NIGHT FIGHTER (P-38M)
The P-38M, known as the "Night Fighter," was equipped with a state-of-the-art radar system, (an AN/APS-4 AI radar pod mounted under the nose on a modified bomb pylon) which was operated by a guy crammed in behind the pilot under the bubble canopy.

DROOP SNOOT
The P-38J (so-called "Droop Snoot"), was typically the lead plane on level bombing missions. The Droop Snoot was equipped with a Plexiglas nose and (replacing the more well-known P-38 fire power of machine guns and cannon) an ultra-secret Norden bomb sight. The bombardier was in the nose. The original color scheme was olive-drab-over-gray camouflage, and was most often associated with the 8th AF in Europe -- although they were also flown in the CBI theater. "American Eagles" covers many of the P-38 variances, including the Droop Snoot.
I don't know how they were used but they were made.
