The S.V.A.4 was the first reconnaissance fighter development
of the S.V.A. to be built in substantial quantities.
It did not demand an escort in performing reconnaissance
missions as it could accept combat with
fighters on reasonably equal terms, and break off combat
at will by utilising its high speed. It was powered by a 205hp SPA 6A six-cylinder water-cooled engine, and
normally carried two synchronised 7.7mm Vickers
guns, although the starboard gun was sometimes removed
when a reconnaissance camera was carried.
The S.V.A.4 entered service with the Aviazione Militare
early in 1918.

The first photograph inserted in the section "Ansaldo S.V.A. 5 Primo", shows (in its original) the words "Ansaldo S.V.A. 5"; this one may be that of a S.V.A. 4, because of the difference in the wheels; but the two aircrafts where virtually identical.
So which is the S.V.A.4 the one in the photograph here, or the one in the photograph on the S.V.A.5 page?
Do you have any comments about this aircraft ?
