What does the fact they are named snubfighter have to do with their surviabilty? The last definitions of fighter types I read, aka the ones in the Essential Guide to Warfare, lists snubfighters as a middle ground class between the superiority fighters like the TIE Fighters and Interceptors and the traditional heavy bombers, best represented in FFG IMO by the blastboats.
To slightly edit and quote part of the snubfighter article on Wokieepedia:
"Snubfighter was a slang term used to describe a type of fighter which usually carried a crew of one or two. The snubfighters were equipped to attack ground targets and warships along with other fighters. Because of this role they typically carried missiles or torpedoes in addition to laser or blaster based weaponry. They also often include a hyperdrive to allow planet based fighters to attack targets in nearby systems, or to allow deployment from carriers without forcing the carriers to enter battle directly."
