The 1975 technothriller (before the genre was said to exist!) Clash of Titans had a US nuclear-powered rigid airship carrying Harriers and helicopters up against a Soviet carrier with developed versions of the original Yak-36. Ostensibly, both were deployed to rescue an airliner that crashed on a Pacific island but, in truth, both were trying to recover a Soviet defector who was on that flight. Note, this is not the same as the novelization of the movie with Ursula Andress and her boytoy at the time; that was Clash of The Titans.
The airship had two nuclear-powered turbofans using heat exchangers and one turbine-driven turbo-prop large and slow enough to use helicopter rotors as the basis of the propeller blades. This was based on a concept put forward in a 1973 AIAA technical paper.
