were initially tasked with developing an aero-engine to compete with the latest German inline six-cylinder models. Although BHP's design was projected to produce 300 hp (224 kW) the engine's output came in below expectations. The original name given to engine was the 200 hp BHP. The

Three steel cylinder liners were screwed into a single iron casting which formed the head. A single steel stamping formed the cooling water jacket for groups of three cylinders. It is notable that the
Siddeley Puma's cylinder heads and water jackets are made of aluminum.

The
Adriatic was one of a series of upright water-cooled inline aircraft engines produced by Beardmore and its subsidiary companies. Production of these engines had started in 1913 when Beardmore acquired the rights for licensed production of the

The
Adriatic's cylinders were constructed in groups of three with each block being made from a single aluminum casting. The relatively large and intricate aluminum casting was challenging to produce which led to significant production delays.
