The US Navy has proposed ending production at 2 Zumwalt class DDG-1000, and making up the difference with additional DDG-51s, and incumbent Republican Susan Collins opposes this while Democratic challenger Tom Allen supports it.
The total amount of dollars from the Navy would be similar, but the Burkes have more local content, as the Zumwalts are made from modules from all around the country (the better to spread the pork around to many Congressional districts)and then assembled at Bath Iron Works, so the Burkes mean more money for Maine, which should be a selling point for Allen.
