You mean a Nuclear Missile.
It wouldn't make much sense tho, cus Hitler thought of nuclear technology as Jewish technology.

If you're up to it, i think you could make a pretty popular mod out of ww2+ helicopter tech tree and a more expanded jet tech tree. i.e. bell prewar experiments for america, german fa 223 dragon helicopter, and add jet experiments like the prewar german tests. you could also add expanded rocket science like v1, v2, u-boats with V1s (and alternatives for other countries) and experimental bombers like the 'amerika bomber'. just a mod to add late war experimental stuff that never quite made it irl.
