Testing of the P.108A was satisfactory, achieving a maximum speed of around 440 km/h (270 mph) due to aerodynamic redesigning. It flew to Furbara on 19 March, and later to Pisa on 16 April, where it carried out a series of firing trials at altitudes between 1,500 and 4,500 m (4,900 and 14,800 ft) to collect the ballistic data that was required to allow the computing gunsight to be produced. After totalling 24 hr, 40 min of flight and weapons trials, it returned to Albenga. It was presented as the new official attack machine at Furbara on 22 May, and it was planned to build five further P.108As, as well as converting between five or possibly all P.108s available. But on 29 June, it was decided to produce no more than five aircraft, and in July, the order was further limited to two, and eventually cancelled. On 6 and 8 September, the lone P.108A made other weapons tests over the sea, finally equipped with the S.Giorgio calibration/aiming system. German forces took control of the P.108A and painted it in their insignia, but it was damaged soon afterwards by Allied bombing. Repaired by 7 April 1944, it finally flew to Rechlin where it was probably destroyed in one of the many Allied bombing raids.
