1. A method of providing jamming techniques from an electronic warfare (EW) system, the method comprising:

  • updating EW firmware by adding a new jamming technique to the EW firmware and changing parameters of one of the jamming techniques in the EW firmware;

    storing parameter sets for a set of jamming techniques including jamming techniques other than those currently available by use of the EW firmware in a library of the EW system, the library storing a greater number of jamming techniques than a number of jamming sets able to be generated by the EW firmware, wherein the new jamming technique is added free from eliminating other jamming techniques;

    indicating to an Operational Flight Program (OFP) that the EW firmware has been updated;

    generating a jamming technique in the EW firmware using parameters transmitted by the OFP to the firmware, the same OFP being used to trigger generation of jamming techniques prior to and after the updating of the EW firmware; and

    transmitting the jamming technique to provide countermeasures against a radar signal impinging on the EW system.
