The Navy didn't go for it but were sufficiently interested to order a Model 12-A as the XJO-3 for carrier tests of the tricycle landing gear. The aircraft was flown off the
Lexington during August of 1939.
A revised Model 24 was later proposed with non-supercharged Allison V-1710s, during the war Lockheed proposed the Model 822...basically a P-38H with a strengthened airframe, folding wings and arresting gear.
So USMC/USN night-fighter units?
