Enoch Thulin was Sweden's first true aircraft manufacturer — a doctor of aerodynamics who'd earned his pilot's license in France before founding AB Enoch Thulins Aeroplanfabrik in Landskrona in 1915, eventually employing some 800 people. The Thulin G, ordered by the Swedish Navy that same year, was the company's first major military contract and the first Swedish-designed military aircraft to be procured in numbers, funded through public donations. German Benz engines were meant to power the type, but wartime shortages delayed deliveries until 1917, when the seaplane finally entered service on neutrality patrol duty along the coast. Despite careful aerodynamic design work, it proved difficult to handle both in the air and on water, and was retired in 1922. Thulin himself didn't live to see the type through its full career — he died in 1919 when his aircraft broke apart mid-air during a display near Landskrona.

This aircraft, individual number 15, served throughout the type's full 1917–1922 run. It was dismantled from the 1930s onward and sat in pieces for decades until Svensk Flyghistorisk Förening rebuilt it for Flygvapenmuseum's reopening in 2010.
