SLiM Chance...

Interesting, yet naive.  This approach would work for major components like the processors E2V provides, but the world of Mil / Aero Engineering is so comples and uses such a high mix of components, both Mil-Spec and COTS, that having this type of agreement in place for every component, even every manufacturer, is impossible.  And there are a number of manufacturers who wouldn't even hear of it.  They are driven by next gen technology and profit.  Then there are a lot of fabless companies that would go undeer if they had to manage a program like this long-term.  I think it is idealistic, but simplistic.

SLim is definitely an answer to the woes of many military and avionics OEM companies struggling to get the required supply of older components. But who is going to actively start doing this. Is it the OEM's that should be formed as an organization to encourage this practice or the component suppliers who will be also benefited by this Slim to have constant sales for years? This will also result in making the OEM's stick to the working designs for very long times with out regularly changing designs. In addition to this it is also important for the engineers to design products by getting in line with component supplier road maps to avoid the faster obsolescence.

Portability can be built in

The approach of wafer banking to ensure the supply of the outdated ICs is a good insurance  against the unavailability of old components. Here I would suggest another approach , that of portability. Most of the Semiconductor companies publish their product maps for the next 3 - 5 years and have planned phasing out of some component series while introducing  new generation components.  While designing the Electronics for military and aviation products if these product maps are taken into account and similar migration plans are made right at the time of initial design of the product then the problem of old parts becoming non-available can be solved by planned replacement of compatible newer components into the existing designs and thus keeping the product up-to-date.

Thanks for the post Joseph

definitely there should be a sequenced life cycle in the field of semiconductor for defence because the requirementa may shoot up suddenly its very uncertain. the dubbed concept of SLim is really good especially th e waffer manufacturing should improve and speed up their process.
