Raytheon redesigns AMRAAM to extend missile's lifetime

Aircraft missile experts at the Raytheon Co. are continuing a project to design a new guidance section for the U.S. Air Force and Navy AIM-120 Advanced Medium Range Air to Air Missile (AMRAAM) in an effort to extend the missile's lifetime well into the 2020s.

EGLIN AIR FORCE BASE, Fla. - Aircraft missile experts at the Raytheon Co. are continuing a project to design a new guidance section for the U.S. Air Force and Navy AIM-120 Advanced Medium Range Air to Air Missile (AMRAAM) in an effort to extend the missile's lifetime well into the 2020s.

Officials of the U.S. Air Force Life Cycle Management Center at Eglin Air Force Base, Fla., announced a $64.6 million contract option to the Raytheon Missile Systems segment in Tucson, Ariz., for phase 4b Form, Fit, Function Refresh (F3R) of the AMRAAM guidance section.

The Air Force and Raytheon are redesigning the radar guidance section of the AMRAAM missile to extend the weapons' lifetime into the 2020s.

AMRAAM is an active radar-guided intercept missile with inherent electronic protection capabilities for air-to-air applications against massed penetration aircraft. AMRAAM has been in service since 1991.

The Air Force's AMRAAM F3R project is a comprehensive effort to mitigate the effects of parts obsolescence and diminishing manufacturing sources in the missile's guidance section to enable AMRAAM production beyond lot 31.

Raytheon won a $573 million order in March 2016 for AMRAAM lot 30 production. Each AMRAAM lot roughly consists of 400 to 500 missiles.

Mitigating the effects of obsolescence and diminishing manufacturing sources can involve the substantial redesign of subsystems by replacing electronic chips and other components that the original manufacturers no longer can produce.

In 2015 Raytheon experienced technical difficulties with the AMRAAM F3R application-specific integrated circuit (ASIC) design, hardware integration, and guidance section performance demonstration, which delayed the program's critical design review (CDR) for a year.

The Air Force awarded Raytheon an $8.6 million contract modification last December provide additional ASIC work as part of the AMRAAM F3R phase 4a project, which is scheduled to wrap-up this June. Separately, Raytheon won a $104.6 million contract in May 2016 for AMRAAM F3R work on the missile's guidance section.

Last January, Raytheon officials announced a project to develop a new signal processor under the F3R project to help ensure AMRAAM production well into the 2020s. Air Force officials plan to cut F3R technology into the latter part of AMRAAM lot 31 production in 2019 or 2020.

Raytheon will do the work in Tucson, Ariz., and should be finished by April 2018.
