The Supermarine Scarab was a military flying boat, based on the Sea Eagle and Sheldrake but with a pusher engine, specially designed for the Spanish Navy.
Twelve were eventually built and delivery to the Spanish Naval Air Service for use in the bomber/reconnaissance role during the Rif War.
It was fitted with a .303 in (7.7 mm) Lewis gun and a bomb load of 1,000 lb 454 kg.
