"smoke on the bomber / and fire in the sky " LMAO

I did not realise that the early turbojet B-52 also used water injection? Was that to increase thrust?

Yes. Cooler air into the turbines which allows more fuel to be burned, more mass flow from the fuel and the water. It's an old Jet trick, works well but causes incomplete combustion = lots of smoke.

The J75 in the F-105 had it too.

As well as a number of other aircraft with engines designed in the late 1940s - early 1950s.

Just a quick glance finds:

J33 (RF-80/F-80, F9F, F-94)
J42 (F9F)
J47 (B-45A/C & B-47E)
J48 (F9F)

Even the Pegasus engine in Harriers used water injection.
