Curtiss HA
![]() HA Designed by Capt B L Smith of the US Marine Corps as a two-seat patrol fighter floatplane for use in the Dunkirk-Calais area, the HA - known unofficially as the "Dunkirk Fighter" - was intended to combat the Brandenburg float fighters. The HA was built at the experimental plant of the Curtiss Engineering Corporation. Of conventional wooden construction with fabric skinning, the HA was powered by a 425hp Liberty 12 engine and proposed armament was two synchronized 7.62mm Marlin machine guns and two Lewis guns of the same calibre on a Scarff mounting in the rear cockpit.
