THE DBF PIN
Probably none of today’s submariners know the origin or the significance of the Diesel Boats Forever (DBF) pin. Most former Diesel boat sailors are also ignorant of its origins even though it is worn with pride on many SubVets vests.
The last diesel attack boat built for the US Navy was commissioned in October 1959 (1). At that time there were five classes of nuke boats along with two “one off” designs in various stages of construction and pre commissioning trials along with USS Nautilus SSN-571, and the four Skate class boats in operational status (2). The diesel boat force made up predominantly of modernized fleet boats (Fleet Snorkels, Guppy 1A’s, Guppy 2’s, Guppy 2A’s, Radar picket, Regulus missile, troop carrier, and hunter-killer conversions), six Tang’s plus Darter, Growler, Greyback, the two Salmon’s and the three “B” girls had become the source of pre-commissioning crews for the nuke boats. There was a steady stream of 9901’s passing through the diesel boat force, spending seven months onboard learning the boat and earning their dolphins before departing for nuke school. A smaller number of career enlisted electricians, machinist mates, enginemen, and electronic technicians also volunteered for the nuke program. Admiral Hyman Rickover personally interviewed all officers applying for the nuclear power program as well as many of the senior enlisted submariners. Tales of Rickover’s interviews consistently reported on his efforts to intimidate and discredit the accomplishments of the officer interviewee’s, alienating many who interviewed with him. Disturbing reports from senior enlisted veterans of the nuke boat navy in favorite submarine “watering holes” ashore indicated Rickover’s new operating philosophy was at work in the engineering spaces. “Don’t trust enlisted engineers.” Nuke trained officers consistently checked, double checked, and triple checked the work and system lineups of the enlisted engineers, a major change to the long standing professional relationship between enlisted and officer submariners. In addition, “front-enders” the non-nukes, were reporting excessive wardroom focus on the engineering plant at the expense of the historic mission of the submarine. They were also describing the “no-touch” rule from the reactor compartment aft. If you were not a nuke, you couldn’t touch any part of the engineering plant-period. You could learn it in theory, identify major components, valves and panels, but that was it. Gone was the traditional submarine qualification program that demanded standing all watches under instruction as well as rigging all compartments for all evolutions. Lost on most submariners was the reason Rickover imposed the new operational Philosophy which is best summarized by Gary E. Weir (3)
By early 1967 total nuclear submarine crews numbered in excess of one hundred counting blue and gold SSBN crews with sixty four nuke boats (forty one of which were SSBN’s) in commission. The thirty seven Sturgeon class nuke boats would start to commission with the lead ship in March of that year. The Diesel boat fleet in contrast numbered slightly over one hundred in commission with most of the modernized fleet type boats nearing the end of their useful lives. Former SSR’s, SSK’s, and Fleet Snorkels would start to decommission within eighteen months to be followed shortly by the guppy conversions.
More and more Rickover trained officers were appearing on squadron and force staffs bringing with them Rickover’s operational philosophy. It was apparent to all that the diesel boat navy were dinosaurs soon to be extinct along with their officer community who were either unwilling to become nukes or passed over by Rickover as unfit to become nuke boat engineers in order to ascend to command of a nuke boat (4). Diesel boats were still conducting most of the non-deterrent submarine operations including “special missions.” Nuke attack boats were “wowing” many with their performance and potential along with occasional contributions such as “a mission of great value to the government of the United States of America.” The nukes were not without their teething problems however. It was not uncommon for a nuke boat to be unable to get underway as scheduled due to an “engineering problem.” A refueling every three to four years also required a shipyard stay of from eighteen months to two years again reducing the number of nuke boats available for operations. So it was left to the diesel boats to pick up the slack.
‘Dex’ Armstrong (5) describes the thinking of the enlisted smokeboat sailor during these years.
This brings us to the DBF pin. In 1969 USS Barbel SS-580, the lead ship of the last class of diesel boats built for the US Navy was deployed to WesPac. While on a “special mission” in early 1970 the control room gang got into one of those nuke boat vs. diesel boat discussions.
It was pointed out during the discussion that on a number of occasions a diesel boat would have to get underway for a “broke-down” nuke boat again proving the superiority of smokeboats over unreliable nuke boats. Someone suggested there ought to be a pin for smokeboat sailors, something like the new Polaris Deterrent Patrol Pin for “boomer” sailors, for the times you had to take a nuke boat commitment because they were broke- down. A contest was commissioned to design the pin. ETR3(SS) Leon Figurido’s winning design was a broadside view of a guppy boat with SS superimposed on the North Atlantic sail. There were two bare breasted mermaids, one on the bow and one on the stern facing in with arms extended. Completing the design was a ribbon underneath the boat with holes for stars, and centered on the ribbon the letters “DBF”. ETR3(SS) Figurido received appropriate recognition for his winning design along with a prize of some sort, now long forgotten. Upon Barbel’s return to Yokosuka the design of the DBF pin was hand carried to a local manufacturer of nautical gewgaws where a batch were cast and brought back to the ship and sold at cost to Barbel crewmembers that began to wear them ashore. As the DBF pin grew in popularity within the diesel boat community it continued to be cast and sold in shops around Yokosuka eventually making its way to Pearl Harbor, San Diego, and on to the east coast. Most “smokeboat” sailors assumed a gold star would be placed in the ribbon for each diesel boat served on. However, it was confirmed to the author years later by Capt. John Renard, USN RET. Skipper of Barbel at that time, a star was to be placed on the ribbon for each time a diesel boat you served on had to get underway for a broke-down nuke.
The DBF pin continued to gain in popularity among current and former smokeboat sailors who wore them with pride as either a pin or on a belt buckle, all the while collecting the ire of the senior nuke officer community. As the wholesale decommissioning of the fleet type boats occurred during the early 70’s scores of career electricians and enginemen were forced to “surface” as there was no room for them on Rickover’s boats. Their designation was changed by BUPERS from “SS” to “SQ” indicating they were excess to submarine force manning requirements although they were still allowed to wear their dolphins. Soon they too would be gone along with their collective histories. In 1973 Rickover issued an edict that Midshipmen would no longer go on summer cruises on diesel boats. Rumor had it that too many were showing up at his interviews with “bad attitudes” about nuke boats picked up on their summer cruise on the smokeboats. It was reported in favorite submarine hangouts ashore that on more than one occasion nuke boat skippers banned the wearing of DBF pins by their crew members, typically “front enders” the non-nukes, implying that to do so would indicate disloyalty to the nuke submarine force. In the mid 70’s the DBF pin went into the display of submarine insignia maintained at the Pacific Submarine Museum then located at the Submarine Base, Pearl Harbor. The caption alluded to an “unofficial” insignia worn by a disappearing breed of submariner nostalgic for the days of diesel boats.
In July 1975 the last guppy submarine in US service, USS Tiru SS-416, decommissioned in Charleston SC. A handful of the guppies sailed on in foreign service into the late 90’s with two, ex-USS Cutlass SS-478, and ex-USS Tusk SS-426 continuing to serve today in the Republic of China (Taiwan) navy as training boats. The last diesel attack boats in US service were USS Darter SS-576, USS Barbel SS-580, USS Blueback SS-581, and USS Bonefish SS-582. They decommissioned between 1988 and 1990. Two Tang class boats, ex-USS Tang SS-563, and ex-USS Gudgeon SS-567, recently decommissioned in the Turkish Navy with ex-Gudgeon slated to be Turkey’s museum submarine. The Turkish skipper of ex-Tang when asked about the difference between the German designed and built replacement boats for their retiring ex-US boats is reported to have said, “American submarines are built for war, German submarines are built for export.” (6)
It’s ironic that 15 years after decommissioning of USS Blueback SS-581 at the Submarine Base in San Diego, a Swedish Navy Type A-19 Gotland Class Air Independent Diesel Boat is conducting weekly ops there to “familiarize” US Navy ASW forces with the operating characteristics of advanced non-nuclear submarines. When the Swedish crew comes ashore on Friday after a week at sea they still look and smell like the smokeboat sailors of old. Our current crop of submariners avoids them.
The DBF pin, originally designed by a USS Barbel SS-580 crewmember as an unofficial insignia to recognize the diesel boats ability to fill-in on very short notice for broke-down nuke boats, now resides with pride on the blue vests of Submarine Veterans who qualified and served on smokeboats. Today the DBF pin is the unique symbol of the professionalism, discipline, and camaraderie of American smokeboat sailors who sailed on, unloved, unwashed, and underpaid as their era was coming to a close. DBF!
