If you qualify, and retire after age 60, you can stay on the Raytheon plan for Medical and dental. You just pay the full amount (Raytheon’s part and your part).
I just retired so, if comes out of your retirement check, and is pretty seamless.
I am not sure if there are other qualifications needed, but I did have a bunch of years. You can call or chat with the Raytheon Benefit center or find someone in HR who knows the answer.
