About this page

A stock number is tied to the P-8 when the federal catalog's item characteristics name it as the end item; spellings and series letters (KC-46A, F/A-22) are folded together. Demand and prices come from DLA DIBBS, vendors from the award record, risk from the obsolescence watch. Same page for every reader. Data, not advice.
