A classical action for open superstring field theory has been proposed which does not suffer from contact term problems. After generalizing this action to include the non-GSO projected states of the Neveu-Schwarz string, the pure tachyon contribution to the tachyon potential is explicitly computed. The potential has a minimum of V = −1/32g2 which is 60% of the predicted exact minimum of V = −1/2π2g2 from D-brane arguments.
