text: # Aeromarine AS
  
  The Aeromarine AS was a seaplane fighter aircraft evaluated by the US Navy in the early 1920s.
  
  ## Development and design
  
  Other than the vertical stabilizer, it was configured as a conventional two-bay biplane on twin pontoons, with two seats. The sole example of the original design, designated AS-1 had an inverted fin. After evaluation testing, the Navy ordered two aircraft, designated AS-2. The AS-2 had cruciform tails and larger radiators, and ailerons on both upper and lower wings.
