The Israeli defense company Rafael is working to
develop a successor to the Python 5 and the Derby based on their Stunner surface to air missile (

Rafael, Israel's leading missile development center, continues to work quietly on an air-to-air derivative of the Stunner interceptor—to be designated Python 6, or the Future Advanced Air-to-Air Missile (FAAM).
The Stunner is a surface-to-air weapon being developed in partnership with Raytheon for Israel's David's Sling air and missile defense system. The Python 6 has been chronicled for almost a decade.
Although the Israeli air force (IAF) still has not officially endorsed an air-to-air version, sources at Rafael say consultations over the features of such a missile have been underway since the final stages of development of the Python 5, currently in production.
The IAF could avoid committing its own funding to FAAM development, hoping that Rafael can first strike a deal with a U.S. partner to obtain the next-generation air-to-air missile. But according to Chairman Ilan Biran, Rafael is in the meantime using its R&D budget, estimated at $125 million, to fund the project.

The Stunner was designed as a “platform-agnostic” missile that can be adapted for air and ground launch, from rail or ejector racks, in conventional or internal carriage configurations. The Mach 5.5, long-range missile is equipped with a dual electro-optic/radio-frequency seeker and an advanced multistage rocket motor. Designed as a hit-to-kill anti-missile weapon , Stunner has no warhead and instead can carry a more powerful rocket motor capable of ranges beyond any air-to-air missile available today.
Druker says the FAAM will likely cost significantly less than today's AIM-120 , Derby or Meteor, but more than the current short-range missiles. Although the FAAM and Stunner do not share a common configuration, Rafael expects that the overall life-cycle cost offered by the Stunner will be much lower than any other missile combination.
