The HMS RHYL was a 12l class anti-submarine frigate, of the British Royal Navy.
It was launched by lady Macmillan in 23 February 1959, and it was commissioned in October 1960.It served the Royal Navy until it sunk as a target, in 1985.
The HMS RHYL was also known as F129. Its engine was rated at 450bhp but it was written somewhere, that the pressure charged engines went up to 1000bhp.When this baby was up for an good old fashion oil change, it would empty a 205 liter barrel of engine oil and at full power, it would eat 23.5 gallons of fuel every hour. Just so you have an idea of what that means, most cars fuel tanks are around 11-12 gallons.
