Naval Airman John Topman, 25, was sentenced to five and a half years for crashing a BMW convertible while travelling at 79mph in a 30mph area. He was almost three times the legal alcohol limit.
His passenger Cheryl Link, 27, married with a young son, suffered severe head injuries and her life support machine was switched off a week later.
She and Topham had to be cut from the wreckage after he lost control of the vehicle and careered along a pavement before demolishing a lamppost and hitting railings.
He admitted causing death by dangerous driving, and was jailed, banned from driving for six years and faces being discharged from the service.
Passing sentence, Judge Roger Ibbotson said: 'Nothing I do or say can alter the catastrophic consequences of your conduct. The aggravating features are the excess speed and alcohol you consumed.'
Mrs Link, of West Yorkshire, had been on a night out with her husband in her hometown of Todmorden when she decided to go to a party with friends, including Topham and Andrew Krogulski, owner of the BMW.
She had the car's keys because she had moved the vehicle earlier that evening and was first to drive the car before Topham took over.
He stalled the car five times before setting off, and after the crash was found to have 220 microgrammes of alcohol in 100 millilitres of his blood. The legal limit is 80 mg.
