Svenska Aero AB, after WWI a clandestine subsidiary to Heinkel of Germany, later a more decent license manufacturer of Heinkel aircraft, began in the beginning of the twenties to build up a design capacity of their own. The company stipulated some basic principles: their aircraft were going to be biplanes with fuselage, rudder and landing gear of steel tubing. The wings and fuselage were going to be covered by canvas with steel panel in certain places. But business did not advance very well. The Air Board did not regard the small company as trustworthy and competitive enough.  
So the naval advanced trainer SA-10 Piraten (the Pirate) was a gamble that did not make any success. The Air Force had very little interest in the Piraten, but still placed an order of one single aircraft, mostly as an encouragement to Svenska Aero AB. The aircraft got the Air Force designation Ö 7. After initial trials, it was delivered to the Wing F 2 at Hägernäs in January, 1929. After about 650 hours in the air, it was written off in 1937. In the first part of its lifetime it was marked with the Air Force number 210, later changed to 2610.
The Ö 7 was a rather conventional design. Many technical solutions were typical Heinkel ones. The aircraft was powered by one 7-cylinder Armstrong Siddeley Lynx air-cooled radial engine of 215 hp. It carried no arms.
Svenska Aero also managed to sell one single Piraten to the Latvian Air Force in 1929.
