Sikorsky has nothing to do with it. Military helicopters (and Sikorsky helos) are a dying breed. Look at what is happening in Ukraine and look at what the U.S. Air Force is doing with their fleet of Pave Hawks. They're already decommissioning the premier active CSAR squadron in two years (the 55th at Nellis) and have divested further production of HH-60W's. Also, look at the winner of the Army FVL (Future Vertical Lift) competition which is (not) Sikorsky but their competitor Bell/Textron. If I owned Sikorsky stock I'd be selling it. If I worked at Sikorsky I'd be looking elsewhere.

So, Sikorsky is a non-player in the nuclear first strike arena.

HOWEVER, I would look at Groton and the sub base there. That IS (and always has been) a first-strike target. But other than that Connecticut is a military "Black-hole" with nothing of significance in this state. NYC is, however, a juicy target for multiple strikes and "look" for it to become a solid sheet of glass if the unthinkable were ever to become reality. Connecticut to be the recipient of literally TONS of irradiated nuclear fallout which would turn this state into a desert wasteland.

Again, no worries. It'll be over so fast you'll never be bothered by it. Just the blindness if you had been looking in the direction of a detonation and then radiation burning if close enough or inhalation asphyxiation if further away.
