The final, and the most built, series of the Mitchell, the B-25J, looked less like earlier series apart from the well-glazed bombardier's nose of nearly-identical appearance to the earliest B-25 subtypes. Instead, the J followed the overall configuration of the H series from the cockpit aft. It had the forward dorsal turret and other armament and airframe advancements. All J models included a pair of fuselage package,conformal gun pods each flanking the lower cockpit. Each pod containing two .50 inch Browning M2s. -wiki
