The Aeromarine AS was a seaplane fighter aircraft evaluated by the US Navy in the early 1920s.

Other than the vertical stabilizer, it was configured as a conventional two-bay biplane on twin pontoons, with two seats.

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.
