| 释义 |
Passive Underwater Fire Control Feasibility System (or Study) (PUFFS) was a passive sonar system for submarines. It was designated AN/BQG-4 and was primarily equipped on United States Navy conventional submarines built in the 1950s beginning with the {{sclass-|Tang|submarine|4}}, and also those converted to GUPPY III or otherwise modernized in the 1960s. It was also equipped on the nuclear-powered {{USS|Tullibee|SSN-597}}. A version known as "Micropuffs" was fitted on {{sclass-|Oberon|submarine|2}}s for the Royal Australian Navy, and as Type 2041 on the Upholder-class for the British Royal Navy. This class still serves in the Royal Canadian Navy as the Victoria class, where Micropuffs is known as BQG-501.[1] The system was notable for three tall, fin-like domes topside, except on Micropuffs installations. The system was retained on several submarines transferred by the US to foreign navies. It was associated with long-range passive detection of targets for the Mark 45 nuclear torpedo and other weapons. Most submarines backfitted with it were also lengthened 12-16 feet to accommodate additional electronics and plotting rooms. It was also planned for {{sclass-|Thresher|submarine|5}} and {{sclass-|Sturgeon|submarine|4}} nuclear submarines, but was not fitted on them except Micropuffs experimentally on {{USS|Barb|SSN-596|2}} and {{USS|Haddock|SSN-621|2}}.[2] With the exception of the four Canadian Victoria-class submarines, all PUFFS-equipped submarines have been disposed of or preserved as museum ships.
