It always aggravates/amuses/annoys me to read technical journals where claims are made that are not true. Not only not true but well known to be not true within the community concerned.

The latest example of ignorance of this sort that I have come accross (it dates from 2006, so not that recent, except to me) is in this article in  Undersea Warfare, The Official Magazine of the US Submarine Force (maybe it should be considered for publication of the week on Have I Got News For You). There it is asserted that the sinking of the Belgrano by Conqueror in 1982 was the first torpedo fired in anger against a warship since 1945. The problem with this is that Pakistan Navy Daphné-class submarine Hangor, on 9 December 1971, fired three torpedoes (probably French L5's) at the ships of the Indian Navy's 14th Frigate Squadron sinking the Khukri (a type 14 frigate).

The further significance of the Hangor/14th Frigate Squadron incident is that it is the first, and so far only, known use in anger of homing torpedoes post WW2.
