<p>The Lockheed Hudson Mk.III was a significant improvement on the earlier versions of the aircraft. One serious problem with the Hudson Mk.I was its limited defensive firepower. In an attempt to solve this problem the Mk.III was given three extra .303in machine guns, one in a retractable ventral position and two in beam positions, giving it a total of seven guns and removing a blind spot below the aircraft.
</p><p>The Mk.III was given more powerful Wright R-1820-G205A engines, providing 1,200hp at take-off and 1,050hp at 7,500ft, powering Hamiltan constant speed propellers. The Mk.III also featured the stronger fuselage of the Mk.II. Lockheed designated the Mk.III as the Model 414.

A total of 428 Mk.IIIs were built before the start of lend-lease. Of these 241 were given extra fuel tanks in the wings, and given the designation Mk.III(LR), while the earlier aircraft became the Mk.III(SR). 371 of these aircraft served with the RAF, 54 with the RNZAF and 3 with the RCAF
