I have yet to come across any primary source information about Focke-Wulf designation P.95, but from what secondary sources claim, both the P.195 and P.95 were part of Focke-Wulf's "Grosstransporter" (Large Transporter) project from August 1942.
For this project Focke Wulf proposed 2 large transport aircraft - a 6-engined and an 8-engined variant. Most sources nowadays list both of these projects as the Focke Wulf P.195, however some sources designate them P.195 and P.95 respectively.
