3 November 1942:
Kiska. USAAF 11th AF B-24 "Liberator" heavy bombers raid the shipping in the harbor. After the alarm has been given, all submarines in the harbor crash-dive immediately. RO-65 dives, but with her conning tower hatch and main induction valve still open. The quartermaster attempts to secure the lower hatch, but the inrushing water shoves him aside.
The boat is heavily flooded and her stern receives a 30-degree down angle, until it touches the seabed. Seventeen sailors in the aft compartments and two machinists’ mates from the diesel engine compartment drown. A total of 45 sailors escape through the forward torpedo tubes. After the bow has lost all buoyancy, RO-65 sinks at 51-58N, 177-33E.
LtCdr Egi survives the accident and is posted Chief Equipping Officer of RO-107.
1 August 1943:
Removed from the Navy List.
Kiska. RO-65 is surveyed by divers from the USS SAFEGUARD (ARS-50). 
 Author Brian Garfield claims that Major Wilbur Miller, USAAF sank RO-65 and then was himself shot down.
 The divers find RO-65's diving planes in a horizontal position, rather than pointed downward as they would be if she dove to escape the bombing. This finding tends to support the argument that her loss was due to an accident, except that there is external structural damage to her pressure hull and all her conning tower material lays off the side of her hull. Although this supports the bombing argument, it could be argued that the damage happened after her sinking.
