On the 28th of May, Mariusz Blaszczak, Polish Minister of Defense informed via social media, that the ministry sent a Letter of Request (LoR) to the American Defense Security Cooperation Agency (DSCA). The LoR concerns procurement of 32 of multi-role, 5th generation, Lockheed Martin F-35 Lighting II aircraft in the Conventional Take Off and Landing configuration.
The order would be completed as a part of Harpia program, which was reprioritized in November 2018. New aircraft would support the F-16C/D Block 52+ airplanes and replace the obsolete MiG-29s` and Su-22s`. The analytical and conceptual phase of the Harpia program started on 23rd of November 2017.
Letter of Request was sent on 28th of May. Besides the aircraft, Poland is also interested in purchase of logistical and training package. The LoR is a formal start of the Foreign Military Sales procedure. Before anything happens, American Department of State must agree to the export and then the DSCA will provide a quote as a part of FMS procedure.
American response, most likely positive, is expected within next few months. This is when details pertaining to the possible order, plane specification, and maximum value of the contract will become available. The contract value will be then negotiated by Poland.
