2205-644: The XW-59 to the RV. In May, a second working group for the Mark 11 RV was formed. The plan was to introduce the Mark 11 into service in January 1963 with the eventual replacement of all Mark 5 RVs with Mark 11s. In May 1961 it was noted that the weapon's RV and fuzing system would be developed by Avco while Sandia National Laboratories would be responsible for the firing set, external initiators, ESD and housing and mounting structures. The warhead would also be compatible with

2268-457: The XW-59 would be unsuitable for the Skybolt application due to the requirement for free-fall drop delivery option. In March 1961, the Skybolt joint working group met and concluded the initial July 1963 deployment date was unrealistic as flight tests of the weapon had still not been conducted. Further, due to the need for a special ESD, the XW-59 warhead for Skybolt was renamed the XW-59-X1 . As

2331-405: The annual competition. The previous LLNL record of seven awards was reached five times – in 1987, 1988, 1997, 1998 and 2006.
