I'm pretty sure the V-1 pulse-jet flying bomb used a rocket to launch and get up to flying speed. I don't recall whether it was a solid fuel rocket like the contemporary American JATO, catalyzed hydrogen peroxide monopropellant. or a liquid rocket with hydrogen peroxide oxidiser. If I had to guess I would say the second.
