The AIR-2A (Genie) was an unguided rocket with a nuclear warhead carried on F106s and F101s in the 70s. It was point and shoot with an internal timer that exploded after a fixed delay that was determined by the launch aircraft's avionics. The presumption was that the Russians would be flying in big formations (think WWII) so one AIR-2A would take down dozens of incoming bombers. The ground launched BOMARC missile with about 400 mile range and 10kt warhead operated on the same principal.
