A Royal Navy sailor raped a female colleague as she lay asleep after a night out, a court martial has heard.
Engineering Technician (Marine Engineering) Kenni Dinnell, is accused of raping the woman at an accommodation block at Portsmouth Naval Base.
Mr Dinnell, who previously served on board the Type 42 destroyer HMS York, appeared before the court martial at the base, known as HMS Nelson.
He denies the alleged attack on a sailor of able seaman (seaman) rank.
Commander Darren Reed, prosecuting, said on the evening of 9 July last year, Mr Dinnell had gone to a male colleague's accommodation cabin at HMS Nelson, where they spent the evening with two female colleagues.
'Drunken and unconscious'
After a number of drinks, Mr Dinnell, the alleged victim and the male friend went to bars and a nightclub in Portsmouth city centre while the second woman went home, the court heard.
Cdr Reed said all three returned to the cabin in the early hours of 10 July, where the friend and the alleged victim went on to have consensual sex.
Then later, after the friend had fallen asleep on the floor and the victim was alone in a single bed, Mr Dinnell climbed in with her, the court heard.
Cdr Reed said Mr Dinnell began to kiss her and, in a "drunken and unconscious" state, she believed it was the friend.
He said "things progressed" and ended up with Mr Dinnell having intercourse with the victim.
Cdr Reed said the alleged victim then realised it was not the friend.
He said: "She pushed him off and said 'no'."
The case continues.
