From June 13. 1942 till February 19.1945, 282 experimental flight tests realized at Peenemuende. 175 rockets were fired from P-7, 46 from P-10 and from Oie 28 rockets were fired for maximum vertical heigth. 117 rockets were made in Mittelwerk, others at Peenemuende.
Next figures are based on book of Willy Ley: Rockets, Missiles and Space Travel.

Numbers of rockets are their production numbers. Rockets 1 to 6 weighed about 1 ton more than later A-4. No.8 was used for crew training; nos. 14,15,17 were stored in the open for more than a year with tarpaulin covers only to test for storability; they were fired after 1943. Nos. 27,32,37 and 39 had various experimental equipment for development purpose.
No.1 was used as a mock-up (Ley) but first prototype exploded during static firing test.
First rockets (during 1942) had rather complicated "chess" camouflage with 9 B&W chess fields in tail section and white horizontal band on black field in space between two others vanes. From the opposite side of view has tail section inverse color scheme.
Experiments in Blizna (Poland) started on the November 11. 1943 and came to end at the end of July 1944. 139 rockets were fired in sum. Next figures are from book of M. Wojewódzki: Akce V-1 a V-2.

Thenceforth between 15.-17.4 1944 two rockets fell near Stalowa Wola, 21.4.1944 two near Kozienic. From 20.4 till 7.5 in area of Platerów, Sarnaki and especially around Meźienin-Ogroniki (Losice county) explosions of 19 rockets espied. During July lot of rockets were fired in direction of Wlodawa and Brześć. They fell in Rejowec area. But the main aim point was Sarnaki village. From April till May about 60 rockets were fired.
