Navy forced to invest quarter-billion dollars to safeguard electronic spare parts for F-35 jet
PATUXENT RIVER NAS, Md. 1 Aug. The Lockheed Martin F-35 joint strike fighter has been in development for more than 16 years, even though the plane is one of the newest combat aircraft in the world. Now consider that the average life spans of commercial electronics spare parts are three years or less.
It stands to reason that at least some of the F-35 many sophisticated subsystems might have a difficult time locating spare parts, since many of these parts have become obsolete and have gone out of production since the first F-35 prototype flew in 2000.
Not only is it difficult to keep a steady supply of spare electronic parts in stock for the F-35 and other high-technology military systems; it's expensive, too.
That's why the U.S. Navy -- contract agent for F-35 procurements for the U.S. Air Force, Marine Corps, and Navy had to earmark nearly a quarter of a billion dollars this month to help safeguard the electronic parts supply line for the F-35.
Officials of the Naval Air Systems Command at Patuxent River Naval Air Station, Md., announced a $241.8 million contract on Tuesday to the Lockheed Martin Corp. Aeronautics segment in Fort Wort, Texas -- builder of the F-35 -- for diminishing manufacturing sources (DMS) electronic components.
Diminishing manufacturing sources refers to obsolescent electronic parts that the parts manufacturers have ceased producing, or that are nearing the ends of their manufacturing cycles.
The most direct way of dealing with DMS electronic parts is to make lifetime buys -- essentially buying up every part that the parts manufacturers have on hand before stopping production. Even after making lifetime buys, systems integrators sometimes must rely on aftermarket parts manufacturers, parts brokers, or the so-called "gray market" to keep spare electronic parts on hand.
It can be an time-consuming and expensive task to ensure that obsolescent parts remain available for military weapons platforms like the F-35 that must remain in top condition for many decades.
Without such a supply of spare electronic parts, systems integrators like Lockheed Martin would be faced with redesigning electronic subsystems with the latest generations of electronic parts. As attractive as that sounds, it's even more expensive and time consuming that keeping obsolescent spare electronic parts on hand.
Redesigned subsystems take a long time to perfect, and an even longer time to certify for safety and performance. Most likely this quarter-billion-dollar investment the Navy is making in F-35 spare parts will end up being a good deal.
On this contract to make sure spare electronic parts are available for the F-35, Lockheed Martin will do the work in Burlington, Vt., and Fort Worth, Texas, and should be finished by December 2018.
