The boat was ordered as the first modern S-boat with "Staukeil" (stem wedge) and "Staurudern" (trim rudders) from Fr. Lürssen-Werft at Vegesack. Construction Number 12.120 was commissioned on 07.08.1930 as "UZ (S) 16" [Unterseebootzerstörer (Schnellboot) = Submarine destroyer (fast boat)]. On 31.01.1931 it was renamed "W 1" [Wachboot = guard boat] and got her final designation "S 1" on 16.03.1932. Stem wedge and stem rudders were providing the boat with the so called "Lürssen-Effect", i.e. the boat was with correct trim about 2 knots faster than without the stem rudders and the boat was sailing at a more even keel than without the stem wedge. These features were used by all German S-boats of later build.

The orignally open steering position was changed into an enclosed steering house after testing. The torpedotubes were removeable.

She was decommissioned on 10.12.1936 and sold to Spain in 1937 together with  "S 2" through "S 6". There "S 1" was commissioned as "Bajadoz". Since 1939 she was designated as "LT 15" (Lancha Torpedera). 1940 she was decommissioned.
