Bench Grass is a blog about the history of technology by the former student of a student of Lynn White. The main focus is a month-by-month retrospective series, covering the technology news, broadly construed, of seventy years ago, framed by fictional narrators. The author is Erik Lund, an "independent scholar" in Vancouver, British Columbia. Last post will be 24 July 2039.

A Technological Appendix to Postblogging July 1951, II With Some Public Engagement, Even: MiG Alley
In the course of a bit more than a century of aviation, the air has seen its share of the ancient tradition of deniable war. For example, the Condor Legion and Republican aircraft smugglers in Spain, the AVG in China, and the American volunteers of the Ethiopian air force. Probably the single most currently relevant example is one I have been postblogging: The clandestine participation of the Soviet 64th Fighter Aviation Corps in the Korean War. Clandestine, in that Soviet pilots flew aircraft with North Korean and Chinese insignia. Everyone knew what was going on. The secret existed only because it was in everyone's interest to pretend that it was secret. Although I do not find numbers for the personnel side of the Russian auxiliaries, the Wikipedia account says that there were 297 Sabres available in theatre facing 950 MiGs at the time of the 27 July 1953 ceasefire, flown by Chinese and North Korean as well as Soviet pilots.
So that's an occasion when the pilots of one nuclear power faced off against another under a convenient veil of ignorance and also with the pilots of one of the powers further insulated from the brute realities of great power politics by a collective action system in which there was some guarantee that, between a provoked American President and a final nuclear confrontation, there would interpose an angry Clement Attlee or avuncular Winston Churchill.
We have seen UN pilots playing the numbers game in the contemporary press, with a final claim of 792 MiG-15s shot down against 78 Sabres. A more recent estimate indicates a kill ratio closet to 1.3 to 1 in favour of American F-86s.This is, however, exclusive of other Allied jets and piston planes, and the point of the fighting was to drive off the B-29s bombing the Communist staging area on the Korean side of the Yalu around Sinanju, a name I cannot type without free associating.Which I probably should have repressed harder, since it turns out I was reminiscing about a yellowface performance..
It was the failure of the B-29, and not the F-86, which proved to be the crisis of the air war, since it was deemed necessary to maintain pressure on the airfields around Sinanju to prevent the Red Air Force from contesting air superiority over the battle front. The fact that the crisis did not eventuate does not change the fact that there was a bit of a "Fokker panic" going on in Korea in the fall of 1951. The USAF needed a new bomber, urgently. And while the aircraft in question was not ready in time for Korea, the USAF did get one, and that is the story on which this little technological appendix hangs.

The Bishop's Sea: Wage Slavery
Oops! Turns out that the Statute of Labourers was passed in the twenty-fourth year of Edward III. Although I was looking for a fashion-plate sort of image, and everyone knows that gay men are fabulous, right? Gaveston's gloves, at least, look like fine Moroccan leather.

A Continued Technological Appendix to Postblogging Technology, October 1951: British Nuclear Submarines, What's Going On, Here?
This is a pretty famous boat these days, HMS R3. It is the best photographed of 10 R-class boats built during WWI, and I see from my hard drive that it has appeared around here before. Designed specifically for high underwater speed as submarine hunter killers, they were fairly unsuccessful due to not being able to actually find their targets. Evaluating the USN's extensive trials of USS Albacore from 1953 to 1960 (but in particular a 1955--56 series), Norman Friedman called attention to another aspect of the R-class's unfortunate performance, their poor underwater handling. He points out, somewhere in The Postwar Naval Revolution, that the R-class were in the range in which simplified fluid dynamics modelling fails, much as is the case with the transonic flight regime in aerodynamics. Just as postwar aerodynamics depended extensively on full-scale models due to the inability to extrapolate from wind tunnel testing, so the Albacore was a good way of getting past the limits of theory to a good hull form for Skipjack and later nuclear submarines.
Whether any of this features in the Admiralty response to WWI-era experience with the R-class, the fact remains that another R-class, R4, was retained in service until 1934 as a high-speed underwater target. The whole idea of a submarine optimised for submerged speed with a "teardrop" hull was no novelty for the postwar Admiralty, is what I'm saying, and it is hard to believe that anyone ever thought that it was.
Unbelievable, but because of the October, 1952 decision to cancel the British nuclear submarine programme, one that I want to hold up to the light and squint at for a bit. Seriously. What's going on?
