Is german, Henschel Hs130. Its an -E I think, with the HZ-Anlage thing (or whatever it was called). It was a german experimental bird for ultra-high flying tests.
The plane had two DB603s on the wings and a specially modified DB605 mounted into the fuselage.A set of air intakes scooped lots of air,and central engine compressed it to supercharge the DB603s. That plane reached some amazing altitudes for its time (42000 feeet around 41-42).
I dont know why that arrangement wasnt used operationally for bombers, tho. I know that the system was a fuel hog, but other than that it proved workable, AFAIK.
