The aircraft never passed the preliminary stages.

The Re.2004 had identical fuselage, wings and other components to the Re.2005.

The Re.2004 was powered by an air-cooled Isotta Fraschini Zeta RC 24/60 engine, with 24 cylinders arranged in an X-pattern, producing 1,250 hp (932 kW).

In 1942, a prototype was built, and ten models were ordered; the order was later cancelled due to unresolved engine overheating problems.
