The US Navy is hoping to increase the range of theair/air missile by some 60% over current variants. The Navy seek this enhanced capability particularly for the Lockheed Martin Joint Strike Fighter, the Naval Air Systems Command ( ) says. The new weapon is scheduled to become operational in 2022.
According to, the current Block II AIM-9X already overlaps some of the range capability of the more powerful AIM-120D AMRAAM, and this overlap is expected to increase with the future Block III, providing the F-35 pilot the flexibility to employ both radar guided or passive homing missiles in Beyond Visual Rang (BVR) engagments, NAVAIR says.
“The need for that added flexibility arises from the proliferation of advanced digital radio frequency memory (DRFM) jammers that many potential adversaries are adding to their fighter fleets.” Dave Majumdar, of FlightGlobal commented. “DRFM jammers have the potential to blind the AMRAAM’s onboard radar, which makes the AIM-9X’s passive imaging infra-red guidance system a useful alternative means to defeat those threats. While a completely new missile would have been ideal, the Pentagon is faced with era of declining budgets and has to take into account the price tag of any new weapon.”
While the Pentagon needs the newto be a supplemental BVR weapon for situations where friendly fighters are faced with electronic attacks that degrade with radar-guided weapons, it will not compromise on the AIM-9X’s close in performance. “The requirement and design call for the same WVR [within visual range]/HOBS [high off-boresight] capabilities as those found in the AIM-9X Block II,” NAVAIR says.
The Block III is currently scheduled to enter into its engineering and manufacturing development phase in 2016, NAVAIR says. Subsequently, it will go into developmental testing in 2018 with operational tests starting in 2020. If all goes well, an initial operational capability date is expected in 2022. “The Block III development schedule follows the increased number of Joint Strike Fighter aircraft entering service,” NAVAIR says.
The AIM-9X features a fifth generation staring focal plane array IR seeker with a high off-boresight capability. AIM-9X is an advanced IR missile. It is mounted on a highly maneuverable (thrust vectored) airframe, along with digital guidance and IR signal processing that results in enhanced acquisition ranges, greatly improved infrared counter-countermeasures capability, and extremely high off-boresight engagement zones for unprecedented first shot/first kill air-to-air performance.
