In the 1950s the USA had programs to create Nuclear power units to power Bombers and recognizance planes.

As we speak Russian scientists are dying while testing prototypes trying to create a nuclear powered/nuclear bomb tipped cruise missile that could cruise for weeks in the Southern Hemisphere of the Earth before a final “Southern Surprise” attack on the USA or Europe.

A plane like the Stellantis Midnight would be far more versatile if it had a small nuclear power electric generator unit for cruise and a lithium battery for boosting takeoff and climb.

But fission nuclear is politically incorrect as fossil fuels.
