What is the reference for the USCG cutter being the last U.S. ship to have the 3"/50 mount? I reported to USS San Bernardino (LST-1189) in summer 1992 and we still had two twin 3"/50 mounts. They were removed by SRF Yokosuka in late 1992 or possibly 1993 and replaced by Mk38 25mm mounts.RZid (talk) 06:57, 22 November 2008 (UTC)

I found a reference to the Biddle and her 3"/50 shooting down a MIG here: The fact that a 3"/50 shot up a MIG 21 is more of a testament to her crew than to the gun itself. Oldnavyvet (talk) 20:16, 18 April 2009 (UTC)Oldnavyvet

I thought in the 1980's most of the Cold War Auxiliaries and Amphibs (amphibious ship) had half of their 3"/50s replaced by Phalanx CIWS (maybe in some case all 3"/50s removed). Of those craft, some originally had a fire control system also installed, that was later removed as a cost saving measure. Also for cold Ware Era- some mounts had shields / covers that were only plexiglass (low weight, only provided protection against sea spray, wind, and Very light fragmentation) Wfoj2 (talk) 01:14, 5 June 2013 (UTC)

I don't really know how to do this so I'm winging it here. If I screw this up would someone please fix it? I was a Gunner's Mate on the ElPaso and can confirm the two after mounts (33 and 34 (34 was my mount)) were removed in the Portsmouth yards right after I left the ship in Nov of 1976, but she still has both forward mounts installed. (She's mothballed in Philly and I pass by and give the old girl a salute now and then). (B.W. Behling - USN '74-'80)

Biddle[edit] Has details on the July 1972 incident. The incident is summarized by DANFS, "On the night of the 19th, five MiG's attacked Biddle in two raids. In the first raid, the guided-missile frigate's Terrier missiles destroyed one of the intruders. She claimed a possible kill in the second raid and credited it to her gun batteries."[1]. Doesn't sound certain that the 3"/50 was credited. --Dual Freq (talk) 01:41, 17 April 2009 (UTC)

You only read the summarization by DANFS.,In the full official command history ( credits a possible kill with the 5 inch or 3 inch guns. Other testimony on the website ( indicate that the radar for the 5 inch gun was broken, and all the anti-aircraft fire was from a 3"/50, which probably crippled or downed a Mig aircraft., [(User:Oldnavyvet)|] • contribs) 00:20, 7 July 2009 (UTC)

List of Ships[edit]

I am restoring the deleted list as I disagrre with the single editor's characterization as "pointless". The list illustrates just how common the gun was for a specified period. The list also illustrates the general size range of ships mounting the gun during that period. I suggest the list might be expanded to include the ships carrying earlier marks of the gun, if desired. I believe such additional listing would illustrate the relative importance of the cold war anti-aircraft gun in comparison to earlier marks.Thewellman (talk) 02:24, 4 September 2010 (UTC)

Mark 10 and Mark 12[edit]

The two Mark X was installed on Battleship Texas in July 1916 (per my copy of the armament of page of the ship's Log Book. The eight Mark XII were installed in 1921, per Log Book IronShip (talk) 18:21, 15 November 2010 (UTC)

Are you certain those were 3"/50 guns rather than 3"/23 caliber guns?Thewellman (talk) 00:50, 16 November 2010 (UTC)

USS Conestoga mounted a 3"/50 caliber gun[edit]

The USS Conestoga, lost in 1921, was recently found. It mounted a 3"/50 caliber gun. Reference:
