There is very little product overlap so this is categorically false. UTC makes aircraft engines, commercial jet interiors, and avionics. Raytheon makes missiles, radars, and ISR equipment. Please explain how you make a missile in a a turbine engine factory.
You can load one of those puppies up with 22 air to air missiles, have a forward F-35 pass along target information, and light them up from the F-15. One team. F-15 is a missile truck that can go Mach 2.2.
Ask because it goes Mach 2.2 it is probably the only fighter vehicle that can launch a hypersonic glide weapon, at least from what the early generation is likely to look like.
