1.2 megatonne is large isn't it? In the article^0 where I discovered this (a, so far, interesting history of French and Chinese programs), I also found this part^1 interesting: TN 75 Warhead In 1984-1985 Defense Minister Paul Quiles tasked the CEA to design a miniaturized nuclear warhead for the MSBS M45 SLBM, a variant of the M4. In response, the CEA declared that it could 'achieve a warhead/ re-entry vehicle which is virtually invisible to radar' by 1994.15 The CEA launched the TN 75 warhead program, which was tested numerous times up until July 1991, when testing ceased. According to a report by the Defense Committee of the French National Assembly, 22 tests were conducted to develop the TN 75. The TN 75 warhead is a miniaturized, hardened, thermonuclear warhead. A new coating material and a 'very precisely computed shape' are said to provide the TN 75 re-entry vehicle with 'a very high penetration' capability that also reduces the warhead signature. I? The warhead is much lighter than the current TN 71 (deployed on the M4B) 18 The TN 75 is in the natural progression towards warhead miniaturization, hardening, safety, and stealth, but the tight weight and volume constraints of this system forced design compromises that, when viewed from the prospect of a CTB, caused French officials to be concerned about the long-term reliability of the warhead. It is likely that the 1 October test conducted at Fangataufa, with a reported yield of 110 Kt, was probably a full-scale test of the TN 75. 0: https://news.ycombinator.com/item?id=36010490 https://news.ycombinator.com/item?id=36010490 1: French and Chinese Nuclear Weapons Testing, p. 46
