The S.P.C.A. 30 M.4

  THIS "multiplace de combat," manufactured by the Society Provencale de Constructions Aeronautiques, possesses a number of interesting features, the most striking of which are probably its twin fuselages. The low cantilever wing is in three sections, the centre section connecting the two fuselages. In the middle of the centre section is a nacelle which houses the pilots and a navigator-gunner, who is also the bomb aimer when the aircraft is equipped for bombing.
  The pilots' cockpits are in tandem and are fitted with dual controls. Aft of these cockpits is a position for a downward firing gun. This position may also accommodate the photographic equipment and bomb racks. The two engines are carried in the noses of the twin fuselages, in each of which a gun ring is fitted ait of the trailing edge of the wing. Two "droppable" fuel tanks are carried, one on each side of the central nacelle. Either Lorraine 18 Kd. 650-h.p. engines or Hispano-Suiza 12 N brs. engines of the same power may be fitted.
