Off the top of my head would be Electric Boat, if they have stock.
Electric Boat is a division of General Dynamics.
There are a few good trade rags out there which you should with regularity. Government Acquisitions and one called Procurement something or other... All companies bidding or winning contracts from small to large acquisitions list there. I’m no longer in the mode so I am a bit rusty as to the in and out of keeping informed. Perhaps a reliable financial contact could help with the current trade rags. Try Clark Howard or perhaps Kudlow websites for info as well.
That is General Dynamics. It includes Electric Boat and Land Systems (M-1 tank) divisions.
I think they are United Technologies. Or General Dynamics. I cannot remember which.
