ABSTRACT:
An improved round for a mortar is shown to include a streamlined, jettisonable nose covering a hemispherical infrared (I.R.) dome incorporated in a gyroscopically stabilized I.R. seeker, deployable wings and a jet control arrangement; during the initial phases of flight the streamlined nose is in place and the deployable wings are deployed so that the aerodynamic characteristics of the round are similar to those of a conventional round, but, in the terminal phase of flight, when the nose is jettisoned the jet control arrangement may be operated in response to commands from the I.R. seeker to direct the round to impact on the top of a selected target.
