Rocket engines?

I took a picture of this jet plane transporter at the Mobile Bay Battleship Museum in Mobile. I believe they are dual rocket engines, are they? Not for sale, but still neat.

 

Nailhead for sure.

 

I meant Nailhead. Woops.

 

Must have needed some serious torque to tow those planes.

 

actually, it dont take much to move a plane around a tarmac. remember, its all flat as hell

 

buick nailheads without a doubt. looks 50's. interesting that they would have alternators and not generators though.

 

It's even got a louvered hood!
