How do cruise missiles stay aloft? How do cruise missiles fly? Where does the lift come from? On pictures you can see that they have wings what are tiny compared to the body / payload. Do they generate enough lift? Or is the propulsion, other than in most aircrafts, not just used to overcome drag but also to generate lift, i.e. the thrust force is angled down?
Many cruise missiles have wings of some sort, although these can be very small like on the P-700 (barely larger than their control surfaces) or foldable in such a way that makes them not obvious when the missile is in a stowed configuration, like on the Tomahawk or Kh-55.

Additionally, the narrow body of the missile provides lift. Though it is much less effective at it than a wing would be, this is a design trade-off that can be worth it in some scenarios. For supersonic cruise missiles the narrow-body lift is usually enough and the lack of wings is a plus, as they would generate a disproportionate amount of drag at $M_{\infty} \geq 1.0$. 

One of the main traits of slender wings (and bodies) is that their effect on the surrounding airflow grows with speed at a much  slower rate than that of a high-aspect-ratio wings, making them suitable for high speed applications.
