Who bought out Raytheon?

I'm curious to know, who exactly was the buyer that acquired Raytheon? Was it another major defense contractor looking to expand their portfolio, or perhaps a private equity firm with deep pockets and a strategic vision? Could it have been a foreign entity seeking to gain a foothold in the US defense industry? And what motivated this acquisition - was it a desire for Raytheon's advanced technology, its market share, or something else entirely? I'm eager to learn more about the details of this transaction and the motivations behind it.
