Not really. DoD can decide to sole source the contract if it deems that sole source if it deems that there are no competent competitors, or that the competitors may pose procurement risks, like being foreign source would.
Here's the catch...Obama ran on a campaign against "No-Bid" or "Sole-Source" Contracts ala Halliburton...Looks like the Pentagon needs a second bid as not to upset the One...Politics has been in play in the KC-X process since day one. I am thinking this is upsetting a few Acquisition wonks because Northrop Grumman-EADS isn't playing along.
I've been watching this process going on for three weeks. This report could of been written three weeks ago and it will still be rehashed over and over again til May 10th, when the contract will be awarded.
