Agree about the aircraft coming from Poland.
As far as "speeding up F-35 shipments," that will not happen for a number of reasons - first, the pace of production has been contracted and more than likely "the customer," be it the US or a foreign buyer will make progress payments based on that negotiated production rate. Second, vendor made parts and sub-assemblies will have to be accelerated, some of these items like landing gear are long lead time items so that will definitely impact any accelerated timeline. Third consideration, someone will have to come up with a contract modification and money to LMCO to make this happen, LMCO will not make any attempt to bring in additional resources on their own. The last major consideration (there are many more) is once you get everything in place you will need the people to support production, and keep in mind that you re going to have a learning curve once you get everything in place.
