Yep, radio-controlled primarily. The Germans were far ahead of everyone in that game and had been working on such weapons since before 1940. Their captured tech was later used in weapons like the Azon bomb (Korea) and the Bullpup missile (of Vietnam fame). We (the U.S. and allies) developed TV guided bombs (tech later became the Navy's Walleye and USAF's GBU-15), radio guided weapons (old B-24s and B-17s packed with explosives and then flown into hard targets like u-boat pens and V1-V2 sites *JFK's oldest brother died on such a mission), and even pigeon guided bombs.
And then you had the special Kamikazes, like the "Cherry Blossom", which was essentially a guided air to surface missile (anti-ship) with a man in it.
If it counts, both the Germans and the British used radar and radio to guide their bombers to their release points. We (the U.S.) later refined the tactic further so we could get in closer and more accurate (close air support with small attack aircraft in Korea and close air support with massive B-52 strikes in Vietnam).
