A guided missile having a longitudinally extending airframe with a tip, a seeker head arranged in the tip and a window located in front of the seeker head for closing the airframe at the tip so as to protect the seeker head. A jettisonable protective cap consisting of at least two separable parts is attached to the airframe in front of the window for protection of the window.

We claim: 1. A guided missile having an airframe, said airframe defining a longitudinal axis, and a jettisonable protective cap being attached to a leading end of said airframe for protection of operative components arranged in said airframe, wherein said protective cap is longitudinally divided into at least two parts which, together, extend circumferentially through an angle of 360째 about said longitudinal axis, each said part extending through an angle of not more than 180째, said at least two parts being interconnectable by connecting means, means for releasing said connecting means; said two parts together and said airframe defining a form-fitting interlocking structure along the airframe-side edge of said protective cap means only upon said two parts being in an interconnected condition, said protective cap having an opening located substantially on said longitudinal axis, said opening facilitating a dynamic pressure to be built up within said protective cap for a sideways detachment from said guided missile coupled by a release of said form-fitting interlocking structure responsive to the build up of said dynamic pressure during flight of said guided missile. 2. A guided missile as claimed in claim 1, wherein said protecting cap comprises a conical cap divided along at least two cone generatrices. 3. A guided missile as claimed in claim 1, wherein said releasing means comprise pyrotechnic releasing means. 4. A guided missile as claimed in claim 1, comprising jettisonable closure means attached to said protective cap for closing said opening, and closure member releasing means for releasing said closure means. 5. A guided missile as claimed in claim 4, wherein said protective cap is frusto-conical comprising at least two circumferentially extending parts each having a front edge and a rear edge, said rear edge adjoining the airframe front edge, and said jettisonable closure means comprise means for engaging said front edge and forming a part of said connecting means, whereby, when said closure means is jettisoned by said closure member releasing means, said dynamic pressure causes said at least two circumferentially extending parts to part sidewise, thereby facilitating release of said form-fitting interlocking structure. 6. A guided missile as claimed in claim 4, wherein said closure member releasing means comprise pyrotechnic releasing means.
