This is the Junkers Ju 87C, the first carrier-based derivative of the the famous Ju 87 "Stuka" ("Sturzkampfbomber", dive bomber). It's mostly identical to the B model, with the addition of folding wings, an arrestor hook and a sturdier landing gear. Only one ptototype is known to actually having been built, since the carriers for it never materialized.
