Notes for a Future Exapnsion

Typing up some of the criteria for my dissertation, thought I'd dump them here for a latter date --Pickle 10:23, 29 March 2006 (UTC)[reply]

The criterion to qualify for this was, in effect, written specifically for Britain, the nation had to have made; “substantial progress in the development of atomic weapons” and where improvements could be made to the existing “atomic weapons design, development and fabrication capability”

Source - US Public Law No. 85-479, 85th Congress, 2nd session quoted in Pierre, Andrew J "Nuclear Politics : The British Experience With An Independent Strategic Force, 1939-1970" 1972, p141

“The cooperating nation must have achieved considerably more than a mere theoretical knowledge of atomic weapons design, or testing of a limited number of nuclear weapons. It is intended that the cooperating nation must have achieved a capability of its own in fabricating a variety of atomic weapons, and constructed weapons manufacturing faculties, a weapons testing station and trained personal to operate each of these facilities”.

Project E

All mention of Project E seems to start around 1958 - was this part of this agreement? I have no reference at the moment to say one way or the other.

Project E was the agreement for US nuclear weapons to be carried on RAF V-bombers but under US custody and with US release for use. It was also used to enable B28 or B43 bombs to be carried on Valiant bombers assigned via SACEUR to NATO as part of its tactical bomber force. This came to an end when the Valiant was grounded in late 1964 with metal fatigue problems.

Most of my information on Project E comes from Humphrey Wynn's "RAF Strategic Nuclear Forces" official history, and whilst this talks a lot about the weapons and their usage, it doesn't apparently talk of the commencement of Project E. Soarhead77 (talk) 14:07, 20 November 2008 (UTC)[reply]

Is Project E part of NATO nuclear sharing agreements, rather than this MDA? Nuclear weapons and the United Kingdom#Deployment of U.S. tactical nuclear weapons discusses U.S. weapons assigned to UK deployment, but doesn't yet really go back to the early days as the info in Project E. Rwendland (talk) 23:16, 20 November 2008 (UTC)[reply]

I'm not sure to be honest - it may actually pre-date it. This is at the heart of why I asked the question. Do you know when the nuclear sharing agreement started? Humphrey Wynn says that the final end of Project E came in 1969 when the last US custody weapons carried by RAF Germany Canberras was returned to the US. There were various end points prior to this - the UK based V-bomber force part ended in 1962 when UK made nuclear weapons became more available and the RAF TBF Valiants assigned to NATO via SACEUR ended in 1964/5 when the Valiants were grounded, but might well have carried on if the Valiants had not been grounded, or they had been replaced by Vulcan 1s or 1As - something which the government of the day weren't interested in because primarily of the cost implications. (This was contemporaneous with the cancellation of TSR-2, P1154 and HS 681). What this book doesn't tell me is how it came about in the first place! In Appendix 9 of Wynn's book (which I drew heavily on in creating the Project E article) is a list of weapons supplied under Project E and the earliest shown is October 1958 against the Mk 5 entry. Soarhead77 (talk) 10:46, 21 November 2008 (UTC)[reply]

I'm not sure either. I suspect reading A Constructed Peace: The Making of the European Settlement, 1945-1963 (Chapter 5: Eisenhower and Nuclear Sharing), Marc Trachtenberg, 1999, ISBN 0691002738 might shed some light on this. It's been on my TOREAD list for a long-time, but I haven't got round to doing an inter-library-loan for it. If you're in London, Westminster Library has a copy according to WorldCat. If the Valiants were under SACEUR, doesn't that imply NATO control, which implies the nuclear sharing agreements (Program of Cooperation agreements I recall)? NB does Wynn explain how US control on nuclear weapons was implemented in the early Canberra/Mk 7 days? (I suspect not very effectively, as in the German/Turkish quick-reaction alert airplanes sitting at ends of runways "guarded" by a single 18-year-old U.S. sentry with a rifle. Chapter 11 of Ross Anderson's Security Engineering is worth a read online if you've not seen that.) Rwendland (talk) 12:39, 21 November 2008 (UTC)[reply]

Also interesting are pages 85-96 of the online RAND book Commitment to purpose : how alliance partnership won the cold war. Nothing on Canberra/V-bomber use but a decent historical background on nuclear sharing. On Page 88 it says the Program of Cooperation agreements were made in 1957, which I think started NATO "nuclear sharing", so Project E could be under that. OTOH the footnote on 94 claims the Hunter and Javelin were the main British NATO nuclear oriented airplanes in the 1950s - which suggests the possibility that Canberra/V-bomber US nuclear bomb use was outside NATO agreements. Rwendland (talk) 14:52, 21 November 2008 (UTC)[reply]

That book looks like a good read! I'm nowhere near London, so such things might have to be bought from Amazon. Wynn mentions in passing the security of US weapons. Like the bit about TBF Valiants being fenced off by six foot fences from non TBF aircraft (I suspect this was at RAF Marham). But nothing about 18 year olds with a gun. But all sorts of wierd things went on at that time which would have shocked people if they'd known about it - like setting PAL codes to 00000000...

Wynn doesn't mention anything other than what was then RAF Bomber Command, and the use of Mk 28 or Mk 43 bombs even though there is a note on the page (which I note you've been too) which talks about Mk 28s being carried on CF-104s. AFAIK the Mk43 in particular was designed to be carried by just about anything that could get off the ground. Note that these devices postdated the Thunderjet :-) These two are mentioned as coming under Project E.

The Valiants coming under SACEUR does imply direct NATO control. Some parts of Wynn say the use of the SACEUR controlled TBF came under Project E, some are more equivocal and say this was similar to Project E. Soarhead77 (talk) 16:41, 21 November 2008 (UTC)[reply]

Inconsistant dotting

At 10:54 pm 16 February 2009 UTC Mauls moved the article from 1958 US-UK Mutual Defence Agreement to 1958 U.S.-UK Mutual Defence Agreement citing WP:MOS then proceeded to dot the USes.

Let's examine the relevant section of the MoS.

US and U.S.
In American English, U.S. (with periods) is the standard abbreviation for United States; US (without periods) is the standard abbreviation in other national forms of English and is becoming increasingly common in American English. ... In a given article, if the abbreviated form of the United States appears predominantly alongside other abbreviated country names, for consistency it is preferable to avoid periods throughout; never add full stops to the other abbreviations (the US, the UK and the PRC, not the U.S., the U.K. and the P.R.C.).

Note

The article is not written in American Enlish (using defence not defense).
The abbreviated form of the United States appears predominantly alongside the abbreviated form of the United Kingdom ... obviously.

Therefore what the MoS actually says is exactly the reverse of what Mauls reads it as saying. The article is to be moved back and the dots are to be removed. JIMp_talk·cont 15:57, 6 July 2009 (UTC)[reply]

UK contribution

The transfer of technology wasn't all one-way. The UK had a significant lead in several nuclear weapons technologies and this material was transferred to the US. Re-entry vehicle ('Re-entry heads' in the UK terminology of the time) designs being one notable area. These were tested using the Black Knight launch vehicle, BK04 on 11 June 1959 being the first proper RV test, using a conical RV, re-entering pointed-end first. 3-Dimensional Quartz Phenolic used for the later US and UK RV bodies was also of UK origin. —Preceding unsigned comment added by 213.40.254.15 (talk) 19:23, 4 September 2009 (UTC)[reply]
