U-103 was launched on 9 June 1917 and commissioned 15 July 1917
U Boat 103 was a Type U-57 submarine powered by a 2400 hp power plant and could reach a speed of 16.8 knots on the surface and 9.1 knots when submerged with
a surface range of 11,220 miles and 56 miles when submerged.
Her armament included 16 torpedoes with two stern and two bow tubes. She carried a 105mm and a 88mm deck gun with 22o rounds of ammunition,
and a crew of 39 crew.
She was commanded by KptLt. Claus Rücker and participated in 5 operations sinking 8 vessels of 22,249 tons.
KptLt. Claus Rücker also commanded U-34 from Oct 1914 - 11 Dec 1916,
and sunk 80 vessels at 174,655 tons and damaged 3 vessels at 9,951 tons.
On 12 May 1918, U-103 engaged the troop transport, RMS 'Olympic' sailing to France carrying US troops. While preparing to launch her torpedoes, the U-103 crew encountered difficulty in flooding the two stern tubes and was sighted on the surface by the RMS 'Olympic' who opened fire and prepared to ram her.
The U-103 dived and attempted to run parallel as to avoid collision however, the U-103, unable to dive fast enough was rammed aft of the coning tower by the RMS 'Olympic's port propeller depressurizing the U-103's hull.
In an desperate attempt, the U-103 blew the ballast tanks in an attempt to abandon ship which quickly sank at a position approximately. Thirty five submariners were able to escape to be rescued later that day by the USS 'Davis'.
