Why there is a duck-like shape in this Tomahawk missile's nose? I see this shape in most Tomahawk images; however, not every Tomahawk's nose is shaped like this. If it is an aerodynamic feature, what is its common name?

the shape can be clearly seen in this image

I developed the shape for Convair back in the late 90's. It was called a chined nose and Carlo is right, there were no aero considerations for this shape. It was purely RCS.

While this really should be a comment on Carlo's answer, I'm giving you an up vote so you can start earning enough rep to be able to make comments where appropriate.

Hope you stick around - that's the kind of background and knowledge that's absolutely invaluable 'round these parts! $\endgroup$ – FreeMan Sep 30 at 18:10

It’s a feature on the latest variants of the Tomahawk to reduce its frontal radar cross section. It has no aerodynamic role for the weapon.

  • $\begingroup$ Hello! The last sentence is a bit irrational. A geometric shape definitely has an aerodynamic role, be it a small contribution towards stability/performance or a large one. $\endgroup$ – Gürkan Çetin May 26 '18 at 8:05

    $\begingroup$ I think what is meant is that any beneficial or detrimental contribution to the missile‘s aerodynamics and flight mechanics was tolerated in order to achieve the radar cross section objective. $\endgroup$ – Cpt Reynolds May 26 '18 at 11:53

    $\begingroup$ Meaning that shaping is not necessary for aerodynamic reasons and is added for low observability enhancement only. $\endgroup$ – Carlo Felicione May 26 '18 at 16:34
