Israel Developing Python 6 Based on Stunner SAM/ATBM

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 (paid subscription required):

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.

Personally, I'm a little bit dubious that the missile will go completely without a warhead, the PAC-3 Patriot, for example is hit to kill, but contains a "lethality enhancer" (basically a tiny warhead to scatter shrapnel in the path of the target.

That being said, using a dual mode seeker (you can see how the IR seeker is offset so as to allow a radar to be placed behind it) the missile's accuracy should be pretty high.

They also expect this to be the last AAM they develop.

Yosi Druker, director of Rafael's Air-to-Air and Air Defense Directorate, suggests that they will be superseded by new technologies, because "the next generation of interceptors will employ other kill mechanisms, not necessarily a missile, to defeat airborne targets," which I take to be a reference to directed energy weapons.

I'm dubious of this, but I've been wrong more often than not when I have been dubious about a technological development.
