Navy asks Lockheed Martin to set up obsolescence-mitigation program for electronic parts on F-35 combat jets

PATUXENT RIVER NAS, Md. – U.S. Navy combat aircraft professionals are inquiring Lockheed Martin Corp. to established up a software to mitigate obsolescence of digital elements over the lifetime of the nation’s fleet F-35 fight jets.

Officials of the Naval Air Units Command — the invest in agent for all U.S. F-35 plane — announced a $25 million get very last month to the Lockheed Martin Aeronautics phase in Fort Really worth, Texas, to offer diminishing producing source (DMS) management for the F-35. Lockheed Martin is the primary F-35 designer and company.

DMS refers to the obsolescence of digital elements these types of as pc processors, area-programmable gate arrays (FPGAs), electrical power supplies, and databus interface chips. These elements go obsolete significantly extra immediately than weapons programs like the F-35, so the military has to plan for providing integrating modern-day pieces as the obsolete elements that require replacing develop into tough to get hold of.

This purchase phone calls for Lockheed Martin to evaluation and identify genuine and possible DMS issues of elements, elements, materials, assemblies, subassemblies, and software package items, and recommend remedies to mitigate difficulties in assistance of the F-35 plane.

The Lockheed Martin F-35 joint strike fighter has been in development for extra than 27 decades, even though the plane is one of the most recent combat plane in the globe. Now take into account that the average lifetime spans of commercial electronics spare elements are 3 a long time or much less.

The most immediate way of dealing with DMS digital pieces is to make life time purchases — essentially shopping for up every part that manufacturers have on hand ahead of they cease generation totally. Even right after producing life time buys, systems integrators from time to time inevitably need to depend on aftermarket sections makers, areas brokers, or the so-called “gray market place” to preserve spare electronic components on hand.

It can be a time-consuming and expensive process to make sure that obsolescent pieces stay readily available for armed forces weapons platforms like the F-35, which should remain in leading problem for numerous decades.

With no such a source of spare digital areas, techniques integrators like Lockheed Martin would be confronted with redesigning digital subsystems with the latest generations of electronic pieces. As desirable as that seems, it is really even extra pricey and time consuming than keeping obsolescent spare digital parts on hand.

Redesigning a intricate electronic subsystem can take a very long time, and an even longer time to certify for security and efficiency. Most very likely this quarter-billion-dollar financial investment the Navy is making in F-35 spare sections in the lengthy run will conclusion up remaining a superior offer.

On this buy Lockheed Martin will do the do the job in Fort Well worth, Texas, and must be concluded by July 2023. For much more details call Lockheed Martin Aeronautics on the internet at, or Naval Air Programs Command at
