P-61 Black Widow with missile

[pampa14]

I share with you some pictures showing a flying P-61 with a missile under the fuselage. Does anyone know what kind of missile is this and was used operationally? The link also contains photographs of the plane now testing some kind of jet engine. Photos can be viewed by visiting the link below:

The P-61 was the main vector used to test the Gorgon IV missiles. These are the ones that can be seen under the wings, bearing ramjet engines - in the last pic.
As for the one under the fuselage - it looks more like a test-dummy for checking on missile aerodynamics.
