Whilst the Navy began their own long range project, the Army disliked the design and began working on their own project in secret. 
It would use a more powerful engine, the fuselage would be increased by length and so would the wing span. The result was something less than satisfactory that actually had less projected endurance than the original. I thought this was incorrect and only gave it around 40 secs more increased flight time.
