Actually, the P-38M didn't lose any appreciable performance with the addition to the AN/APS-6 radar or the addition of a 2nd crewman and was more than suitable than the P-61A as a night fighter. Even with the improved 2250 hp R-2800-65 engines, the P-61A was slower than the P-38M at all altitudes and had a lower maximum ceiling (33,100ft for the P-61A compared to 40,000ft for the P-38M).
The British also after tests weren't impressed by the Black Widow and felt the night fighter version of the Mosquito was far better than the Black Widow.
As I mentioned earlier, the definitive version was the C model and that wasn't introduced until a couple of weeks before the war ended in the Pacific and never saw any action.

Ack-Ack,
You're throwing out more performance figures while completely missing the point. I said
effectiveness, not performance. A F1 car performs a hell of a lot better than a school bus, but I wouldn't haul kids in it. Night fighters fly
long missions in an unforgiving environment. Radar range and crew effectiveness are
essential. The P-61 is superior on both counts.
As far as the Mossie goes, you're correct, but we were talking about the P-38M. The Brits did prefer the Mossie to the Widow. Does that surprise
anyone? Keep in mind also that those Mossie Mk XVII's, XVIII's, and XIX's, as well as later models
all had the SCR-720 radar from the P-61.
Night fighters aren't simply fighters that happen to fly at night. Their design requirements are completely different. Long endurance, a powerful radar to find enemy bombers, coupled with devastating firepower to take them out quickly when visibility is very poor or non-existent, are the key requirements. The Widow fills all these requirements far better than the P-38M.
