A submarine boat; esp., Nav., a submarine torpedo boat; -- called specif. submergible submarine when capable of operating at various depths and of traveling considerable distances under water, and submersible submarine when capable of being only partly submerged, i.e., so that the conning tower, etc., is still above water. The latter type and most of the former type are submerged as desired by regulating the amount of water admitted to the ballast tanks and sink on an even keel; some of the former type effect submersion while under way by means of horizontal rudders, in some cases also with admission of water to the ballast tanks.
Being, acting, or growing, under water in the sea; as, submarine navigators; submarine plants.
The question of whether a computer can think is no more interesting than the question of whether a submarine can swim. Edsger Dijkstra
I think a submarine is a very worthwhile weapon. I believe we can defend ourselves with submarines and all our troops back at home. This whole idea that we have to be in 130 countries and 900 bases... is an old-fashioned idea. Ron Paul
When you're on a submarine you're usually underwater for months at a time, and you don't get to Skype or make phone calls. When you get messages, they're maybe two sentences. They're very short. Jessy Schram
I wrote 'Yellow Submarine' for the Beatles. I wrote the screenplay for 'The Games,' about the Olympic Games. I wrote 'Love Story,' both the novel and the screenplay. I wrote 'RPM' for Stanley Kramer. Plus, I wrote two scholarly books and a 400-page translation from the Latin, and I dated June Wilkinson! Erich Segal
I must confess that my imagination refuses to see any sort of submarine doing anything but suffocating its crew and floundering at sea. H. G. Wells
