2 LACM used by Tu-160, Kh-101 the new big, 2.4 t much fuel range of 2700/5000 km ! warhead 400 kg accuracy ~ 5/10 m and Kh-555 conventionnal variant of Kh-55/AS-15 with CFT 1.5 t, 2000 km, warhead 400 kg accuracy 20 m.
Tu-95H use also Kh-555 later Kh-101.

Does anyone know, why the Kh-555 has these strange offset / staggered canards ?

They are stabilizers, which are fixed in position and provide additional stability in the forward fuselage, in order for the aft control surfaces to have something to "work against"?? That's the best way I can explain it, its like a fixed "fulcrum" to allow the control surfaces to change the direction of the missile.

I believe the Tomahawk has a small deployable wing forward to serve the same function. The KH-555 instead use these fixed forward stabilizers to simplify and economize the design.

Of interest are the verts attached to the top of the main wing at approx. 1/3 span on each side?

But why is one further in front of the other and slightly set above the other one ?

My educated guess would be to load into a rotary launcher, or to stack them in a weapons bay, just as you would layer arrows, in a bow mounted quiver, cock feather up, cock feather down in order to keep the feathers from impinging on one another, while having the shafts closer to one another.

The other possibility is a design/signature feature, ( as with the old Beechcraft Staggerwing), or the horizontally opposed cylinders of a BMW Boxer Motor?? some type of dynamic stability, yes they are odd, but they are efficient.

of greater interest to me are those two vertical stabilizers on top of the wing of the Tu-160??
