Stents, I can't answer in PM. When revenue starts being generated is tough to say without actually seeing the contract and performance schedule. Navy extended the current contractor for a year, usually accomplished as a risk reduction during transition or to cover down for a potential protest/ recompete...most likely the former. If I was the program manager I'd be thinking 3 to 6 months to allow for stand up, air worthiness, etc and then full performance starting after. IMO though, the contract will enable billing for ALL approved activities associated on a monthly basis depending on invoices submitted and approved through DCMA (defense contract management agency). Hope that helps.
