A example of this type, with RNAS registration N6164, landed on March 1, 1917 near Cadzand.
It entered service with the LVA registration LA41.
On May 23, 1917 was compared with the Spijker V.1. The result was such that the type was considered to be built under license by Trompenburg, but the director H. Wijnmalen, preferred the Nieuport XI.
In 1918, a new registration system was achieved and the Pup received the new serial S212.
