Cobb was one of many civilian vessels taken into the Coast Guard during WWII. She had been constructed in 1906 as the coastal steamer Governor Cobb, and was taken over in 1943. Such a vessel would normally be unremarkable, but Cobb was fitted with a landing platform for experimental helicopter operations, in the very first days of shipboard helicopter operations. In this role she pioneered the now-routine business of landing helicopters aboard ships. Cobb was scrapped in 1947.
