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?
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.

In the meantime, please take the tour and read through the help center so you can get the most out of the site. Hope you stick around - that's the kind of background and knowledge that's absolutely invaluable 'round these parts! $\endgroup$– FreeManSep 30, 2019 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. $\endgroup$ May 26, 2018 at 8:05
5$\begingroup$ 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. $\endgroup$ May 26, 2018 at 11:53
