Is there canon information regarding the fate of the Klingon Bird-of-Prey that was re-christened "HMS Bounty"?
It was last seen floating in San Francisco Bay at the end of The Voyage Home, as a backdrop to Kirk and friends playing with whales in the water.
By some standards, it should be a famous ship.
It was the last vessel to be nose-to-nose with the original USS Enterprise.
It was the last ship to orbit the planet Genesis before its demise.
It probably has the distinction of being the first Klingon Bird-of-Prey to be captained by a non-Klingon — for several months, for that matter.
It's probably the only Klingon warship to have been to the surface of Vulcan (certainly true in pre-Khitomer Accord times, and likely even after the Accord).
It's probably the only (full-blown) Klingon warship to have been to the surface of Earth — in multiple centuries, for that matter.
It's probably the only K'Vort class warship to have been to the 20th Century.
It's probably the only Klingon warship to ever have an aquarium installed in it.
It's probably the only Klingon ship to have intimidated a whaling vessel.
It managed to return the AWOL Enterprise crew, a recently resurrected Spock, a Terran marine biologist from the 1980s, and two humpback whales also from the 1980s to 23rd Century Earth.
Finally, it saved Earth from certain destruction at the hands of a space probe that only speaks to whales.
Fame aside, the ship's grounding on Earth would probably represent an immense tactical advantage for Starfleet at the time. Is there any canonical information about what was done with the ship by Starfleet?
Related enough to be part of this question: Did the capture of the Bounty influence any subsequent design decisions of Federation starships or of Birds-of-Prey? (This should be treated as a sub-question of the main question, regarding the fate of the ship.)
