The Skybolt crisis The incoming Kennedy administration expressed serious doubts of both Skybolt and the US deterrent force in general. Robert McNamara was highly critical of the US bomber fleet, which he saw as obsolete in an age of ICBMs. Skybolt was seen simply as a means of continuing the existence of a system he no longer considered credible, and given the rapidly improving capabilities of ICBM inertial guidance systems, a precision strike capability with free-fall bombs would no longer be needed. McNamara was equally concerned about the UK also having its own nuclear force, and worried that the US could be drawn into a war by the UK. He wanted to bring the UK into a dual-key arrangement.
