Wikipedia: Submarine sandwich
A submarine sandwich, also known as a sub, grinder, hero, hoagie, Italian sandwich, po’ boy, wedge, zep, or torpedo, is a popular Italian American sandwich that consists of an oblong roll, often of Italian or French bread, split lengthwise either into two pieces or opened in a “V” on one side, and filled with various meats, cheeses, vegetables, spices, and sauces. The sandwich has no apparent generic name, and major US cities have their own names for it. The usage of the several terms varies regionally but not in any pattern, as they have been used variously by the people and enterprises who make and sell them. The terms submarine and sub are widespread and not assignable to any certain region, though many of the localized terms are clustered in the northeast United States, where the most Italian Americans live.

You folks might relish a victory sundae, or even go for the blackout soda advertised in the window of the South Grand boulevard drug store in St. Louis. But we’d think it over a while before putting in an order for that dive bomber sandwich.

4 August 1977, Washington (DC) Post, “Please Pass the Subs--Er, Hoagies, Er...,” pg. E10:
Submarine, he (Howard Robboy of Temple University, who wrote an American Speech article on sandwich names—ed.) found, is the most popular name for the sandwich, followed by hoagie, poor boy and grinder. In some cities they go by more than one name, such as Philadelphia, where one finds both hoagies and submarines. Other names are torpedo (Reno, San Antonio, San Diego), Italian sandwich (Louisville, Reading, Allentown), hero (New York City and Newark), rocket (Cheyenne and Cincinnati), bomber in Buffalo, mufalatta in New Orleans, Cuban sandwich in Miami, wedgie in Weschester County, N. Y. and slame in Berkeley. Norristown is the only place it is referred to as a zeppelin, and Madison the only place one finds it as a garibaldi.
