Sub collision off Holy Loch 40+ years ago?

Here's one few people know about: https://en.wikipedia.org/wiki/USS_Von_Steuben_(SSBN-632)

On August 9, 1968, while operating submerged about 40 miles (64 kilometers) off the southern coast of Spain, the USS Von Steuben (SSBN-632) was struck by a submerged tow cable connecting a tug and a merchant tanker called the Sealady (Sealady was a liberty ship previously named Bengt H. Larson (1959) and before that was named Alan Seeger (1954)). Due to the merchant being under tow at the time of the collision, the ship had no engine noise for the submarine to detect its presence. When it became apparent the submarine had lost depth control and steering, but not knowing why, the submarine conducted an emergency main ballast tank blow, which resulted in the collision of the submarine and the towed ship. The submarine suffered external damage to the sail and superstructure. After local repairs at the submarine squadron facilities in Rota, she reported to Groton, Connecticut, for more detailed repairs at the Electric Boat Division of General Dynamics Corporation, after which she resumed deterrent patrols out of Rota.

The Sealady sank in the harbor of Cadiz, Spain in plain sight of the submarine base at Rota.

Thanks for the info and update.



The contract to build Von Steuben was awarded on 20 July 1961 and her keel was laid down there on 4 September 1962.



Decommissioning and disposal

Von Steuben was decommissioned on 26 February 1994 and stricken from the Naval Vessel Register simultaneously. Her scrapping via the Nuclear-Powered Ship and Submarine Recycling Program at Bremerton, Washington, began on 1 October 2000 and was completed on 30 October 2001. Von Steuben's age from delivery to disposal was 37.2 years.

37 years is a long time to serve.

collision left a nine-foot scrape in the Madison. According to
Anderson the two submarines came within inches of sinking one
another. The Madison proceeded to Holy Loch, Scotland, to effect
repairs. The U.S. Navy refused to comment on the incident. http://www.skeptictank.org/treasure/GP5/SOVNUK.TXT
edit: in tracking what happened to the Victor class Russian sub involved (no mention so presumably all good) I feel sorrier for the Russians: http://www.globalsecurity.org/military/world/russia/pl-casualties.htm

The article never said 160 nuclear missiles but rather 160 nuclear warheads. 16 missiles X 10 warheads or MIRV's a piece = 160 warheads although specs say the newer versions carried 3 MIRV's a piece as you said. This is the A3 you mentioned at the time of the collision.

It also could carry the Poseidon missile.

Quote: Poseidon could deliver up to fourteen W68 thermonuclear warheads[1] contained in Mark 3 reentry vehicles to multiple targets. The high-re-entry-speed design was intended to counter Sprint-type terminal ABM defenses. See Atmospheric re-entry for blunt body theory.

That would be 16 missiles X 14 = 224 Mirvs unless I'm reading this wrong. The author of the original article may just have been confused.


Great links and good reading though.

OH NO correct away! I had considered MIRV's incl the Poeidon C-3 but couldn't get the count:

The A3 was the first Polaris to have multiple reentry vehicles. The Polaris program started development in 1956. USS George Washington, the first US missile submarine, successfully launched the first Polaris missile from a submerged submarine on July 20, 1960. The A-2 version of the Polaris missile was essentially an upgraded A-1, and it entered service in late 1961. It was fitted on a total of 13 submarines and served until June 1974.(1). Ongoing problems with the W-47 warhead, especially with its mechanical arming and safing equipment, led to large numbers of the missiles being recalled for modifications, and the U.S. Navy sought a replacement with either a larger yield or equivalent destructive power. The result was the W-58 warhead used in a "cluster" of three warheads for the Polaris A-3, the final model of the Polaris missile.

The confusion thus arises: If the USS Madison even had the latest W-58 version in 1974 as of the collision date, and if that: 'three war heads' per silo-thus I assumed the "lesser of two weevils" (this being a Naval forum) and went with a dramatic Newspaper typo error on the assumption: 'Ya gotta sell papers'..assuming the W-58 makes it 48 warheads imho. https://en.wikipedia.org/wiki/UGM-27_Polaris <(enlarges)Transfer of a Polaris missile between USS Proteus and USS Patrick Henry at Holy Loch

You may well be right Aktung. It's really hard to know the exact count there. It still makes you think about the destructive power though.

[Mr Quatro]

I'm just glad that they never had to be used

I think the first boomers use to be called "Peace Keepers"

They had one that was named the USS Will Rogers who said, "I never met a man that didn't like" carring 16 missiles with only the Lord knows how many warheads on each one.

Do you think they are independently targeted or just add to the final conflict?

Seems almost impossible, uh? To target up to ten (10) warheads on each missile.
