22 " of the spinner
anti -iced. :-)
