Good observation.
I can barely discern that sentence and cannot read the one above it.

Isn't the Thunderbolt a female?

Aren't all sirens female.

I'd like to see Invasion USA to learn to what they are referring.

MST3K (mystery science theater 3000) riffed on the Invasion USA movie (mst3k episode 602). I'll have to watch it again since it's been awhile.
Nice vintage t-bolt in that pic!
I wonder how long Federal took to design and test the T-bolt before it began selling them?

OT to this post: the movie Rocket attack USA also features sirens in attack mode towards the end of the movie.

This is probably irrelevant, but aestetically speaking IMO the Thunderbolt is the best looking siren ever produced. I'm surprised more of them aren't seen in art photography, they're just so interesting looking.

You can really see that here.

Invasion USA was essentially the first Red Dawn. I haven't seen it but from the info I have found about it it was about an invasion but the invading country isn't named in the movie. From what I gather they were obviously communists. I think it was a low budget thing that was filmed in a week.

No!
The 2t22 is a most attractive homely siren wearing her cute little cap.

The Thunderbolt would be beautiful with a gracefull round horn instead of a crude four-sided exponential projector.

Well, in terms of sheer sound output . . .

I can't imagine anything goofier looking than a Thunderbolt with a round
horn. That welded steel square horn is what gives it it's tank-like look.
The whole Thunderbolt is built like a tank. The C series started getting
a bit whimpy but that was just the blower that was changed.

Amen.

What's the difference between the C series and the other ones? Curious.

A Thunderbolt with a round horn would probably look (but not sound) like an ACA Hurricane. The Whelen Vortexes are so girly-cute.

The Series C was the last generation of T-bolts made. The series A was the 1st. Both look similar except the A had a bigger cast iron blower. The B had a differnet chopper motor and a longer chopper tube
