A peace activist breached security at one of the country's top RAF bases twice in 12 hours.
Anti-nuclear campaigner Juliet McBride walked into the RAF base
Juliet McBride says she got within five metres of nuclear missile warheads at RAF Leeming in North Yorkshire and wandered unchallenged.
Ms McBride, of Southampton, says she has tracked nuclear convoys, and in November followed one as it arrived at the base.
The RAF has confirmed an intruder got into the base in November, but would not comment on nuclear weapons.
She said: "I did find at one point a farmer's fence, but it was down, all I had to do was step through it.
"I got to what I thought was the perimeter fence, so I turned and walked along it and then after about 100 yards there was another compound.
"I walked a bit further and there was a road, and then I was walking up the road with compounds on my left and my right, and the one on my right said X-fighter squadron and I realised I was right in the middle of the base."
Ms McBridem, who is involved with the campaigning group Nuke Watch, said the base security did not see her, even though she was touching a fence without hiding in any way.
