The RAF women's side have been confirmed as Inter Services champions after the Navy beat the Army 2-0 in Portsmouth.
After winning against the Navy and drawing with the Army recently, the Air Force knew they were likely to win the title.
The RAF needed a Navy win or draw to seal the title, and goals from Rosie McDonnell and Kate Bowden confirmed victory for the Senior Service.
The game started slowly, but the Navy soon went close through their captain Nat Banister. She let fly from nearly 30 yards and looked destined to score, but the ball flew inches wide of the post.
Minutes later, the Navy had the lead. A great pass from Ciara Boylan fed the run of Anthea Kaptein and her scuffed shot was already heading in when McDonnell touched it over the line.
The Army did have a goal disallowed for offside, but in the second half, the Navy secured the win with a second goal.
It was a sublime chip that left the Army goalkeeper stranded and Bowden could celebrate a well-taken goal.
The 2-0 win means the Navy have beaten the Army for the first time in Inter Services history, which is an achievement Banister is pleased with.
She said: “It’s been a long, long time but we have made history tonight.
“Although we have come second in the competition, we have turned the Army over and we are made up with that."
